ENVIRONMENTAL MONITORING

Stack Testing

Ankersmid Sampling

APS Portable Gas Sampling System

The emission of pollutants resulting from a multitude of activities (industry, transport, …) alters the atmospheric composition and degrade air quality. Control of gaseous pollutant emissions in the atmosphere has become a major challenge for the protection of human health and the environment. To avoid these risks, the regulation has established discharge limits thresholds for certain pollutants and requires periodic inspections whose frequency depends on the type of activity (from 3 months to 3 years). Accredited stack testing companies are responsible for conducting short to medium term environmental compliance monitoring tasks in a wide range of industries and processes such as power plants and large manufacturing facilities including paper mill, foundry, waste recycling facilities,  refineries…

Prior to be analysed, the gas extracted from the discharge stack or process duct requires delicate conditioning which mainly consist of particulate filtration and moisture removal. Failure to achieve an efficient sample preparation can results in inaccurate measurements, loss of data or damaged equipment.

While stack testers and local authorities are continuously devoting time and knowledge to optimise the methods and protocols related to short to medium terms mandatory analysis campaign, ANKERSMID® has invested its long time expertise in developing the APS Portable Gas Conditioning Systems in direct collaboration with  leading stack testing companies.

As a result, ANKERSMID® Portable Sampling System APS provides stack testers with  features tailored to short term source testing in a robust and light weight design. The complete systems responds to today’s demand in terms of operation and compliance.

Indoor air quality

 

Air Quality in Submarines

The last generation of conventional submarines allows several weeks of submersion, creating a need for regenerative air purification methods and new air monitoring instruments. Submarine air is a complex mixture of compounds, where the most obvious contaminant is metabolically produced carbon dioxide. Normal eight-hour occupational exposure limits are not applicable on a submarine, instead special long-time exposure limits are set.

A number of air purification methods for submarines are either available or under development, e.g. cryogenic plants, biological plants and solid amine plants. For air monitoring, the OFCEAS method is an interesting option, already in use on-board nuclear submarines.

The main contaminant of submarine air is CO2. In ordinary buildings 1000 ppm is usually considered as a maximum concentration. This value is not based on health effects but on the rate of ventilation. In submarines, higher CO2 concentrations are permitted, usually 5000- 7000 ppm. A submarine atmosphere consists of a large number of contaminants such as ozone, which can be formed in electrical devices and hydrogen, which is formed when the batteries are charged.

To ensure the health of the crew on short and long term, it is important to specify the permitted composition of the submarine atmosphere.

ProCeasNAV-Onboard-air-quality-analyser

Table 1 shows a submarine air specification for a conventional submarine.

Compounds Limit Compounds Limit
NO2 5 ppm NH3 25 ppm
CO2 8 000 ppm O3 0.1 ppm
CO 35 ppm H2 2 %
SO2 2 ppm CL2 1 ppm
Formaldehyde 2 ppm H2O2 1 ppm
Akrolein 0.1 ppm

 

Since the crew is continuously exposed to the submarine air for several weeks, normal eight hour occupational exposure levels are not applicable and special exposure limits must be determined. Maximum Permissible Concentrations (MPC) are set for an exposure time of 90 days for a number of compounds likely to be found in a submarine. They have also set emergency MPC’s for 24 h and 60 min.

The ProCeas® NAV

The ProCeas® NAV is designed for online monitoring of CO2, CO, Freon, H2S, H2, O2, Formaldehyde (…) in nuclear and conventional submarines. The ProCeas® NAV uses the OFCEAS method commercialized by Ap2e of France.

ap2e-CEMS and Process Analysers

The OFCEAS system uses a high-finesse optical cavity to provide path lengths of tens of kilometres. Moreover the OFCEAS technology can also, in certain configurations, take advantage of broadband light sources to provide multi-component analysis, while offering improved sensitivity when compared with shorter path-length methods, such as Tunable Diode Laser absorption spectroscopy (TDLAS).

ProCeasNAV-indoor air quality in submarines

The ProCeas® NAV analyser has been designed to endure large temperature variations, high vibrations and englobes all criteria required by the military environment to assure long-term crew member health in a confined environment.

Some of the gases and measuring ranges available on the ProCeas® NAV are:

Carbon Monoxide CO: 0-1000 ppm – Lower Detection Limit: 1 ppm

Carbon Dioxyde CO2: 0-5% – Lower Detection Limit: 0.01 %

Hydrogen Sulfide H2S: 0-10 ppm – Lower Detection Limit: 0.1 ppm

Freon; R134a and R404: 0-1000 ppm – Lower Detection Limit: 2 ppm

Ethanol C3H6O 0-2000 ppm – Lower Detection Limit: 4 ppm

General characteristics

Response time < 10 sec

No Zero drift and no Span drift – No daily calibration required – No nitrogen, zero air, purge or other carrier gas.

Weight 15 to 20 kg

Dimensions 480 x 240 x 150 cm

Formaldehyde in Indoor Air

 

For continuous ambient and indoor air quality monitoring (real time at ppb levels), the ProCeas® spectrometer is equipped with a laser at a single wavelength used to determine the concentration of a specific compound with an extremely low detection limit and fast response time. The OFCEAS extended optical path and continuous signal feedback provide a high definition spectral response using what is essentially a traditional absorption measurement.

ProCeas

ProCeas® Formaldehyde at HUTCHINSON

As per the international OH&S regulations on Formaldehyde, Hutchinson, subsidiary of TOTAL, evaluated several technologies to implement continuous real-time monitoring of Formaldehyde at their Plant facilities.

The ProCeas® has been selected by Hutchinson as the technology the most suited to their monitoring needs in terms of response time, accuracy and flexibility around the integration within the mainstream of their installation.

Hutchinson uses the ProCeas® to measure various level of Formaldehyde in the air at 3 separated sampling locations: laboratory, offices & entrance hall.

Area Monitors for Sterilant Gas

Hazards of sterilant gases

Since sterilant gases are selected to destroy a wide range of biological life forms, any gas which is suitable for sterilisation will present a hazard to personnel exposed to it. The NIOSH Immediately Dangerous to Life and Health values (IDLH) for the three sterilant gases are 800 ppm, 75 ppm and 5 ppm for ethylene oxide, hydrogen peroxide and ozone respectively.

For comparison, the IDLH of cyanide gas (hydrogen cyanide) is 50 ppm. Thus exposure to even low levels of sterilant gas should not be treated casually and most facilities go to great lengths to adequately protect their employees. In addition sterilizers (as with any mechanical device) can and sometimes do fail and leaks have been reported. Continuous gas monitors are used as part of an overall safety program to provide a prompt alert to nearby workers in the event that there is a leak of the sterilant gas.Steri-Trac Area Monitors - sterilant gas - AquaGas

Monitoring Sterilant

The monitor alarms are typically set to warn if the concentrations exceed the OSHA permissible exposure limits (PELs), 1.0 ppm for ethylene oxide and 1.0 and 0.1 ppm for OH&S and ozone respectively. The PELs are calculated as 8 hour time weighted average values.

In addition to providing continuous monitoring, the better gas monitors include a computer based data acquisition system provides automatic data logging to assist with compliance with OSHA’s regulations and impending alarms that allow users to rectify problems before they become a hazard.

There are several technologies that are commonly used for the detection of sterilant gases, the main three being electrochemical, gas chromatography and metal oxide semiconductor. All three technologies are suitable for ethylene oxide, but only electrochemical sensors are used for hydrogen peroxide and ozone detection.

For ethylene oxide, metal oxide electrochemical sensors provide a low cost, long life detector offer very good sensitivity, fast alarm response times and small size. ChemDAQ gas monitor manufacturers mainly use electrochemical sensors for toxic gases because of their many advantages.

Electrochemical sensors have traditionally suffered from a cross sensitivity problems with other vapours (alcohols are especially troublesome in health care). Cross sensitivity results in false alarms, unnecessary evacuations and eventually a loss of confidence in the gas monitoring system.

AquaGas - ChemDag - Steri-trac

ChemDAQ has developed a proprietary chemical filter that allows the ethylene oxide to pass through but removes most common interferent gases and vapours (including carbon monoxide, ethanol and IPA). The use of this filter allow the ethylene oxide to be detected with all the advantages that electrochemical sensors have to offer, but without the problems of cross sensitivity.

CEMS and process gas analyser

 

A new approach to continuous gas monitoring

The Mamos is a high quality stationary monitoring system for the measurement of up to 6 gases as well as gas temperature, ambiant and differential pressures (Gas Flow) in a large field of applications.

Designed to optimise performance/price ratio, small in size and yet very skilful analyser, the Mamos is the field proven alternative for large, intricate Continuous Emissions Monitoring Systems, as it does not fall behind them concerning functionality, abilities, reliability and is far ahead in terms of expenses.

AquaGas Multigas CEMS

Online monitoring made easy

Fully automated and packed with exclusive features, the Mamos concept enlarges monitoring possibilities and respond to the today’s demands in terms of accuracy, reliability and flexibility. Each analyser is supplied with its own sampling system. The entire system is mounted on a wall mount plate and designed for installation in industrial settings and rough environment. It has a modular construction, and offer a large panel of add-ons to match site specific application requirements. The Mamos minimises the installation and ongoing operation cost until now required to fulfil your monitoring needs.

MAMOS-Multigas-analyser-CEMS-features

Multigas

Depending of the gas matrix and components to be analysed, the Mamos can be fitted with up to 6 different sensors. The combination of technologies (NDIR, TCD, PID, Electrochemical) and the addition of separate gas channels into the same instrument empower flexibility in multigas applications. A unique feature is to allocate a gas channel to sensible sensors. Its design ensures the cells have a limited exposure to gases and therefore extends considerably their respective life-time.

Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities and associated filtration systems are typical applications for multiple gas channels configuration.

In Biogas, the primary gas channel holds the CO2, CH4, Osensors while an additional separate gas channel is allocated to sensible Electrochemical sensors, H2S for example. The two NDIR gas channels can then be used for CO and VOCs.

MAMOS-CEMS-Flow diagram-2

The Mamos offers multiple sensor and method configurations. Here are the measuring parameter for the most common gases. For other gases or different measuring ranges (MR), please consult us.

Continuous IR laser spectroscopy

Applications and References

The ProCeas® and the LaserCEM® are based on the OFCEAS* measuring principle combined with a Low Pressure Sampling LPS (100 mbar absolute) developed and patented worldwide by AP2E (France), for the online analysis of several key gases in industrial, environmental and OH&S applications. It provides measurements with a very high spectral resolution in addition to an exclusive and powerful sampling method (no heated line nor treatment of samples) and an interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

 

Combustion cycle in refineries

With the environmental constraints, Oil companies are looking for optimum energy and environmental efficiency of their burners. Combined cycles boilers optimisation requires accurate simultaneous online monitoring of O2 and CO to ensure both compliance with standards and process control efficiency. The ProCeas, used to track real time the residual rate of O2 (less than 3%), ensures optimal combustion process automation. The accuracy of the measurement is a financial matter: according to the thermal performance of the burner, even a reduction of 0.1% of oxygen in excess represents millions of dollars of savings in the annual consumption of fuel.

Reference: IBIDEN Power Station – Simultaneous SO2/SO3 monitoring at the catalyst outlet according to the oxygen content variation have been done with the ProCeas® analyser.

SOx monitoring

SO2/SO3: AP2E also intends to enhance the approach aimed at combining environmental compliance and process optimisation, even if this seems less obvious to understand at first sight. If today SO2 is correctly measured, this does not fully reflect the sulphur emissions from combustion units subject to this requirement. In the presence of oxygen, SO2 does in effect form sulphur trioxide (SO3), a gas that is much more corrosive than SO2.

LaserCEM

Other chemical phenomena occur, particularly in denitrification (DeNOx), which in the presence of ammonia may lead both to an over-consumption of ammonia and to filter blockages. Therefore, not measuring SO3 entails the under estimation of sulphur emissions, and also additional maintenance costs and over-consumption of reagents. To have continuous and precise knowledge of the SO2 / SO3 couple enables the operator to choose the controlling conditions for limiting the formation of SO3 and its indirect costs.

Biogas

biogas

The processing of gases from biomass (biogas, bio-methane) remains a key step in industrial processes for producing various types of bio-energy, a manufacturing process that requires optimizing.

It is therefore imperative to have the ability to calculate the calorific value of these new gases and to be able to quantify the impurities present there, in order to reduce the risk of damage to facilities, to react quickly in case of malfunction, and to certify the quality of finished products. AP2E has installed several equipment units within the facilities of various players of the world of biogas around the world. The purpose is to analyse the CH4 and CO2 content, as well as the residual concentration of H2S. This is a major impurity which transforms into sulphuric acid in the presence of some moisture. It is a very corrosive acid; consequently it is destructive for the facilities and the engines that burn biogas or bio methane.

The ability to analyse in the same multiplexing equipment the H2S content (which varies according to the time of day) of the “raw biogas” at the exit of the casing serves to determine the use of this biogas and assess its composition and quality. Other compounds may also be monitored by adding specific laser sources, such as the water content, in order to control the efficiency of the condenser. AP2E is also currently studying the analysis of siloxane, another sore point for energy recovery.

Using a continuous analyser as a means of industrial control and economic optimization of production units is for the control of biogas quality. During the combined cycles of biogas generation, the absence of H2S is crucial. It is a major impurity and a source of engine breakage. However, conventional means of analysis have trouble distinguishing CH4 from H2S. Therefore, operators are forced to adopt an excessively prudent approach in the treatment stage with active carbon: it is changed even before it is totally saturated. With a continuous, accurate, and reliable analysis of the level of H2S in the exit of the adsorption bed, we can instead use it until its saturation point and reduce overall costs.

Tests conducted on a site with a valuation of 1 MW showed that the amortization of the analyser could be performed based on this single criterion of active coal consumption in less than a year. Indeed the cost of a monthly activated carbon charge is equivalent to AUD $65,000.

 

Indoor air quality

Fgas monitoring system

References: In 2010, AP2E won an important contract with the DCNS for air quality control equipment for the confined interiors of submarines (on-board crew safety).

In April 2015, European regulations included formaldehyde as a proven carcinogenic product (CMR). In 2014, the ProCeas was certified approved method by EXERA (measurement, control, and automation equipment) and the LNE (National laboratory of metrology and testing).

AP2E is already working in the confined air field (submarines) and is interested in the building sector.  This new classification impacts devices monitoring the exposure to workers or to the public of formaldehyde, Freon, Ethanol… present in the indoor air of industrial sites or sites hosting the public. The ProCeas® Formaldehyde continuously measures these changes with a minimum 10 ppm threshold (maximum 1%).

Food processing industry

The drying field is another good example of application where energy efficiency has to be kept in mind, especially when processing food powders. Water monitoring is useful for avoiding excessive energy consumption (adjust dryer load to obtain minimise the residual H2O content). Online monitoring of carbon monoxide (CO) answers safety concerns. When food powders are dehydrated, the conditions may be such that CO is generated in the dehydrator. Once conditions for generating CO are present, CO tends to increase its concentration very quickly. To keep the CO below potentially dangerous level, it is necessary to detect the first signs of CO which appear above the levels already present in the atmosphere. The ProCeas is actually in operation within ten drying towers in dry food production facilities and has been chosen as the most reliable monitoring equipment by companies leading food processing industry.

Engine emissions testing

The automobile engines sector also remains a major target. With the arrival of the new EURO VI standards since September 2014, manufacturers have been forced to measure many pollutants (NO, NO2, N2O, NH3, CO2, CH4, and ethanol).

ProCeas

Successful testing with ProCeas® was conducted around the world:

– NH3 at Renault and VOLVO (France)

– N2O at Volkswagen (Germany)

– NH3 at General Motors (USA)

– NH3, N2O, NO, NO2 at Sensor Inc. (USA)

In the USA with Sensors Inc. – (www.sensors-inc.com): in May 2012, AP2E signed a contract for supplying ProCeas® analysers for the real-time control of gas emissions of engine test benches in the automotive industry. Sensors Inc. is the leading American manufacturer of real-time testing equipment for gas emissions in the transportation industry. The new range of measuring instruments is marketed in the US under the name of SEMTECH LASAR and it consists of four modules (NH3, N2O, NO, and NO2), each capable of analysing three gases simultaneously.

Natural gas

To be used in the best conditions, so that it limits damage and maintenance of equipment, natural gas must be rid of impurities, especially hydrogen sulphide (H2S), which is very corrosive, and all traces of moisture. Current filtration systems run against, among other things, the problem of measuring residual traces of these impurities because no reliable continuous analysis system was available so far. Today the main players in the “Oil & Gas” market deem the ProCeas® as the most efficient natural gas analyser for continuously and simultaneously measuring traces of H2S (LoD under 50 ppb) and H2O (under 50 ppm), without interference, without any dependence vis-à-vis the constitution of the gas, and with response times under a few seconds

H2O, CO, CO2, and H2 rates

Praxair uses the ProCeas® as an online analyser of H2O, CO, CO2, and H2 rates, in a process for producing syngas from the gasification of coal, oil residue, pet coke, and biomass. This syngas is then used either as a source of energy in a heat and electricity combined cycle process or in a Fischer Tropsch process for producing second-generation bio-fuel. This process requires that the residual H2S generated by gasification have a value of less than 1 ppm to avoid the destruction of the polymerization catalysts.

CO, CO2, H2O, CH4, H2S, NH3 and H2

Midrex is a steel manufacturer that uses a gasification process similar to Praxair’s in order to cogenerate the electricity and heat needed in the manufacture of its steel. AP2E delivered to Midrex complete solutions that have enabled it on the one hand to measure the calorific value of these synthetic gases (by measuring CO, CO2, H2O, CH4, and H2) and also the presence of impurities such as H2S and NH3.

H2, H2O and Cl2

Today, the ProCeas® provides what no other infra-red laser technique could: the direct measurement of hydrogen (H2) and water (H2O) in chlorine (Cl2) without reagents or discharges, and interference-free. The ProCeas® performs measurements with a very high spectral resolution of very low concentrations (under a few ppm), with response times under a few seconds. This analyser also provides a control of the drying (H2O) in a chemical process at Arkema.

OFCEAS & Low Pressure Sampling

Continuous Emissions Monitoring and Process Control

Starting in 2012, AP2E launched the industrialisation of the ProCeas® and LaserCEM® product range, the continuous and multigas analysers using OFCEAS* patented laser spectrometry. This analyser range is based on several innovations, providing very high performance in terms of response time (less than a few seconds) and great accuracy of the analyses (wide dynamic range from ppb to %):

OFCEAS, CONTINUOUS INFRA-RED LASER SPECTROSCOPY TECHNOLOGY

The ProCeas® and the LaserCEM® are based on the OFCEAS coupled to a Low Pressure Sampling LPS (100 mbar absolute) developed and patented worldwide by AP2E (France), for the online analysis of several key gases in industrial, environmental and OH&S applications. It provides measurements with a very high spectral resolution in addition to an analysis system with a simplified sampling (no heated line nor treatment of samples) and an interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

ProCeas

The OFCEAS technology essentially differs from the CRDS (Cavity Ring Down Spectroscopy or Spectroscopy by resonance damping time) technology by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity resulting a resonance phenomenon. With a volume of only 15 cm3, the measuring cavity or cell is equipped with mirrors whose reflectivity exceeds 99.99%, providing an optical path between 1 and 10 km (approx. 10 meters in conventional technologies). The immediate consequence of this phenomenon is the identification of very intense absorption peaks with a very narrow spectral width. Given that the source used is a continuous laser, the system presents very high measurement stability: there is no zero drift and no need for new calibrations.

LOW-PRESSURE SAMPLING SYSTEM

The Low Pressure Sampling (LPS) System allows reducing the sample dew point (vapour pressure) to prevent the risk of condensation. The sampling method is achieved by the use of a sonic nozzle which allows reducing the sampling pressure down to 100 mbar. In these conditions the ambient temperature is almost always above the dew point eliminating the risk of condensation.

r4

  • No Sample heated line required to eliminate condensation: low power consumption, no related ongoing maintenance
  • True Direct Extractive CEMS/Process analyser (no dryer or scrubber)
  • No risk of absorption/desorption typical of high SO2/SO3 application
  • Low pressure accentuate the gas finger print
  • Cost effective multipoint monitoring
  • Standard system comply with ATEX standards

The integrity of the sample is therefore ensured. The very low airflow ensures a verylow response time and a minimal contamination of the system.

OFCEAS Detection limits

All these points enable to both increase the detection sensitivity and  simultaneously reduce the noise, which permits the detection of gases at very low levels of sensitivity (traces of H2S – LOD under 50 ppb, or traces of H2O – under 1 ppm).

ProCeas

Complete pre-calibrated multicomponent (H2S, CO, CO2, H2, H2O, HCl, HCN, HF, N2O, NH3, O2 and CH4) laser Infrared Spectrometer designed for online monitoring of combustion process, natural gas (LNG), pure gas (trace) and ambient air (trace).

 

LaserCEM

The LaserCEM is a complete pre-calibrated multi-component (NO, NO2, NOx, SO2, CO, HCl, CO2, H2O, H2S, NH3, N2O, COS, SO3, CH4, HF) laser Infrared Spectrometer designed for Continuous Emissions Monitoring and compliant to standard EN 15267-3 : 2008 and QAL 1 de EN 14181 . With the announcement of the continuous measurement of SO3 (sulphur trioxide) at the exit of combustion units, AP2E represents the link from an industrial point of view between regulatory measurements (EMC) and optimizing production processes. If SO2 is now properly measured, it does not fully reflect the sulphur emissions from combustion units subject to this requirement. In the presence of oxygen, SO2 does in effect form sulphur trioxide (SO3), a gas that is much more corrosive than SO2. And other chemical phenomena occur, particularly in de-nitrification (DeNOx), which in the presence of ammonia may lead both to an over-consumption of ammonia and to filter blockages. Not measuring SO3 entails the under estimation of sulphur emissions, and also additional maintenance costs and over-consumption of reagents. To have continuous and precise knowledge of the SO2 / SO3 couple enables the operator to choose the controlling conditions for limiting the formation of SO3 and its indirect costs.
