Purpose of gas monitoring in DRI plant

The use of process gas online monitoring systems at locations such blast furnace gas outlet, converter off gas exhaust and coking gas outlet is very reasonable in order to analyse the fuel gases composition by measuring the concentration of CO, CO2, O2, N2, CH4, and H2. There from the calorific value BTU and the Wobbe Index WI can be accurately calculated. Modern steel plants uses dedicated stationary online monitoring system to monitor the primary constituents of Direct Reduction Iron process gases essential to have a full understanding of the process status and efficiency.

In particular, the energy content of the gases, as described by their calorific value, provides the user with important information about efficient firing of different plants in the steel mill (coking plant, sinter plant, rolling mill, etc.) or a nearby power plant.

High-calorific coke or natural gas is mixed with low-calorific converter or blast furnace gas in mixing stations. This is to adjust the calorific value of the mixture to the requirements of the subsequent consumer and to avoid discharging of valuable gases into the off gas.

The knowledge of the calorific value together with information about pressure and flow rate of the fuel gas enables the user to adjust a constant energy content of the mixed gas using an intelligent control system.

Furthermore, analysis data of the gas analysers are also used to determine the equivalent amount of oxygen that is required to run the combustion process. This results in a stoichiometric and uniform combustion and prevents soot production.

Syngas online monitoring systems

The use of advanced online monitoring systems installed in the heart of syngas processes usually requires integration into air conditioned analyser rooms or shelters to preserve the instruments from harsh plant conditions and corrosive atmospheres. The installation in an area protected from the weather also secures the data/instrument availability by providing permanent access to the analysers – if attendance is required for maintenance or diagnosis.

Systems certified for installation in explosive area (ATEX) may be required in some cases.

Reliable, accurate and application customised online monitoring systems are valuable in DRI and other syngas plants as they allow determining the quality parameters of blast furnace, coke and natural gas essential to process optimisation.

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.

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.

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.

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.

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, O₂sensors 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.

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.

Discharge management

Oil platforms, refineries and Tank farms generate produced water which requires close management. For every country in Oceania, there are regulations setting limits on the amount of hydrocarbons than can be disposed of overboard and a range of different lab techniques that can be used for reporting this amount. The OPAL and PAUTBAC II from SERES IR based analysers can provide continuous measurement of the oil concentrations in the discharge water from oil and gas processing and storage facilities.

Process optimisation

The OPAL and PAUTBAC II from SERES are respectively side stream analyser and oil tank de-watering systems based on IR light scattering. They not only can provide you with extremely accurate monitoring, but also sense for changes in the size of oil droplets and therefore in process conditions. Using the built in IR detector, the OPAL and PAUTBAC II analysers enable early detection of oil traces in all type of water, ensuring fast overview of the process conditions.
As the volume of your discharge water increases, you need a system that will meet your changing demands, work reliably and with minimal operator input required. Having provided hundreds of online monitoring systems worldwide, SERES is the best positioned to assist you along with your water management plan.

Oil Pollution Alarm

Every platform, refineries, industrial process (…) has to recover as much oil as possible, as efficiently as possible. In order to make improvements you need to understand how the current system is working. SERES Environnement manufactures the OPAL (IMO* certified) allowing real-time measurement of oil concentrations at the inlet and outlet of any separator, providing continuous on-line information about the effectiveness of your separators. The OPAL can also trigger a divert valve to route the produced water through a sand filter.

The OPAL is the last generation of detector designed for online and Real-time suspended Hydrocarbons monitoring. It uses Infra-Red scattering to enables early detection of oil in any type of water. Reagent’s free, the OPAL represents the most cost effective solution and matches a large range of application requirements.

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.

CEMS in coal fired power station

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.

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.

Brochure

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

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

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).

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

Pure Gas

The ProCeas® is used by pure gases manufacturers to control the purity of the gas along production line (N2, H2, O2…).

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.

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.

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.

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.

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).

ProCeas

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.
