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.

Syngas monitoring

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.

Monitoring locations

The number of monitoring points can vary depending of the degree of automation and optimisation desired by the plant operators as well as the type, quality and stability of the combustible used.

Monitoring locations in Syngas Plant often include

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.

AquaGas Pty Ltd offers a broad range of portable and stationary monitoring systems specifically designed to handle syngas online monitoring requirements.

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.

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.

*Optical Feedback Cavity Enhanced Absorption Spectroscopy: technology developed and patented by the University Joseph Fourier (France), coupled to a Low Pressure Sampling (100 mbar absolute) developed and patented worldwide by AP2E, for the on-line analysis of different gases. By the end of 2010, after two years of R & D studies, the AP2E ProCeas® was the award recipient of the USA “R & D 100” which rewards the 100 most innovative global technologies of the year.

Process monitoring in biogas plants

Why is process monitoring necessary?

Biogas plants are biological systems involving various interacting micro-organisms that anaerobically degrade organic matter. The main product is biogas, a gas rich in methane (CH4) that can be used as a renewable fuel for vehicles or to generate heat or electricity for local use or for use via energy distribution grids.

The degradation involves four consecutive biological processes: hydrolysis, acidogenesis, acetogenesis and methanogenesis.

 

Wasistbiogas

If one of these processes is negatively affected in any way there is an immediate influence on the other processes and the biogas plant can become unstable. Typical process failures include, among others, organic overload, hydraulic overload and ammonia inhibition. Process monitoring can help to understand what happens in a biogas plant and help to maintain a stable process. In many cases, a strongly inhibited micro-organism population or a total crash of the whole plant can have severe financial consequences for the biogas plant operator.

In general, process monitoring in anaerobic or other fermentation processes can help to:

  • Give an overall picture of the biogas process
  • Identify upcoming instabilities in anaerobic digester before a crash happens
  • Accompany a successful start-up or re-start of a plant

The costs of online monitoring are often much lower than the costs and lost revenue associated with re-establishing a biologically destabilised plant.

For example, if a biogas plant has totally crashed it may have to be emptied and filled again with new inoculum. This, together with the necessary start-up period, means that several months can be lost during which the plant could have operated at full load. The financial consequences can be devastating for the plant operator.

Key parameters in Biogas monitoring

Biogas plant

In biotechnological processes, the detailed monitoring of the fermentation product, in this case biogas, provides valuable information. Therefore, it is recommended to monitor both the volume of gas produced and the gas composition. With regard to process monitoring, a change in either gas production or gas composition can be an indicator of process imbalance.

Biogas primary constituents

  • CH4 and H2S measured during the methanation process give a good overall view of the performance of the degradation process and bacterial activity. A decrease in methane content can be a first sign of organic overload, provided that the feedstock mix has not recently changed. Similarly, a sudden increase in H2S can provoke process instability.
  • Simultaneous real-time monitoring of CH4, H2S and CO2 empower process automation (i.e. operation of scrubbers)
  • Before entering the distribution chain, the product must be qualified, again for economic reasons (excess H2S and/or CO2 in the CH4 would make it ‘sour’ and potentially corrosive enough to damage distribution infrastructure)
  • CH4, H2S, CO, CO2 and O2 Continuous Stack Emissions Monitoring required for environmental compliance

 

PROCEAS

Stationary Biogas Monitoring Systemslogo-ap2e

In general, a large variety of devices can be applied for measuring biogas production but in practice, as biogas is of variable gas composition, dirty, corrosive, wet, and produced at low pressure, measuring biogas volume and composition accurately is one of the most challenging parameters at a biogas plant. In the long run not properly designed systems can pose considerable problems due to corrosion, fouling or general deterioration when measuring raw biogas.

AquaGas Pty Ltd introduces the OFCEAS technology and Proceas BioGas analyser  designed by AP2e to address the analytical (online monitoring of biogas primary constituents) and operational (zero drift, minimum maintenance, no consumable, autonomous operation) biogas plants and methanation process monitoring requirements.

AP2e ProCeas BioGas

 

The ProCeas BioGas analyser features two patented technologies:

  • The OFCEAS IR Laser technology for enhanced specificity, selectivity, accuracy and stability (no instrumental response drift.):  The OFCEAS is a self-referencing spectrometer. This means that there is no need to re-analyse a zero and/or a span gas on a regular basis. The “zero” information is contained in the direct measurement spectrum while the “span” information is intrinsic to the analyser (pre-calibrated with 4 OD linear response).

OFCEAS - ProCeas BioGas

  •  The Low Pressure Sampling (LPS) system enabling low-cost installation thank to non-heated lines and reduced maintenance. Lowering the pressure of a gas sample reduces the bandwidth of the absorbance bands. At atmospheric pressure, simultaneous measurement of H2S (ppm’s) in presence of CO2 (10’s %), CH4 (10’s %) can be tainted by cross response / false positive due to spectral overlapping of CO2 and CH4 bands with H2S  information.  If operating at 100 mbar, all absorption bands have narrowed down to the point where there is no spectral overlap of the absorption bands. Cross response have been eliminated. 

OFCEAS Detection limits

When sampling gas from landfill, anaerobic digestion/bacteria and other fermentation processes, the use of a dedicated sampling system is necessary to ensure a specific sample preparation and to preserve your monitoring equipment. Another advantage of the LPS System is the ability to reduce the sample dew point (vapour pressure) to prevent the risk of condensation. The sample extraction is achieved by the use of a sonic nozzle. The sample is taken at a very low pressure (50 to 200 mbar abs, 100mbar nominal). At 100 mbar abs. the ambient temperature is almost always above the dew point eliminating the risk of condensation.

LPS biogas sampling probe

  • No heated line required to eliminate condensation: low power consumption, no related ongoing maintenance
  • Sample does not need to be treated – True Direct Extractive CEMS and Process analyser
  • No risk of absorption/desorption

The ProCeas offers sampling solutions tailored to the needs of the biogas production industry with automated sampling sequences and multipoint monitoring enabling fast, accurate and detailed analysis at various location with a single instrument: Raw biogas (1), processed biomethane (2), vented biogas (3) and stack emissions (4).

  • Field proven technologies in the Biogas production industry
  • Simultaneous measurement of all primary constituents of Biogas
  • Fully automated standalone system (automatic calibration and sampling sequences)
  • Low Pressure Sampling (no sample condensation)
  • Deep particulate filtration
  • PFA and PTFE gas path (essential to avoid loss of components of interest)
  • Fast, accurate and reliable online analysis
  • No drift or deviation therefore minimal calibration requirements

Standard systems are delivered fully integrated in a 19 inch rack suitable for installation in industrial settings (indoor 15-35C). For installation in hazardous area the BioGas Monitoring System is available in ATEX certified version.


 

ABYSS

Portable Biogas Analyser

Ankersmid Sampling

 

Short term measurement during start up conditions

The start-up of a biogas plant is a very sensitive process. Due to slow multiplication of some of the micro-organisms involved in anaerobic sludge and the consequent risk of hydraulic overload, the start-up of a biogas plant can take much longer than in other biotechnological processes. A start-up time of 1-2 months is nothing exceptional in biogas plants.

Therefore, the effort in process monitoring has to be highest during start-up. If the start-up is too fast, a sub-optimal biogas process can be the consequence because the most favourable micro-organisms have not multiplied in the biogas plant. In contrast, a slow start-up can cause a possible loss of income as time is taken to reach full load capacity. The frequency of the measurements should be increased during this crucial process steps.

Poster Process Monitoring in Biogas Plants-v1

The  ANKERSMID Portable Biogas Analyser is especially designed so that detailed gas analysis can be carried out at any time in any place.
