ABYSS BIOGAS Analyser

ABYSS® Biogas

Biogas Monitoring System

The ABYSS Biogas analyser (NDIR and TCD) series is specially designed for continuous and simultaneous monitoring of primary Biogas constituents CH4, CO2, O2 and H2S. Fitted with on board BTU calculation, the ABYSS ABG Biogas fulfils the requirements of medium to large scale wastewater treatment plant, odour control system, landfill, anaerobic digestion and other fermentation processes. It is based on the micro-flow type non-dispersive infrared (NDIR) method for CH4 and CO2 and uses a set of Electrochemical (EC) Sensors for H2S and O2.

Automated removal of tares, condensates and particulates.

Adsorption cartridge

Particulate filter
Efficient system integration
The ABYSS Biogas 19”inch rack mount enclosure fitted with LCD screen, safety filter and built-in flowmeter enables efficient continuous measurement of up to 4 gases in emissions and process gas.
Fast and reliable online biogas monitoring
An automatic built-in gas diluter reduce instruments recovery time in case of high and unstable gas concentrations. The ABYSS analysers are built, calibrated and factory tested in Belgium and certified C.E. by Ankersmid Sampling BVBA.

ASP Stationary Gas Sampling Probe

The ASP Sampling Probe temperature controlled versions (user adjustable up to 320°C) is available in three different lengths and is designed to provide reliability in applications with high acid gases concentration, heavy dust load, and harsh installation environment. The ASP300 provide the choice of different lengths of filter element for three levels of dust load. A 150mm filter suits for most of the applications with dust concentration up to 1g/m3. With the 180mm filter element, a larger filtering surface allows sampling gases containing up to 4g/Nm3 of Dust. For extreme conditions, the 500mm model filter enables reliable sampling gases with dust load up to 10 g/Nm3 as standard and 20 g/Nm3 with the backflush.

AHL Heated Sample Lines

The AHL electrically heated sample lines series is designed for connecting to all type of sampling equipment. The use of heated line ensures that the gas components in the sample stream remain above their respective dew point and thereby eliminates the risk of condensation. Thanks to a modular design and a large selection and combination of options, the heated lines AHL ensures safe and reliable sample transfer within CEMS or process monitoring systems. The ATEX heated sample lines series AHLX are designed to transport sample gas through explosive zone type 1 or 2.

ASS Stationary Gas Sampling System

The ASS Stationary Sampling System is a high performance complete gas conditioning system designed for CEMS – Continuous Emissions Monitoring and process control. The entire gas conditioning system is deliv-ered ready for installation in cabinets, rack or wall mounted. The ASS features fully automated sampling sequences, sample flow adjustment, continuous water vapour and sample condensate removal, particulate filter and a PFA coated heat exchanger coupled with a powerful Peltier cooler. Its design and construction ensure reliable sample preparation without loss and prevents damage on the analysis system used downstream with a sample outlet dew point at 4°C.

Typical Applications

Process monitoring

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

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
