ABYSS® Portable Biogas Analyser

ABYSS ABG® Portable Biogas Analyser

Biogas Monitoring System

The ABYSS ABG® Portable 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.

The ABYSS ABG® Portable Biogas Analyser is housed in a robust and compact enclosure and offers a large variety of features such as on-board BTU calculation and a built-in sampling pump, calibration valves and printer.

APP

Portable Gas Sampling Probe

The APP portable gas sampling probe is especially designed for portable applications where easy handling, safe and reliable operation as well as easy maintenance are required. The low weight and innovative design guarantees a perfect operation in a wide range of conditions for short and medium term mobile measurements.

Sampling Probe

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 APS portable sampling system is designed so that detailed gas analysis can be carried out at any time in any place. The entire sampling system is housed in a compact and robust carrying case which ensures safe transport and easy set-up. All the components can be easily accessed for inspection or routine maintenance.

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.

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

Biogas composition can be used to optimise plant operations and to reduce maintenance tasks.

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
