CO2 & CH4 Biogas Analyzer using NDIR Sensor

At Olythe, where innovation meets sustainability, we are delighted to unveil our latest development: the CO2 & CH4 Biogas Analyser. This state-of-the-art instrument is designed for biogas plants and offers unrivalled accuracy and reliability in monitoring carbon dioxide (CO2) and methane (CH4) levels.

 

Why measuring CO2 and CH4 in biogas plants ?

 

Methane and carbon dioxide are produced during the biogas production process by a biological process known as anaerobic digestion. Anaerobic digestion is the decomposition of organic matter in the absence of oxygen, resulting in the production of biogas. 

 

During anaerobic digestion, microorganisms, primarily bacteria, break down organic matter into simpler compounds through a series of metabolic processes. One of the metabolic pathways involved in anaerobic digestion is the production of methane and CO2. Methane is produced when microorganisms called methanogens break down organic compounds such as acetic acid, hydrogen and carbon dioxide.

 

Once biogas has been produced by the anaerobic digestion of organic matter, a purification stage is required to separate the methane from other gases such as carbon dioxide, hydrogen sulphide and moisture. This purified methane can then be called biomethane, which can be used as a renewable biofuel. Biomethane can be used in a variety of applications, including vehicle fuel, heating and electricity generation.

EXPERTISE

Analyzing gases with infrared spectroscopy

A non-dispersive infrared (NDIR) sensor operates by detecting the amount of infrared light at a particular wavelength absorbed by a sample. In this process, infrared light passes through the chamber to the detector. The gas being analyzed absorbs energy at specific wavelengths, causing attenuation in the light detected by the sensor. This attenuation is precisely measured by the detector, enabling accurate determination of gas concentration.

To enhance accuracy, the detector is equipped with a bandpass optical filter that selectively eliminates wavelengths not absorbed by the target gas molecules, ensuring reliable measurements of CO2 and CH4 concentrations in biogas.
