Abstract Biogas, a renewable energy source, is primarily composed of methane and carbon dioxide and other gaseous species. Biogas upgrading for removing CO 2 from raw biogas is a necessary step before the biogas to be used as vehicle fuel or injected into the natural gas grid. Therefore, the present work aimed to propose a low-temperature CO 2 removal process as an alternative to the

in the purified biogas should be less than 3% [11]. biogas and increases the compression and transportation co sts.So, there is an immense need of removal of carbon dioxide from biogas. Biogas production and subsequent purification will CO2 removal technologies rather than going into details on it.

Removal of H 2 S and CO 2 from Biogas by Amine Absorption 135 2. Biogas treatment methods 2.1 CO 2 removal from gas streams CO 2 removal from gas streams has been of great interest, especially in large thermal power plants, due to its greenhouse effect (Romeo et al, 2006). Table 2 compares the different existing technologies. 2.1.1 Absorption

The Use of an Iron Wool Carbon Dioxide Scrubber For home-size systems, a easy solution for getting CO 2 from biogas is an Iron Wool Carbon Dioxide Scrubber Device, which is one which which absorbs carbon dioxide from circulated gas. A carbon dioxide scrubber is a device which absorbs carbon dioxide (CO 2). It was found that biogas can be removed by bubbling it through 10 per cent aqueous solution of mono-ethanolamine (MEA). By single bubbling through a plain column of 6 cm height, carbon dioxide content in biogas was reduced to 0.5-1 per cent by volume from initial value of 40 per cent.

Common methods used to eliminate CO 2 from biogas are: water scrubbing (for example by using iron wool – see below.) membrane systems pressure swing adsorption (PSA) (see -below) chemical CO 2 absorption amine gas treatment CO 2 by cooling and recovering dry ice.

Biogas, a renewable energy source, is primarily composed of methane and carbon dioxide and other gaseous species. Biogas upgrading for removing CO2 from raw biogas is a necessary step before the biogas to be used as vehicle fuel or injected into the natural gas grid.

Carbon dioxide removal is a form of remediation, but it is a more sophisticated and costly step in the “cleanup” of biogas. Normally, the reason to remove the carbon dioxide is to prepare it for injection to a pipeline, or prepare it for vehicle use, like in trucks, buses, or taxi’s, that are converting to burn the pure methane. It is primarily comprises 45-75% (v/v) of methane (CH 4), 25-55% (v/v) of carbon dioxide (CO 2), 2000 ppm of trace element hydrogen sulfide (H 2 S), and ammonia (NH 3). The presence of CO 2 and H 2 S may affect the performance of biogas.
