CO2 Removal from Biogas by Water Washing System
One method of animal manure disposal is anaerobic digestion (AD). The term anaerobic implies that at least part of the process occurs in the absence of oxygen. Farm AD, or bio-digesters, normally take animal manure and produce combustible gas (“biogas”) and useful solid matter. Most AD units produce a … See more Biogas generated from anaerobic digestion processes is a relatively clean and environmentally friendly renewable fuel. Raw biogas … See more There are a variety of end-uses for biogas. Except for the simplest thermal uses such as some types of heating or odor flaring, biogas needs to be cleaned or processed prior to use. With appropriate cleaning or processing, biogas … See more Internal combustion engines are the most frequently mostly used power plants in AD-CHP applications due to familiarity, cost and ability to simply recover heat.
