WebEmerging Technologies and Biological Systems for Biogas Upgrading systematically summarizes the fundamental principles and the state-of-the-art of biogas cleaning and … The principle of physical absorption is based on variation in the solubility of different gas fractions in a liquid scrubbing solution. A physical bond is formed between the absorbed gas components and the scrubbing liquid. Water scrubbing and organic solvent scrubbing are suitable for biogas enrichment. See more A physical absorption in which the gaseous molecules are bound to liquid molecules with poor intermolecular forces. Thus, the physical absorption process is generally carried out at some high pressure and low … See more It is an emerging technology in which the gases are separated by using temperature difference.
