脱硫选择性

Abstract(#br)A study was conducted on hydrogen sulfide (H 2 S) removal from biogas using a novel hybrid polydimethylsiloxane (PDMS) membrane bioscrubber. The effect of absorption liquid pH, biogas flowrate and DO concentration on H 2 S selectivity, removal efficiency and sulfide oxidation were investigated. The process performance at pH 7 was better than pH 8.5 in terms of H 2 S removal capacity and selectivity. Desulfurization selectivity of H 2 S/CO 2 and H 2 S/CH 4 increased along with the increase of gas flowrate (32 l/d) and reached 3.5 and 63, respectively.
