Abstract
Abstract The separation performance of hydrogen sulfide–methane mixture by a nanoporous carbon membrane called selective surface flow (SSF) membrane is described. The membrane selectively permeates H2S from CH4, producing a CH4 enriched gas at the feed pressure. Experimental data for the separation of H2S–CH4 mixtures using feed-gas H2S compositions of 10–50 mol.% and feed-gas pressures of 0.45–1.14 MPa are reported. The partial pressure of H2S in the feed gas is the key variable for establishing the separation performance of the SSF membrane. The H2S rejection–CH4 recovery data can be empirically correlated using a simple equation with a single adjustable parameter which is a function of feed-gas H2S partial pressure. The membrane separates H2S–CH4 mixtures very efficiently when the partial pressure of H2S is moderate (>0.2 MPa) even if the total feed-gas pressure is low (0.45 MPa).
