Abstract
Biogas containing HS and COis upgraded by removing HS using PTSA and COusing two stages of gas separation membranes. The first stage permeate may optionally be used a regeneration gas stream. The second stage permeate may optionally be used a cool down gas stream. The PTSA unit includes two or more adsorbent beds each selective for water, VOCs, and HS over COand for HS over methane.
