Abstract
A plant includes an absorber (103) that operates in a gas phase supercritical region and removes an acid gas from a feed stream (9) at high recovery of the feed stream (10) while producing a high purity acid gas stream (36). Particularly preferred plants include gas purification plants that receive a feed gas with at least 5 mol % carbon dioxide at a pressure of at least 3000 psi.
