Abstract
The invention relates to a process and a plant for removal of acidic gas constituents from synthesis gas by absorption in a physical scrubbing medium. A first scrubbing medium laden with at least carbon dioxide (CO) is supplied to a decompression vessel for depressurization from a first absorption apparatus via a first feed conduit. Furthermore, a second scrubbing medium laden with at least carbon dioxide (CO) is supplied to the decompression vessel for depressurization from a second absorption apparatus via a second feed conduit. The carbon dioxide concentration in the first laden scrubbing medium is higher than the carbon dioxide concentration in the second laden scrubbing medium. According to the invention it is provided that an at least partial commixing of the first and the second laden scrubbing medium is effected in the decompression vessel, wherein the commixing and depressurization affords a partially regenerated scrubbing medium and the first feed conduit and the second feed conduit are arranged such that carbon dioxide desorbed from the first laden scrubbing medium by the depressurization is at least partially absorbed by the second laden scrubbing medium.
