Title:
酸性ガス捕捉プラントからの塩の除去に使用されるイオン交換体の再生
Document Type and Number:
Japanese Patent JP5344934
Kind Code:
B2
Abstract:
A process for the removal of an amine capturable gas from a feed gas stream using an amine solvent, the process comprises (a) contacting the feed gas stream with a lean amine solvent to form a rich amine solvent, wherein heat stable salts are present in the rich amine solvent; (b) stripping amine capturable gas from the rich amine solvent to form the lean amine solvent and an overhead reflux stream; (c) periodically contacting at least a portion of one or both of the lean amine solvent and the rich amine solvent with an anion exchange resin to form a first heat stable salt lean amine solvent; (d) periodically regenerating the anion exchange resin, wherein during the regeneration of the anion exchange resin, at least a portion of the reflux stream is used to wash the amine solvent from the anion exchange resin to produce a second heat stable salt lean amine solvent; and, (e) recycling at least a portion of the first and the second heat stable salt lean amine solvent for use in capturing the amine capturable gas from the feed gas.
