酸性ガスを除去するための構成および方法
Document Type and Number:
Japanese Patent JP2005538841
Kind Code:
A
Abstract:
A plant includes an absorber ( 105 ) that receives a feed gas ( 10 ) at a pressure of at least 400 psig and comprising at least 5 mol % carbon dioxide, wherein the absorber ( 105 ) is operated at an isothermal or decreasing top-to-bottom thermal gradient, and wherein the absorber ( 105 ) employs a physical solvent to at least partially remove an acid gas from the feed gas ( 10 ). Such configuration advantageously provide cooling ( 108 ) by expansion of the rich solvent ( 21 ) generated in the absorber ( 105 ), wherein both a semi-rich solvent ( 13 ) generated and recycled to the absorber ( 105 ) and the feed gas ( 10 ) are cooled by expansion of the rich solvent ( 21 ).
