METHOD FOR DEACIDIFYING A GAS USING A PLURALITY OF STEPS FOR CROSS-FLOW CONTACT WITH AN ABSORBENT SOLUTION

摘要

The invention relates to a method for deacidifying a gas using a plurality of staged steps for cross-flow contact with an absorbent solution, wherein a plurality of cross-flow contact stages are implemented in a series of contact areas in which the gas flows in an essentially horizontal direction while intersecting with the liquid that flows in an essentially vertical direction. The gas to be treated, which arrives via pipe 1, flows consecutively into the cross-flow contactors C1, C2, and then C3, in a substantially horizontal direction. The absorbent solution arriving via pipe 7 consecutively flows into the contactors C3, C2, and then C1. In each of the contactors, the liquid flows in a substantially downward vertical direction.
