US 12,599,871 B2 · Exhaust gas scrubber with energy integration

Abstract

A gas scrubber may include an absorption apparatus configured for receiving a gas and absorbing the gas in an absorption medium, as well as an evaporation apparatus configured for evaporating at least a part of the liquid that is introduced. The absorption apparatus may have an introduction apparatus for the gas, an apparatus for circulating the absorption solution that has reacted with the gas, a discharge apparatus for at least a part of the absorption solution that has reacted with the gas, and a cooling system for the circulating absorption solution. The absorption apparatus and the evaporation apparatus can be connected via a heat exchanger such that heat content of the absorption solution that has reacted with the gas is used at least in part for the evaporation.

Dependent claims

A process for scrubbing gas comprising:

introducing the gas into an absorption apparatus;
circulating a circulating absorption solution;
discharging a part of the circulating absorption solution;
concentrating a discharged solution, which is the part of the circulating absorption solution that is discharged, by evaporating at least a part of an absorption medium, wherein heat content of the circulating absorption solution is used at least in part for the evaporating at least the part of the absorption medium;
and
conducting the circulating absorption solution and the discharged solution separately through a heat exchanger, wherein the circulating absorption solution is fed to the heat exchanger as a heating medium and the discharged solution is fed to the heat exchanger in counter-current as medium to be evaporated.
