Title:
CO2 collection system
Document Type and Number:
Japanese Patent JP5972696
Kind Code:
B2
Abstract:
A CO2 recovery system includes an absorption tower that brings gas containing CO2 into contact with a CO2 absorption solution to remove CO2 from the CO2-containing gas; a regeneration tower that regenerates a CO2-absorbed rich solution; and a compression device that re-uses a lean solution, from which CO2 has been removed in the regeneration tower, in the absorption tower and compresses CO2 in gas emitted from the regeneration tower, wherein the rich solution has a high pressure, the high-pressure rich solution is subjected to gas-liquid separation by a flash drum, the rich solution as a liquid component separated in the flash drum is introduced into the regeneration tower, and high-pressure CO2 gas as a gas component separated in the flash drum is introduced into a compression device having a predetermined compression pressure.
