Method and apparatus for cooling and compressing a stream containing CO2 and water

Abstract

Title of the invention: Method and apparatus for cooling and compressing a stream containing CO2 and water. In a cooling, compression and cooling process for a gas containing at least 15% mol CO2, the following steps are carried out: direct contact (T) of the gas (1) which cools with water (5) which heats up, forming heated water (11); cooling of the heated water which is pumped to generate water in a cooling system, the cooling system comprising: an indirect contact heat exchanger (HX 1) which exchanges heat between the pumped heated water and a flow of cooling water (17) from the cooling water system; and a cooling tower (CT) by direct contact to cool at least a portion of the cooling water upstream of the heat exchanger.with the use of condensate (9) from a contact-cooled gas compressor as a water make-up for the cooling system.
