Title:
METHOD AND APPARATUS FOR SEPARATING A FLOW RICH IN CARBON DIOXIDE BY DISTILLATION TO PRODUCE LIQUID CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2022/162041
Kind Code:
A1
Abstract:
An apparatus for separating a flow (1) containing carbon dioxide by distillation, comprising a heat exchange means (E), a distillation column (K), means for sending the flow to be cooled in the heat exchange means to a first intermediate temperature so as to form a liquid flow at a first temperature and at a first pressure, means for dividing the liquid flow so as to form a first fraction and a second fraction (7, 9), means for expanding the first fraction to the pressure of a distillation column, means for sending the first expanded fraction to an intermediate level in the distillation column, means for removing the second fraction from the cold end of the heat exchange means after cooling, means for expanding the second cooled fraction to the pressure of the distillation column, means for sending the second fraction to the distillation column and means for extracting a liquid flow from the column vessel.
