Title:
METHOD AND SYSTEM FOR CARBON DIOXIDE GAS DEHYDRATION
Document Type and Number:
WIPO Patent Application WO/2017/017711
Kind Code:
A1
Abstract:
In a system for dehydrating carbon dioxide gas, the carbon dioxide gas is cooled by using a turbo expander (21), and the power extracted by the turbo expander from the carbon dioxide gas is used in the system for compressing the carbon dioxide gas. The cooled carbon dioxide gas is fed to a knock-out drum (22) to remove free water therefrom. The carbon dioxide gas from the separator is introduced to a secondary dehydration unit (11) and recompressed to the required pressure for carbon storage or for EOR operation.
