Abstract
A system and method for separating COfrom natural gas, which ensure that no clogging or deterioration occurs in a gas separation membrane even after the gas separation membrane is used to remove carbon dioxide from the natural gas under conditions in which the natural gas is pressurized. First, an HS remover removes hydrogen sulfide from raw natural gas. Then, a compressor pressurizes the natural gas from which HS has been removed. After that, a cooler cools the pressurized natural gas so as to condense components that are a part of the natural gas. A gas/liquid separator removes the condensed components, and a COseparator, including a separation membrane for separating COremoves COfrom the natural gas from which the condensed components have been removed. An expander, which shares a drive shaft with the compressor, expands the natural gas from which COhas been removed and recovers energy therefrom.
