FEED GAS PRE-PROCESSING APPARATUS

摘要

Disclosed in the present invention is an apparatus for pretreating natural gas. An absorption section and a removal section of a gas sweetening unit (GSU) of the present invention are integrally formed in one column. Accordingly, when an apparatus for pretreating natural gas is installed in a floating offshore plant having a limited space, the installation area is minimized. In addition, when separately forming an absorption tower and a removal tower performed in prior technologies, the inconvenience of the pipe connection can be reduced.
