摘要：
The invention discloses a method of gas separation which pressurizes part of a raw gas issuing from the outlet of an adsorbing tower by employing a compressor portion of an expander compressor, cools the pressurized gas by means of a main heat exchanger, and expands the cooled gas by means of an expansion turbine of the expander compressor, thereby efficiently carrying out gas separation with a simple arrangement.
