Abstract: PURPOSE: A method for separating high purity methane gas from landfill gas and an apparatus for refining the methane gas are provided to recycle the methane gas and utilize the methane gas as a fuel by efficiently implementing a methane gas separating process. CONSTITUTION: Landfill gas is successively dehumidified, desulfurized, and desiloxanized in a pre-treating process. The pre-treated gas is compressed and cooled. The compressed and cooled gas is introduced into a double-stepped hollow fiber membrane to separate carbon dioxide. The ratio of a first membrane area to a second membrane area is between 1:1.5 and 1:3.0. The transmittance part of the second membrane is re-circulated to a process in prior to the compressing process. The remaining part of the second membrane eliminates nitrogen and oxygen based on pressure swing absorption.
