Abstract

PURPOSE:To make it easy to control the dew point in the removal of low- volatile components, by allowing a mixed gas composed of at least any of H2, CO2 and CO and a volatile hydrocarbon gas to pass through two membrane modules having different adsorption rates for specific components. CONSTITUTION:A mixed gas composed of any of H2, CO2 and CO gases and a gas of volatile hydrocarbons is allowed to pass through a first-step membrane module through which high boiling-point components in the volatile hydrocarbon gas pass faster than methane. Subsequently, H2, CO2 or CO is separated from the resulting mixed gas by allowing the gas of H2, CO2 or CO to pass faster than the volatile hydrocarbon gas components. For example, by the use of a silicon membrane for the first-step membrane module 1 and a cellulose membrane or a second-step membrane module 2, a natural gas having a CO2 concentration of 6.23vol.% is allowed to pass through the modules, thereby obtaining a pipeline gas having a CO2 concentration of 2vol.%.
