Abstract:
A method for recovering a condensable gas from a mixed gas by using a condensable gas recovering apparatus comprising:a compressor for compressing a mixed gas comprising a condensable gas and an incondensable gas;a mixed gas separator including an adsorbent that adsorbs the incondensable gas, and a cooler; anda vacuum exhauster;said method comprising:a first step of introducing the mixed gas highly compressed by said compressor into said mixed gas separator;a second step of liquefying and recovering the condensable gas by cooling said mixed gas separator with said cooler while said adsorbent adsorbs the incondensable gas contained in the mixed gas in a high pressure state; anda third step of exhausting the incondensable gas from said adsorbent in a low pressure state where the gas in the mixed gas separator has been exhausted by said vacuum exhauster.
