Abstract

PROVIDED IS A METHOD OF ACQUIRING HIGH-PURITY NITROGEN GAS FROM A MIXED GAS OF METHANE AND NITROGEN USING AN INEXPENSIVE PSA APPARATUS AND RECOVERING METHANE FOR POWER GENERATION AT A HIGH RECOVERY RATE. PROVIDED IS A METHOD FOR SEPARATION OF METHANE AND NITROGEN FROM FEED GAS WHICH IS A MIXED GAS MAINLY FORMED OF METHANE AND NITROGEN BY A PRESSURE FLUCTUATION TYPE ADSORPTION METHOD USING TWO OR MORE ADSORPTION TOWERS A AND B, IN WHICH GAS SEPARATION ADSORBENTS 21 AND 22 HAVING AN EQUILIBRIUM ADSORPTION AMOUNT WITH RESPECT TO METHANE WHICH IS GREATER THAN THAT WITH RESPECT TO NITROGEN ARE FILLED IN THE ADSORPTION TOWERS A AND B, THE TIME OF THE PRESSURE EQUALIZATION STEP PERFORMED BY THE ADSORPTION TOWER A AFTER FINISHING THE ABSORPTION STEP AND THE ADSORPTION TOWER B AFTER FINISHING THE REGENERATION STEP IS 25 SECONDS TO 35 SECONDS, METHANE IS OBTAINED AT A CONCENTRATION OF 70% OR MORE AND A RECOVERY RATE OF 95% OR MORE, AND NITROGEN IS RECOVERED AT A CONCENTRATION OF 95% OR MORE.
