摘要:
Disclosed is a method for enriching combustible gas, which suppresses the deterioration and pulverization of an adsorbent without extending a period for pressure equalization. The pressure equalization is effected by opening a pressure equalization passage opening/closing valve incorporated in a pressure equalization passage, after completion of adsorption in a first adsorption tower and after completion of desorption in a second adsorption tower connected to the first adsorption tower via the pressure equalization passage.
