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.

摘要： In order to provide a technique for enriching a combustible gas that allows enrichment of the combustible gas to a higher concentration in an efficient manner with minimization of loss of a source material, there are provided an adsorption tower charged with an adsorbent, a feeding/discharging means for feeding a source gas containing a combustible gas and air, a collecting means for desorbing the combustible gas adsorbed to the adsorbent and collecting the desorbed gas, a controlling means for sequentially effecting a combustible gas adsorption process and a combustible gas desorption process, a detecting means for detecting the concentration of the combustible gas in the source gas, and an operation condition setting section for varying an adsorption completion timing for the controlling means to complete the adsorption process, based on the combustible gas concentration detected by the detecting means.

摘要： A combustible gas enrichment system includes an adsorption unit charged therein with an adsorbent for selectively adsorbing a combustible gas, a source gas feeding means capable of feeding source gas containing the combustible gas into the adsorption unit from the outside, a suctioning means capable of suctioning the gas from the inside of the adsorption unit and a controlling means for executing an adsorption process for feeding the source gas into the adsorption unit for adsorption of the combustible gas to the adsorbent and a desorption process for desorbing the combustible gas from the adsorbent under the suction force of the suctioning means after the adsorption process and taking the desorbed combustible gas to the outside. The controlling means operates the suctioning means such that the suction force of the suctioning means when no desorption process is effected is smaller than the suction force when the desorption process is effected.
