    摘要: Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.

    摘要: The present invention provides a CO shift conversion device and a CO shift conversion method which improves CO conversion rate without increasing usage of a shift conversion catalyst. A CO shift conversion device includes: a CO shift converter 10 having a catalyst layer 5 composed of a CO shift conversion catalyst and performing CO shift conversion process on a gas flowing inside; and a CO 2 remover 51 removing CO 2 contained in a gas introduced. The catalyst layer 5 is composed of a CO shift conversion catalyst having a property that a CO conversion rate decreases with an increase of the concentration of CO 2 contained in a gas flowing inside. The concentration of CO 2 contained in a gas G0 to be processed is lowered by the CO 2 remover 51 and, after that, the resultant gas is supplied to the CO shift converter 10 where it is subjected to the CO shift conversion process.

    摘要: A biogas combustion system that obtains a stable output and saves energy is realized. A combustion system comprises a separation portion 14 that removes carbon dioxide from a treatment target gas containing a mixture gas containing methane as a main component and containing carbon dioxide to obtain methane gas of a high purity in which at least a content of carbon dioxide has been reduced, and a combustion portion 15 that combusts the methane gas. The separation portion 14 includes a first treatment chamber 11 and a second treatment chamber 12 separated from each other by a separation membrane 13 therebetween. The separation membrane 13 selectively allows the carbon dioxide in the treatment target gas supplied to the first treatment chamber 11 to pass therethrough to the second treatment chamber 12 to obtain a first separation gas having a higher methane purity than the treatment target gas in the first treatment chamber 11 and a second separation gas containing the carbon dioxide in the treatment target gas in the second treatment chamber 12.
