濃縮された目的ガスの製造方法
Document Type and Number:
Japanese Patent JP6905508
Kind Code:
B2
Abstract:
A method is disclosed for manufacturing a product gas that is a target gas that was concentrated from a mixed gas containing the target gas and an unnecessary gas by the pressure swing adsorption method. This method includes: a step 1 to supply a mixed gas to an adsorption tower (10A) and discharge gas from an adsorption tower (10B), and to have both adsorption towers communicate with each other; a step 2 to discharge gas from the adsorption tower (10A) and supply the mixed gas to the adsorption tower (10B), and to have both adsorption towers communicate with each other; a step 3 to discharge gas from the adsorption tower 10A and supply the mixed gas to the adsorption tower 10B, and to recover a product gas from the adsorption tower 10B; a step 4 to supply the mixed gas to the adsorption tower 10B and discharge gas from the adsorption tower 10A, and to have both adsorption towers communicate with each other; a step 5 to discharge gas from the adsorption tower 10B and supply the mixed gas to the adsorption tower 10A, and to have both adsorption towers communicate with each other; and a step 6 to discharge gas from the adsorption tower 10B and supply the mixed gas to the adsorption tower 10A, and to recover the product gas from the adsorption tower 10A.
