Purification system

Abstract

A purification system has: a supply section that is provided in a line where a to-be-purified gas containing methane and oxygen flows, and supplies ozone to the to-be-purified gas by generating the ozone from the oxygen contained in the gas; a compressing section that is provided downstream of the supply section in the line, and adiabatically compresses the to-be-purified gas supplied with the ozone; and a catalyst that is provided downstream of the compressing section in the line, and purifies the methane in the to-be-purified gas under an ozone atmosphere, in which the compressing section raises temperature of the to-be-purified gas by adiabatically compressing the to-be-purified gas.
