Provided is a method for removing COcomprising: supplying a gas to be processed containing CO, Nand Oto a feed side of a CO/Oselective permeation membrane within a temperature range of 15&#xb0; C. to 50&#xb0; C.; generating water vapor and supplying the water vapor to the CO/Oselective permeation membrane; selectively removing COfrom the gas to be processed by permeating COin the gas to be processed from the feed side to a permeate side of the COselective permeation membrane selectively to Oand Nin the gas to be processed; and using a COfacilitated transport membrane having CO/Oselectivity and CO/Nselectivity within the temperature range as the COselective permeation membrane, the COfacilitated transport membrane being configured with a hydrophilic polymer containing an amino acid and a deprotonating agent for preventing protonation of an amino group of the amino acid supported by a porous membrane, wherein a COconcentration in the gas to be processed is 3 mol % or less on a dry basis.

Method and apparatus for removing CO2

A system for producing an oxygenate, comprising: a desulfurization apparatus for contacting a raw material gas comprising hydrogen and carbon monoxide with a desulfurizing agent comprising copper; and a synthesis apparatus for contacting the raw material gas treated by the desulfurizing apparatus with an oxygenate-synthesis catalyst comprising rhodium.
