Definitions
- the present invention relates to a gas separation method.
- the above PSA method has been applied in various fields, but it is often used as a method of producing high-concentration gas by adsorbing one component contained in the raw material gas.
- the PSA method includes a pressurization method that uses a pressure difference of "pressurization - normal pressure” and a suction method that uses a pressure difference of "normal pressure (or slightly pressurized) - reduced pressure”. Also called Swing Adsorption).
- CCU Carbon dioxide Capture and Utilization
- the gas utilization facility is a methane synthesis reactor
- the produced methane has a reducing action on oxides such as iron ore, so it can be used as a reducing agent in a reduction furnace.
- the raw material gas of the methane synthesis reactor is CO 2
- the methane synthesis reaction is an exothermic reaction
- the reaction heat of the methane synthesis can be effectively utilized by using the generated high-temperature methane as it is as a reducing agent in the reduction furnace.
