。Carbon dioxide is conventionally produced by absorbing and separating crude carbon dioxide raw material gas such as natural gas, fermentation gas, by-product gas from petroleum F#, or by-product gas from the ammonia synthesis process using the MEA method (monoethanolamine method) or the potassium carbonate method. It is done as follows. Recently, a method of producing carbon dioxide gas by converting waste gas from a metal smelting furnace or melting agent into carbon monoxide has also been used.

There is a method of converting carbon dioxide into carbon oxide to produce carbon dioxide, and then absorbing and separating this carbon dioxide using an MEA method or the like.

Among the methods listed above, the method of absorption and separation using the MEA method or the like becomes relatively expensive when the carbon dioxide concentration of the waste gas is low, and the method of performing carbon oxide conversion also requires steam, which increases the cost. Note that these waste gases have a low calorific value and are generally mixed with coke gas or heavy oil and used as fuel for heating ovens and the like.

As a result, carbon dioxide, some hydrogen, carbon oxide, nitrogen gas, etc. in the waste gas permeate through the membrane, and a permeated gas with a high concentration of carbon dioxide is obtained.

Note that the gas from which carbon dioxide has been removed by the membrane separator (1) is stored in the gas tank (2) as a gas with a higher heat generation layer than the raw material waste gas. Then, C1, this gas having a high heat generating layer is used as a substitute for blast furnace gas, mixed with coke gas or heavy oil, and supplied as a fuel for heating, etc.
