Title: METHOD FOR SEPARATING CARBON DIOXIDE AND APPARATUS FOR SEPARATING CARBON DIOXIDE
Abstract:
The objective of the present invention is to provide a method for separating carbon dioxide from a mixed gas with use of membrane separation, said method being a technique for efficiently separating carbon dioxide. The above-described objective is achieved by a method for separating carbon dioxide from a mixed gas by supplying the mixed gas to a separation membrane module, wherein the mixed gas is supplied to the separation membrane module at a high linear velocity for the purpose of sufficiently mixing the mixed gas near the membrane.
