Abstract
The present invention addresses the problem of providing a technology for efficiently separating carbon dioxide in a method for separating carbon dioxide from a mixed gas by using a membrane separation method. The problem is solved by a method including supplying a mixed gas to a separation membrane module to separate carbon dioxide from the mixed gas, in which the mixed gas is supplied to the separation membrane module at a high linear velocity in order to sufficiently mix a mixed gas in the vicinity of a membrane.
