Method of operating a gas separation apparatus and gas separation equipment

摘要

PROBLEM TO BE SOLVED: To provide a gas separator capable of obtaining a product gas of high concentration immediately after starting of operation.;SOLUTION: The gas separator is made to a pressure variation adsorption system for repeatedly performing at least four steps including the first step provided with at least two adsorption columns T₁, T₂ and a storage tank, pressurizing the adsorption column T₁ and depressurizing the adsorption column T₂; the second step for communicating raw material gas introduction ends of the adsorption columns T₁, T₂ with each other and the product gas leading out ends with each other and making a pressure of the adsorption column T₂ approaching to a pressure of the adsorption column T₁; the third step for pressurizing the adsorption column T₂ and depressurizing the adsorption column T₁; and the fourth step for communicating the raw material gas introduction ends of the adsorption columns T₁, T₂ with each other and the product gas leading out ends with each other and making the pressure of the adsorption column T₁ approach to the pressure of the adsorption column T₂. When a stop signal is inputted, operation is stopped at the time when either of the second step or the fourth step is finished, and when an activation signal is inputted, operation is started from the same time as the time when it is stopped.;COPYRIGHT: (C)2009,JPO&INPIT
