SYSTEM FOR GAS SEPARATION

摘要

A gas separation system, comprising a buffer tank (600) that stores therein a source gas and supplies the source gas; a pressurizing unit (400) configured to receive the source gas from the buffer tank (600) and pressurize the received source gas; a first refining unit (100) configured to produce a first refined gas by refining the source gas pressurized by the pressurizing unit (400), and discharge a first waste gas; a second refining unit (200) configured to produce a second refined gas by refining the first refined gas, and discharge a second waste gas; a third refining unit (300) configured to produce a third refined gas by refining the first waste gas; a first collection line (710) configured to guide the second waste gas to the buffer tank (600), and including a second flow rate control valve (932) for controlling a flow rate of the second waste gas; a second collection line (720) configured to guide the third refined gas to the buffer tank (600), and having a first flow rate control valve (931) for controlling a flow rate of the first waste gas; and a control unit (800) configured to control the first flow rate control valve (931) and the second flow rate control valve (932).
