Abstract
A gas separation system, comprising a buffer tank that stores therein a source gas and supplies the source gas; a pressurizing unit configured to receive the source gas from the buffer tank and pressurize the received source gas; a first refining unit configured to produce a first refined gas by refining the source gas pressurized by the pressurizing unit, and discharge a first waste gas; a second refining unit configured to produce a second refined gas by refining the first refined gas, and discharge a second waste gas; a third refining unit configured to produce a third refined gas by refining the first waste gas; a first collection line configured to guide the second waste gas to the buffer tank, and including a second flow rate control valve for controlling a flow rate of the second waste gas.
