Patent ID: 10703631

Abstract:
A neon recovering/purifying system including: a recovery vessel that is arranged on an exhaust gas route and stores exhaust gas, the exhaust gas route being branched and extending from a discharge line; a compressor that increases a pressure of the exhaust gas sent out from the recovery vessel, to a third pressure; an exhaust gas flow rate regulating unit that regulates a flow rate of the exhaust gas whose pressure has been increased by the compressor; a first impurity removing unit that removes a first impurity from the exhaust gas; a second impurity removing unit that removes a second impurity from the exhaust gas from which the first impurity has been removed; a pressure increasing vessel that stores purified gas that has been processed by the first impurity removing unit and the second impurity removing unit; a pressure reducing valve that reduces a pressure of the purified gas sent out from the pressure increasing vessel, to the first pressure; and a purified gas flow rate regulating unit that regulates a flow rate of the purified gas supplied to a supply line of a manufacturing system.
