Abstract
Gas supplying method and system in which effective component gas in exhaust gas can be separated and purified efficiently to be resupplied regardless of variation in the flow rate or composition of the exhaust gas and consumed gas can be replenished efficiently. In a method for collecting exhaust gas discharged from a gas using facility, separating/purifying effective component gas contained in the exhaust gas and supplying the effective component gas thus obtained to the gas using facility, the exhaust gas discharged from the gas using facility is added with a replenishing gas of the same components as the effective component gas before the effective component gas is separated and purified.
Claims5
A method for collecting exhaust gas discharged from a gas using facility, comprising the steps of:
- (1) collecting an exhaust gas discharged from a gas using facility into a gas storage tank, wherein the exhaust gas comprises an effective component gas, and an atmospheric gas or a sealing gas;
- (2) adding a replenishing gas of the same components as the effective component gas to the gas storage tank containing the exhaust gas discharged from the gas using facility, so that the component ratio of the gas to be separated and purified becomes constant;
- (3) separating the effective component gas contained in the exhaust gas from the atmospheric gas or the sealing gas;
- (4) purifying the effective component gas separated by the separating step;
- and
- (5) supplying the effective component gas thus obtained to the gas using facility.
