<p>PURPOSE:To enhance the energy-saving effect by delivering low temperature liquefied gas obtained by compression, condensation and liquefaction and supplied into a gas condenser by heating it with a heat exchanger. CONSTITUTION:When low temperature liquefied gas is delivered, a stop valve 8 at the lower part of a gas condenser 4 and a stop valve 26 at the upper part of a gas purger 14 are closed, a pressure reducing valve 23 is opened, a delivery pump 3 is driven, and low temperature liquefied gas is supplied from a low temperature storage tank 1 to the gas condenser 4. Thus, most of the liquefied gas is stored in the condenser 4 while being sprayed from a conduit 2. Simultaneously, the liquefied gas is partly returned through a conduit 16, the gas purger 14 and a conduit 25 to the tank 1, the gas in the gas purger 14 is liquefied and is stored in the condenser 4, and the liquid level in the condenser 4 is raised. When the liquid level is raised higher than the upper level of the lowest position in the level variation range, the stop valves 8, 26 are opened.</p> |
