Title:
METHOD AND DEVICE FOR DELIVERING LOW TEMPERATURE LIQUEFIED GAS
Document Type and Number:
Japanese Patent JPS5751099
Kind Code:
A
Abstract:
PURPOSE:To improve the safety and the thermal efficiency by intaking evaporated gas to the upper part of a low temperature storage tank for LPG, LNG, ammonia or the like by an ejector, heating it and delivering it as mixed low temperature liquefied gas. CONSTITUTION:A blower 8 is stopped at the delivering time, a delivery pump 3 is driven, low temperature liquefied gas is intaked via a conduit 2 by a delivery pump 3, and is intaked by the pump 3 through the conduit 2 to an ejector 4. The low temperature liquefied gas and low temperature liquefied gas are mixed by the ejector 4, the mixed low temperature liquefied gas is heated to room temperature by a heat exchanger 5, and is then delivered. Thus, the internal pressure in the tank is not raised, and the low temperature liquefied gas is mixed with the gas by the ejector 4 and is raised slightly at its temperature. Accordingly, it can save the quantity of heat for heating it by the heat exchanger 5.
