Title:
METHOD TO OBTAIN GAS WITH DIFFERENT COMPONENT IN COLD LIQUEFIED GAS STORAGE TANK
Document Type and Number:
Japanese Patent JPS6057097
Kind Code:
A
Abstract:
PURPOSE:To obtain gas with different component in a liquefied gas storage tank by applying heat to gas from outside by incorporating a heat exchanger in a cold liquefied gas storage tank, evaporating only the component of high specific volatility, and introducing it outside the tank. CONSTITUTION:Heat medium which is heated in an outer heat exchanger 7 proceeds to a heat-exchanger 5 in a tank 1 through a circulating line 6, and here it applies heat to LNG in the tank and only the high volatility component in the LNG is evaporated in the upper space in the tank. The evaporated gas is introduced outside the tank through an evaporating gas line 9, and it is boosted by a compressor 10 and sent to the destination. The outer beat exchanger 7 performs supplying of heat toward a heat medium of the circulating line 6 by a heat supplying medium circulating line 8.
