<p>PURPOSE:To eliminate heat regulation of liquefied gas and use of BOG (evaporated gas) temperature raising device in the heat regulation and delivery method of BOG. CONSTITUTION:A BOG delivery line 2 is branched by a BOG branch line 13 to supply a part of BOG to a LNG delivery line 9. A flow rate of LPG for heat regulation is feed-forward controlled by a flow rate and quantity of heat of LNG and BOG, and final minute adjustment of the quantity of heat is feedback controlled by heat quantity of gas. Heat regulation of liquefied gas and a temperature raising device can be eliminated because control of heat quantity and raising temperature of BOG are unnecessary. Consequently, it is possible to reduce the cost of facility.</p> |
