<p>PURPOSE:To dispense liquefied gas with calorie adjustment, by controlling the composition of gas at the final outlet port of equipment so that the composition is equal to that of liquefied gas supplied first. CONSTITUTION:A heavy portion, which is separated by a gas/liquid separator and is not yet evaporated, is conducted from the liquid phase part of the separator to a liquid contact unit 14 through a pipe 17 while the flow rate of the heavy portion is regulated by a flow control mechanism 13. In the liquid contact unit 14, the heavy portion comes into direct contact with superheated evaporated gas from a pipe 18. The flow rate of the heavy portion flowing out of the liquid phase part of the gas/liquid separator 11 and not yet evaporated is regulated by the flow control mechanism so that the composition of gas at the final outlet port of equipment is made equal to that of liquefied gas supplied first. According to this constitution, a calorific value is made constant and calorie adjustment is not needed.</p> |
