摘要： An apparatus for producing a liquefied gas using a Rankine cycle is provided. The apparatus includes a first compression means for adiabatically compressing a heat transfer medium; a first heat exchanger for constant pressure heating the adiabatically compressed heat transfer medium; a plurality of parallelly arranged expansion means for adiabatically expanding the heated heat transfer medium; a second heat exchanger for constant pressure cooling the adiabatically expanded heat transfer medium; and a flow passageway for guiding the heat transfer medium that has been guided out from the second heat exchanger to the first compression means.

摘要： An apparatus and a method for supplying a liquid fuel gas with little fluctuation in the heat generation amount of the fuel gas by controlling the Wobbe index of the fuel gas supplied to combustion equipment quickly and stably even when the composition of the supplied fuel gas fluctuates, comprises a liquid source material supplying portion (10) having a storage tank (11), a supply amount adjusting means (12) and a specific gravity measuring means (13); an adjustment fluid supplying portion (20) having a storage tank (21) and a supply amount adjusting means (22); and a mixing portion (30) having a mixing tank (31) in which the liquid source material is mixed with the adjustment fluid and a supply-out portion (32) from which the mixed liquid fuel gas is supplied out, wherein the liquid source material in a low-temperature liquid state is mixed with the adjustment fluid in the mixing tank (31), and the supply amount of the adjustment liquid corresponding to the supply amount of the liquid source material is adjusted by feedforward control using, as an index, a measured value of the specific gravity of the liquid source material so that a Wobbe index of the mixed liquid fuel gas falls within a predetermined value range.
