    摘要: A gas recovery system separates a mixed gas including a process gas and an inert gas. The gas recovery system includes a cooling section for cooling and liquefying the process gas contained in the mixed gas by cooling the mixed gas at a temperature higher than a condensation temperature of the inert gas and lower than a condensation temperature of the process gas, a separating section for separating the cooled mixed gas into the process gas in a liquid state and the inert gas in a gas state, and a process gas recovery line that is connected to the separating section which circulates and gasifies the liquid-state process gas and then supplies the process gas into the a compressor. The mixed gas is formed by mixing the process gas, which is compressed by the compressor, and the inert gas, which is supplied to a seal portion of the compressor.

    摘要: A plate laminated type heat exchanger includes: a plate laminated body which is formed by laminating a plurality of plates; and a heat exchanger body which includes a first header through which fluid (G) flows in from outside of the plate laminated body and a second header through which the fluid (G) flows out to the outside of the plate laminated body which are connected to the plate laminated body. Each of the plurality of plates is formed from a flat plate shape having a first surface and a second surface. The first surface is provided with a plurality of grooves defined by inner walls through which the fluid flows. The plurality of plates are connected each other so that the first surface of one of the plurality of plates is brazed to the second surface of the other one of the plurality of plates.

    摘要: A compressor system includes a compressor and a supply control unit that controls a state of supply of water and a state of supply of oil. The supply control unit includes a rate-of-change acquisition unit that acquires a rate of change in efficiency of the compressor, a supply amount acquisition unit that acquires the amount of supply of the oil, an operating cost acquisition unit that acquires an operation cost from the rate of change, an oil cost acquisition unit that acquires an oil cost from the amount of supply of the oil, and a cost relationship acquisition unit that acquires a plurality of provisional relationship values that are the relationship between the operating cost and the oil cost under each of the plurality of provisional cleaning conditions.
