Anti-foaming pipe and compressor system

A plate-type heat exchanger includes a first heat exchange section and a second heat exchange section that includes a refrigerant flow path independent of the first heat exchange section. Each of the first and second heat exchange sections includes a fixed support supporting heat transfer plates from one end side in an arrangement direction, and a moving support supporting the heat transfer plates at a first support position on the other end side of the arrangement direction. The moving support is moved from the first support position to a retracted position separated in the arrangement direction to form a first removal region between the first support position and a second retracted position, and the heat transfer plates are removed through the first removal region. The first removal region and the second removal region of the second heat exchange section are overlapped with each other.

Dual plate-type heat exchanger with removable plates

A filter with an integrated heater takes in a portion of a fluid of a rotary machine or an external fluid and generates a seal gas that seals the fluid in the rotary machine. The filter with an integrated heater includes: a casing that includes suction port and an ejection port; a filter main body disposed in the casing; and a heater disposed between the filter main body and the ejection port in the casing. The suction port takes in the portion of the fluid or the external fluid from the rotary machine, the ejection port ejects the fluid or the external fluid, and fluid or the external fluid from the suction port passes through the filter main body.

Filter with integrated heater, and rotary machine system

A rotary machine system includes: a rotary machine including a gas seal portion; a gas seal device connected to the rotary machine and that supplies a seal gas to the gas seal portion; and a connecting pipe that connects the gas seal portion and the gas seal device. The rotary machine includes a casing through which a working fluid flows; a rotatable rotary shaft; and the gas seal portion that seals the working fluid by the seal gas having a pressure higher than a pressure of the working fluid in the casing. The gas seal device includes: a seal gas supply pipe through which the seal gas delivered to the connecting pipe flows; a pressure regulating valve provided in the seal gas supply pipe and that adjusts the pressure of the seal gas supplied to the gas seal portion; and a control part.

Rotary machine system

A rotary machine system includes: a rotary machine including a gas seal portion; a gas seal device connected to the rotary machine and that supplies a seal gas to the gas seal portion; a pressure sensor that detects a pressure of the seal gas; a vent portion that discharges the seal gas discharged from the gas seal portion; and a vent pressure sensor that detects a pressure in the vent portion. The rotary machine includes: a casing through which a working fluid flows; a rotatable rotary shaft that passes; and the gas seal portion provided between the casing and the rotary shaft and that seals the working fluid by the seal gas having a pressure higher than a pressure of the working fluid in the casing. The gas seal device includes: a pressure regulating valve; and a control part that controls the pressure regulating valve.

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.
