GAS ACCUMULATION REMOVAL, DEGASIFICATION, AND RESERVOIR RELEASE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device that, in removing gas accumulated in a pipeline or a tank and equipment coupled to the pipeline, and in discharging or separating removal gas, is capable of removing the accumulated gas, degasifying fluid and releasing a reservoir, without draining the fluid to the outside of a system, and without causing pressure loss of the force-feed fluid, by using the same device.;SOLUTION: In means for discharging or separating gas and dissolved gas (removal gas) without draining fluid in a system, a ventilation layer is arranged inside a pipe body (a pressure wall), and further, a separation membrane is arranged therein. In the means, prevention of gas accumulation and simultaneous discharge or separation of removal gas, and reservoir release, are carried out according to means for vacuum drawing the ventilation layer.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2019,JPO&INPIT
