METHOD AND DEVICE FOR GAS TRANSFER THROUGH ACTING PIPE-LINE Russian patent published in 2000 - IPC

FIELD: pump and compressor engineering, applicable in petroleum, gas and other branches of industry for transfer of liquids and gases. SUBSTANCE: the method comprises the main cycle of gas compression by means of ejection entrainment of gas by a jet of working fluid from the pressure pipe-line, their mixing with formation of a single flow, gas compression in the working chamber of the jet device and separation of the gas-fluid mixture in a separator with return of the working fluid to the receiving pipe-line for fluid, and an additional cycle of gas compression to a pressure sufficient for displacement of gas to the pressure pipe-line for gas, which is accomplished after complete substitution of gas for fluid in the separator at the end of the main cycle by feeding of an additional amount of fluid from the pressure pipe-line for the working fluid to the separator simultaneously with the gas-fluid mixture from the jet device. The device for gas transfer through the acting pipe-line has a jet device with working and receiving chambers and nozzle, separator connected to the outlet of the working chamber, whose gas outlet is connected to the gas pipe-line with a check valve installed on it, working fluid receiving pipe- line with a power pump installed on it, connected through the pressure pipe-line to the cavity of the jet device nozzle, connected to the jet device receiving chamber is the gas receiving pipe-line with a check valve installed on it, and a two-position slide valve with a drive regulator, which is installed at the outlet of the fluid separator, and in one of the working positions connects it through the flow governor to the fluid receiving pipe-line, and in the other - communicates it through another flow governor to the working fluid pressure pipe-line. EFFECT: reduced power intensity of the process of gas transfer due to reduced hydraulic energy loss in the additional gas compression cycle, reduced amount of fluid getting in the gas flow due to continuous separation of the gas-fluid mixture during both cycles of gas compression. 4 cl, 1 dwg
