METHOD OF GAS PUMPING FROM REPAIRED SECTION OF GAS LINE Russian patent published in 2010 - IPC F04D25/02 F17D1/02 F04F5/54 F04B41/00 

FIELD: oil-and-gas production.

SUBSTANCE: for implementation of method of gas pumping from disconnected section of gas line (3) is fed into nozzle of one or group of ejectors (9) and it is implemented exhaust of gas. During pressured decrease at pumped section it is installed additional boosting device (21) and it is implemented pumping process. Additionally in the capacity of working body it is used natural gas, and in the capacity of energy it is used potential energy of difference of gas before closed crane (4) of disconnected section (3) and gas pressure in low-head chamber of ejector (9). If required rate of pumping is not achieved, into work it is introduced first stage compressor (17).

EFFECT: implementation of total pumping of gas from disconnected section of gas line into working per minimal able by technological conditions time period without essential of structure and at keeping of its maximal able capacity.
