DEVICE FOR GASLIFT TRANSPORTATION Russian patent published in 2017 - IPC F04F1/20 

FIELD: transportation.

SUBSTANCE: device contains the lifting pipe, which has been lowered into the liquid upto the hydraulic fluid intake place and brought out upper the liquid surface. The pipe consists of the lower pipeline (2), the upper pipeline (1) and the submerged container (3) into the liquid with the internal placement of the pipeline (1) lower cut in its bottom part, and the pipeline (2) upper cut - in its upper part. The device includes the gas supply pipe (5) with compressed gas. The pipe (5) is connected to the container (3), forming the gas cavity in the upper part of the pipeline (2). The container (3) can be submerged in the liquid in the depth change range: from the maximum value at which the pipeline (1) height does not exceed the comparable with lifting pipe immersion height the liquid layer height over the lower boundary of the gas cavity in the pipeline (2), upto the minimum height, estimated from the pipeline (1) height, the part determined by the ratio of the cross-sectional areas of this pipeline (1) and the container (3).

EFFECT: invention makes possible to reduce the depth of the compressed gas injection by more than two times with the slight increase in the flow characteristic, which makes it possible to use low-pressure injection machines instead of high-pressure ones, to reduce the length of gas utilities and to reduce the operation costs for its maintenance.
