METHOD FOR LAYING A PIPELINE IN THE GROUND, PUMPING CARBONATED LIQUID Russian patent published in 2022 - IPC F16L1/28 

FIELD: pipeline transport.

SUBSTANCE: invention relates to pipeline transport, and in particular to methods for laying pipelines for pumping carbonated liquids. The method includes laying a pipeline between pumping equipment and a collection point or a booster pump, identifying sections of the pipeline with local rises, equipping these sections with separators to separate gas from liquid. Depending on the gassing of the pumped liquid and the pressure created by the pumping equipment, sections are determined - transition points in which the pressure decreases below the saturation pressure of the gas in the liquid. Separators are installed in sections of the pipeline with local rises following the crossing points. Separators are made in the form of gas locks, connected with the inlet to the upper point of the pipeline section with local rises, and the outlet - with a gas collection tank installed on the surface.

EFFECT: method makes it possible to expand the functionality due to the possibility of laying it in sections that do not contain more than one pipeline line, to simplify the laying by eliminating additional parallel gas pipelines and gas separators.
