PUMPING METHOD OF HYDROCARBON LIQUID VIA PIPELINE WITH PUMPING STATION WITH INTRODUCTION OF ANTI-TURBULENT ADDITIVE TO PIPELINE Russian patent published in 2013 - IPC F17D1/16 

FIELD: machine building.

SUBSTANCE: method involves introduction of anti-turbulent additive to inner cavity of linear section of the pipeline. The additive is introduced to supply pipeline at the inlet of the pumping station in the piece with length L=(τ_dilution-τ_PS)·v to the inlet of the pumps, where τ_dilution - time of the additive dilution in the pumped product, v - speed of pumped liquid after the additive introduction points, τ_PS=V_PS/G - residence time of the additive in the volume of hydraulic system V_PS from pumps to the last risk point of additive destruction, and G - volumetric flow rate of the pumped product.

EFFECT: possibility of simultaneous exclusion of the additive destruction at the pumping station points when anti-turbulent additive is being introduced to the pipes cavity with low pressure.
