GAS-DISTRIBUTING STATION Russian patent published in 2019 - IPC F17D1/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to gas engineering, particularly, to gas distribution stations for reduction of gas pressure in gas pipeline. Result is achieved by separation of rust and / or scale in cavities of curvilinear grooves located on inner surface of divergent part of ejector with subsequent accumulation of solid particles in curved groove and their discharge through contaminant collector. Curved grooves have a dovetail profile. Circular groove connected with contaminant removal device is arranged at ejector outlet.

EFFECT: technical task of the proposed invention is to ensure efficient operation of the gas distribution station while maintaining normalized parameters of the degree of purification of natural gas from solid particles of contaminants coming through the ejector to the consumer.
