GAS ODORANT AUTOMATIC SUPPLY INTO PIPELINE METHOD AND EQUIPMENT FOR ITS REALISATION Russian patent published in 2010 - IPC F17D3/12 

FIELD: oil-and-gas industry.

SUBSTANCE: method and equipment assigned for chemical reagent dosed supply into transported natural gas. According to the method empty a measuring storage into gas pipeline by gradually supplying gas from gas measuring storage. Equipment contains a tank with a liquid, connected hydraulically to the measuring storage with level sensor, gas reducer, controlling equipment, and connecting them main pipes, also connected to the gas pipeline with pressure controlling element, dividing it for high and low pressure gas pipelines, with installed in the low pressure gas line gas consumption measurement block, at that the high pressure gas line connected with the gas reducer via first main pipeline, and the low pressure gas line connected with the tank upper point via the second main pipeline and with the second hydraulic line to measuring storage lower point, at that the measuring storage top point located above the tank top point and connected to it via third main pipeline, thus innovation is in that equipment equipped with gas gradual supply storage and the control block, the control equipment executed with as a normally open valves and normally closed valves with a drive.

EFFECT: operation reliability increase and widen application area.
