REAGENT DOSING METHOD AND EQUIPMENT FOR IMPLEMENTATION Russian patent published in 2010 - IPC C10G33/04 G05D27/00 

FIELD: oil-and-gas industry.

SUBSTANCE: group of inventions related to oil industry, to dosing methods and equipment of reagents, such as demulsifying agents and corrosion inhibitors - oil development and preparation at fields and can be used at oil treatment and water preliminary discharge plants. Preliminary equalise pressure in a reagent tank and accompanying oil gas pipeline. Then regulate reagent flow rate, compare measured with flow metre reagent flow rate value in regulator with reagent flow rate target value, and according hose values difference create a control signal to a control valve, installed on pipe connecting nozzle to the tank. Device contains sealed tank with reagent, located over the pipeline top generating line. A section of a smaller diametre with nozzle mounted into the pipeline. The nozzle connected to the tank via pipeline, with reagent flow metre, connected to the regulator, reagent target flow rate signal transferred to the second end it, and outlet connected with control valve, installed on the pipe connecting nozzle to the tank. The reagent tank connected to the accompanying oil gas pipeline with equaliszing line.

EFFECT: simplification of reagent dosing into the pipeline, metal and power consumption decrease, ensuring reagent intense mixing with a total volume of pumped media.
