COMPLEX AUTOMATION SYSTEM OF HYDRAT FORMATION IHYBITOR DISTRIBUTION AND DOSAGE Russian patent published in 2009 - IPC E21B34/16 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production meant for control of inhibitor supply into natural gas streams, for prevention hydraling process in it. The system consists of pump with drive, pressure collector, pipeline for inhibitor withdrawal from collector, pressure stabilisation independent loops, one of which formed with pressure control instrument in pressure collector, its outlet connected with frequency transformer automatic controller, which its outlet connected with pump drive. The second stabilisation loop forms direct action pressure control block, included in group of withdrawal devices between pressure collector and production devices.

EFFECT: broadening of inhibitor streams control system functionality, supplied through independently controlled canals in every point.
