INSTALLATION FOR CAPTURE OF GAS EMISSIONS Russian patent published in 2021 - IPC B01D19/00 B65D90/28 F17C13/12 F17D1/75 

FIELD: oil and gas, petrochemical and oil refining industries.

SUBSTANCE: invention relates to the oil and gas, petrochemical and oil refining industries, in particular to the collection, preparation, storage and transportation of well products, oil, oil products and volatile liquids, including at oil and water treatment facilities remote from gas collection systems. The installation for capturing gas emissions includes two tanks connected by a gas equalizing piping connected to the vapor volumes of the tanks through flame arresters, a gas pipeline connecting the gas equalizing piping to a condensate collector, a gas pipeline connecting the gas control point with control valves and a pressure sensor. The outlet line of the condensate trap is connected to the flare. Between the condensate trap and the gas pipelines connecting with the steam spaces of the tanks, a gate valve platform is installed, including electric valves installed on each gas pipeline connecting the gas equalization piping to the steam volumes of the tanks, and two control valves connecting the gas equalizing piping to the gas control point and the condensate collector. Pressure sensors are installed on the gas pipeline before and after the first control valve. The condensate trap is additionally connected by a gas pipeline to the buffer tank and to the annular space of the wells.

EFFECT: invention provides the creation of an installation for capturing gas emissions that is simple and effective in operation at oil and water treatment facilities containing hydrogen sulfide, remote from gas collection systems. The invention provides continuous regulated work of collection and removal of gas emissions, eliminating the loss of time for the actuation of control valves and pollution of the air basin with harmful emissions. The invention allows reducing in operating and material costs associated with the construction, maintenance of the device, the consumption of electricity at the treatment plant for the preparation of high-viscosity sulphurous oil.
