DOWNHOLE REACTOR FOR OXIDATION OF LIGHT HYDROCARBONS Russian patent published in 2013 - IPC E21B43/24 

Abstract RU 2490441 C1

FIELD: oil and gas industry.

SUBSTANCE: downhole reactor for oxidation contains one input for oxidiser delivery through tubing joint and the other input for delivery of light hydrocarbons through a separate pipeline, a mixer, oxidation reactor and a downhole heater. The cup-type mixer is located in the upper part of the downhole reactor. The mixer is equipped with a tube in the centre for premixing of input products and input to feed light hydrocarbons; the mixer is connected to a hydraulic flange connected, in its turn, to the downhole heater by couplings. The oxidation reactor is placed inside the downhole heater. The downhole heater consists of a series of electric heaters hearted by overflow gates fixed to heat sensor casings; in the lower part the heater contains a filter; it is also equipped with a plug with a hole in order to output a derived product.

EFFECT: high yield of reaction product, possibility of permanent temperature control and maintenance inside the reactor and repeated start-up without repeated preparation of the reactor at the surface.
