MULTIPURPOSE PLANT FOR UTILISATION OF ASSOCIATED GAS AND DRILLING OIL WASTES Russian patent published in 2013 - IPC F23G5/00 

FIELD: oil and gas industry.

SUBSTANCE: multipurpose plant for utilisation of associated gas and drilling oil wastes includes a loading device for supply of drilling oil wastes to a rotating drum, an unloading device for removal of oil sludge processing wastes from the rotating drum, a lined rotating drum having mixing elements and a drive, a burner device, a fan with a stack, a control panel and a switching assembly of flue gas flow direction with a damper. The plant is equipped with a lined cyclone combustion chamber with tangentially supplied channel of associated gas and an air cooling jacket, a fan supplying the air to the cooling jacket, an additional stack with a damper and injecting holes, which is located between the cyclone combustion chamber and the rotating drum, and an air intake, a water vapour condenser and a fan with a stack, which are located in series after the rotating drum and connected to each other. Associated gas channels in the cyclone combustion chamber are provided with tips in the form of atomisers, to which air is supplied from the cooling jacket; burner device is located in the front end part of the cyclone combustion chamber; water vapour condenser is connected to a condensate trap. Flue gas flow direction switching assembly with the damper is located after an additional stack and attaches the cyclone combustion chamber to the rotating drum. The cyclone combustion chamber, the fan for air supply to the air cooling jacket and the additional stack are arranged in a separate container.

EFFECT: improving environmental cleanliness of utilisation of associated gas due to more qualitative and complete combustion of associated gas at high temperatures in a turbulent combustion mode.
