PETROLEUM NEEDLE COKE PLANT Russian patent published in 2022 - IPC C10B55/00 B01J19/00 

FIELD: oil refining.

SUBSTANCE: invention relates to the field of oil refining, in particular to a plant for the production of petroleum needle coke. The proposed plant includes a feedstock heating furnace, a light feedstock evaporator, heat exchange equipment, a light feedstock separator, a thermocondensation reactor, a distillation column, a secondary feedstock heating furnace, and coking chambers. In the unit, the feedstock feed line is sent through the feedstock heating furnace to the evaporator, where the feedstock is separated into light and heavy streams, while the heavy stream is sent to the distillation column through the feedstock heating furnace, and the light component, mixing with recirculating middle distillates from the distillation column after the removal of the gas fraction in the light feedstock separator, it is sent through the feedstock heating furnace to the thermal condensation reactor. In the thermal condensation reactor, it is maintained at a temperature of 500-570°C and a pressure of 0.9 to 2.5 MPa, after which it is sent to a distillation column, from the cube of which the secondary raw material is sent for coking through the secondary raw material heating furnace to the coke chambers, which operate in turn. Wherein, coking gas oil is returned to the distillation column, from which gasoline fraction vapors and gaseous products are removed, and middle distillates are sent for recycling.

EFFECT: creation of a simplified installation for the production of needle coke.
