PLANT FOR COKING OF OIL RESIDUES Russian patent published in 2017 - IPC C10B55/00 

FIELD: oil and gas industry.

SUBSTANCE: plant for coking of oil residues includes the reactors 6 with secondary feed lines from the tube furnace 1 and the output of steam-gas coking products, and the distillation column equipped with lines for withdrawing the distillate coking products and secondary raw materials. The convective 2 coil of the furnace 1 is designed to heat the feedstock and is communicated with the lower part of the distillation column. The radiant 3 coil of the furnace 1 is designed to heat secondary raw materials and is communicated with the bottoms of the distillation column. The line for the recovery of steam-gas coking products is connected with the rectification column, and at least two pressure regulators 7 and 8 are installed on it, equipped with the stop valves 9 and 10.

EFFECT: simplifying the plant scheme due to excluding the separator and sedimentation tanks from it, while maintaining the necessary pressure in the rectification column while maintaining the plant overhaul run.
