HYDROCARBON RESIDUE UPGRADATION PROCESS

摘要

The present subject matter provides a process for hydrocarbon residue upgradation. The combination of the hydrocarbon residue along with aromatic rich hydrocarbons, catalysts and surfactants allow the operation of visbreaking unit at higher temperature while producing a stable bottom product.

1. A process for hydrocarbon residue upgradation, the process comprising:
(a) mixing hydrocarbon residue with aromatic rich hydrocarbon to obtain a first mixture; (b) contacting the first mixture with a combination of a oil soluble catalyst and a surfactant to obtain a second mixture; (c) heating the second mixture in a furnace at a temperature range of 400-500° C. for a residence time of 1-5 min; (d) treating effluent from the furnace with aromatic rich hydrocarbon and the surfactant to form a third mixture; (e) adding an aqueous solution of a water soluble catalyst to the third mixture to obtain a fourth mixture; (f) subjecting the fourth mixture in a soaking vessel to a pressure in the range of 4-30 kg/cm2 at a temperature in the range of 400-480° C. and a residence time in the range of 10-50 min; and (g) passing effluent from the soaking vessel to fractionating column followed by visbreaking vapour recovery section to obtain gas, naphtha, gas oil, visbroken tar, and sour water
