Abstract:
A Flexicoking™ unit which retains the capability of converting heavy oil feeds to lower boiling liquid hydrocarbon products while making a fuel gas from rejected coke to provide only a minimal coke yield. The heater section of the conventional three section unit (reactor, heater, gasifier) is eliminated and all or a portion of the cold coke from the reactor is passed directly to the gasifier which is modified by the installation of separators to remove coke particles from the product gas which is taken out of the gasifier for ultization. In one embodiment, a portion of cold coke is transferred directly from the reactor to the gasifier, and another portion of cold coke is combined with hot, partly gasified coke particles transferred directly from the gasifier to the reactor. The hot coke from the gasifier is passed directly to the coking zone of the reactor to supply heat to support the endothermic cracking reactions and supply seed nuclei for the formation of coke in the reactor. Coke is withdrawn from the gasifier to remove excess coke and to purge the system of metals and ash.

Claim (Index 9):
A fluid coking unit for converting a heavy hydrocarbon feedstock to lower boiling products and for producing a fuel gas product in a fluid coking process unit comprised of a fluid coking reactor section and a gasifier section, comprising:\n (i) a fluid coking reactor section with an inlet for a heavy hydrocarbon feedstock, an outlet for cracked hydrocarbon vapors at the top of the reactor, an inlet at the bottom of the reactor for a fluidizing gas, an inlet for heated solid particles and a solid particle outlet at the bottom of the reactor for solid particles with coke deposited on them forming cold coke, (ii) a gasifier section with an inlet for steam and oxygen-containing gas at its bottom, a solid particle inlet for the cold coke, an outlet for fuel gas at its top and a solid particle outlet for solid particles heated in the gasifier forming hot coke, (iii) a transfer line for passing the hot coke from the solid particle outlet of the gasifier section to the solid particle inlet of the reactor section for recycling the hot coke from the gasifier section to the reactor section to supply heat to the coking zone of the reactor, and (iv) a transfer line for passing (a) a first portion of the cold coke from the reactor solid particle outlet directly to the solid particle inlet of the gasifier section, and (b) a second portion of the cold coke from the reactor solid particle outlet to be combined with the hot coke in the transfer line for passing the hot coke to the solid particle inlet of the reactor section.
