Abstract: The invention relates to a thermal conversion process for continuously producing hydrocarbon vapor and continuously removing a free-flowing coke. The coke, such as a shot coke, can be withdrawn continuously via, e.g., a staged lock hopper system.

Abstract: This invention relates to a process for controlling coke morphology and. foaming in delayed coking. More particularly, acoustic energy is used to control coke morphology and foaming in a delayed coking process.

Abstract: A method for upgrading heavy oils by contacting the heavy oil with an inhibitor additive and then thermally treating the inhibitor additized heavy oil. The invention also relates to the upgraded product from the inhibitor enhanced thermal treatment process.

Abstract: A modified vacuum distillation and delayed coking process for making substantially free-flowing coke, preferably free-flowing shot coke. A vacuum resid feedstock is used which contains less than about 10 wt. % material boiling between 900° F. and 1040° F. as determined by HTSD (High-temperature Simulated Distillation). The use of such a high boiling resid favors the formation of shot coke instead of sponge or transition coke. The distillate recycle reduces coker furnace fouling potential of the heavier feedstock.

Abstract: A method of blending delayed coker feedstocks to produce a coke that is easier to remove from a coker drum. A first feedstock is selected having less than about 250 wppm dispersed metals content and greater than about 5.24 API gravity. A second delayed coker feedstock is blended with said first resid feedstock so that the total dispersed metals content of the blend will be greater than about 250 wppm and the API gravity will be less than about 5.24.

Abstract: A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. A low molecular weight additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.

Abstract: A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. An overbased alkaline earth metal detergent additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.

Abstract: A method for producing and removing coke which has bulk morphology such that at least about 30 volume percent is free-flowing under the force of gravity or hydrostatic forces from a delayed coker drum. At the completion of the fill cycle, the coker drum, filled with hot coke, is cooled by steaming and then flooding it with water, thereby producing a coke/water mixture. The coke/water mixture is released from the coke drum through one or more drum closure/discharge throttling systems near the bottom of the coker drum.
