Abstract

In an integrated coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a scrubbing process and wherein the resulting solids-liquid slurry is stripped with a stripping gas to remove acidic gases, at least a portion of the stripping gas comprises a gas comprising hydrogen, nitrogen and methane separated from the coker products.

Integration of stripping of fines slurry in a coking and gasification process

Patent Degeorge, C W

In an integrated fluid coking and gasification process wherein a stream of fluidized solids is passed from a fluidized bed coking zone to a second fluidized bed and wherein entrained solid fines are recovered by a wet scrubbing process and wherein the resulting solids-liquid slurry is stripped to remove acidic gases , the stripped vapors of the stripping zone are sent to the gas cleanup stage of the gasification product gas. The improved stripping integration is particularly useful in the combination coal liquefaction process, fluid coking of bottoms of the coal liquefaction zone and gasification of the product coke.

Technical Report

Coal is fed with recycled raw gas used as a carrier to the gasification system, consisting of four identical reactors and ancillary equipment. Oxygen from air separation and exhaust steam from steam turbine are also fed to the gasification system. During normal operation only steam flows through the grid of the reactor to create a fluidized bed where gasification of the coal takes place. Flow to the reactor venturi will be a mixture of steam and oxygen with the oxygen concentration limited to a maximum of 21% by volume. The flow to the center jet of the reactor will bemore »« less
Catalytic fluid coking and gasification process

Patent Metrailer, W J

An integrated catalytic fluid coking and gasification process is provided in which a portion of the coke produced in the coker is steam gasified to produce a hydrogen-containing gas and a catalytic partially gasified coke. Subsequently, a portion of the catalytic partially gasified coke is burned to provide heated partially gasified coke which is recycled to the gasification zone. A portion of the catalytic partially gasified coke is passed from the gasification zone to the coker to contact the coker vapor phase product comprising normally liquid hydrocarbons and to crack at least a portion of the normally liquid hydrocarbons.
