The present invention relates to a method for oil gasification. In particular, the present invention relates to a method for oil gasification while reducing wastewater and costly purification systems. The method comprises providing feedstock and water to an oil gasification system; receiving flash gas from the oil gasification system at a flash gas condensing section; extracting vapor generated by the flash gas condensing section; returning water produced by the extracting step to the flash gas condensing section; outputting dry flash gas produced by the extracting step; receiving spent wash water at a syngas cooling section from a syngas washing section; and outputting washed syngas from the syngas washing section.

The present invention provides a process whereby a high viscosity hydrocarbonaceous material is fed to a gasifier for conversion to synthesis gas. The feedstock, steam, oxygen, and recycled gasification system water are all fed into the gasifier through a four stream feed injector. The feedstock in this design is sandwiched between two oxygen streams so as to provide better conversion for the exceptionally heavy feed. The fourth stream down the central bayonet of the feed injector provides the flow path for the recycled water.

In a fluid catalytic cracking (FCC) process riser reactor effluent is rapidly separated into spent catalyst and hydrocarbon product. The separated hydrocarbon product is immediately quenched to an unreactive temperature in the absence of quenching spent catalyst. An increase in debutanized naphtha yield is achieved. By avoiding catalyst quenching, heat duty is saved in the catalyst regenerator.

A process for producing high purity hydrogen is disclosed. Specifically, the process includes (1) partially oxidizing a refinery offgas feedstock to produce a synthesis gas mixture of carbon monoxide and hydrogen, (2) reacting the synthesis gas mixture with steam to convert the carbon monoxide into a raw gas mixture which primarily includes carbon dioxide and hydrogen, and (3) purifying the raw gas mixture to produce high purity hydrogen and a reject gas mixture of impurities. In a preferred embodiment, the purification step occurs in a pressure swing adsorption unit. Alternative embodiments are also described, each of which essentially involve the optional treatment and/or use of the reject gas mixture of impurities.

Methods for grinding hot coke including feeding the hot coke into a system while maintaining the system under less than atmospheric pressure, wetting the coke during the feeding step to assure constant flow of the coke into a grinding mill where the coke is reduced to a slurry and forwarded to a holding tank. Recovering and treating vapors derived from the grinding of the coke and finally feeding the slurry to a gasifier means.

The invention is a method for mixing feedstock with fluidized catalyst in a fluid catalytic cracking (FCC) riser reactor. A dispersed catalyst suspension is passed upwardly at a velocity of 0. 5 to 4 ft/sec. Atomized feedstock is injected downwardly at a velocity of -30 to -1000 ft. /sec to produce a turbulently mixed reaction suspension. Vaporizing feedstock rapidly accelerates the reaction suspension in approximately plug flow. The slip factor between catalyst and hydrocarbon in the reaction suspension defining the departure from ideal plug flow is thereby reduced.
