Abstract:
An integrated fluid coking/paraffin dehydrogenation process. The fluid coking unit is comprised of a fluid coker reactor and a heater with hot solids recycling between the coker reactor and the heater. A light paraffin stream is introduced into the line wherein the hot particles are recycled to the coking zone. The hot particles act to catalyze the dehydrogenation of the paraffins to olefins.
Abstract:
A fluid coking-gasification process for converting heavy hydrocarbonaceous chargestocks to lower boiling products in which an inorganic metal composition is used to mitigate slagging in the gasifier, wherein the metal is selected from the alkaline-earths, the rare earths, and zirconium. The inorganic metal composition is added either directly into the gasifier or it is mixed with the coke passing from the heating zone to the gasification zone.
Abstract:
Method to improve mixing water-and charge in a hydrocarbon conversion unit comprising foaming the charge with a foaming agent e.g. selected from the group consisting of sulfonates or polymer resins (preferably some oil soluble, some water soluble).
Abstract:
A method for producing a distillable hydrocarbonaceous stream and carbonaceous agglomerates from a heavy crude oil by charging the crude oil and finely divided carbonaceous solids to a rotary kiln with the crude oil and carbonaceous solids being charged in a weight ratio from about 0.6 to about 1.5; tumbling the crude oil and finely divided carbonaceous solids in the rotary kiln at a temperature from about 850.degree. to about 1000.degree. F. for up to about 30 minutes to produce a vaporous stream and agglomerate particles containing a residual portion of the crude oil and finely divided carbonaceous solids; separating the agglomerate particles into a product portion of a desired particle size range and a recycle portion; grinding the recycle portion to produce the finely divided carbonaceous solids and heating the finely divided carbonaceous solids prior to recycling the carbonaceous solids to mixture with the crude oil.
Abstract:
Unsaturated light hydrocarbons are produced by coking a heavy hydrocarbonaceous oil in a conventional fluid coking zone and subsequently heating the vaporous coker product to a higher temperature in a gas-solids separation zone, such as the coking reactor's cyclone separator, with hot solids derived from a coke gasification zone.
Abstract:
Disclosed is a method for generating steam from water containing high concentrations of particulate matter such as silt, clay, etc., without the need for filtering and otherwise treating the water prior to generation of steam therefrom, especially useful for use in a viscous oil recovery process. The method comprises introducing solid particulate materials such as coarse sand, etc., into a thermal cracking unit such as, for example, that is used in the Lurgi-Ruhrgas process. The solids are heated to a temperature of at least 1400.degree. F., and on contacting the crude, cause cracking of the viscous crude into lighter molecular weight hydrocarbons and form a solid coke-like residue on the sand grain. The sand grains containing the coke residue are transported into a second chamber into which air is injected and the solid coke residue ignited. The carbon coke residue burns, raising the temperature of the sand or other granular solids. A portion of the hot solids are recycled into the thermal cracking unit, and another portion are transported to a steam generator unit into which dirty water, e.g., water containing high concentrations of suspended particulate matters such as sand, clay, silt, etc. is introduced. The rate of hot solids introduction and water injection into the steam generating unit are controlled so as to produce steam of the desired quality for use in a steam injection viscous oil recovery method.
Abstract:
In producing cracked gas and cracked oil by thermally cracking a heavy hydrocarbon within a reactor in which a granular solid, steam and oxygen form a fluidized bed or moving bed, a process which is characterized in that the heavy hydrocarbon is supplied to the upper portion of the reactor and part of the granular solid is discharged from the bottom of the reactor and thereafter fed again to the upper portion of the reactor, to thereby maintain the upper portion at a temperature of not higher than 550.degree.C.
