Abstract: A process for treating a temperature-sensitive hydrocarbonaceous stream containing a non-distillable component to produce a hydrogenated distillable hydrocarbonaceous product and a heavy product comprising the non-distillable component while minimizing thermal degradation of the hydrocarbonaceous stream which process comprises the steps of: (a) contacting the hydrocarbonaceous stream with a hot first hydrogen-rich gaseous stream having a temperature greater than the hydrocarbonaceous stream in a first flash zone at flash conditions including a first pressure thereby increasing the temperature of the hydrocarbonaceous stream and vaporizing at least a portion thereof to provide a first hydrocarbonaceous vapor stream comprising hydrogen and a first heavy product stream comprising the non-distillable component; (b) contacting the first heavy product stream comprising the non-distillable component with a hot second hydrogen-rich gaseous stream in a second flash zone at flash conditions including a second pressure

Abstract: A method of separating a hot hydrocarbonaceous stream having a temperature above the dew point of water and comprising hydrogen, vaporous hydrocarbonaceous compounds and an acidic inorganic compound which method comprises: (a) contacting the hot hydrocarbonaceous stream at a temperature above the dew point of water in a contacting zone with an aqueous alkaline solution in an amount sufficient to simultaneously neutralize the acidic inorganic compound and to cool the hot hydrocarbonaceous stream to a temperature below the dew point of water to produce a flowing stream comprising a hydrogen-rich gas, a liquid hydrocarbonaceous phase and an aqueous solution containing inorganic neutralization products; and (b) introducing the flowing stream produced in step (a) into a separation zone to gravitationally produce an aqueous phase containing inorganic neutralization products, a hydrogen-rich gaseous phase and a hydrocarbonaceous liquid phase.

Abstract: A process for converting the naphtha fractions distilled from crude oil into greater volumes than heretofore of a gasoline product having higher octane number and a distillate stream of improved cetane number and smoke point by sending the lower boiling naphtha fraction directly to the gasoline pool and subjecting the higher boiling naphtha fraction to a mild reforming treatment, extracting the reformate to separate two streams, aromatics which are directed to the pool and paraffins which are sent to a splitter to separate the paraffin stream into fractions greater than C.sub.8 and a C.sub.8 or less fraction. The C.sub.8 or less fraction is cracked, thermally or catalytically and alkylated and/or polymerized before being directed to the gasoline pool. The fraction from the splitter containing hydrocarbons greater than C.sub.8 can be used in the distillate pool.

Abstract: An improved catalytic reforming process is disclosed wherein hydrogen and light hydrocarbons generated in the catalytic reaction zone are passed to a hydrogen production/purification zone and are reacted and processed therein to produce substantially pure hydrogen. A portion of the hydrogen is then admixed with the charge stock to the catalytic reforming zone to provide the hydrogen requirements of the catalytic reforming reaction zone.

Abstract: A process for the production of a hydrogen-rich gas stream from the effluent of a catalytic hydrocarbon conversion reaction zone is disclosed. A hydrogen-containing vapor phase is recovered from the effluent and subjected to cooling in order to produce a hydrogen-rich gas stream. The resulting hydrogen-rich gas stream is expanded to provide the medium used in cooling the hydrogen-containing vapor phase.

Abstract: A catalytic reforming process is disclosed wherein the reboiler heat requirements of the stabilizer column are supplied by means of indirect heat exchange with hot combustion gases in the reforming reactants fired heater convection heating section. Heat in excess of the reboiler requirements is passed to the stabilizer column with control being effected by removal of excess heat from the column.
