Abstract: A contactor/separator is formed from a vessel; an inlet for receiving a vapor/liquid mixture; an inlet for receiving a superheated vapor; a hub located within the vessel, the hub including a plurality of vanes for imparting a centrifugal motion to the vapor/liquid mixture or the superheated vapor; an outlet in a bottom of the vessel for removing liquid; and an outlet for removing vapor from the vessel. A method is also provided for heating and separating liquid and vapor from a hydrocarbon feedstock comprising introducing a hydrocarbon feedstock into a contactor/separator: introducing a superheated vapor into the contactor/separator such that it contacts and vaporizes a portion of the feedstock within the contactor/separator; separating unvaporized feedstock from vaporized feedstock in the contactor/separator; removing the vaporized feedstock and the superheated vapor through a first outlet; and removing the unvaporized feedstock through a second outlet.

Abstract: A hydrotreating method (HDT) utilizes two plants working under different operating conditions with an intermediate stripping for co-treating a mixture made up of oils of vegetable or animal origin and petroleum cuts (gas oil cuts (GO) and middle distillates) in order to produce gas oil fuel bases meeting specifications. The first plant (HDT1) is more particularly dedicated to the reactions concerning oils of vegetable or animal origin in comixture while pretreating the hydrocarbon feed, whereas the second plant (HDS2) works under more severe conditions to obtain diesel fuel according to standards, in particular in terms of effluent sulfur content, density and cold properties.

Abstract: A process for the recovery and purification of a contaminated hydrocarbons, wherein the contamination includes metals, finely divided solids and non-distillable components. The process further includes hydroprocessing the oil to remove deleterious compounds, to produce high quality reusable lubricants, solvents and fuels and to improve the quality of water byproduct.

Abstract: A catalyst support in the shape of a non-planar ring having a bore; wherein there is no rotational symmetry around the axis extending through the centre of the bore defined by the ring, and wherein the ratio of the thickness of the ring to the outer diameter of the ring is less than 0.5. The catalyst support shape is especially advantageous to pack within a fixed bed multitubular reactor such as that used for Fischer-Tropsch reactions. The packing of such shapes can reduce the pressure drop across the tubes with little or no difference in the porosity.

Abstract: A process for producing normally gaseous olefins from two different process units sharing common downstream quench and fractionation facilities, wherein one of the process units is a short contact time mechanically fluidized vaporization unit for processing petroleum residual feedstocks and the other is a conventional steam cracking unit.

Abstract: The present invention relates to an integrated fluid coking/hydrogen production process. The fluid coking unit is comprised of a fluid coker reactor, a heater, and a gasifier. Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to the scrubbing zone of the reactor. Methane and steam are introduced into the stream of hot solids passing from the gasifier to the scrubbing zone. The hot particles act to catalyze the conversion of methane to carbon monoxide and hydrogen in the presence of steam.

Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to a satellite reactor. A light paraffin stream is introduced into directly into this stream of hot solids passing to the satellite reactor or into the satellite reactor. The hot particles act to catalyze the dehydrogenation of the paraffins to olefins.

Abstract: An integrated fluid coking/paraffin dehydrogenation process. The fluid coking unit is comprised of a fluid coker reactor, a heater, and a gasifier. Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to the scrubbing zone after first being reduced in temperature by introduction of an effective amount of diluent, such as steam. A light paraffin stream is introduced into this stream of hot solids between the point where the diluent is added and the scrubbing zone. The hot particles act to catalyze the dehydrogenation of paraffins to olefins.

Abstract: Hydrocarbon feeds are dewaxed and hydrotreated in a two-stage dewaxing-hydrotreating reactor system with interstage separation of olefinic and naphtha and light olefins. Separation of the naphtha and olefins is carried out by stripping the effluent from the dewaxing reactor with a stripping medium such as make-up hydrogen or vapor from the hydrotreater effluent. Hydrogen recycle for the dewaxer and the hydrotreater is taken from the stripper/separator after removal of the olefinic naphtha and removal of contaminants. Separation of the lighter olefins from the olefinic naphtha may be improved by the use of an oil solvent such as naphtha introduced into the top of the interstage stripper/separator so that the recycle gas from the stripper/separator is essentially free of wet gas and heavier fractions.
