Abstract: A process for the production of white oil includes adding a supercritical fluid (propane, butane or carbon dioxide) to the base oil and hydrogen injected into a reactor for hydrogenation. The base oil and supercritical fluid use high-pressure injector pumps as the feed system. The feed system for hydrogen uses a high-pressure compressor to compress hydrogen from a hydrogen tank to a storage tank, then a mass flow controller is used to steadily feed the hydrogen. A static mixer mounted in line, upstream from the inlet of the reactor mixes the reactant well. Several thermocouples are connected to the reactor, inlet and outlet of said reactor to measure the temperatures of the reaction. The detected data from the thermocouples are transferred to a six-point thermograph. The pressure of the reaction is maintained by a back pressure regulator that is mounted downstream from the outlet of said reactor. After the hydrogenation reaction is complete, the pressure of the fluid in the outlet of the reactor is reduced. A vapor-liquid separator is used to separate the vapor and liquid. The total flow of the vapor is recorded using a gas meter.

Abstract: A process for concurrently fractionating and hydrotreating of a full range naphtha stream. The full boiling range naphtha stream is first subjected to simultaneous thioetherification and fractionation to remove the mercaptans the light fraction and then to simultaneous hydrodesulfurization and splitting of the remainder into an intermediate boiling range naphtha and a heavy boiling range naphtha. The three boiling range naphthas are treated separately according to the amount of sulfur in each cut and the end use of each fraction.

Abstract: A hydrocracking process wherein a hydrocarbonaceous feedstock and a hot hydrocracking zone effluent containing hydrogen is passed to a denitrification and desulfurization reaction zone to produce hydrogen sulfide and ammonia to thereby clean up the fresh feedstock. The resulting hot, uncooled effluent from the denitrification and desulfurization zone is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the preceding reaction zone with a hydrogen-rich gaseous stream to produce a vapor stream comprising hydrogen, hydrocarbonaceous compounds boiling at a temperature below the boiling range of the fresh feedstock, hydrogen sulfide and ammonia, and a liquid hydrocarbonaceous stream.

Abstract: A process for catalytic multi-stage hydrogenation of heavy carbonaceous feedstocks using catalytic ebullated bed reactors is operated at selected flow and operating conditions so as to provide improved reactor operations and produce increased yield of lower boiling hydrocarbon liquid and gas products. The disclosed process advantageously takes advantage of an external gas/liquid separation unit associated with the first stage reactor to allow for a more efficient and effective catalytic hydrocracking process. The more efficient process is primarily a result of the increased catalyst loading and lower gas hold-up in the ebullated reactors.

Abstract: In the refining of crude oil, vacuum gas oil hydrotreaters and hydrocrackers are used to remove impurities such as sulfur, nitrogen, and metals from the crude oil. Typically, the middle distillate boiling material (boiling in the range from 250° F.-735° F.) from VGO hydrotreating or moderate severity hydrocrackers does not meet the smoke point, the cetane number or the aromatic specification. In most cases, this middle distillate is separately upgraded by a middle distillate hydrotreater or, alternatively, the middle distillate is blended into the general fuel oil pool or used as home heating oil. With this invention, the middle distillate is hydrotreated in the same high pressure loop as the vacuum gas oil hydrotreating reactor or the moderate severity hydrocracking reactor. The investment cost saving and/or utilities saving are significant since a separate middle distillate hydrotreater is not required A major benefit of this invention is the potential for simultaneously upgrading difficult cracked stocks such as Light Cycle Oil, Light Coker Gas Oil and Visbroken Gas Oil or Straight-Run Atmospheric Gas Oils utilizing the high-pressure environment required for mild hydrocracking.

Abstract: Savings in the processing of a naphtha boiling range feed containing a thiophene are achieved by fractionating the feed stream in a single dividing wall column to yield a C6-minus overhead stream, a side-draw containing the majority of the C6 and C7 paraffins and olefins, and a bottoms stream comprising C7 and heavier hydrocarbons. A dividing wall column provides better control of the concentration of both thiophene and toluene in the side-draw. Less of the valuable naphtha is lost and the amount of thiophene in the overhead product is minimized.
