Hydrocracking process

The present invention describes a process for the production of base oils having a viscosity of greater than 4 centistokes from waste oils originating from industrial use or engine use, said process using a novel configuration for efficient and effective processing.

Process for production of on specification group III/III+ base oils while preserving base oil yield

The present invention concerns a device for filtration and distribution of a gaseous phase and a liquid phase, which can be disposed upstream of a fixed catalytic bed of a reactor operating with a descending co-current of gas and liquid, comprising: Each basket is provided support means cooperating with a riser of the plate in order to support the basket.

Filtering and distribution device for catalytic reactor

An installation for the hydrotreatment and hydroconversion of hydrocarbon-containing feedstocks, with a common fractionation section, for the production of at least one of the following products: naphtha (light and/or heavy), diesel, kerosene, distillate and residue: An integrated hydroconversion and hydrotreatment process implementing said installation.

Installation and integrated hydrotreatment and hydroconversion process with common fractionation section

The invention concerns a process and a facility for reducing the concentration of heavy polycyclic aromatic compounds (HPNA) in the recycle loop of hydrocracking units, which comprises a fractionation column. In accordance with this process, a portion of the stream present at the level of at least one plate located between the plate for supplying hydrocracked effluent and the plate for withdrawing the distillate fraction which is the heaviest is withdrawn from the fractionation column and at least a portion of said withdrawn stream is recycled to the column directly or after optional liquid separation, and optionally a portion of said withdrawn stream is recycled to the hydrocracking step directly or after optional gas separation.

Method and device for reducing heavy polycyclic aromatic compounds in hydrocracking units

The invention concerns a process and a facility for reducing the concentration of heavy polycyclic aromatic compounds (HPNA) in the recycle loop of hydrocracking units, which comprises a fractionation column. In accordance with this process, a portion of the stream present at the level of at least one plate (I) which is the supply plate or a plate located between the supply plate and the residue evacuation point, or if stripping gas is injected, between the supply plate and the stripping gas injection point, is withdrawn from the fractionation column. A portion, preferably all, of the withdrawn stream is recycled to the hydrocracking step directly or after optional separation of the gases. The residue is purged in its entirety.

The invention concerns a process and a facility for reducing the concentration of heavy polycyclic aromatic compounds (HPNA) in the recycle loop of hydrocracking units, which comprises a fractionation column. In accordance with this process, a stream is withdrawn from the fractionation column at the level of at least one plate located between the supply plate and the plate for withdrawing the heaviest distillate fraction; the stream is stripped in an external stripping step by a stripping gas, in the presence of a portion of the residue. The separated gaseous effluent is recycled to the column, advantageously as a stripping gas, and the liquid fraction is recycled to the hydrocracking step; a residue is purged in the stripping step.

The present invention describes a process for the production of technical white oils or edible or medicinal oils from waste oils originating from industrial use or engine use, said process using a deep hydrotreatment.

Process for the production of white oils from waste oils

A fluid mixing and distribution device for a catalytic downflow reactor, said device comprising a collection zone (A), a mixing zone (B) comprising a mixing chamber () for fluids and an exchange chamber () for fluids, a distribution zone (C), said exchange chamber () comprising at least one upper lateral cross-section of flow () and at least one lower lateral cross-section of flow () through which fluids can pass from said exchange chamber () to said distribution zone (C), characterized in that said exchange chamber () comprises a fluid deflection means () fixed to said exchange chamber () and located downstream of the upper lateral cross-section of flow (), said fluid deflection means () forming with said exchange chamber () a space () in the shape of a pan.

The invention relates to a process and installation for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) mild hydrocracking in a fixed catalyst bed, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment (including desulfurization) of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Advantageously, the heavy fraction is sent into catalytic cracking. The process preferably operates with make-up hydrogen that is brought to stage c), and very advantageously all of the make-up hydrogen of the process in introduced in stage c).

The invention relates to a process for treating heavy petroleum feedstocks for producing a gas oil fraction that has a sulfur content of less than 50 ppm and most often 10 ppm that includes the following stages: a) ebulliated-bed catalytic hydrocracking, b) separation from hydrogen sulfide of a distillate fraction that includes a gas oil fraction and a heavier fraction than the gas oil, c) hydrotreatment of said distillate fraction, and d) separation of a gas oil fraction with less than 50 ppm of sulfur. Make-up hydrogen, preferably all make-up hydrogen, is to stage c). Advantageously, the heavier fraction from step (b) is subjected to catalytic cracking. The invention also relates to an installation that can be used for implementing this process.
