Definitions
- the present invention relates to the refining and the conversion of heavy hydrocarbon fractions containing, inter alia, sulfur-containing impurities. It relates more particularly to a process for the conversion of heavy petroleum feedstocks of the atmospheric residue and / or vacuum residue type for the production of heavy fractions that can be used as fuel bases, in particular as bunker oil bases with a low sediment content.
- the process according to the invention also makes it possible to produce atmospheric distillates (naphtha, kerosene and diesel), vacuum distillates and light gases (C1 to C4).
- the sediment content according to ISO 10307-1 (also known as IP375) is different from the sediment content after aging according to ISO 10307-2 (also known as IP390).
- the sediment content after aging according to ISO 10307-2 is a much more stringent specification and corresponds to the specification for bunker fuels.
- a ship may therefore use a sulfur-containing fuel oil if the ship is equipped with a flue gas treatment system that reduces emissions of sulfur oxides.
- Fuel oils used in shipping generally include atmospheric distillates, vacuum distillates, atmospheric residues and residues. under vacuum from direct distillation or from refining process, including hydrotreating and conversion processes, these sections can be used alone or in mixture. These processes, although known to be suitable for heavy loads loaded with impurities, however, produce hydrocarbon fractions that may include catalyst fines and / or sediments that must be removed to satisfy a product quality such as bunker fuel oil.
- the sediments may be precipitated asphaltenes.
- the conversion conditions, and in particular the temperature, cause them to undergo reactions (dealkylation, polycondensation, etc.) leading to their precipitation.
- the existing sediments in the heavy cut at the end of the process measured according to ISO 10307-1, also known as IP375
- These sedimentation phenomena generally occur during the implementation of severe conditions (high temperature and residence time) giving rise to high conversion rates, for example greater than 35, 40 or 50% or more, and this depending on the nature of the charge.
- the formation of potential and / or existing sediments also tends to increase with the aging of the catalysts.
- the conversion ratio is defined as the mass fraction of organic compounds having a boiling point above 520 ° C in the feed at the inlet of the reaction section minus the mass fraction of organic compounds having a higher boiling point. at 520 ° C at the outlet of the reaction section in the effluent, all divided by the mass fraction of organic compounds having a boiling point above 520 ° C at the inlet of the reaction section in the feedstock.
- waste treatment processes there is an economic interest in maximizing conversion because, generally, conversion products, especially distillates, are better valued than the unconverted feed or fraction.
- the temperature is generally lower than in bubbling bed or slurry bed hydrocracking processes. The conversion rate in fixed bed is therefore generally lower, but the implementation is simpler than bubbling bed or "slurry".
- the conversion rate of hydrotreatment processes in fixed bed is moderate or low, generally less than 45%, usually less than 35% at the end of the cycle, and less than 25% at the beginning of the cycle.
- the conversion rate generally varies during the cycle due to the increase in temperature to compensate for the catalytic deactivation.
- sediment production is generally lower in fixed bed hydrotreatment processes than in bubbling bed or slurry bed hydrocracking processes.
- temperatures sometimes reached from the middle of the cycle and up to the end of the cycle for fixed bed residue hydrotreating processes can lead to a sufficient sediment formation to degrade the quality of an oil, especially an oil. bunker, consisting largely of a heavy fraction from a process of hydrotreatment of residues in fixed bed.
- the skilled person is familiar with the difference between fixed bed and bed in "slurry".
- a "slurry" bed is a bed in which the catalyst is sufficiently dispersed in the form of small particles to be suspended in the liquid phase.
- FR 2 983 866 discloses a continuous process for treating a hydrocarbon feedstock.
- bypassable reactor is meant a reactor, which can be stopped by the implementation of a “by pass” while the other reactors of the unit are still in operation. Unlike the so-called reactive reactors that can be put back into service while the other (or other) reactor (s) of the unit is (are) in operation, the bypassable reactors can be shut down at any time and usually restarted only when restarting the entire unit
- a bypassable reactor can be erased at any time and for a longer or shorter duration of the production scheme, while a switchable reactor necessarily stops in favor of another. which restarts.
- Another advantage of the new process incorporating a hydrocracking step in passable reactors is that it becomes possible to operate these hydrocrackable reactors at an average temperature over the entire cycle that is higher than that of the reactors.
- the fixed bed hydrotreatment section thus leading to a higher conversion without the formation of sediment, generally increased by the higher temperature, is problematic for the quality of the product.
- the temperature of the by-passable reactor requiring the shutdown of the reactor is between 405 ° C and 425 ° C.
- the passable hydrocracking section is stopped in such a way as to prevent the generation of sediments, in particular potential sediments, while allowing hydrotreatment to be continued on the upstream reactors.
- the hydrocracking section is implemented from the beginning of the cycle of the unit and for at least 30% of the cycle, or even at least 50% of the cycle.
- the stopping temperature of the hydrocracking section in passable reactors is to be determined by the operator by monitoring the sediment content of the effluent, in particular the potential sediments, as soon as the sediment content after aging ( IP390) is greater than 0.05 or 0.08% by weight for example, it is time to stop the hydrocracking section in passable reactors.
- the average temperature of the process is a mass weighting of the average temperatures of the different beds. It is calculated taking into account for each reactor its average temperature and its weight of catalysts.
- the weighted average temperature will be calculated as (T1 * m1 + T2 * m2) / (m1 + m2).
- the catalysts of the hydrotreatment section are little deactivated and therefore active at moderate temperatures which leads to the production of very stable effluents with no sediment, there is therefore an interest in exploiting this margin of stability by applying a hydrocracking step in passable reactors operating at a higher temperature and allowing a gain in conversion.
- the coking and the increase of the pressure drop are not problematic in the hydrocracking section, since the bypassable reactors can be stopped without stopping the unit, which then makes it possible to reduce the pressure drop of the section. reaction by subtraction of the loss of charges from the reactors by passables.
- the invention relates to a method as defined in claim 1.
- One of the objectives of the present invention is to propose a process coupling conversion and desulphurization of heavy petroleum feedstocks for the production of fuel oils and low-sulfur fuel oil bases.
- Another objective of the process according to the invention is the production of bunker fuels or bunker oil bases with a low sediment content, that is to say, after aging less than or equal to 0.1% by weight, this being achieved by the implementation of steps a), b), c) and d) during the first part of the cycle, then by stopping the reactors by passables in the second part of the cycle.
- Another object of the present invention is to jointly produce, by the same method, atmospheric distillates (naphtha, kerosene, diesel), vacuum distillates and / or light gases (C1 to C4).
- the bases of the naphtha and diesel type can be upgraded to refineries for the production of automotive and aviation fuels, such as, for example, super-fuels, Jet fuels and gas oils.

During the next cycle, it is possible to restart with the switchable hydrodemetallization reactor Rb at the head.
