Definitions
- the present invention relates to a method and an installation for the treatment of charges heavy hydrocarbons containing sulfur impurities. It concerns a process making it possible to at least partially convert such a charge of hydrocarbons, for example a vacuum distillate obtained by direct distillation of crude oil, in diesel fuel meeting the 2005 sulfur specifications i.e. having less than 50 ppm sulfur, and a product heavier which can advantageously be used as a filler for catalytic cracking (such as catalytic cracking in a fluid bed).
- the treated charges are heavy, that is to say that 80% by weight boils above 340 ° C.
- Their initial boiling point is usually at least 340 ° C, often at least 370 ° C see at least 400 ° C.
- the method makes it possible to treat charges having a final boiling temperature of at least 450 ° C and which can even go beyond 650 ° C.
- the sulfur content is at least 0.05% wt, often at least 1% and very often at least minus 2% or even at least 2.5% wt. Loads of 3% or more sulfur are suitable well in this process.
- the fillers which can be treated in the context of the present invention are distillates under direct distillation vacuum, vacuum distillates from conversion process such as example those from coking, from hydroconversion in a fixed bed (such as those from HYVAHL® processes for treating heavy products developed by the applicant) or hydrotreating processes for heavy in a bubbling bed (such as those from the H-OIL® processes), or deasphalted oils with solvent (for example with propane, butane, or with pentane) coming from the deasphalting of residue under direct distillation vacuum, or of residues from the HYVAHL® and H-OIL® processes.
- the charges can also be formed by mixture of these various fractions.
- the fillers which are treated are preferably vacuum distillates.
- Step a) - The charge as described above is treated in step a) by mild hydrocracking.
- VVH hourly space velocity
- the hourly space velocity (VVH) and the partial pressure of hydrogen are chosen according to the characteristics of the product to be treated and the desired conversion. Most often the VVH is in a range from about 0.1 h -1 to 10 h -1 and preferably about 0.2 h -1 to about 5 h -1 .
- the total quantity of hydrogen mixed with the feed (Chemical consumption H 2 + recycling) and therefore entering the zone in which step a) is carried out is usually about 100 to about 5000 normal cubic meters (Nm3) per meter cube (m3) of liquid charge and most often around 100 to around 2000 Nm3 / m3, generally it is at least 200 Nm3 / m3 and preferably around 200 to around 1500 Nm3 / 3.

- the partial pressure of hydrogen sulfide is preferably less than 0.05 MPa, preferably at 0.03 MPa, even better at 0.01 MPa.
- the ideal catalyst In the hydrodesulfurization zone, the ideal catalyst must have a strong hydrogenating power so as to achieve a deep refining of the products and to obtain a significant reduction in the sulfur.
- the hydrotreating zone operates at temperature relatively low which goes in the direction of a deep hydrogenation therefore of a improvement in the aromatic content of the product and its cetane and a limitation of the coking. It would not go beyond the scope of the present invention to use in the area hydrotreating simultaneously or successively a single catalyst or several different catalysts.

- the gasolines and the gas oils resulting from the conversion process are very refractory to hydrotreating if they are compared to gas oils produced directly from the atmospheric distillation of crudes.
- the critical point is the conversion of species the most refractory, particularly the di and trialkylated dibenzothiophenes or more for which the access of the sulfur atom to the catalyst is limited by the alkyl groups.
- the way of hydrogenation of an aromatic cycle before the desulfurization by breaking the Csp3-S bond is faster than direct desulfurization by rupture of the Csp2-S bond.
- Conversion gas oils therefore require very severe operating conditions to meet future sulfur specifications. If we want to hydrotreat these diesel fuels conversion under operating conditions allowing investment to be maintained moderate with a reasonable cycle time of the hydrotreatment catalyst, a optimization of the integration of process equipment is necessary.
- the amount of make-up hydrogen introduced in this step c) is greater than the chemical consumption of hydrogen necessary to obtain the performances fixed in the operating conditions set for this step c).

- a suitable means of measuring the hydrogen content in the feed or the liquid effluent is the 1 H NMR measurement.
- chromatographic analysis is suitable for the gaseous effluent.
- step c) all of the makeup hydrogen necessary for the process is introduced in step c). Consequently, the quantity supplied will also take account of the chemical consumption of hydrogen in stage a) so as to supply the hydrogen necessary for the hydrogenation sought in stage a) also.
- Another consequence is that it is possible to optimize the hydrogen supply in the step c) according to the refractory level of the gas oils to be treated.

- the hydrogen is separated from the effluent. It contains small amounts of hydrogen sulfide and usually does not require treatment.
- the hydrogen sulphide is also separated from the liquid effluent and thus a gas oil with at most 50 ppm by weight of sulfur is obtained, and most often with less than 10 ppm by weight of sulfur. Naphtha is also generally obtained.
- the hydrogen-containing gas which has been separated in step b) is, if necessary, at least partially treated to reduce its H 2 S content (preferably by washing with at least one amine) before recycling it to step a) and possibly in step c).
