Definitions

  • An integrated process for hydroconverting and steam cracking hydrocarbons comprising hydroconverting (particularly hydrodesulfurizing) a hydrocarbon to produce a hydroconverted hydrocarbon and heat; generating steam, using as part of the energy required the heat produced in the hydroconver'sion step; and contacting the hydroconverted hydrocarbon and' the steam in a steam-cracking zone to form low-sulfurcontent products.
  • the heat produced in hydroconverting a lighter hydrocarbon fraction can be used in producing the steam.
  • This invention is directed to an integrated process for hydroconverting hydrocarbons and steam crack ing hydrocarbons, combining processing steps in a highly efficient, integrated manner.
  • the invention is directed to the use of the heat generated in an exothermic hydroconversion process as part of the energy necessary for generating superheated steam for steam cracking of hydrocarbons. It is particularly directed to an integrated process whereby heavy hydrocarbon oil feedstock is first hydrofmed with the concomitant production of heat; the heat from the hydroconversion process step. e.g., hydrofining, is recovered at least in part and used as part of the energy necessary to generate superheated steam; and the superheated steam, together with the hydrofined hydrocarbon, is fed to a steam-cracking zone, wherein the hydrocarbon oil is cracked to form tar and pitch as well as cycle oil and lighter gases.
  • the hydroconversion process step(s) is carried out at conventional temperatures and pressures.
  • a temperature of fromabout 500 to. 900F., preferably 650 to 850F., is used.
  • the hydrogen supply rate (makeup and recycle hydrogen) to the hydroconversion zone is inthe range of from about 5.00 to about 20,000 standard cubic feet per barrel of hydrocarbon feed, preferably about 2,000 to about.5,000 standard cubic feet per barreloAs noted above, while hydrodesulfurization will generally be the primary concern in the hydrofining zone, hydrodenitrification may also be of importance, dependent upon the hydrocarbon feedstock.
  • the catalyst employed in the hydroconversion Zone(s) is comprised of material having hydrogenationdehydrogenation activity, together with an active cracking component.
  • exemplary cracking components include silica-alumina, silica-magnesia, silica-aluminazirconia composites, acid-treated clays.
  • crystalline aluminosilicate zeolitic molecular sieve such as zeolite A, faujasite, zeolite ,X and zeolite Y.
  • Hydrogenationdehydrogenation components of the catalyst preferably comprise at least one hydrogenation component selected from Group VI metals and compounds of Group VI metals and at least one hydrogenation component.
  • Preferred combinations of hydrogenation components include nickel sulfide with molybdenum sulfide, cobalt sulfide with molybdenum sulfide,
  • noble-metal-containing catalysts may also be used.
  • the preferred hydrofining catalyst is comprised of a carrier of alumina together with hydrogenation components of Group VI and Group VIII metals and compounds thereof, in which discrete, substantially insolu- 3,493,517, both of which patents are incorporatedherein by reference.
  • the steam cracking of hydrocarbons is carried out at a temperature in the range of from about l,500 to about 3,000F., preferably l,600 to 2,700F., and under a pressure in the range of from 6 to 300 psi absolute, preferably 14.7 to about 150 psi absolute.
  • the treating time is in the range of from about 0.001 to about 0.1 seconds or, preferably, 0.003 to 0.05 seconds.
  • the hydrocarbons fed to the steam-cracking zone may be sent directly to the steam-cracking zone without any intermediate cooling. That is, if the hydrocarbon fed to the steam-cracking zone is first hydrofined, the product may be sent to the steam-cracking zone at a temperature in the range of from 400 to 700F.
  • FIG. 1 represents a preferred embodiment of the present invention
  • crude oil is fed via line 1 to atmospheric distillation column 2.
  • Atmospheric residuum is removed by line 3, and sent to vacuum distillation column 4.
  • the vacuum gas oil fraction is taken off via line 5, combinedwith a heavy atmospheric gas oil (line 6) and fed via line 8 to hydrofining zone 9.
  • the vacuum residuum in vacuum distillation column 4 is fed via line 10 to residuum hydrofining zone 11.
  • a light gas oil is removed from column 2 and fed via line 7 to hydrocracking zone 12.
  • the effluents from hydroconversion zones 9, l1 and 12 are passed through steam boilers l3, l4 and 15, respectively, wherein heat is removed from effluent streams 16, 17 and 18, respectively.
  • Steam is generated from the water passed through steam boilers 13, 14 and 15 by lines 19, and 21, respectively.
  • Lines 19, 20 and 21 pass the steam generated in boilers 13, 14 and 15 to superheated-steam generator 22.
  • Superheated steam is then fed by line 23 to steam cracking zone 24.
  • the effluent from hydrofining zone 11 is fed by line 17 to steam-cracking zone 24.
  • the effluent from steamcracking zone 24 is fed byline 25 to fractionator 26, where pitch, gas oil and other products are separated.
  • the atmospheric gas oil need not be combined with the vacuum gas oil before feeding to hydrofining zone 9.
  • the gas oil obtained from fractionator 26 may be subjected to steam cracking to produce unsaturated hydrocarbons such as ethylene, propylene and butadiene, using superheated steam generated using as part of the energy required the heat from a hydroconversion zone. Further, as pointed out above, it may be .desirable to send the hydrofined hydrocarbons from hydroconversion zone 11 directly to the steam-cracking zone without intermediate cooling.
  • the basic concept of the'subject invention is the use of the heat generated in any or all of hydroconversion zones 9, 11 and 12 for producing the superheated steam used in the steam-cracking ing equipment for preheating the feed to the steamzone.

Particularly preferred feedstocks are vacuum residua and other heavy hydrocarbon feedstocks such as reduced topped crude oils, atmospheric residua, crude shale oils, coal tar distillates, and the like. Mixtures of crude.
  • Feedstocks used preferably contain substantial quantities of materials boiling above 1,000F Lighter feedstocks, such as light gas oils, ethylene cracker bottom oil, and the like, may also be used.
  • the feedstock to the steamcracking zone be first hydrofined to reduce sulfur content.
