    摘要： The present invention relates to a process for the production of butenes and butadienes from waste plastics feedstocks comprising the steps in this order of: (a) providing a hydrocarbon stream A obtained by hydrotreatment of pyrolysis oil produced from a waste plastics feedstock; (b) optionally providing a hydrocarbon stream B; (c) supplying a feed C comprising a fraction of the hydrocarbon stream A and optionally a fraction of the hydrocarbon stream B to a thermal cracker furnace comprising cracking coil(s); (d) performing a thermal cracking operation in the presence of steam to obtain a cracked hydrocarbon stream D; (e) supplying the cracked hydrocarbon stream D to one or more separation units; (f) performing a separation operation to obtain different streams of chemical products comprising ethylene, propylene, isobutene, 1-butene, 2-butene, 1,2-butadiene, 1,3-butadiene, benzene, styrene, toluene, ethylbenzene and xylenes; wherein in step (d): the coil outlet temperature is >800 and 805 and 0.3 and 0.3 and

    摘要： An apparatus designed to completely vaporize an intake of heavy hydrocarbon feedstock is described. The apparatus, a so-called heavy feed mixer, is comprised of pipes being disposed coaxially about a common longitudinal axis. The inner tubular section delivers a two-phase liquid-vapor mixture of hydrocarbon feedstock and dilution steam to the apparatus. The converging/diverging tubular section has a unique structure which converges to a throat section and then diverges to an outlet section. The converging section directs a uniform shroud of superheated steam onto the hydrocarbon stream delivered by the inner tubular section. Impingement of the superheated steam with the intake stream initiates mixing and further vaporization within the throat section. The mixture traverses the converging/diverging tubular section and passes into the outlet section where vaporization is complete. The completely vaporized stream is directed out of the apparatus for further processing downstream.

    摘要： A method for thermally cracking a hydrocarbonaceous feed wherein the feed is first processed in an atmospheric thermal distillation step to form a light gasoline and atmospheric residuum mixture. The light gasoline/residuum combination is gasified at least in part in a vaporization step, and the gasified product of the vaporization step is thermally cracked.
