Abstract: The present invention relates to a process for the production of polymers from waste plastics feedstocks comprising the steps in this order of: (a) providing a hydrocarbon stream A obtained by treatment of 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 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 a separation unit; (f) performing a separation operation in the separation unit to obtain a product stream E comprising a monomer; (g) supplying the product stream E to a polymerisation reactor; and (h) performing a polymerisation reaction in the polymerisation reactor to obtain an polymer. The process of the present invention allows for optimisation of the quantity of waste plastic material that finds its way back into a polymer that is produced as outcome of the process.

Abstract: A system and a method for steam cracking hydrocarbons are disclosed. The system includes a steam cracking system comprising a first steam cracking furnace and a second steam cracking furnace. A hydrocarbon feed stream is fed into a convection section of a first steam cracking furnace. The preheated feed stream is mixed with steam and then separated into a light vapor stream and a heavy stream in a vapor-liquid separation unit. The light vapor stream is further steam cracked in a radiant section of the first steam cracking furnace. The heavy stream is further heated and steam cracked in the second steam cracking furnace.

Abstract: A method of processing a plastic and a method of processing pyoil derived from a plastic. A numerical model for a correlation between chlorine content in one or more process streams of a steam cracking unit and a hydrocarbon to steam ratio in a feed stream of the steam cracking unit is constructed. A pyoil and naphtha blend is mixed with steam at a hydrocarbon to steam ratio obtain from the model to produce the feed stream for a steam cracking unit. The feed stream is processed in the steam cracking unit to produce olefins.
