Abstract: A process for the production of polymers from waste plastics feedstocks includes: providing a hydrocarbon stream A obtained by treatment of a waste plastics feedstock; optionally providing a hydrocarbon stream B; 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); performing a thermal cracking operation in the presence of steam to obtain a cracked hydrocarbon stream D; supplying the cracked hydrocarbon stream D to a separation unit; performing a separation operation in the separation unit to obtain a product stream E comprising a monomer; supplying the product stream E to a polymerisation reactor; and performing a polymerisation reaction to obtain an polymer. The process 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 method of producing one or more olefins and one or more lubricating base oils is disclosed. The method includes hydrocracking hydrocarbons of a hydrocarbon feed stream that include vacuum gasoil to produce a stream that includes hydrocracked hydrocarbons. The method further includes fractionating the stream that includes hydrocracked hydrocarbons to form intermediate streams. The method further includes steam cracking one or more of the intermediate streams to produce at least one olefin and processing one or more of the intermediate streams to produce at least one lubricating base oil.
