PROCESS FOR THE PREPARATION OF POLYETHYLENES FROM WASTE PLASTIC FEEDSTOCKS

The present invention relates to a process for the production of ethylene-based 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) 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 ethylene; (g) supplying the product stream E to a polymerisation reactor; and (h) performing a polymerisation reaction in the polymerisation reactor to obtain an ethylene-based polymer; wherein in step (d): ⋅the coil outlet temperature is ≥800 and ≤870° C., preferably ≥820 and ≤870° C.; and ⋅the weight ratio of steam to feed C is >0.3 and <0.8. Such process allows for optimisation of the quantity of waste plastic material that finds its way back into a polyethylene that is produced as outcome of the process. The higher that quantity is, i.e. the higher the quantity of chemical building blocks that are present in the waste plastic material that are converted to the produced polyethylene, the better the sustainability footprint of the process is. The process allows for circular utilisation of plastics. In addition, the process allows for increased efficiency in the production of polyethylene in that the fraction of ethylene in the cracked hydrocarbon stream D is increased. A further advantage of the process of the present invention is that the overall energy consumption towards polyethylene is reduced.
