Patent number: 12006480Abstract: The present disclosure relates to methods for processing liquefied waste polymers (LWP) containing diolefins. The LWP feed is supplied to steam stripper A to provide a distillate containing diolefins and naphtha, and a distillate bottom. The distillate is subjected to hydrotreatment B to produce a diolefin depleted distillate which is separated by distillation C to give rise to one or more fractions comprising at least a naphtha fraction, an optional middle fraction and a bottom fraction. Hydroprocessing D of the naphtha fraction gives rise to hydrogenated naphtha which is suitable as a feed for a steam cracker E. Since the distillation bottom, bottom fraction and the middle distillate are predominantly free from diolefins, they can be mixed with crude oil and processed further in oil refinery.Type: GrantFiled: October 29, 2021Date of Patent: June 11, 2024Assignee: NESTE OYJInventors: Pekka Aalto, Heikki Aaltonen, Antti Ojala, Andrea Pérez Nebreda, Emma Sairanen, Ville Paasikallio, Antti Kurkijärvi
