Abstract: The present disclosure relates to methods for producing renewable base oil and other valuable renewable fuel components from a feedstock of biological origin comprising free fatty acids and glycerides. The feedstock is first separated to two or more effluent streams containing a fatty acid fraction and glyceride fraction. The glycerides are hydrolyzed to free fatty acids and glycerol, and the fatty acids thus obtained are recycled to the separating. The fatty acids are then converted to the base oil by ketonisation, hydrodeoxygenation and hydroisomerisation. The glycerol is converted to propanols by selective hydrogenolysis.

Abstract: An integrated production plant system includes, at one production site at least two plants of different kinds selected from a renewable paraffinic fuel plant to produce renewable paraffinic fuel in a renewable paraffinic fuel process, a renewable fatty acid alkyl ester (FAAE) fuel plant to produce renewable FAAE fuel in a renewable FAAE process, a renewable base oil plant to produce renewable base oil in a renewable base oil process, and a renewable chemical plant to produce renewable chemical in a renewable chemical process. Each of the processes is provided with a respective renewable feed, where the feed of each of the processes originates from a common renewable system feed, and the feed to at least one of the processes is altered for example by directing at least part of the feed of at least one of the processes to another of the processes.
