The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.

Process for integrated production of renewable fuels and chemicals

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.

Flexible integrated production plant system and method

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.

A method for adjusting hydrogen to carbon monoxide ratio of syngas contaminated by sulfur impurities involving a water gas shift (WGS) reaction. In light of the presence of the sulfur impurities, the WGS can be implemented as a sour gas shift. WGS can provide good results by using a non-sulfided catalyst. Conditions can be employed which contribute to further enhanced CO-conversion in the reaction. The hydrocarbons or derivatives thereof obtainable from the method can further be refined and used for production of fuels or lubricants for combustion engines.
