The current disclosure relates to an apparatus and a process for producing poly-α-olefins (PAO), including reacting olefin monomers in a presence of a catalyst complex to form PAO product. The reaction is performed in a reaction including a reactor vessel and a system for recycling and cooling part of reactor outlet stream. At least one reactor is a cone reactor with a first cross sectional area in an upper part of the vessel and the cross sectional area decreases downwards to a second cross sectional area, which is smaller than the first cross sectional area.

Process and apparatus for producing poly-alpha-olefins

The present disclosure relates to a process for treating a feedstock containing tall oil, the process including separation of a light stream from the feedstock, followed by removal of a heavy fraction from the feedstock, in which process the separation of the light stream from the feedstock a fractionator is used and at least one product is collected from the light stream. The disclosure also relates to an apparatus for use in the process and use of a fractionator in dehydration of a feedstock containing tall oil.

The present disclosure relates to hydrogenation reactions of different fractions in oil refining. It also relates to a process device applicable thereto for hydrogenation of various feedstocks, such as arrangements during campaign changes.

Process and apparatus for hydrogenation

The present description is related to the field of hydrocarbon production by gasification of carbonaceous material. It provides a two-stage gas washing method as a part of gas refining. More specifically it discloses a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. It introduces a use of a novel combination of wash approaches for this application. As a specific application, this process is utilized as a part of biomass to liquid (BTL) process.

Two-stage gas washing method

Disclosed is a method relating to hydrocarbon production by gasification of carbonaceous material, for example, a two-stage gas washing method as a part of gas refining. Disclosed is a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. Disclosed is a use of a combination of two chemical wash approaches. The process can be utilized as a part of biomass to liquid (BTL) process.
