Abstract: The present invention 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 invention also relates to an apparatus for use in the process and use of a fractionator in dehydration of a feedstock containing tall oil.

Abstract: The present disclosure describes a process for producing poly-α-olefins. The process includes providing at least one α-olefin monomer and a catalyst, and letting the at least one α-olefin monomer react in the presence of the catalyst to form a mixture of poly-α-olefins (PAO). The obtained mixture of poly-α-olefins is fractionated to two PAO fractions wherein the two PAO fractions are a first fraction of PAO having a kinematic viscosity of 5 cSt or lower and a second fraction of PAO having a kinematic viscosity of more than 5 cSt. Optionally a recycle fraction is also obtained in the fractionation and at least a part of the recycle fraction including dimers of the α-olefins can be recycled back to the reaction step.

Abstract: 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.
