Abstract: A method for separating butenes from C4 hydrocarbon streams containing butanes and butenes involves extractive distillation with a suitable solvent, and a subsequent adiabatic oligomerisation. The method also involves heat integration, which makes it possible to use the heat of the solvent in order to heat and/or at least partly evaporate various streams.

Abstract: Oligomerization of C3- to C5-olefins using a catalyst is inhibited, wherein the oligomerization is carried out in at least one reaction stage including at least one reactor and at least one distillation column, and wherein the oligomer content in the feed stream to the at least one reactor of the at least one reaction stage is at least 1% by weight.

Abstract: The present invention relates to a process for oligomerization of C2- to C8-olefins in at least two reaction stages, wherein in the last distillation column the reaction mixture is fractionated such that only very small amounts of the reactant olefins and the analogous alkanes remain in the bottom of the distillation column.

Abstract: A process for removing butenes from C4-hydrocarbon streams containing butanes and butenes involves extractive distillation with a suitable solvent. The process also involves heat integration, which allows utilization of the heat of the solvent for heating and/or at least partly evaporating various streams.

Abstract: The invention provides a process for removing organic constituents from a gas stream in a two-stage scrubbing operation, in which scrubbing is performed firstly with an alcoholic scrubbing medium and then with an aqueous scrubbing medium. The laden scrubbing media obtained can be used in certain (chemical) processes.
