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.

Process for removing butenes from C4-hydrocarbon streams and two-stage evaporation

Energy-efficient process for removing butenes from C4-hydrocarbon streams

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.

Method for preventing three-phase separation of butenes from C4 hydrocarbon streams

Energy-efficient process for removing butenes from C4-hydrocarbon streams and subsequent n/iso separation

An extractive distillation column system contains a combination column and a side rectification column. A process can be used for separation of butenes from C4-hydrocarbon streams using the extractive distillation column system.
