A process can be used for purifying a hydrocarbon stream containing at least Cx alkanes, Cx olefins, low boilers such as Cx−1 hydrocarbons, and high boilers such as Cx+1 hydrocarbons, with x=3 or 4. The process involves separating off low boilers and separating off high boilers, wherein the separating-off of high boilers is performed in the presence of hydrogen and hence a hydrogenation of the olefins present takes place.

Process for removing extraneous odour-forming substances from hydrocarbon streams

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.

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 separating butenes from C4 hydrocarbon streams, with subsequent oligomerisation

A method for separating butenes from C4 hydrocarbon streams containing butanes and butenes involves extractive distillation with a suitable solvent. The method also involves heat integration, which makes it possible to use the heat of the solvent in order to heat 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.
