  • ENERGY-EFFICIENT PROCESS FOR SEPARATING BUTENES FROM C4-HYROCARBONS STREAMS
    Publication number: 20260193156
    Abstract: The invention relates to a process for separation of butenes from C4-hydrocarbon streams containing not only the butenes but also butanes by extractive distillation with a suitable solvent. The process according to the invention features heat integration with which the heat of the solvent is utilized for heating and/or at least partially evaporating different streams and the use of a heat pump for electrification of the process.
