  • Method for separating butenes from C4 hydrocarbon streams, with subsequent oligomerisation
    Patent number: 11964940
    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.
    Type: Grant
    Filed: January 21, 2022
    Date of Patent: April 23, 2024
    Assignee: Evonik Oxeno GmbH & Co. KG
    Inventors: Philip Lutze, Stephan Peitz, Armin Matthias Rix, Tanita Valèrie Six, Moritz Schröder, Niklas Paul

  • Energy-efficient process for removing butenes from C4-hydrocarbon streams and subsequent n/iso separation
    Patent number: 11945777
    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.
