  • Process and system for removal of light ends and non-condensables to prevent buildup in an olefin/paraffin membrane separation process
    Patent number: 11136280
    Abstract: Systems and processes are provided to prevent light ends such as methane, ethylene and ethane from building up in an olefin/paraffin separation system that uses a combination of a membrane and distillation column for this separation. In one embodiment a small stripper column is provided downstream from a selective hydrogenation reactor. In the other embodiment, a surge vessel with a receiver is added to the retentate stream of the membrane unit.

  • Processes for producing propylene from paraffins
    Patent number: 9051230
    Abstract: Embodiments of processes for producing propylene from paraffins are provided. The process comprises the steps of combining an effluent that comprises propylene and propane from a paraffin dehydrogenation reactor with an offgas stream that comprises propane to form a combined effluent stream. The combined effluent stream is separated into a propylene product stream and a propane-rich recycle stream. The propane-rich recycle stream is introduced to the paraffin dehydrogenation reactor operating at dehydrogenation conditions to convert propane in the propane-rich recycle stream to propylene.

  • METHODS AND SYSTEMS FOR OLEFIN PRODUCTION
    Publication number: 20130131417
    Abstract: One example method of the invention includes a process for producing an olefin comprising the steps of communicating a feed stream that comprises a paraffin to a distillation section, communicating a distillation section output stream to a reactor and reacting the distillation section output stream in the reactor to produce a reactor output stream comprising an olefin. A splitter feed stream that is in communication with and downstream from the reactor output stream is communicated to an olefin splitter, and a splitter output stream is communicated to a heat pump compressor. A heat pump compressor output stream is communicated to the distillation section and heat is used from the heat pump compressor output stream to reheat a distillation section stream that contains unreacted paraffin.
