  • Patent number: 10435487
    Abstract: A process for separation of a hydrocarbon-containing feed stream can include cooling the hydrocarbon-containing feed stream using an absorption refrigeration cycle to form a cooled feed stream. The cooled feed stream can be subjected to distillation conditions to remove a bottom stream including co-monomer; and an overhead stream including hydrocarbon diluents, olefin monomer, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead stream can be subjected to distillation conditions adapted to remove a bottom stream including substantially olefin-free hydrocarbon diluents; a side stream including hydrocarbon diluent; and an overhead vapor stream including olefin monomer, diluents, and components selected from H2, N2, O2, CO, CO2, and formaldehyde. The overhead vapor stream can be cooled using an absorption refrigeration cycle to form a cooled overhead vapor stream. Olefin monomers can be separated from diluents in the cooled overhead vapor stream.

  • Patent number: 9238182
    Abstract: The present invention relates to a process for recycling product streams that have been separated from a hydrocarbon-containing feed stream comprising olefin monomer, olefin co-monomer, hydrocarbon diluent and components such as H2, N2, O2, CO, CO2, and formaldehyde.

  • Patent number: 8188198
    Abstract: The present invention relates to a process for cooling a polymerization reaction for producing polyolefin comprising the steps of: (a) thermally contacting said polymerization reaction with a cooling fluid such that the cooling fluid removes thermal energy from said reaction, (b) thermally contacting said cooling fluid with a working fluid thereby recovering said thermal energy from said cooling fluid in said working fluid, and (c) thermally contacting the cooling fluid obtained in step (b) with the polymerization reaction thereby cooling said reaction, wherein the working fluid is phase converted thereby providing energy in the form of heat and/or electricity and/or mechanical power back to the polyolefin production process. Said invention also relates to a polymerization process for producing olefin polymers in a reactor, and also relates to a process for energy optimization of energy consumption in a polymerization process and to a polymerization unit.
