  • Separations system for recovering hydrocarbons from synthesis of polyethylene polymers
    Patent number: 11851518
    Abstract: The present disclosure provides for a separations system for separating ethylene, 2-methylbutane and at least one unsubstituted (C6-C12) hydrocarbon in a multi-component condensate mixture. The separations system includes a feed conduit in fluid communication with a source of the multi-component condensate mixture, a stripper column in fluid communication with the feed conduit, where the stripper column separates the multi-component condensate mixture into a heavies component mixture with at least one unsubstituted (C6-C12) hydrocarbon, and a top mixture having a medium component (s) that include at least the 2-methylbutane and a light component (s) that include at least the ethylene. The separations system further includes a flash drum that separates the top mixture into the medium component (s) and the light component (s). The separations system does not include a distillation column disposed between the source of the multi-component condensate mixture and the flash drum.
