  • Patent number: 10435340
    Abstract: A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound, comprising introducing a feed stream comprising said mixture into a first distillation column, introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column, introducing an aqueous stream below the feed stream into the first distillation column.
    Type: Grant
    Filed: September 5, 2014
    Date of Patent: October 8, 2019
    Assignees: SCG CHEMICALS CO., LTD., GTC TECHNOLOGY US, LLC

  • Patent number: 10427994
    Abstract: Process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound, comprising distilling said mixture in a distillation column in the presence of an extractive solvent, characterized in that the distillation column is operated at a sub-atmospheric pressure.

  • Patent number: 9765264
    Abstract: A process for reducing the bromine index (BI) of a hydrocarbon feedstock, for example an aromatic hydrocarbon feedstock. Removal of contaminants, more specifically bromine-reactive contaminants such as unsaturated hydrocarbons (e.g., olefins) cause the reduction in the bromine index (BI) of the hydrocarbon feedstock. The process involves providing an adsorbent, such as a zeolite.
