  • Processes and apparatuses for methylation of aromatics in an aromatics complex
    Patent number: 10556847
    Abstract: This present disclosure relates to processes and apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to processes and apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex using processed toluene instead of crude toluene.
    Type: Grant
    Filed: August 9, 2018
    Date of Patent: February 11, 2020
    Assignee: UOP LLC
    Inventors: Naiyl A. Rashid, Gregory B. Kuzmanich

  • Process for increasing xylene isomer to benzene ratio
    Patent number: 10118878
    Abstract: Apparatuses and processes are provided for regulating C7 and C8 feed to an aromatics complex to increase the ratio of a selected xylene isomer to benzene ratio. Reformate may be split into three cuts in a splitter column. A side cut stream comprises predominantly C7 hydrocarbons and a bottoms steam from the splitter column comprises predominantly C8+ hydrocarbons. The relative proportion of the C7 and C8+ hydrocarbon streams sent to the aromatics complex are metered to determine the resulting ratio of a selected xylene isomer to benzene produced by the aromatics complex.

  • LOW PRESSURE TRANSALKYLATION PROCESS
    Publication number: 20140100403
    Abstract: A process for transalkylation is described. The process operates at a lower pressure than a typical transalkylation processes, and provides higher benzene purity with comparable or lower ring loss compared to the typical transalkylation process. The xylene selectivity is comparable to or higher than the standard process, and the ethyl benzene selectivity is comparable to or lower than the standard process.
