  • Vaporisation in oxidation to phthalic anhydride
    Patent number: 9156018
    Abstract: In the production of phthalic anhydride by the oxidation of ortho-xylene with air, the ortho-xylene loading is increased without increasing the likelihood of explosion by insulating the system to avoid cold spots to keep the ortho-xylene at a temperature above its dew point; in addition the system may be electrically interconnected and grounded to reduce the risk of spark initiated explosions or deflagrations.
    Type: Grant
    Filed: January 21, 2014
    Date of Patent: October 13, 2015
    Assignee: ExxonMobil Chemical Patents Inc.
