  • CONVERSION OF WASTE PLASTICS TO PETROCHEMICALS
    Publication number: 20240010921
    Abstract: Processes and systems for converting waste plastics include feeding a waste plastic to a melt tank, and in the melt tank, heating the waste plastic to form a molten plastic. The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor. In the pyrolysis reactor, the molten plastic is heated to a pyrolysis temperature, producing a pyrolysis oil product and a liquid pitch product. The pyrolysis oil is then separated into a pyrolysis gas fraction, a light pyrolysis oil fraction, a medium pyrolysis oil fraction, and a heavy pyrolysis oil fraction.
    Type: Application
    Filed: September 20, 2023
    Publication date: January 11, 2024
    Applicant: LUMMUS TECHNOLOGY LLC
