  • Patent number: 11795401
    Abstract: Process 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 The molten plastic is withdrawn from the melt tank and fed to a pyrolysis reactor.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.

  • Publication number: 20230303934
    Abstract: An electrically heated furnace including one or more unit cells. Each unit cell includes a radiant heating section, one or more process coils disposed within the radiant heating section, and a quench unit for cooling a cracked product from the one or more process coils and producing a quenched reaction product. The furnace also includes one or more electrical heating elements disposed within the radiant heating section, the one or more electrical heating elements are arranged to provide radiant energy to the one or more process coils. Further, the electrically heated furnace includes a first area corresponding to a heating area of the one or more electrical heating elements, a second area corresponding to a wall area of the wall on which the one or more electrical heating elements are disposed, and a third area corresponding to a surface area of the one or more process coils.

  • Patent number: 11713220
    Abstract: Aspects of the disclosure include apparatus for and methods of facilitating transfer of objects using a crane. Disclosed apparatuses include a target tracking device mounted on or near a crane at a first location, and a target located near a landing location for the object. The target tracking device and the target facilitate real time determination of relative motion between the two locations. Methods of using the same are also disclosed.

  • Publication number: 20230227731
    Abstract: Systems and processes for pyrolyzing waste plastics, including, in one or more heating stages, heating a waste plastic from an initial temperature to a peak pyrolysis temperature, and, in a final pyrolysis stage, providing heat input sufficient to maintain a temperature of the waste plastic at a pyrolysis reaction temperature less than the peak pyrolysis temperature and maintaining the waste plastic at the pyrolysis reaction temperature for a time period to convert a portion of the waste plastic to a pyrolyzed product and a pitch. The process further includes recovering the pyrolyzed product and recovering the pitch.

  • Publication number: 20220089416
    Abstract: System for determining relative positions and/or relative motions between objects (103, 602, 604). Disclosed systems include a target tracking device (110, 620, 622) on a first object (602) and an optical target on a second object (604). The target tracking device comprises a camera to take images of the optical targets which is configured to track the optical target. The system comprises an onshore crane (601), a ship system (700), an aviation system (800) or an offshore crane (100). A controller (115, 615, 715, 815) controls the crane, a ship (701) or a helicopter (801) using the data from the tracking device.
