  • Process and apparatus for hydrocracking and hydroisomerizing a hydrocarbon stream
    Patent number: 10472581
    Abstract: A process and apparatus for quenching a hydrocracked stream to prepare it for hydroisomerization. A fractionated hydroisomerized stream is recycled to quench a hot hydrocracked stream prior to hydroisomerization. Sufficient quenching can inactivate the hydroisomerization catalyst bed. The hydroisomerization catalyst bed can be heated back to hydroisomerization temperature and can actively hydroisomerize again.
    Type: Grant

  • L-valve construction for controlling solids flow in a liquid medium using standard pipe fittings
    Patent number: 8753044
    Abstract: A new valve is designed for the transport of solids using a motive fluid. The valve includes an inlet conduit for carrying solids, where the solids are fed through gravity. The solids are carried by fluid transport out an outlet where the outlet conduit has a smaller diameter than the inlet conduit carrying the solids. The conduit should be sufficiently smaller to prevent instability in the flow. A second inlet provides the source of motive fluid to drive the transport of solids.

  • Method of fabricating a mixing chamber and a reactor relating thereto
    Patent number: 8323591
    Abstract: One exemplary embodiment can be a method of fabricating a mixing chamber in a hydroprocessing reactor. The method can include providing a first section forming an opening and coupling a second section including a sidewall to the first section. The second section forms a flange for coupling the mixing chamber and facilitating the mixing of one or more fluids.

  • Sprayer for at least one fluid
    Patent number: 8157990
    Abstract: One exemplary embodiment can be a sprayer for distributing at least one fluid in a vessel. The sprayer can include a first member having a first surface and a second surface forming at least one aperture there-through. Generally, the at least one aperture is skewed with respect to a substantially vertical axis passing through a center of the first member for distributing the at least one fluid in the vessel.
