  • Patent number: 7854835
    Abstract: A hydrocarbon desulfurization system that circulates fluidizable solid particles through a fluidized bed reactor, a fluidized bed regenerator, and a fluidized bed reducer to thereby provide for substantially continuous desulfurization of a hydrocarbon-containing fluid stream and substantially continuous regeneration of the solid particles. A novel transport system is employed for transporting the solid particles between the reactor, the regenerator, and the reducer. The transport system uses close-coupled vessels and gravity flow between various vessels to minimize equipment cost and particle attrition.
    Type: Grant

  • Patent number: 7172685
    Abstract: A hydrocarbon desulfurization system employing regenerable solid sorbent particulates in a fluidized bed desulfurization reactor. The sulfur-loaded sorbent particulates are continuously withdrawn from the reactor and transferred to a regenerator. A novel solids transport mechanism provides for the safe and effective transfer of the sulfur-loaded sorbent particulates from the high pressure hydrocarbon environment of the reactor to the low pressure oxygen environment of the regenerator.
