IMPROVED DESULFURIZATION PROCESS

摘要

A hydrocarbon desulfurization system includes a fluidized bed reactor (12), a fluidized bed regenerator (14), and a fluidized bed reducer (16). Fluidizalbe solid particles circulate through the raator (12), generator (14), and reducer (16) 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 (12), the regenerator (14), and the reducer (16). The transport system uses close-coupled vessels and gravity flow between various vessels to minimize equipment cost and particle attrition.
