  • Process improvement for desulfurization unit

    Abstract: A desulfurization system employing fluidizable and circulatable finely divided solid sorbent particulates that are transported between reactor, regenerator, and reducer vessels. Agglomeration of the sorbent particulates is minimized and circulation of the sorbent particulates is enhanced by controlling the location at which the sorbent particulates are withdrawn from the reducer.
