An apparatus and process for liquid removal from a mixture with solid particulate materials utilizing a screw conveyor within a housing for transport of solids, the screw conveyor upcoming side being in proximity to the housing means and the screw conveyor downcoming side being spaced from at least a portion of the housing means to form a liquid collection volume from which the liquid is removed.

Solids dewatering apparatus and process

An improved valve apparatus for the introduction of finely divided coal solids into a vessel in a controlled manner is disclosed. The disclosed apparatus includes substantially vertical and horizontal conduits interconnected to provide a generally continuous L-shaped flow path therethrough. Gas is introduced directly into the bottom portion of the vertical conduit upstream from the point where the vertical conduit and horizontal conduit interconnect. The flow rate of the gas introduced into the vertical conduit is controlled to adjust the amount of coal solids discharged from the discharge end of the horizontal conduit.

Coal conversion apparatus

An electrode assembly comprising a high voltage electrode having a generally cylindrical shape and being electrically connected to a high voltage source, where the cylinder walls may be open to flow of fluids and solids; an electrically grounded support electrode supporting said high voltage electrode by an electrically insulating support where both of the electrically grounded and electrically insulating support may be hollow; and an electrically grounded liner electrode arranged concentrically around both the high voltage and support electrodes. This assembly is specifically adapted for use in a fluidized bed chemical reactor as an improved heating means therefor.
