Abstract: A solid/fluid separation module and apparatus enables treatment of solid/fluid mixtures to generate a filtered mass having a solids content above 50%. A filter unit with stacked filter plates and filter passages recessed into a face of each filter plate is provided.

Abstract: A process and system for producing a synthetic hydrocarbon having a desired H/C ratio is disclosed. Organic material is biochemically digested in a two stage biodigester for separately producing a hydrogen containing biogas substantially free of methane in a first stage and a methane containing biogas in a second stage. The methane containing biogas is reformed in a first reformer to generate hydrogen gas and carbon monoxide gas, which are then combined in a mixer with the hydrogen containing biogas into a syngas in amounts to achieve in the syngas an overall H/C ratio substantially equal to the desired H/C ratio. The syngas is reacted with a catalyst in a second reformer, a Fischer-Tropsch (FT) reactor, to produce the hydrocarbon. Using a two stage biodigester allows for the generation of separate hydrogen and methane streams, a more economical generation of the FT syngas and reduced fouling of the FT catalyst.

Abstract: A solid/fluid separation module and apparatus enables treatment of solids with enclosed fluids to generate a filtered mass having a solids content above 50%. A split filter module with first and second filter blocks clamped together for forming barrel sections or filtering sections is disclosed for use in a solid/fluid separating device including a barrel and a conveyor screw in the barrel. The split filter module permits replacement, maintenance, or repair of the filter blocks without disassembly or the separating device, or removal of the conveyor screws.
