An apparatus and method for sulfur recovery uses a scrubber tower with a plurality of vertically spaced scrubber trays in the tower. Sulfide-lean liquor is supplied to each of the trays and an acid gas is supplied to the tower below the trays. A downcomer extends in the tower and through the trays for accumulating liquid from the trays and moving the liquid to the bottom of the tower. The sulfide-lean liquor and acid gas are selected to form a sulfite-rich or sulfide-rich liquor in each of the trays which are brought to the bottom of the tower through the downcomer for removal from the tower.

Apparatus to recover sulfur from concentrated acid gas into alkaline solution

A compact, mobile fuel converter for producing molecular hydrogen from hydrocarbon fuels, such as automotive gasoline, or other fuels such as methanol and ethanol has a steam reformer for producing molecular hydrogen from a pressurized and desulfurized fuel and water vapor preheated by flue gases from the fuel processor. The fuel processor is fed with the desulfurized fuel and water mix and a burner is provided to combust off-gas from the fuel processor reaction. Uncombusted off-gas is depressurized and mixed with auxiliary fuel used in the burner. Hydrogen produced in the fuel processor by the steam reforming process is separated from other reformate products using membrane filtration.
