Abstract: Methods for recovering organic heteroatom compounds from a hydrocarbon feedstock include feeding into a contactor a hydrocarbon feedstock and an aqueous solvent to form an extraction mixture of the aqueous solvent with the hydrocarbon feedstock. The hydrocarbon feedstock includes a hydrocarbon and an organic heteroatom compound. The aqueous solvent includes an ionic liquid formed from pressurized carbon dioxide and water.

Then, the solvent complex is extracted to a recovery vessel from the extraction mixture in the contactor. By adjustment of a recovery temperature of the recovery vessel, a recovery pressure of the recovery vessel, or both, the solvent complex decomposes into carbon dioxide and the organic heteroatom compound. The organic heteroatom compound is then recovered from the recovery vessel.

Abstract: An electrochemical cell, electrochemical cell assembly and a method of assembling an electrochemical cell assembly. The cell includes a pair of current collectors that when joined together form a three-dimensional electrode assembly with an ion-exchange membrane disposed between the anode and cathode of the electrode assembly. The current collectors are sized and shaped such that a three-dimensional reactant chamber volume of one of the current collectors accepts nested placement of at least a portion of the three-dimensional reactant chamber volume of the other current collector. This design allows for easy and direct addition, removal or replacement of cells in a stack of such cells in a modular fashion. In addition, ease of mounting and unmounting of the cells on reactant manifolds promotes ease of assembly of two-dimensional or three-dimensional stack structures.
