Abstract: Coal can be freed of ion-exchangeable sodium by contacting it with aqueous solutions of CO.sub.2 or formic or acetic acids at a mine mouth or contacting it with aqueous CO.sub.2 while transporting it in a pipeline.

Abstract: A process for removal of solid sulfur from specified solubilized iron chelate-containing solutions is described, the process being characterized by melting of the sulfur and maintenance of the solution during the melting and separation operations in the substantial absence of oxygen.

Abstract: A coal or similar carbonaceous fuel is selectively freed of sodium by water washing it and ion exchanging the washed coal with a strong aqueous electrolyte solution which is substantially free of sodium ions and contains a kind and concentration of ions which are correlated with the composition of the coal to cause a selective removal of ion-exchangeable sodium from the coal, with at least a significant proportion of the ion-exchanging being conducted within a pipeline.

Abstract: A process for the production of epichlorohydrin is disclosed which comprises reacting allyl chloride, chlorine and water to form an intermediate, then rapid conversion and separation of epichlorohydrin product; the epichlorohydrin-depleted reaction mixture is cooled and subjected to electrodialysis then reverse osmosis to concentrate and remove deleterious by-products, and at least a substantial portion of the resultant permeate is recycled to the reaction zone, thereby enabling reduced operating costs and/or improved yield.

Abstract: A continuous process for the production of dichlorohydrin by the reaction of allyl chloride, water and chlorine having substantially lower energy requirements than conventional processes, wherein the reaction mixture is subjected to reverse osmosis to concentrate the dichlorohydrin and to provide a permeate stream substantially free of dichlorohydrin, which permeate stream is recycled to the reaction.
