Abstract

1488084 Regenerative electrolysis for H 2 and O 2 production WESTINGHOUSE ELECTRIC CORP 20 Jan 1975 [29 Jan 1974] 2383/75 Heading C7B An aqueous solution containing oxidizable anions is electrolyzed to produce H 2 and oxidize the anions; the oxidized anions in the form of a compound with H<SP>+</SP> are recovered and the compound thermochemically decomposed to generate oxygen and a residue corresponding to the anions; and the oxygen is recovered while the residue is returned to the electrolysis zones. In Fig.3 a series-parallel batch of cells with cation-selective membranes and hollow electrodes with internal spargers is used to electrolyze an aqueous solution of SO 2 , producing H 2 SO 4 as anolyte. This acid is preheated at 313, removing water and vaporized at 311, heat being supplied via an external heatexchanger 41a, whose secondary circuit 315 drives turbine 319 connected to compressor 317 and D.C. generator 325. The H 2 SO 4 vapour is decomposed catalytically with V in reactors 337, 339 and the products SO 2 , H 2 O, O 2 and SO 3 are passed via internal heat exchangers to a vapour-liquid separator 349 where dilute H 2 SO 4 is recovered and recycled. Decomposition energy is supplied externally through heat-exchanger 41b and excess energy from this and from the cooling of the decomposition products is utilized in turbines 363, 366, 368 to generate electricity. The SO 2 /O 2 mixture passes through further separators 379, 395, 401 where SO 2 is liquefied and recycled while O 2 is recovered. References 377 and 385 are coolers for the gas mixture and 373 is a heat-exchanger. Compressor 383 drives the cooling circuit. Full details of the thermodynamics of the system of Fig.3 are given.
