Title: Process for controlling the ph of an electrolytic sulfur dioxide scrubbing system
IPC: C25B1/22
Filed: 1969-01-17
Abstract: 1,248,284. Electrodialysis. IONICS Inc. Jan. 17, 1969 [April 1, 1968], No.2747/69. Heading C7B. SO 2  is removed from a SO 2 -containing gaseous mixture and recovered as a concentrated stream by (a) partially converting an aqueous feed solution of sodium, potassium, ammonium or magnesium sulphate into its corresponding acidic and alkaline solutions by introducing it under pressure into the centre compartment 3 of a three compartment electrolytic cell 1, in which the centre compartment is separated from an anode compartment 2 by a micro-porous diaphragm 4 and from a cathode compartment 5 by a cation permselective membrane 6, to produce an alkaline e. g. NaOH solution at the cathode 11 and an acidic e. g. NaHSO 4  solution at the anode 7; (b) contacting the effluent alkaline solution (from outlet 13), together with a reducing agent (from feed line 41) more susceptible to oxidation than bisulphite, with the gaseous mixture e. g. in an absorber 19 to absorb SO 2  and form a bisulphite salt e.g. NaHSO 3  solution; and (c) combining the HSO 3  with the effluent acidic solution (from outlet 8), e. g. in a heated neutralizer-stripper tank 35, to reform the SO 4  solution, which is recycled back as feed solution (via line 42) to the cell, after stripping off the desorbed SO 2  (via exit line 44). With Na salts, the reducing agent is preferably sodium thiosulphate or dithionate and/or an electrolytic reduction product of NaHSO 3 , e.g. sodium di-, tri-, tetra-, perta-, hexa-thionite ("hydrosulphite") produced by recycling (via line 32) a part of the NaHSO 3  obtained from the aborber 19 back to the cathode compartment 5 into which water may also be introduced (via inlet 12). The reducing agent may be a polythiolstyrene, polyvinyl-hydroquinone, formaldehyde-phenol-hydroquinone, cuprous or ferrous complexed, or an electron exchange resin. The above reducing agent prevents oxidation of the bisulphite to bisulphate due to residual oxygen, nitrogen oxide, persulphates or other oxidants entering the system e.g. in fly-ash, thus controlling the pH of the feed solution being recycled, preferably in the range 6-9. The diaphragm 4 may be of rubber ceramic, poly-ethylene or -propylene or "Teflon" (Registered Trade Mark). The cation permselective membrane 6 is preferably of the self supporting reinforced carboxylic acid type, e. g. formed by copolymerizing divinyl benzine and an anhydride, ester or acid chloride of acrylic acid and saturating with water or an aqueous or alcoholic solution of acid or base. The anode 7 may be of Pb or Pb alloys of Ag, Sb, Te and/or T1, W bronze, Pt or Pt-coated Nb, Zr, Ta or Ti; the cathode 11 may be of Cu, Pb (or alloy), Ni, Fe or steel. A plurality of three compartment cells may be placed in stack arrangement with common bimetallic bipolar electrodes e.g. of Ni-Pt.
