Abstract

1454657 Treating saline water CIBAGEIGY (UK) Ltd 16 April 1975 [30 April 1974] 18980/74 Heading C1C [Also in Division C7] Saline water is treated to prevent scaling in evaporators by adding a mineral acid to neutralize a part of the bicarbonate alkalinity and a scale-inhibiting additive, the amount of acid being such that the pH is not reduced below 7À5. The invention also comprises the acid/scale inhibitor compositions. Specified acids are HCl and H 2 SO 4 and specified inhibitors are hydrolysed polymaleic anhydride, polyacrylic acid, a terpolymer of maleic anhydride, vinyl acetate and ethyl acrylate, amino-trismethylene-phosphonic acid, polymethacrylic acid and 1- amino-propane-1,1-bis-(phosphonic acid).
