ADDITIVE TO WATER FOR PREVENTING SEDIMENT FORMATION ON HEATING SURFACE*PARTICULARLY OF HEATED SEA WATER DESALTING INSTALLATIONS

摘要

The reaction product of long-chain unsaturated hydrocarbons (fatty derivatives) with maleic acid anhydride and/or maleic acid is added to the salt-containing water of a thermal desalination installation to increase the solubility of the calcium and magnesium salts and prevent encrustation of heating surfaces thereby.
