Abstract
At heating and evaporation of aluminate liquors the liquid organic silicon polymers of siliconate type were used. This type of material is characterized by antiadhesive properties and at sufficient surplus of polymer, can cover an inside wall of the heat exchange tubes with a thin layer on which the sodalite is less likely to stick. This reagent can greatly reduce or even completely eliminate sodalite scaling in heat exchangers, pipes, etc. what are confirmed in pilot plant, and plant tests. Obtained positive data at heating and vaporization of high silica liquors at presence of 50–100 mg/l (15–30 ppm to dry substance) scale inhibitor allow concluding about an opportunity of heating and vaporization these liquors in heat exchangers of recuperative type. The result of use of the inhibitor is expressed in decrease in the charge of vapor to the evaporation and increase in its throughput.
