Abstract
The presence of sulfate and carbonate ions in the aluminate liquors results in the creation of scale on heat exchange surfaces during heating and evaporation. As inhibitor the liquid silicone polymers of siliconate type was used. Inhibitor is added directly into the substance. The effect of inhibitor concentration on the degree of sulfate and carbonate sediments encrustation of heat exchange surface of evaporator equipment was found. The results obtained in pilot and industrial conditions showed that with increasing concentration of inhibitor the speed of encrustation slows down. Complete cessation of encrustation achieved with the addition of inhibitor in the liquor is evaporated in amount of about 35 ppm. The results of using the inhibitor are expressed in steam consumption reduction for evaporation and grow capacity.
