Abstract
In the present study several defoaming agents were investigated in a b atch-crystallizer with respect to their effectiveness on habit modific ation and filterability of gypsum crystals. The application of some ag ents in an horizontal tube falling film evaporator is discussed. Furth ermore, the recrystallization kinetics of gypsum to anhydrite in the p resence of sodium chloride at 95 degrees C are presented.
