DYNAMIC SIMULATION OF A NON-ISOTHERMAL MSMPR CRYSTALLIZER
Chemical Engineering Communications, 1984 The effect of including temperature variations in the dynamic simulation of an MSMPR cooling crystallizer is investigated. Power law nucleation and growth kinetic models incorporating an Arrhenius temperature dependence are used. The effects of changes in the input variables feed temperature, feed flowrate and feed concentration on the output variables
