SUSPENSION MELT CRYSTALLIZATION OF CAPROLACTAM

Investigations into the melt crystallization of caprolactam in suspens ion by means of a special developed an MSMPR crystallizer are presente d. The effect of the process operating conditions and the concentratio n of water in caprolactam on the kinetics of the crystallization and o n the median size of crystals was determined. The obtained results are presented in the form of relationships which can be used in the desig n of crystallizers for the melt crystallization of caprolactam and for the choice of operating conditions for a larger scale process.
