Insights into Design Criteria for a Continuous, Sonicated Modular Tubular Cooling Crystallizer

A new designed sonicated, continuous modular crystallizer was investigated and developed. The concept and design criteria for the designed crystallizer were examined and Results showed that ultrasound had significant effects, which compounds which were K2SO4, CuSO4, and phthalic acid. studied in a cooling crystallization process with three model can enhance the nucleation and avoid clogging in the tubular crystallizer. The present work shows the obtained results when different cooling strategies were studied. Equal super saturation throughout the crystallization process was the best solution for designing temperature profiles for the modules. In addition to the cooling strategy, the residence time is one of the key factors to get feasible operating conditions in the designed crystallizer. Higher yields were obtained using ultrasound with phthalic acid crystallization, as a model compound, compared to a classical tubular flow reactor.
