IRAN Y1 - 2012 PY - 2012 VL - 31 IS - 3 SP - 61 EP - 73 KW - Cumulative Mass Fraction (CMF) KW - CMSMPR crystallizer KW - frequency response KW - Simplified model DO - 10.30492/ijcce.2012.5953 N2 - In this contribution, linearized dynamic model of Cumulative Mass Fraction (CMF) of Potassium Nitrate-Water Seeded Continues Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer is approximated by a simplified model in frequency domain. Frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. However, the CMF frequency response of the original model is obtained versus three input variables encompass seeding mass flow rate, inlet liquid volumetric flow rate and jacket temperature with emphasis on minimum model simplification assumptions. Results show that the simplified CMF frequency response predicts system dynamics and covers all system characteristics as well as the main complex model.
