Numerical modelling and simulation of liquid-impelled loop reactor

A liquid-impelled reactor (LLR) system was modelled using macro-and micro-balance technique. The relative goodness of using macro-balance was evaluated by comparing its solutions with the results obtained using micro-balance modell. The micro-balance modell formulated was used to investigate the dynamic behaviour of the system and to crosscheck the effectiveness of macro-balance modell. A numerical solution of the micro-balance modell was obtained, with which the system was simulated and the results were compared with the analytical solution of the macro-balance modell in order to compare their ability to effectively describe the system. The results showed a perfect correlation between the solutions obtained using analytical and numerical techniques. This is an indication that the system can be described or modelled using both microbalance and macro-balance. Also, the type of empirical correlation used to estimate the mass transfer coefficient influences the dynamic behaviour of the system. M.S.C. 2000: 00A71, 00A72, 00A99, 34B60, 65P99, 93A30, 93A99.
