Dynamic simulation of multiple-effect evaporation
The main purpose of this work is to simulate multiple-effect evaporation and its variation as a result of the interconnection between batch and continuous unit operations. Therefore, the challenges posed by the hybrid continuous-discrete character of the model are addressed. The computer code is bas...

| description | The main purpose of this work is to simulate multiple-effect evaporation and its variation as a result of the interconnection between batch and continuous unit operations. Therefore, the challenges posed by the hybrid continuous-discrete character of the model are addressed. The computer code is based on detailed fundamental material and energy balance equations, physical and thermodynamic properties, and well-proven correlations for the heat transfer coefficients. A sugarcane industry was used to demonstrate the effectiveness of the model; in this industry, there is an interconnection between a batch and a continuous process. The steam consumed in the batch process changes in each batch step. The results showed that changing the steam flow rate changes the pressure of the steam produced in a multiple-effect evaporation. Additionally, when a bypass valve and a relief valve are used to maintain constant steam pressure, it increases the overall steam consumption. |
