Modeling an Industrial Lime Slaking Process

摘要

In this work a semi-physical model is developed for an industrial dry lime slaking process. The model is based on mass and heat balances for two non-stationary ideal stirred tank reactors in series. The mass balance equations are described by twopartial differential equations. It is shown how the total reaction rate is derived from the conversion rate for lime particles. The evaporation model is based on experimental data from the pilot plant slaker. The slaker model is simulated and compared toa step response experiment performed on the slaker.
