2015-11-5  Lime reburning is the process of converting lime mud sludge (essentially, CaCO3) generated in the causticizing plant to reburned lime (CaO) that takes place at high temperatures in a rotary lime kiln, which is both a chemical reactor and heat transfer device. In this project, a control strategy was developed for the lime kilns in a Brazilian pulp mill in order to reduce the variability on calcination process and decrease the consumption of fuel. This control strategy was developed based on the concept of APC (Advanced Process Control) with automatic generation of set points, that varies depend on the characteristics of the process. It works according to thermodynamic principles of lime kiln operation and based on the physic-chemical of combustion and calcination reactions. In this project, a multivariable controller was developed in the DCS, through which the main control variables for the lime kiln
