Expert Optimizer Lime results in uniform lime quality with low energy consumption and reduced emissions. The Advanced Process Control solution analyzes residual carbonates during laboratory tests to optimize control targets and ultimately produce lime efficiently and economically.
The lime kiln operation in the kraft pulping recovery process, though straightforward in principle, can be challenging to operate at high efficiency. Some of the difficult issues faced by kiln operators include low thermal efficiency, high fuel consumption, process delays, build-up of rings and dust, overheating of refractory, poor quality of lime and increased emissions.
Expert Optimizer Lime manages these challenges to achieve optimum control and efficient lime production. The program works to optimize lime production rates; reduce energy consumption and emissions; increase re-burned lime availability; decrease residual carbonate variations; and improve the overall mill operation with increased visibility over the process. It combines laboratory results by operators with model-based predictive control, thus getting the best of both approaches in a fully product-specific solution, with minimum need for on-site development.
