Modeling rotary kiln aspen

Update date: Apr 13

Nov 14, 2021 This study assessed the energetic efficiency of a precalcining rotary kiln process in a cement industry. • Energetic efficiency was estimated as 61.30 % using Aspen Plus process simulator and artificial neural network (ANN) model predict with correlation coefficient (R 2) of 0.991.. Optimal energy efficiency of 61.5 % was established for the operation parameters; kiln feed of 205050 kg/hr
