Optimization of a Multiple-Effect Evaporator Process by Simulation

초록

Simulation is used to solve complex problems in the pulp and paper industry through process modeling based on the predicted values obtained to understand the characteristics and behaviors of the actual process of interest. The study aim was to evaluate a multiple-effect evaporator (MEE) model built using WinGEMS and determine the overall efficiency of the MEE based on different case studies of black liquor and steam feed arrangements. Efficiency was much better with the backward feed arrangement than with other models in terms of steam economy predicted. For more accurate simulation optimization in the MEE process, however, an actual dataset should be used to evaluate the mode efficiency. © 2022 Korean Technical Assoc. of the Pulp and Paper Industry.
