Optimizing Strategy for Three Effects Following Flow Evaporation Process of Sodium Hydroxide Solution

A new optimizing strategy is developed,It is suitable for an actual threeeffects evaporation process. The method can be used to search the optimum order of evaporatorsby taking the treatment quantities as objective function,The 'inside-out' algorithm is usedto solve the mathematical decoupled model by dividing model equations into groups.The inneriterative loop is a equal-area designing procedure,the outer loop is a corrective step. Theconvergence is very stable and fast.Based on the calculation of an actual industrial cXample,if a process is reformed following the strategy,not only the production capacity can beincreased,but also the s team needed be reduced.
