Good initial estimates for recycle streams and columns should aid model convergence. From PRO/II 7.1 onwards, users can update their recycle stream estimates, in a solved model, by selecting the Update Recycle Stream Initial Estimates from the Input menu. All recycle streams will be updated with solution data.
Column initial estimates can also be generated/updated from a solved model. The column initial estimates can be updated by either by selecting the Update Column Initial Estimates from the Input menu; or by right clicking on the column and selecting the Update Column Initial Estimates option. If used, the Update Column Initial Estimates option, will use solution data for heater/cooler duty estimates and provide column temperature, net vapor and liquid rate profiles.
About PRO/II: PRO/II is the major product in the Process Engineering Suite (PES). This process simulation software optimizes plant performance by improving process design, operational analysis, and performing engineering studies. It is designed to perform rigorous heat and material balance calculations for a wide range of chemical processes. PRO/II allows users to evaluate the use of heat integration with case studies, rigorously evaluate process improvements with the help of a process flow diagram (PFD), or model crude distillation units. PRO/II offers a wide variety of thermodynamic models to virtually every industry and is incredibly cost effective, decreasing both capital and operating costs.
Technical Support: As always, feel free to reach out to your local technical support team for more information.
