(1) The basis for the specification of reaction conversion.
(2) Report conversion in the output report. Only the conversion of BASE component will be calculated and reported in output, in addition to the regular information-- feed, change, and product rates.
(3) User added kinetics
When user added kinetics (User added subroutine or inline procedure) is used, the reaction rate of component A from a particular reaction equation is calculated as:
Rate(A) = stoich coeff (A) / stoich coef (BASE) * user kinetic reaction rate of that particular reaction
Therefore, when PRO/II power law is used, the change of BASE component does not affect the solution. When user kinetics is used, the solution can be changed.
Presently, the above is valid only for reactor unit op. and not for reactive distillation. As per Richard Yu, when user kinetics is used the reactive distillation calculates the component reaction rate without the "stoich coeff (BASE)" term. This will be corrected. Starting from version 4.0 both reactor and reactive distillation will consistently use the above rate equation for user added kinetics.
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.
