Concerning this flowsheet - 2 questions.
1. What is the form of equation 119 for the reactions kinetics for column C1?
2. How were the constants derived for equation 119?

Re: TAME_iecr44p5715
The equation 119 is as follows: y = exp( a/t + b + c.t + d.t^2 + e.ln(t) ) where t is the temperature in degrees Kelvin. This is a common form for modeling reaction kinetics. The constants stem from the two articles referenced Ind.Eng.Chem.Res. Vol. 44 p 5715, namely:

* Subawalla, H.; Fair, J. R. Design guidelines for solid-catalyzed reactive distillation systems. Ind. Eng. Chem. Res. 1999, 38, 3693.
