Paper vs. MaximaLabs

We reproduce a published paper's flowsheet and kinetics in MaximaLabs and show both sets of numbers next to each other. A case study ships only once the replication is done and verified.

Reproducing the ethanol-water azeotrope (NRTL vs. Carey-Lewis 1932)

MaximaLabs's shipped NRTL package reproduces the 1932 Carey-Lewis ethanol-water VLE tie-lines to 0.18 K average bubble-point error and locates the azeotrope within 0.34 mol% and 0.1 K — no tuning.

J. S. Carey & W. K. Lewis, “Studies in Distillation: Vapor-Liquid Equilibria of Ethyl Alcohol–Water Mixtures,” Ind. Eng. Chem. 24(8), 882 (1932); as tabulated in Gmehling & Onken, DECHEMA Chemistry Data Series, Vol. I.
