Vapor Liquid Equilibrium Data in Tert-Amyl Methyl Ether (TAME) Production
TAME (tert-amyl methyl ether) is used as a high-octane gasoline blending component.
Producing TAME involves the following three simultaneous reactions:
2M1B+MeOH ⇄ TAME (etherification)
2M2B+MeOH ⇄ TAME (etherification)
2M1B ⇄ 2M2B (isomerisation)
where MeOH is methanol while 2M1B and 2M2B (unsaturated C5 isoamylenes) are 2-methyl-1-butene and 2-methyl-2-butene, respectively.
In the system considered here, -pentane is an inert present in the reacting quinternary mixture.
This Demonstration uses the UNIQUAC (UNIversal QUAsi-Chemical) activity coefficient prediction model in order to compute vapor-liquid isobaric diagrams at 1 atm for the 10 possible binary combinations. Such results are preliminary calculations useful in order to perform steady-state and dynamic simulations of reactive distillation columns used for the production of TAME.
