Methanol

We use a batch column with four theoretical plates to separate a binary mixture of water and methanol at 1 bar. Temperature and concentration profiles versus time are obtained for a reflux ratio equal to 10. In addition, the total moles in the still and distillate are plotted versus time. This...

Computation of the residue curve map for the MTBE chemistry is presented in the program. The equilibrium, taking place in the liquid phase, transforms methanol and isobutene into MTBE with n-butane being an inert component. Thermodynamic data can be found in the excellent paper by Niang and...

The program computes residue curves for a ternary mixture composed of acetone, chloroform and methanol.Wilson model is used to get activity coefficients. The program is composed of two parts; one for positive warped time and the other for negative warped time. Initial conditions have been chosen...

n the bottom of a Stefan tube there is a quiescent liquid with a mixture of acetone (component 1) and methanol (component 2). Vapor that evaporates from this pool of liquid diffuses to the top of the tube. Air (component 3) keeps the mole fractions of components 1 and 2 equal to zero. This...

The batch rectification unit consists of seven theoretical plates, a reboiler and a reflux drum. We fill the reboiler with a 2500 kmol of a mixture of acetone-methanol. Initially, the mixture contains a liquid mole fraction of acetone equal to 40 % mole. The vapor flow rate is set equal to 10...
