The program computes the residue curve map for the ternary mixture benzene-toluene-p-xylene. When you change the mouse's position, a new residue curve is computed and displayed. Residue curve maps play an important role in the conceptual design of distillation columns. The pointer's position gives an initial point from which the simulation runs forward and backward in warped time. The lightest (benzene) and the heaviest (p-xylene) components...
The method uses finite differences to solve Laplace equation and matrix inversion to solve the resulting system of linear algebraic equations. The rectangular plate has both dimensions set equal to unity. Each dimension is discretized and the...
LU Decomposition is applied to a sparse banded matrix. We show how fill-ins can make solution by elimination not manageable. The same matrix is used to solve the Poiseuille flow problem in a rectangular channel using the finite differences...
One must input to a dialog box Antoine's constants, Wilson binary interaction parameters and liquid molar volume of any binary mixture of his choice. The program computes and plots activity coefficients, relative volatility and VLE diagram.
The code uses the SRK EOS written for a single component to plot isotherms, compute gas and liquid molar volumes and to plot vapor pressure versus temperature for ethane.

The program computes phase envelopes for two binary mixtures containing ethane and benzene (20 % ethane and 80 % benzene; 70 % ethane and 30 % benzene). This binary system exhibits a peculiar behavior called retrograde condensation (e.g. We get...
Uses Simulink to compute Vapor-Liquid Equilibrium diagrams for ethanol-water binary mixture. To compute activity coefficients, program uses Van-Laar Model. This mixture presents a positive azeotrope.
Two tanks in are disposed in series. The level of tank 2 must be controlled despite a sine wave disturbance in the flow F3. This is achieved by changing the flow rate F0 of liquid to tank 1. The tanks areas are A1 and A2. Flow equations depends on...
In the present program three methods are used to solve a heat conduction problem. This problem is given in M. N. doOCozisik, Heat Conduction, Wiley, New York, 1980. We use pdepe, short times solution based on analytical inversion of a Laplace...
The program allows one to choose the best reactor setup among three alternatives: (1) a plug flow reactor with recycle, (2) a combination of a plug flow reactor and a stirred tank reactor in series and (3) two stirred tank reactors in series. This... |
