- Reaction Equilibrium
- License: Shareware

Reaction Equilibrium designed as a small and simple simulation tool that manages to illustrate qualitative concepts relating to chemical reaction equilibrium.
Problems in reaction equilibria are a staple of physical chemistry and thermodynamics courses, and their treatment via the formalism of the equilibrium constant is familiar to anyone with training in chemistry or chemical engineering.
While the use of these tools is not difficult to learn, an intuitive understanding of the standard Gibbs energy, enthalpy, and entropy of reaction can be more elusive.
Like everything in thermodynamics, they have their origin in molecular-level behaviors, and thus some understanding of them can be gained by observing molecules "react" while following Newtonian mechanics, and seeing how the emergent behavior can be...

- Hunter and Nash Graphical Equilibrium Stage Method
- License: Freeware
- Price: 0.00

The program computes the tie lines, the operating and mixing points and the number of equilibrium stages using the Hunter and Nash graphical method of a liquid-liquid extraction problem. One feed of acetic acid (35 wt %) in water which flow rate = 1000 kg/hr is extracted using a solvent consisting of pure isopropyl ether which flow rate = 1475 kg/h. We find that 5.35 equilibrium stages are needed to achieve the raffinate product requirement of 10 wt % acetic acid composition. This example is treated in the book by Phillip C. Wankat, Separations in Chemical Engineering, Equilibrium Staged Separations, Prentice Hall, 1988.

- VAPOUR LIQUID EQUILIBRIUM P-T-x-y CALCULATIONS FOR A IDEAL BINARY MIXTURE
- License: Freeware
- Price: 0.00

This being a very basic program for the demonstration of bubble and dew point calculations of a ideal binary VLE mixture obeying Raoult's. The basic purpose of this program is to demonstrate VLE P-T-x-y calculations of a ideal binary mixture and to get related data in graphical form for any such a system. It uses Raoult's law for the VLE calculations, the Antoine equation for the calculation of pure component vapour pressures at different temperatures and the Dalton's law for the calculation of total pressure of the vapor in equilibrium with the liquid. Further modifications required are: 1)It can be modified further for non-ideal mixtures by introducing the activity coefficients of the components.

- Vapor-Liquid Equilibrium Diagram of Ethane-Benzene at 25dlT-C and 175dlT-C
- License: Freeware
- Price: 0.00

The programs compute the vapor-liquid diagram of an ethane-benzene mixture at 25dlT-C and 175dlT-C. This binary mixture exhibits a peculiar behavior because the volatilities of ethane and benzene are very different. We use the SRK equation of state to compute equilibrium constants. This problem was presented in Thermodynamique, Application au GdoTenie Chimique et doT l'Industrie PdoTetrolidodure by Jean Vidal, Technip, 1997..

In the program, we obtain equilibrium constants, compressibility factors, molar volumes and densities using the Soave-Redlich-Kwong equation of state. We find the same results as those given by Henley and Seader in Equilibrium-Stage Separation Operations in Chemical Engineering, Wiley, 1981 (example 4-10 page 175).

- Real Option Valuation
- License: Shareware
- Price: 26.00

The Real Option Valuation template combines a set of option pricing tools to quantify the embedded strategic value for a range of financial analysis and investment scenarios. Traditional discounted cash flow investment analysis will only accept an investment if the returns on the project exceed the hurdle cost of capital rate. This is a worthwhile exercise as input for valuing real options; however it ignores any strategic options that are commonly associated with many investment decisions. Real option valuation provides the ability to identify what options might exist in a business proposal and the tools to estimate the quantification of them.
