Interfacing CHEMCAD
MathWorks developed MATLAB, a proprietary programming language. It allows matrix manipulations, plotting of functions and data, implementation of algorithms, and creation of user interfaces. In addition, it allows interfacing with programs written in other languages, including C, C++, C#, Java, Fortran and Python.
Use the CC-API .NET class library and object model in MATLAB to write to and to read from a CHEMCAD flowsheet.
For example, a program can carry out these tasks:
The code snippets on this page show how to write to and how to read from a CHEMCAD flowsheet.

Performance of an absorber also depends on the number of the segments. To visualize the effect of change of number of segments on concentration profiles in CHEMCAD is difficult and slow procedure. Following code snippet shows how to change the … Read More
Many tasks in the chemical industry require the physical properties of chemical components. Properties are molecular weight, density, critical pressure and more. The calculation mixture properties, e.g. specific heat capacity, vapor viscosity, thermal conductivity and many more require these properties. … Read More
The main content of a CHEMCAD flowsheet are unit operations and streams. MATLAB can be used to optimize a process in a flowsheet. For this, MATLAB has to access any parameter in the flowsheet. This code snippet demonstrates how to … Read More
A separation unit operation in MATLAB requires thermodynamic properties and models. This unit operation and many other unit operations in the chemical industry require VLE calculations. CHEMCAD provides VLE data. CHEMCAD has several built-in thermodynamic models, e.g. NRTL, Wilson, UNIFAC, UNIQUAC, … Read More
Read distillation column hydraulics using MATLAB Distillation is one of the most studied unit operations in terms of optimization and control. One way to optimize a distillation column is to find the optimal feed stage. Another way is to tune the … Read More
Binary interaction parameters and MATLAB Vapor liquid equilibrium (VLE) thermodynamic models use binary interaction parameters (BIPs) to determine thermodynamic behavior. CHEMCAD can only use either VLE or LLE to calculate binary interaction parameters. The prediction can be improved using a … Read More
Any CHEMCAD flowsheet optimization in MATLAB requires reading data from the flowsheet. The code snippet aims to be the shortest possible snippet to demonstrate how MATLAB accesses a CHEMCAD flowsheet. We recommend to include an exception handling routine, even … Read More
