What can I do with CC-API?

CC-API offers 4 ways to interface with CHEMCAD.

Connect standard software to CHEMCAD. This way, another application can use CHEMCAD's thermodynamic calculations, i.e. access property data and thermodynamic models.

Embed CHEMCAD in your application. Your application can be written in C# or it can be based on WordPress, MATLAB, or LabVIEW.

Extend CHEMCAD with custom unit operations. Your expertise and know-how can be converted into a model that is used in process design and optimization. Or you can get an innovative unit op from our shop.

Operate CHEMCAD in the cloud. We have developed some applications that demonstrate the unique advantages of cloud computing. Check out our Lab here.


What's in the CC-API toolbox?

.NET Interface

.NET Interface is the center piece of CC-API. It is a class library and an object model to access parameters in a CHEMCAD flowsheet.

CHEMCAD flowsheets contain unit operations, streams and physical properties. These objects have many parameters. With .NET Interface you can read any of these parameters, change their values, and write them back to the flowsheet.

UnitOps & Add-on Manager

Custom add-ons extend the CHEMCAD functionality.

Our Add-on Manager administers DLL files for any number of unitops, enthalpy models, k value models, pipe models, or kinetic reaction rates.

You can get these from our shop or from anyone who specializes in programming DLL files.

Read more about Add-on Manager here, download Add-on Manager here, or visit our shop of CHEMCAD UnitOps.


We develop applications based on .NET Interface.

Before they reach production status, we deploy them in the Lab(oratory) for demonstration and use by selected customers.
