(344e) Cape-Open Implementation in Chemcad: Thermo Property Package Sockets, Integrated Pmc Generator, and Unit Operation Socket

This paper presents the implementation of CAPE-OPEN interfaces in the powerful process simulation suite, CHEMCAD. Examples of interoperability with CAPE-OPEN PMC's will be given.

The implementation of CAPE-OPEN Thermodynamic and physical property interface enables CHEMCAD users to access third party CAPE-OPEN thermo property packages within CHEMCAD with only a few mouse clicks. The implementation includes the equilibrium flash routine, K-values, log-fugacity coefficient, fugacity-coefficient and many other basic thermo or physical property routines. A log tool is included for tracing all calls to a package.

The integrated PMC generator in CHEMCAD enables users to generate CAPE-OPEN compliant Thermo property package easily from any of the large number of thermodynamic models and chemical components built into the program. Best of all, an entire process simulation environment is available, which includes tools for generating, plotting, and regressing equilibrium data, enabling fast and easy determination of optimal thermodynamic model(s) for a chosen system.

Using CAPE-OPEN unit operations in CHEMCAD is also designed to be intuitive. The user's interaction with these unit operations follows the familiar interface of native CHEMCAD unit operations. The selection, configuration, and use of CAPE-OPEN unit operations conforms to the same interface styles that CHEMCAD uses. Output from CAPE-OPEN operations fits into existing flow sheet reporting tools. CAPE-OPEN unit operations integrate into CHEMCAD's sequential, simultaneous, and dynamic calculation modes.
