INTRODUCTION
CHEMCAD 5 offers three approaches to link with Visual Basic applications or other Windows
applications. In the first approach CHEMCAD 5 is activated as an out-of-process server from a
Visual Basic application. This enables a VBA application, such as Excel macros, to delegate
computational tasks to CHEMCAD 5 running in background. The second approach functions
through the addition of a new unit operation in CHEMCAD 5 called “Excel Unit”. With this unit
operation, a user can program specific tasks in VBA macros within an Excel workbook, and
CHEMCAD 5 can execute these macros in the context of a unit operation during a simulation run.
The third approach facilitates user-specified rate expressions in use with CHEMCAD 5 built-in
kinetic reactor (KREA) and batch reactor (BREA).
CHEMCAD 5.x publishes a set of COM interfaces to two type libraries, cc5.tlb and ccx2xls.tlb.
Through these interfaces, many CHEMCAD 5.x functions and data are made available to other
Windows applications. By executing the interface methods, a user can retrieve flowsheet topology
and its unit operations, update stream data and unit operation parameters, calculate k-values and
enthalpy, flash streams and convert engineering…
