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 though the snippet would work without it.

%Read the temperature of three streams from your CHEMCAD
%flowsheet "Flash.cc7" using CCAPI

try
%Path to load the CCAPI DLL interface with CHEMCAD
asmInfo = NET.addAssembly('...\...\CGC.CC-API.dll');

%Put your .NET Interface key here
license_key='.......'

%Starting CHEMCAD Server
chemcad = CCAPI.Server(license_key);

%Path to the CHEMCAD flowsheet
path='...\..\Flash.cc7';

%Load the CHEMCAD flowsheet from the specified path

chemcad.LoadFlowsheet(path);
flowsheet=chemcad.CurrentFlowsheet;

%Reading Streamd Data from CHEMCAD flowsheet
streamsCollection=flowsheet.StreamsInCurUnits;

%First stream in the CHEMCAD flowhseet

streamFirst=streamsCollection.GetStreamAt(0);

%Second stream in CHEMCAD flowhseet

streamSecond=streamsCollection.GetStreamAt(1);

%Third stream in CHEMCAD flowhseet

streamThird=streamsCollection.GetStreamAt(2);

%Reading the streams temperature from CHEMCAD flowsheet
%and displaying on MATLAB command widnow

firstStreamTemp=streamFirst.Temperature
secondStreamTemp=streamSecond.Temperature
thidStreamTemp=streamThird.Temperature

%Relasing the COM Object
%and set the CHEMCAD objects to zero

chemcad.Release;
chemcad=0;
asmInfo=0;
flowsheet=0;

 %Exception handling and release CHEMCAD objects
catch e 
   e.message
      if(isa(e,'NET.NetException'))
        e.ExceptionObject
        chemcad.Release;
        chemcad=0;
        asmInfo=0;
        flowsheet=0;
      end
end
