The CHEMCAD suite offers the following products:-

    CHEMCAD represents the basic programme of the CHEMCAD Suite. CHEMCAD is the tool to simulate steady state processes. The flowsheet is created in the user interface of CHEMCAD, the simulation is performed and the results are represented. A library of Unit Operations, which are required to build the flowsheet are provided on a palette.
    The batch distillation process is chosen in applications involving small volumes of complex multi component mixtures. The batch distillation process has some advantages as compared with a continuous rectification but experience is required to achieve an optimum solution. CC-Batch helps the user to reach this objective quickly
    A heat exchanger in CHEMCAD is calculated thermally obtaining important parameters. CC-THERM is the tool to design this heat exchanger. As a result the heat transfer coefficient and the heat transfer area are calculated. Based on the heat exchanger construction data a comparison with the CHEMCAD calculation is obtained. It is possible to optimise the heat exchanger heat
    transfer area automatically by forcing design parameters such as tube length, tube passes, tube layout, shell diameter and baffle design and spacing.
    When studying mass and energy balances the steady state simulation with CHEMCAD is the programme of choice. But, when studying time dependent processes the add-on programme CC-DYNAMICS is the perfect tool to simulate control processes and the behaviour in columns, equipment and reactors. The most important unit operations in CC-DYNAMICS are the dynamic vessel, batch reactor, dynamic column with hold up, PID controller, control valve and ramp controller.
    Complex pipe networks with pump, compressor, turbine, valve, and relief devices based on a CHEMCAD flowsheet. The simulation of safety and relief valves is carried out in accordance with DIERS technology. As a result the mass balance of all streams, their stream direction, physical properties and physical condition are obtained, with two phase streams and their regime being recognised automatically. Several fluid flow models can be chosen for pressure drop calculations. Performance data can be entered for pumps, compressors and turbines allowing the typical performance in plants to be simulated, e.g. pressure drop and mass flow in an isometric pipe system.
    Phase equilibria including VLE (vapour-liquid-equilibrium), LLE (liquid-liquid-equilibrium), SLE (solid-liquid-equilibrium) of multi component mixtures, dew and bubble points, two phase condition, mixture condition, liquid interfaces graphical presentation of binary and ternary phase equilibria, residue curves, and physical properties of multi component mixtures. User components can be added to the data base.
