What does SysCAD do?

SysCAD is a powerful and versatile plant simulator that can be used to simulate the simplest processing circuit through to complex full plant operations.

  • General Applications
    1. Process Design
    2. Mass and Energy Balance
    3. Evaluate Alternate Flowsheets
    4. Process Optimisation
    5. Process Understanding
    6. Training of Plant Engineers
    7. Production Loss Reporting
    8. Research and Development
  • Dynamic Applications
    1. Plant Design
    2. Equipment Sizing
    3. Process Control Strategy Design
    4. Control System Testing
    5. Operator Training
    6. Production Planning
    7. Surge & Availability Studies

For more information, please see Applications and Features

How does SysCAD Work?

A brief description of the SysCAD workflow is as follows:

  1. A project configuration file is set up with a set of user defined chemical compounds (done via SysCAD Database and configuration file.)
  2. A process flowsheet is created by inserting “Process Units” onto the Graphics Window. These process units are then linked together with Pipes
  3. SysCAD Process Units may include:
  4. When solving a SysCAD project, the SysCAD solver will build and solve a network of simultaneous equations internally. Users only need to supply information such as:
    • Feeder information such as Feed rate, Temperature, Pressure and Composition. This is done through the Access Window, which can be viewed by right clicking on the unit operations.
    • Configuration information of each Process Unit operation, such as reactions, mass separation, heat transfer, etc.
    • Various controls to set constraints and/or set-points in the project.
    • SysCAD can handle any number of complex recycle streams within a project.
  5. When a project is solved, mass and energy will be balanced at each process unit and node point in the project.
  6. SysCAD results can be reported using MS Excel for analysis.

What Solver mode and Add-ons does SysCAD have?

SysCAD is offered in two main solver modes (Steady State (ProBal) and Dynamic Transfer) with a number of optional add-ons.

  • The solver modes include a number of standard models
  • Both SysCAD solver modes will perform mass balance calculations.
  • To include any energy calculations the Energy Balance add-on is required.

SysCAD has a number of industry specific add-ons, some examples are:

  • Alumina Add-on
  • Potash Add-on
  • Sugar Add-on
  • Size Distribution Add-on

SysCAD can also be integrated with various 3rd party thermodynamic calculation engines and databases, currently these include:

Please see SysCAD Structure for more information on the various add-ons available in SysCAD.
Please see Models for detailed SysCAD models documentation.

Is Training required to use SysCAD?

It is strongly recommended that new users budget for some form of SysCAD training, as it has proven the most time and cost effective method of learning to use the software effectively.

KWA Kenwalt Australia (the owners and developers of the SysCAD software) offer formal and informal SysCAD training courses on an as needed basis.

The different types of training offered and course content are discussed in Training. Please contact us for pricing information or to discuss your individual needs.

Is self-help tutorial available?

To help new SysCAD users, a number of Tutorial documents and projects are available to demonstrate the many features and functionality in the SysCAD software.

  • These Tutorial documents and projects are discussed in Tutorial Overview.
  • Some Tutorial Videos are available here. The user can refer to these for quick demonstrations of selected SysCAD features/functions.

Are there Example Projects available?

A number of example projects are distributed with the SysCAD software. These have been created to show various different features of SysCAD in an actual project as well as its use in different industries.

Please see Example Projects for more information.
