Cycad Process®

(version 2017.05)
• Fix where some saved files wouldn’t load; and
• Other minor tweaks.

What is Cycad Process®?
Cycad Process® combines process simulation with sophisticated drawing capabilities to produce detailed engineering diagrams and reports. The package allows you to draw the process flow diagram or process block diagram and calculate the mass and energy balance.


  • Industries

    Cycad Process® can and has been used to model most processes in mineral industries.
  • Interface

    Full graphical interface conforming to typical Windows standards, Drag-and-drop interface, Extensive library of process units, Properties entered through an intuitive
  • Steady-state simulations

    Sequential modular approach to simulations, Intelligent, automatic calculation of recycle streams to minimize solution time, No ordering of the process
  • Calculations

    Large library of calculation based on published solution methods, Energy balance integrated with all calculations, Direct correspondence between the plant,
  • Component data

    Extensive component database with physical and basic thermodynamic data, Can easily add user-specified components, Can export and import components from
  • Scripting

    Can script your own process unit, Uses C# language for scripting, Can access many internal functions/methods, Can reference all properties
  • Extensive reaction options available

    Extent/conversion-based reactions, Rate-based (liquid or gas phases), Gas mass transfer, Shrinking particle/core models, 2D-shrinking core model.
  • Particle size distributions

    Cycad Process® can track and calculate the changes in particle sizes in processes such as milling and leaching.
  • Designers

    Designers are used to target process unit outputs and sometimes referred to as ‘controllers’, Unit-specific and flowsheet (general) designers are
  • Outputs

    Engineering quality drawings, Block flow diagrams, Process flow diagrams, P&I diagrams currently under development.
  • Compare

    Comparing results between different versions or calculations can be difficult and time consuming for even a relatively small balance. Cycad
  • Parameter estimation

    Uses Levenberg–Marquardt algorithm to fit parameters, Can be used to fit most process unit parameters using measured data.


  • How do I register my installation of Cycad Process®?

    1. Click on the “Register” button from the ‘Home’ tab.
    2. Copy and email the computer ID to cycadprocess(at)
    3. A registration key will be sent back to you.
    4. Copy and paste this registration key into the registration textbox and click ‘Register Install’.
    5. After a few seconds you will get a message saying registration complete, restart Cycad Process to access the full functionality.

  • How do I add a process stream?

    1. From the ‘Setup Balance’ tab select the ‘Process stream tool’ (between ‘View distributions’ and ‘Site Conditions’).
    2. Then connect units by left-clicking down where you wish the stream to begin and dragging to where you wish the stream to stop. Release the left-click for the stream to be finalized.
    3. Streams should start from a process unit (or feed flag) and end at another process unit (or product flag).
    4. Streams that are correctly connected to process units (or flags) will have red connection points – unconnected ends will show as white connection points.

  • How do I add a page?

    From the ‘Home’ tab select the “Add Page” or “Insert Page” buttons.

  • How do I print?

    1. Select the ‘File’ tab.
    2. Select “Print Flowsheet” to print the diagram, or,
    3. Select the “Print Report” to print one of the reports Cycad Process® generates.

  • How do I set the altitude for my project?

    From the ‘Setup Balance’ tab press the “Site Conditions” button.

  • How do I see what is in my stream?

    1. Select the stream you wish to view and then go to the Stream Manager window.
    2. To open the Stream Manager window press the “Stream Manager” button from the ‘Setup Balance’ tab.
    3. Other streams can be viewed by returning to the Flowsheet page and selecting that different stream and going back to the Stream Manager window.
    4. The Stream Manager window can be docked anywhere the user chooses by right-clicking on the heading and selecting “Floating”.
