‘"Designed to bring the same ease of use to flowsheet drawing and solution that word processors bring to the preparation of text based documents."


Process flowsheets built into a spreadsheet:

  • Rapid sketching of report quality flowsheets using a ‘flowsheet aware’ drawing package
  • Extensive process unit icon library
  • Block diagram option
  • Easy addition of user drawn custom icons
  • Data are stored totally within the spreadsheet - no additional files
  • All data are accessible to the user - no internal data formats
  • WYSIWIG presentation - may be used in conjunction with other tools for the Microsoft® WindowsTM operating system.



The flowsheet makes an ideal vehicle for:


  • Presentation of survey results
  • Communication of design data
  • Preparation of design data
  • Display of process balance data



The Limn:Solve ‘Simulation Engine’ provides:

  • Balanced flowsheet solutions using your spreadsheet models, the Limn model pack, or model packs from external sources. 
  • Spreadsheet based simulation (without circular references!).
  • Results of simulations saved within the spreadsheet and presented in data blocks on the flowsheet.


Limn may be further enhanced by the addition of domain specific Add-Ins:

  • WizardPack Add-On for LimnProvides data structures and models for simulation and analysis of mineral, coal and other processing operations


  • THERMO Add-In for Limn and Excel –Provides simple spreadsheet access to a chemical thermodynamics database and calculations
