Flowsheet symbol standardization has been developed by various professional and technical organizations for their particular fields. As a direct companion of the completed flowsheet, the line schedule sheet transmits the process and mechanically necessary details for proper interpretation of the piping aspects of the flowsheet.

2. Flowsheet modelling and design through process-groups. To apply a group contribution method for flowsheet synthesis, design and modelling the following has been developed: rules for process-group representation of flowsheets, a "property" model for separation process flowsheets and a reverse-approach based method for …
