Release date: January 12, 2009

This new release includes a number of extension and improvements of the Windows Interface and Simulation Engine. Most important are listed hereunder.

Windows Interface

-   View of external links - To view data relations between Unit Operations and Logical Operations
-   Graph drawing has been completely changed and updated - Data export to Excel available
-   Heat and material balance view added. To browse all stream results in one view
-   Notes and Remarks feature completeted. User can add notes and remarks to his problem

Simulation Engine

-   Distillation column simulation extended to an unlimited number of trays
-   Chemical reaction available for vessel depressurization to simulate fugitive reactions
-   Continuous feed and drawoff feature added to vessel depressurization to simulate HIPPS actions
-   A new correlation (2FLUIDM) for two-phase flow in pipelines is now available - see next paragraph for more details
-   Erosional velocity calculation (API RP14E) available in PIPELINE units
-   New graphs generated from pipeline simulations for easier flow assurance analysis

2FLUIDM - Two Fluid Model

This new correlation has been developed on the basis of latest publications about multiphase flow in pipes
It incorporates both mechanistic two-fluid and drift-flux models. It supplements existing correlations and can be used for steady state calculations of multiphase flows in pipelines for horizontal, inclined and vertical configurations.
