Software per la simulazione dei processi chimici

PRO/II version 8.3 continues the PRO/II tradition of offering the finest simulation models and tools. Enhancements in all areas of the program are incorporated in this release. Invensys Process Systems continually adds new capabilities. For a summary of defects fixed and other important notices about installation, security and documentation, please refer to the Release Notes for PRO/II 8.3. A sampling of the new features are briefly outlined here.

 Upgrade to SIM4ME Version 3.3 Thermodynamics:

PRO/II has been upgraded to use the most recent version of SIM4ME thermodynamics. Additionally, the updated SIM4ME Thermodynamics has been integrated with TDM, the Thermodynamics Data Manager. This eliminates many inconsistencies between the two products. New features that this development brings to users include the following.

New Correlations for some property calculations

Component Databank cascading

User component data banks now are included in, and selectable from, the standard databank lists in PROVISION.

  SIM4ME Portal Phase II Integration:

Integration of SIM4ME Portal Phase II allows PRO/II to utilize new functionality within the Portal, including:

case studies,

multi- simulation linking, and

assay input information access.

 PROVISION Support for Keyword-only Features

Previously available only through key words, the following features now are fully supported by the Graphical User Interface:

Method-specific component search order: The GUI now supports each thermodynamic METHOD set using its own specific databank search order. Previously, the GUI only allowed the same search order for all METHOD sets in the simulation.

Component-specific databank search order: The PROVISION Graphical User Interface now supports a separate databank search order for each component.

Solids Unit Operations: The PROVISION Graphical User Interface now supports these additional solids-handling unit operations:

Solids Dryer

Rotary Drum Filter

Melter/Freezer

Upstream Unit Operation: Long available only through key words, this unit now is fully supported in PROVISION. This unit provides four different modes of operation that simulate different methods of preparing laboratory and applying it to a simulation. A fifth option, the "Stream Selector", allows changing feeds to a unit in parametric studies.

 Customizable Language Module Infrastructure:

A new infrastructure provides a repeatable process for customizing many PRO/II features to interact with users in local languages other than English. PRO/II features that support this include:

PRO/II error message windows and pop-up (OK/Cancel) windows.

Error and status messages displayed as part of "smart commit" and "cross checks" (that fundamentally come from the same underlying PRO/II error message system).

Main menu bar

Drop-down menus from the main menu bar, and

Right-click (action) menus.

Japanese Language Module Add-on: This module provides Japanese language support for the features listed above.

These enhancements do not enable users to enter descriptive text using local languages.

 Improved Database Containerization - PRZ Enhancements

Several additional types of data files now are saved in the compressed simulation archive (the ".PRZ" file). The newly supported file types include:

".HTRI" files - data files uses to exchange data between an HTRI program and the Rigorous Heat exchanger model in PRO/II.

Pipe Phase files that exchange data between the PipePhase Unit Operation in PRO/II and the PipePhase simulation program.

CapeOpen files used by Cape Open unit operations.

AMSIM data files.

Excel Unit Operation spreadsheets

Property table ".INI" definition and configuration files.

".SLB" (and other) files used for Thermodynamics data serialization

 RATEFRAC® Integration with Electrolytes:

The RATEFRAC® rate-based algorithm now is available within distillation columns that utilize electrolytic thermodynamic systems.

 RATEFRAC® Support for Chemical Reactions:

The RATEFRAC® distillation algorithm now supports reactions within the column based on either equilibrium or non-equilibrium stages.

 CAPE-OPEN Unit Operation Enhancements:

PRO/II has been enhanced to access real parameters exposed by CAPE-OPEN unit operations. Refer to Cape-Open Compliance report -3.10.1 (available at the Co-Lan internet web site).

Real (double precision, floating point) parameters exposed by CAPE-OPEN unit operations now are accessible to the Spec/Vary system in PRO/II. This makes them available for use in the Controller, MVC, Optimizer, and Case Study.

 HTRI/HXRIG Interface Improvements:

The HTRI-HXRIG Interface offers improvements in the following ways:

Improved speed of execution of the HTRI-HXRIG interface

The HTRI interface now supports use as a Thermosiphon

Phase change points now are allowed in the property grid. Originally implemented in the  HEXTRAN-HTRI interface, this and other enhancements now are available in PRO/II.

Latent heat data now is included in the data exchanged between PRO/II and the HTRI dll.

 Residual Curve Map Utility Included in the Standard PRO/II install:

This example application is able to calculate and display ternary mixture properties and simulation-results of ternary-system processes.

 Utility Stream Option Added to the ACE

The air side of the Air Cooled Exchanger now provides an option to model air flow as a utility stream. This eliminates the need to define a process stream to model air.

 Changed Default Settings of Various Options

The default settings of several options have changed with this version of PRO/II. None of the options affect the calculation results, although some output report options are different. The following defaults are changed.

BK10 removed from the list of "Most Commonly Used" thermodynamic methods.

SRKM added to the list of "Most Commonly Used" thermodynamic methods.

New Output Report Defaults:

”r;Include Thermodynamic Input Parameters” now is turned "ON" by default.

”r;Include Overall Flowsheet Mass Balance” now is turned "ON" by default.

”r;Print Calculation Sequence Map in the Output"’ now is turned "ON" by default.

 Improved Column Behavior in Recycles & Restarts Skipped

Previously, distillation columns in recycle loops recalculated in every recycle iteration. Now, improved logic tests a solved column to determine if it needs to resolve. When no changes are detected in the feeds, column operating conditions, or options, nothing affects the solution. In each iteration where this is found, the column calculations are skipped so they are not repeated.

Previously, restarting a solved column began calculations at the solved state.  In many cases, the results drifted due to the different starting point. Now, restarted columns always restart using original initial conditions. This eliminates any drift in results in most cases.

 Selecting Components From User-Defined Libraries

Previously, user-defined component data libraries were not included in lists of available libraries and could not be selected from those lists. User libraries were constrained to keywords only. Now, user libraries are visible in the Component Selection &endash; List/Search window.

Specifically, user libraries are available in the Component Family list, along with the system libraries SIMSCI and PROCESS, and other component groupings.

 Support for 64 bit Operating Systems

 Update Initial Estimates for MVC, Optimizer, and Other Controllers

PRO/II 8.2.2 Enhancements

 Aromatics extraction NRTL library for use with the Sulfolane® BTX extraction process.

 (Sulfolane is a trademark of Shell International) .

 A new NRTL parameter databank containing literature sourced interaction parameters for 11 components have been added to the thermotynamics library. All binary combinations are available. The components include:
