10 OUTLINE Simulis Thermodynamics overview Its different levels of use Within Microsoft EXCEL Integrated in other codes As a framework to develop new thermodynamic models or to welcome existing ones Concluding remarks
11 WITHIN MICROSOFT EXCEL Thermodynamic functions are added to Microsoft Excel and used in spreadsheets as native Excel functions to perform more or less complex engineering calculations but with rigorous thermodynamics
12 EXAMPLE OF A MCCABE & THIELE METHOD FOR BINARY DISTILLATION IN EXCEL
13 OUTLINE Simulis Thermodynamics overview Its different levels of use Within Microsoft EXCEL Integrated in other codes As a framework to develop new thermodynamic models or to welcome existing ones Concluding remarks
14 SEAMLESS INTEGRATION IN ANY CODE Thanks to its component based architecture, Simulis Thermodynamics can be easily embedded in any application that supports the COM/DCOM technology: Visual Basic or VBA (Microsoft Excel) MATLAB C++ Delphi FORTRAN C# etc However, the interface between the embedding application and Simulis Thermodynamics must be coded
15 CO THERMODYNAMIC SOCKET Ability to use an external thermodynamic model (CAPE-OPEN "Property Package") Successfully tested with Multiflash (Infochem) PPDS (TUV-NEL) Aspen Properties (AspenTech) Implementation Thermo 1.0 Thermo 1.1 (Nov. 2007) COM Thermo (AspenTech) IVCSEPThermoSystem (IVC-SEP) COCO TEA (AmsterCHEM), etc External software able to generate CO packages (Aspen Properties, Multiflash, PPDS, ) External CAPE-OPEN Property Package Simulis Thermodynamics Client Software MS-Excel ProSimPlus, MATLAB, etc If required, a third party thermo package can be used within any application embedding Simulis Thermodynamics
16 CO THERMODYNAMIC PLUG Ability to generate CAPE-OPEN "Property Packages" to be used within compliant modeling tools Implementation Thermo 1.0 Thermo 1.1 (Nov. 2007) Client Software Microsoft Excel ProSimPlus, MATLAB, etc Simulis Thermodynamics Successfully tested in Aspen Plus (2004 and v12.1) Aspen Hysys (2004 and v3.2) PRO/II (v7.1) gproms Xist (HTRI) UNISIM Design etc CO Property Package generated by Simulis Thermodynamics Modeling tool implementing CO Thermo Socket (AspenPlus, HTRI, ProSimPlus, etc) The thermo of ProSim can be used in software without satisfactory thermo routines A thermo expert can prepare with Simulis Thermodynamics the model for a complex system, and provide it to its colleagues for further "safe" use in their traditional simulation tool (AspenPlus, ProSimPlus, )
17 IMPLEMENTS THE STANDARDIZED CAPE-OPEN INTERFACES Any application that embeds Simulis Thermodynamics automatically inherits from its CAPE-OPEN standard compliance Seamless integration of Simulis Thermodynamics in many codes is allowed
18 INTEGRATION IN PROSIMPLUS Thermodynamics Chemical Reactions Unit Operations Numerical Methods GUI Conventional simulator Monolithic program (generally divided into several source files and DLLs) ProSimPlus Thermodynamic calculations are performed within a component (Simulis Thermodynamics) This component implements CAPE-OPEN interfaces (Plug & Socket) ProSimPlus also implements CO Unit Socket Thermodynamics Simulis Thermodynamics Unit Operations Chemical Reactions GUI Numerical Methods
19 OUTLINE Simulis Thermodynamics overview Its different levels of use Within Microsoft EXCEL Integrated in other codes As a framework to develop new thermodynamic models or to welcome existing ones Concluding remarks
20 THE "EXPERT MODE" For users who want: to develop their own new thermodynamic models or to integrate in Simulis Thermodynamics exiting models taking advantage of Simulis Thermodynamics environment (pure components properties, unit conversions and management, ) in view to use these developments in other applications (commercial software, Excel, legacy codes, ) Two possibilities are offered: 1. VBScript models 2. External DLL models
21 VBSCRIPT MODELS Code is directly entered in Simulis Thermodynamics A skeleton is provided Many available functions Function parameters must satisfy a predefined syntax (name, type)
22 EXTERNAL DLL MODELS An external DLL is plugged User parameters are supported Many available functions Function parameters must satisfy a predefined syntax (name, type)
23 VBSCRIPT MODELS VS DLL MODELS VBScript models: Interpreted language not very efficient Useful for prototyping or simple functions (Cp, ) Can be a first step DLL models: Can be built using any language (FORTRAN, C++, ) Allows re-use of existing codes (with some modifications) More efficient In both cases access to pure component properties, units management,
24 THE "EXPERT MODE" VBScript, external DLL and native models can be mixed (each one computing a different property) Priorities must be given Native models will be used except when a VBScript model or a DLL model is available
25 THE "EXPERT MODE" Combination of VBScript, external DLL and native models is supported User DLL for calculation of H and Cp H (Cp) Cp H (Cp) Native DLL for calculation of H and Cp H (Cp) Cp H (Cp) However, no "true re-entrance" between different modes
26 THE "EXPERT MODE" Both VBScript and external DLL models can be used in CAPE-OPEN thermodynamic packages built with Simulis Thermodynamics "Expert Mode" of Simulis Thermodynamics vs CAPE- OPEN Thermo Wizard Easy configuration (access to standard pure components databases, ) Predefined access to pure components properties User-friendly existing GUIs to access parameters Full rewriting is not required (possibility to mix with native existing models)
27 CONCLUDING REMARKS Simulis Thermodynamics allows several levels of use Within Microsoft Excel to perform more or less complex engineering calculations Embedded in other applications taking advantage of the CAPE-OPEN standard interfaces implemented (plug & socket) As a framework to welcome existing thermodynamic models or to develop new ones in view to use them in other applications ("Expert Mode")
28 CONCLUDING REMARKS These levels of use can coexist in the same organization allowing: Minimization of learning time Consistency of data & results between several applications Reusability of available expertise Permanence of internal knowledge The "Expert Mode" of Simulis Thermodynamics can be an alternative to CO Thermo Wizard in order to make thermo legacy codes CAPE-OPEN compliant No knowledge of CAPE OPEN technology required Reduced development time
