1), Simulis ® Thermodynamics allows a client application to calculate properties and phase equilibrium using an external CAPE-OPEN thermodynamic property package coming, for example, from Aspen Properties (AspenTech), PPDS (TUV-NEL), Multiflash (Infochem). On the one hand, throughout its ?socket? facility (Fig.

Simulis ® Thermodynamics and CAPE-OPENĮven if the Simulis ® Thermodynamics architecture is not based, in native, on CAPE-OPEN standard (mainly for keeping existing codes), Simulis ® Thermodynamics proposes a complete interoperability with other software implementing the CAPE-OPEN standard. Benedict-Webb-Rubin modified Starling (BWRS),.Simulis ® Thermodynamics model library contains the most used and relevant models as shown in the following non exhaustive list: Liquid - Vapor (TP, HP, SP, wT, wP, UV, ?).Pseudo critical properties (T c, P c, V c, Z c).Īnd to perform the following phase equilibrium calculations:.Compressibility properties (Z, C p/C v, ?).Simulis ® Thermodynamics is able to calculate the following properties and their derivatives (wrt temperature, pressure, number of moles): It is based on well-known ProSim thermodynamic calculation library which has been validated through many years of intensive industrial use. Simulis ® Thermodynamics is a thermodynamic properties and phase equilibrium calculation server for pure compounds and mixtures (containing up to 200 simultaneous compounds). In the future, other components will be developped and will deal with chemical reactions and unit operations.
The last software component, called Simulis ® Thermodynamics, is presented in this paper through its use as a toolbox within MATLAB ®. A pure compound property database, containing more than 1700 compounds, is provided with this software component. Properties can be constant or temperature dependent. Next, Simulis ® Properties, is a pure compound properties server.
The first one, called Simulis ® Conversions, allows to manage quantities and unit conversion in an application. Today, three software components are already available. The CAPE-OPEN standard accompanies that trend by providing a common interface specification for process simulation software.Ĭonsidering this situation, ProSim decided to change the architecture of its tools to answer not only its own customers' expectations, but also the whole simulation process software user community. New technologies based on software components developed with object-oriented languages are available to meet this new market requirement. In addition to the performance and user-friendliness criteria, the various tools must enable substitution one to another and exchange of services: they must be interoperable and integrable. Usage is again disturbed today by computer networks and co-operative work. Throughout their history, process simulation tools had to adapt to the evolutionary nature of hardware and software technologies and to an increasingly demanding market.
