Many additional models as PC-SAFT etc. are available on request, contact Prode for details. Prode Properties includes : Selectable units of measurement; Procedure for fitting BIP to measured VLE / LLE data points (data regression); Procedure for fitting BIP to VLE values calculated with UNIFAC; Functions for simulating operating blocks (mixer, gas separator, liquid separator); Functions for accessing component data in database (the user can define mixing rules); vapor-liquid-solid fugacity plus derivatives vs. temperature pressure composition; vapor-liquid-solid enthalpy plus derivatives vs. temperature pressure composition; vapor-liquid-solid entropy plus derivatives vs. temperature pressure composition; vapor-liquid-solid molar volume plus derivatives vs. temperature pressure composition; Flash at Bubble and Dew point specifications and P (or T); Flash at given temperature (T) and pressure (P) multiphase vapor-liquid-solid; Flash at given liquid fraction (vaporization ratio) and P (or T); Flash at given enthalpy (H) and P multiphase vapor-liquid-solid; Flash at given entropy (S) and P multiphase vapor-liquid-solid; Rigorous (True) critical point plus Cricondentherm and Cricondenbar; vapor-liquid-solid density; vapor-liquid Isobaric specific heat (Cp) and Isochoric specific heat (Cv) plus cp/cv; Gas heating value; Gas Wobbe index; Gas Specific gravity; vapor-liquid Joule Thomson coefficients; vapor-liquid Isothermal compressibility; vapor-liquid Speed of sound; vapor-liquid Viscosity; vapor-liquid Thermal conductivity; vapor compressibility factor; liquid Surface tension; http://www.prode.com/en/pppopc.htm http://www.prode.com/en/pppopc.htm Prode Properties includes a OPC client interface, you can connect your OPC server, set (in real-time) compositions and operating conditions (from a Gas Chromatograph or any OPC server unit) and get immediately all the properties which you need. The OPC interface exports more than 30 different properties including critical pressure, temperature, CricondenBar, CricondenTherm, speed of sound, Joule-Thomson... http://www.prode.com/en/hed.htm http://www.prode.com/en/hed.htm Prode HED provides a simple and effective way for the thermal design and rating of shell and tube heat exchangers, Prode HED analyses all the common heat exchangers processes including : Sensible heat, both liquid and vapor; Forced circulation evaporators; Horizontal and vertical condensers; Falling film evaporators; Prode HED is a C++ Windows application developed by Prode, the interface features graphing capabilities, easy editing and choice of different units of measurement. Prode HED works alongside Prode PPP to predict fluid properties and heat curves for a wide range of pure fluids and mixtures. Prode PPP comprehensive thermodynamic models in union with zone analysis provide a great flexibility, the user is also allowed to specify directly fluid properties. Fluid properties may be specified directly by the user or calculated with Prode PPP. Rigorous heat curves with Prode PPP; Multizone analysis; Prode HED does multizone analysis via stepwise calculations, different combinations of heat transfer models are allowed: Single phase fluids in laminar, transition or turbulent flow regime; Boiling of liquids; Condensation of vapors; Prode HED can handle several different configurations: TEMA type designations for front end, shell and rear end; Single, double and triple segmental baffles; Tube layout may be 30 or 60 degree triangular, 45 or 90 degree square; Prode HED produces a detailed report including: Properties of mixture including VLE (multizone analysis); Comprehensive information on shellside and tubeside heat transfer coefficents; Tema data sheet; http://www.prode.com/en/valves.htm http://www.prode.com/en/valves.htm Prode Valves is an example of custom software application, Prode Valves can assist in design, rating and selection of control, safety, relief valves, in addition to procedures for rigorous design and rating Prode Valves offers the benefit to automatically identify the most suitable product and fills in all detailing specifications...
