DWSIM Calculator

DWSIM Calculator is an app to calculate Phase Equilibria, properties of mixtures of substances (compounds) and Unit Operation models using advanced thermodynamics. Based on the model library of DWSIM, an award-winning open-source process simulator for desktops, DWSIM Calculator for iOS features:

- An intuitive interface for desktop process simulator users;

- Experimental data for more than 400 compounds;

- 6 calculation modes: Single Compound Properties, VLE/VLLE Phase Equilibria, True Critical Point, Phase Envelope, T-x-y and P-x-y Binary Envelopes;

- 7 thermodynamic model sets: Peng-Robinson and Soave-Redlich-Kwong Equations of State, NRTL, UNIQUAC, Modified UNIFAC (Dortmund), Raoult's Law and IAPWS-IF97 Steam Tables;

- 3 state specifications: Temperature/Pressure, Temperature/Vapor Fraction and Pressure/Vapor Fraction;

- Phase properties: Enthalpy, Entropy, Compressibility Factor, Density, Molecular Weight, Heat Capacity, Thermal Conductivity and Viscosity;

- Single-compound properties: Critical Parameters, Acentric Factor, Chemical formula, Structure formula, CAS Registry Number, Boiling Point Temperature, Vapor Pressure, Heat of Vaporization, Ideal gas Enthalpy, Ideal gas Enthalpy of Formation at 25 C, Ideal Gas Gibbs Free Energy of Formation at 25 C, Ideal Gas Entropy, Heat Capacity Cp, Ideal Gas Heat Capacity, Liquid Heat Capacity, Solid Heat Capacity, Heat Capacity Cv, Liquid Viscosity, Vapor Viscosity, Liquid Thermal Conductivity, Vapor Thermal Conductivity, Solid Density, Liquid Density and Molecular Weight;

- Unit Operation calculation models: Valve, Heater/Cooler, Pump, Compressor/Expander, Heat Exchanger, Gas-Liquid Separator.

The calculation results can be viewed in text reports or charts. Reports can be shared as plain text (send as message, email, publish on facebook, etc) and charts can be shared as PDF or PNG files.
