This capability allows users to work on their projects anytime and anywhere, making it a convenient tool for chemical process simulation. The app includes a touch-enabled process flowsheet diagram (PFD) drawing interface, which is hardware-accelerated and supports touch input. This feature enables chemical engineers to build complex process models with ease and efficiency.

DWSIM is equipped with advanced thermodynamic models, including VLE (Vapor-Liquid Equilibrium), VLLE (Vapor-Liquid-Liquid Equilibrium), and SVLE (Solid-Vapor-Liquid Equilibrium) calculations. Users can calculate fluid properties and phase distributions using various Equation of State and Activity Coefficient models. The app supports a comprehensive compound database, providing extensive data for over 1200 compounds that can be utilized in simulations.

The simulator offers rigorous thermodynamic models such as PC-SAFT EOS, GERG-2008 EOS, Peng-Robinson EOS, Soave-Redlich-Kwong EOS, and others. These models enhance the accuracy of simulations by enabling detailed calculations of thermodynamic properties. Additionally, DWSIM includes the IAPWS-IF97 Steam Tables for precise water property estimations, which are crucial in many chemical processes.

Users can benefit from DWSIM's parallel multicore CPU calculation engine, which optimizes the performance of the flowsheet solver. This feature leverages the processing power of modern mobile devices, allowing for faster simulations and improved efficiency in problem-solving. The ability to save and load XML simulation files directly on the device or in the cloud ensures that users can manage their projects effectively and access their work from multiple locations.

Exporting simulation results is made easy with DWSIM, as users can generate PDF and text documents from their simulations. This functionality allows for straightforward sharing and reporting of results, which can be useful in academic, professional, or industrial settings. The app also supports a comprehensive set of unit operation models, including mixers, splitters, separators, pumps, compressors, heaters, coolers, and various types of columns. These models are instrumental in accurately representing the different components of a chemical process.

In addition to unit operations, DWSIM incorporates support for chemical reactions and reactors, including conversion, equilibrium, and kinetic reactions. This enables users to simulate complex reaction networks and assess their performance under different conditions. The inclusion of reactor models allows for a more realistic representation of chemical processes, which is essential for accurate simulations.

DWSIM also features tools for conducting flowsheet parametric studies. The sensitivity analysis tool automates the process of running parametric studies on the user's process model, enabling them to evaluate how changes in variables affect outcomes. Furthermore, the flowsheet optimizer tool assists users in refining their simulation to achieve optimal conditions based on user-defined criteria. The calculator tool adds versatility by allowing users to perform mathematical operations on flowsheet variables and integrate the results back into the simulation.

For those involved in petroleum processing, DWSIM provides bulk C7+ and TBP distillation curve characterization tools. These tools facilitate the creation of pseudocompounds, which are essential for simulating operations in petroleum processing facilities. This feature enhances the app's applicability across various industries, making it a valuable resource for engineers working in chemical and petroleum sectors.

The user-friendly interface and detailed functionalities of DWSIM make it suitable for a wide range of applications in chemical engineering. By allowing users to conduct rigorous simulations and analyses, the app aids in the design and optimization of chemical processes.
