シミュレーション・テクノロジー List of Products and Services

ProSim Plus HNO3 is a product of the French company Fives ProSim, designed based on over 30 years of experience in modeling and simulating nitric acid plants and nitrous acid vapor absorption systems (mainly referencing Professor Xavier Joulia's 1981 paper "Contribution au développement d’un programme général de simulation – Application à l’analyse du fonctionnement d’un atelier de production d’acide nitrique"). In addition to the standard features of ProSim Plus as a process simulator, it incorporates rigorous models for chemical reactions and mass transfer rates in gas-liquid phases in absorption towers and condensers, as well as oxidation reactions in the gas phase within heat exchangers and piping. Notably, the oxidation reaction from NO to NO2 in the gas phase applies a rate model rather than an equilibrium model.

• simulator

Batch Column is a product of the French company Fives ProSim and is a non-stationary simulator for batch distillation processes. It is utilized in manufacturing processes for pharmaceuticals, specialty chemicals, essential oils, and alcohols, where a single distillation unit separates numerous complex mixtures, to achieve optimal production processes by reducing operation time, meeting product separation specifications, and minimizing energy consumption. BatchReactor offers a wide range of features that enable the simulation of most batch distillation processes.

• simulator

Batch Reactor is a product of the French company Fives ProSim and is a non-steady-state simulator for batch reaction processes. Chemists and process engineers can utilize the tools of Batch Reactor for simulation studies to reduce production costs, comply with environmental and safety regulations, and save time in scale-up phases and new product development. Batch Reactor offers a wide range of features that enable the simulation of most batch reaction processes.

• simulator

ProSim Plus is a product of the French company Fives ProSim and is a general-purpose steady-state process simulator that includes optimization features. In addition to a rigorous thermodynamic model (also sold as a separate product called Simulis Thermodynamics), it is equipped with precise models of chemical engineering unit operations such as heat exchangers, reactors, distillation columns, absorption columns, and extraction columns, allowing for the modeling and simulation of large manufacturing processes, including complex recycling. Designed with the concept of Open Software, it enables users to add custom unit models and modify or extend standard models using Visual Basic. It complies with Cape-Open standards and allows for the integration of models from compatible external software for simulation.

• simulator

SIMULIS THERMODYNAMICS is a product of the French company Fives ProSim. It allows for the precise estimation of thermodynamic properties and phase equilibrium states for plant engineering, and can be used as a Thermodynamic Calculation Server accessible from Excel add-ins and MATLAB toolboxes. There are over 30 model equations available for both equation of state models and liquid phase activity coefficient models, along with a standard database of pure substance data (DIPPR) and a Binary Interaction Parameter database. It is also capable of estimating pure substance properties and mixture phase equilibrium properties using the group contribution method. It complies with the Cape-Open standard, allowing integration with other general-purpose simulators and the incorporation of other property estimation software.

• simulator

Digital twin construction environment for water treatment plants based on Dynamita's process simulator Sumo • Monitoring DT (MDT): Runs in real-time and displays data and model results for comparison. • Optimization DT (ODT): Finds the optimal DO set points for the next 2-4 hours to achieve target ammonia levels in the effluent. • Automatic Calibration DT (ADT): Adjusts selected model parameters to match model output with sensor data. • Forecasting DT (FDT): After training on historical data, it can predict expected peak inflow to the plant based on weather forecasts (for a few days or a week ahead).

• Production Management System

The SUMO water treatment process simulator developed by the French company Dynamita can rigorously model a variety of water treatment processes, including biological treatment such as activated sludge and anaerobic digestion, chemical phosphorus removal, and coagulation and sedimentation processes, both in steady-state and unsteady-state conditions. Thanks to its open architecture, it is easy to customize models and add user-defined models, and it also allows for bidirectional linking with other programs. It is widely used for municipal wastewater and drinking water treatment as well as for wastewater treatment in chemical plants. *For more details, please refer to the PDF materials or feel free to contact us.*
