It was developed by drawing on some advanced concepts from foreign dynamic simulation software, as well as the advantages of domestic software resulting from practical experience in domestic chemical engineering projects. 2. Software functions: Utilize mechanism modeling to create accurate process models that simulate the process flow and operational procedures in actual production processes. Process model design software should possess, but is not limited to, the following functions: ① Graphic modeling – Process model design software should use a graphical user interface, and such an interface needs to be user-friendly. ② Software that is easy to understand and maintain should include basic unit operation modules (such as pumps, valves, distillation columns, heat exchangers, reactors, etc.). By configuring the parameters of individual modules and connecting them together, it is possible to create a model of the entire plant facility. The purchaser can adapt to changes in the actual devices by modifying the module configurations and connections, without the need for any programming of the source code. ③ The software must support real-time online modifications; the purchaser can change the device parameters and process flows online in order to observe and study how the parameters of the device change over time. ④ It supports paging-based modeling as well as import and export functions. To meet the requirements of segmented operations on devices, it allows for paging-based modeling with overlaps; the resulting models can be exported directly, facilitating the division and combination of devices into different sections. ⑤ To be compatible with multiple operating systems, it should support at least Windows and Linux. ⑥ The mechanism modeling model is the core of a dynamic simulation system, as it directly affects the accuracy and quality of the simulation carried out by that system. All models must be based on rigorous thermodynamic and kinetic mechanism models, that is, using equation of state to determine chemical and phase equilibria, and establishing chemical reaction kinetics models to calculate reaction rates. Such rigorous models are suitable for complex systems with multiple components, multiple phase transitions, and chemical reactions; they can accurately describe the dynamic characteristics such as pressure, flow rate, temperature, composition, and energy of various equipment combinations in industrial plants, and possess good extensibility. The final process model should exactly match the steady-state condition of the simulated plant facility, and accurately reproduce various dynamic characteristics of the simulated plant facility. Model algorithms need to be developed and tuned based on fundamental principles such as heat transfer, mass transfer, momentum transfer, chemical reaction kinetics, chemical engineering thermodynamics, and automatic control. 3. Scope of application: ① Chemical manufacturing enterprises, as well as universities and vocational colleges that need customized industrial-grade OTS systems for training purposes; ② Teaching tools required for providing comprehensive learning experiences to students.

Advantages: The entire simulation training system should have good adaptability, being able to fully accommodate various operations within the limits permitted by the process, including startup, shutdown, and fault handling; its simulation results should reflect patterns that are consistent with those in actual production facilities. The simulation operation training system can be used not only for operator training, but also to assist customer companies with process design, control system testing, start-up and shutdown tests, as well as operation optimization. Furthermore, thanks to the integrated \"Operation Guidance Scoring System\", it is also possible to check and evaluate the performance of trainees. Its main functions can be reflected as follows: 1) It simulates in a realistic manner the startup, shutdown, and normal operation adjustments of various devices, thereby meeting the training needs of operators in terms of skills related to the startup and shutdown of process equipment, helping to develop reasonable startup and shutdown plans, and enabling them to become familiar with the steps and processes involved. 2) Simulate abnormal production conditions in various units, such as emergency shutdowns and equipment failures, to train operators in the ability to handle and diagnose faults on-site, thereby improving the safety of production in these units and reducing the generation of defective products. 3) By mimicking the DCS operation format, operators can become familiar with and proficient in DCS operation methods in advance before entering the actual production facility, thereby reducing the adaptation period. 4) It can serve as an important means for assessing the skills of operators of various devices, enabling the evaluation of their operational skills and facilitating a quantitative assessment of their technical capabilities, thereby helping to improve the level of their operational skills. 5) It can meet the needs of engineering and technical personnel and experts for process optimization, parameter adjustment, and scenario forecasting. It enables research and testing of process solutions, allows for comparison of different operation scenarios, facilitates dynamic technical research on the process, optimizes production plans, and guides production operations. 6) Verify and inspect the control systems and interlock logic systems in each device that have not been tested in practice, to confirm the correctness and rationality of the control logic. 6. Achieved results: For continuous production systems with detailed data, an error of within 2% can be achieved for key parameters, and within 4% for secondary key parameters.
Chemical enterprises can all serve as users; as for the application needs in other industries, it may be necessary to establish connections in order to understand them. Another category includes universities

If used in universities as a teaching tool, similar to tools such as Aspen and HYSYS, is it not feasible to employ this platform? After all, when used for teaching purposes, students need to learn how to use this platform to work on practical project cases; they require comprehensive knowledge of processes, instruments, equipment, etc., as well as an understanding of how to carry out dynamic debugging. This is very helpful for improving the skills and capabilities of university students. Moreover, if universities establish partnerships with companies and have actual projects to work on, this platform can meet the requirements for implementing those projects, enabling a seamless transition from teaching to project execution.
Push it once a day to ensure it doesn’t sink; no one uses the free trial either?

Quite a few people have downloaded it; I haven’t seen anyone asking for an authorization code, and it can’t be started without one
