I am so proud of our Mimic development team. When I think about our MYNAH Core Values of Innovation and Excellence, these guys always come to mind. On Friday, May 12th, they turned over to our customers the next release of Mimic v3.7.0, which includes the new Mimic Advanced Thermo Package. In building this new release, process plants no longer have to compromise in their use of high-fidelity dynamic simulations.
The promise of using advanced thermodynamics methods, like cubic Equations of State and activity models like NRTL, for dynamic simulation is the possibility of better model accuracy over a wider operating range. But the compromise that users have had to live with is settling for slower dynamic model response and less than real-time performance. Our team started by evaluating several of the more established and popular thermodynamics packages available. What we quickly found was a huge difference in dynamic performance from our Mimic Core Thermo and these packages. In most cases these thermo packages solved flash calculations at least 100x slower than in Mimic. When we also took into account that these package did not deploy a consistent multi-threaded, 64-bit software architecture, we became concerned about how using these packages would scale up to a large chemical or hydrocarbon unit. In order to deliver the value of advanced thermo without compromising dynamic simulator performance we had to take a different approach.
After trying out these other thermodynamics packages, we knew we had to take a different approach. We challenged the Mimic development team to look into building a native Advanced Thermo Package within Mimic that delivered greater model accuracy with the real-time, high-performance performance that our Mimic users have come to expect. These guys were ready for a challenge and they delivered all this in Mimic v3.7.0
The first goal of Mimic v3.7.0 was to deliver a set of advanced Thermodynamic methods and data to help users in the petrochemical, chemical, oil and gas, and refining industry develop accurate dynamic simulations of their plant for less time and money. The package is a full set of the most commonly used thermodynamics methods and data including:
Our second goal was also to reduce the time and effort required to build and maintain high-fidelity simulations using this package. Benchmark studies, by MYNAH's project engineering teams, show Mimic Advanced Thermo Package significantly decreases model tuning requirements. In addition, we made this new feature fit into Mimic's intuitive user interface by selecting Advanced Thermo in the Mimic Component Set configuration. This made configuration intuitive, flexible, and easy to change or maintain. To guide users through the selection of methods and data, our team made binary interaction parameters estimation wizards for the setup and tuning of component sets.
And the final goal was to avoid the big thermodynamics compromise. Unlike other dynamic simulation packages, Mimic runs flash and vapor liquid equilibrium at each model scan. This provides stable, smooth model performance. Some of our users have really fast processes. Even using the Advanced Thermo Package, models can run in 100 msec execution threads, performing with response and dynamics like the real process for these users.
Mimic v3.7.0 was released on May 16, 2017. Mimic users current on Mimic Software Support can upgrade to Mimic v3.7.0 at no additional charge. The Mimic Advanced Thermo Package can be added to any Mimic license that currently has Mimic Advanced Modeling Objects Core License and is current on Mimic Software Support. The release of Mimic v3.7.0 and the Advanced Thermo Package improves the performance and usability of dynamic simulation, providing greater life cycle benefits for process plants. The value of dynamic simulation is proven. Mimic v3.7.0 delivers greater business results for less time and money.
I look forward to your comments, questions, or suggestions.
Hope to hear from you soon.
