The dynamic mathematical model of the technological process
The most important component of the simulator complex is a mathematical model of the technological process, which allows to accurately simulate the technological process in regular, off-nominal and emergency situations.
T-Soft has accumulated considerable experience in the development of mathematical models. This makes it possible to reproduce the dynamics of the technological process as accurately as possible, which ensures that the personnel have the right skills to manage the facility (either unit or shop) in various situations.
The extensive bank of high-precision models approved by T-Soft allows to simulate any technological process of the oil refining and chemical industry.
The use of exclusively developed models allows to adapt their parameters to the specifics of each particular production as much as possible, as well as to unlimitedly expand didactic properties, lists of failures and emergency situations.
Classification of technological process models
| Description | Sustainability of work | Application | |
Basic |
The laws of conservation of mass and energy are exactly fulfilled in the models. Reactors, absorbers and extractors are calculated in the one-dimensional approximation for thermodynamic equilibrium states. When modeling columns, the nonideality of the heat and mass transfer processes is taken into account through the efficiency of the plates. | throughout the range of the facility’s operational modes | Training, testing of control algorithms, solving certain technological problems |
Improved |
The geometry of the machinery is specified in the models, as well as the effects of two-dimensionality and inhomogeneity are taken into account, stationary and equilibrium calculation schemes are replaced with kinetic equations, the diffusion and heat transfer processes are described in the boundary-layer approximation. | within the range of normal mode fluctuations | advanced process control testing, solution of technological problems, technology analysis, debottlenecking |
Research |
That is the most detailed model, based on the latest achievements in calculating the simulation of specific processes and devices. It is designed individually on the basis of the customer’s emerging needs in the research process. | within the range of the research area | advanced process control testing, solution of technological problems, technology analysis, debottlenecking |
Custom-tailored approach to the selection of the technological process model
When developing the simulator, it is the mathematical model of the process optimal for the balance of accuracy and speed that is formed. In this case, each type of apparatus (column, heat transfer unit, recipient, etc.) can be described in general by several models or several modifications of one model with different ratios of accuracy / speed indicators.
The T-Soft model bank allows selecting the optimal modification of the mathematical model of each apparatus for a specific task.
When choosing a particular model, the following factors are taken into account:
- the intended use of the CPC;
- function of the apparatus in the production line (main or supplemental);
- list of process parameters controlled by the operator;
- the need to monitor the internal parameters in the apparatus, characterizing the safety of its operation;
- the need to control the order of work on the device (for example, the order of starting the pump, the schedule of starting the compressor, etc.).
