Modern technology offers the most effective solutions to any technological problem or problems. As the complexity of the structure of modern refinery, advanced process control (PMTK) becomes necessary complement to the standard methods of process control and allows to achieve the planned performance and to achieve compliance with the requirements of the customer. For refineries and chemical companies often need to increase productivity, energy efficiency, overcome production constraints and optimization of working time, as well as many other tasks.
By optimizing the performance of their production units, industry leaders will be able to achieve a higher level of return on investment, and in fact provide the highest possible profitability. What tools can help process engineers to improve the economic efficiency of the use of advanced methods of process control and to ensure the achievement of the business objectives?
Today, process engineers need to exercise tighter control of manufacturing operations to achieve better performance of the enterprise with a complex process, while reducing costs. Typical applications for process control are usually created with the fundamental assumption that the developed industrial engineer model will always be accurate and properly structured. However, changing the technological performance of refineries and targeted economic parameters, this assumption has to be wrong, because the process characteristics change over time. Although the controller can work quite accurately immediately after the start, at some point in the future it may cease to do so, so the goal is to automatically determine when this occurs and make the necessary adjustments in the continuous mode.
If there are problems with the reliability of the model, setting the controller must also change to prevent potential negative impacts. Therefore, it is important that the process engineer had the opportunity to monitor change in the parameters of the process and correctly interpret its current characteristics.
Most importantly, it allows you to configure the controller to the stage of the test, operation, maintenance and upgrading, providing benefits such as reduced operational costs and risks associated with the insufficient accuracy of the constructed model.
Intelligent Software
For more than 20 years AspenTech Aspen DMCplus® company is the industry standard software for modern methods of process control. Thanks to a completely reworked simulation environment and the emergence of adaptive software solutions for process control (AUCC) processing industry received a powerful new tool – the app Aspen DMC3, enabling more effective management of technological operations and improve profitability. This technology offers a wide range of economic compromise solutions for managing tests a step change parameters and model building. In fact, it eliminates the need for an approach to the AUCC as a project, and forms a continuous process of assessing the quality of the background model, intelligence gathering and creating new models that reflect the changing conditions of the plant. The project to create AUCC has arisen in connection with the need to solve the existing problems related to the development and support of management applications. This intelligent software can detect, isolate and correct problems, removing this burden from the engineering professionals. Key benefits of AUCC, compared to traditional approaches based on sustainable values, include features to ensure a constant analysis of the model management process for accuracy, low efficiency of the allocation of areas of the model, new data collection with the characteristics of the process in the background without interrupting the production process, optimizing the operation of the plant, and monitoring the new real-time data and incorrect selection of data and their subsequent removal. Facilitate the establishment of data management processes step by step working out and getting results, AUCC expands the capacity and efficiency of its use.
There is a significant difference between the traditional approach to the operation of the controller (use of sustainable values) and Adaptive process control. When a stable value, the modernization of the controller is usually part of a long and expensive process. Whereas AUCC work intelligent processor automatically corrected in the background, without interrupting the factory processes. Adaptive management process can improve long-term profitability by eliminating the need to quickly change the process and ensure optimal management of the factory production. Refineries and petrochemical plants there is a significant benefits in improving product quality, increasing its volume, and lower energy costs, and, ultimately, a quick payback. Maintenance of the application at peak performance is a challenging task for existing controllers. As we all know, the use of more rapid and effective management can improve the level of return on investment, and that is why AUCC opens up new possibilities for the use of this technology as part of the intellectual approach.
Management technology, established by AspenTech, is independent of the use of distributed control system (DCS), which is important in terms of mixed systems in use today DCS. The functionality of adaptive management process allows you to create high-end models without the need to turn off the controller, providing a significant reduction in time-consuming operations.
New era
What is new here? Today, technological project has been raised to a new level. IN DMC3 from AspenTech combines leading industry technology DMCplus with the most innovative tools for creating and maintaining control programs, providing a complete set of the required functions. IN Aspen DMC3 provides a process engineer key features, allows you to adjust the behavior of the controller, depending on the needs of the current mode of operation (for example, when you change the performance of scheduled refinery or economic parameters of his work). A new feature of successful identification of the model with restrictions in Aspen DMC3 allows the use of existing data on the process for the formation of more effective predictive models in management applications.
Innovation and economic performance are closely linked. On the one hand, the AUCC in Aspen DMC3 allows you to select the optimum ratio of the economic parameters to speed processing and the formation of the model. On the other hand, the function of sustainability in Aspen DMC3 allows you to customize operation of the controller in a mode to optimize the management. Set the level of sustainability, the process engineer can determine the degree of activity of the controller to reduce the risk of insufficient to bring the model to the specified conditions. Binary selection is replaced continuously-variable scale, providing a thorough regulation of the relationship between the technological and economic factors involved in the AUCC. Enterprises get significant advantages, including a more effective setting economic parameters in AUCC to meet ever-changing business goals. In addition, users can now customize the behavior of the controller when working out the trial, as well as in the stages of creating a model and prepare for the operation.
More opportunities to increase profits
A more reliable control of the process increases its effectiveness and safety, as well as the quality of the final product. Sustainable management reduces the risks associated with poor tuning and debugging the model. Innovative software for AUCC allows you to achieve the maximum performance possible refinery to maximize the production volumes of the highest quality products with the highest price, and to ensure the optimal level of power consumption.
IN Aspen DMC3 marks a new era in the development of technologies AUCC. By eliminating the risk of any errors in the model and improving the efficiency of the process control in the dynamics of this revolutionary innovative software tool allows you to optimize the production process, reduce waste, and reduce overall costs.
In conclusion, it should be said that with the new technology AUCC implementation and practical application of advanced methods of process control is no longer a project could be hard and in fact is a program of continuous improvement. Now companies are able to provide a reliable process control and a significant increase in ROI.
