Yokogawa has announced that together with Shell, it has developed Platform for Advanced Control and Estimation R5.02. This software suite brings together advanced plant process control technology developed by Shell with the real-time control technology that Yokogawa has developed in its role as a control system supplier.
The upgrade from version R5.01 provides enhanced functionality that will help customers optimise the control of operations throughout their plants, maintain high system availability, reduce operator workload, and improve productivity. The Platform for Advanced Control and Estimation suite is positioned as a solution in Yokogawa’s OpreX Asset Operations and Optimisation family.
Advanced process control systems improve product yield and reduce energy consumption by maintaining temperature, flow rate, pressure, and other process values within a set range, keeping them as close as possible to their optimal set points. Such systems are increasingly used in facilities such as oil refineries, petrochemical plants and natural gas liquefaction trains. Advanced control solutions are attracting considerable interest due to their ability to improve productivity.
Yokogawa’s Platform for Advanced Control and Estimation suite delivers the following functionality:
• Multivariable model predictive control (the control of multiple variables based on predictions made using models of the dynamic characteristics of plant responses).
• Soft sensing for estimating quality in real time based on temperature, flow rate, pressure, and other process values.
• Customisation of calculations.
The suite is continuously enhanced in response to changing customer requirements. The release of version R5.02 meets the need for solutions that can optimise the control of operations throughout a plant, ensure high availability, and alleviate problems of high workload caused by reductions in the number of plant operators and expansion in the range of items that must be monitored and controlled.
Enhancements
1. Plant-wide optimisation of control with large-scale applications
With large-scale applications, advanced control systems need to be able to process huge amounts of data. Version 5.01 of this software is suitable for small to medium-size applications and can optimise the control of individual processes. With the enhancements made to R5.02, this software now offers significantly greater processing speed. As a result, it can now handle large-scale applications involving multiple processes and is thus capable of optimising the control of operations throughout a plant.
2. Maintaining high system availability regardless of changes in operational conditions or ageing of facilities
With this software, a trend line showing the predicted values when advanced control is active (closed loop prediction trend) can be superimposed over a trend line that is based on the actual measured values. By comparing them, it is possible to identify errors in a dynamic response model. Such errors are the result of deterioration in advanced control performance caused by changes in operational conditions or the ageing of facilities. System availability can be maintained by rebuilding the dynamic response model whenever these errors become significant.
R5.02 has been enhanced to enable the display of a trend line that predicts plant behaviour when advanced control is inactive (open loop trend). This enables operators to know in advance what impact this will have on a process.
3. Improved operability for efficient operation and monitoring
With a single press of a key, operators can call up items from a list of recently displayed screens. Frequently used screens can also be accessed quickly by registering them as favourites.
