Benchmarking changes in the process operating state

The aim of the CHEM project was to develop and implement advanced Decision Support Systems (DSS) for process monitoring, data and event analysis, and operation support in industrial processes. The systems are synergistic integration of innovative software tools, which improve the safety, product quality and operation reliability as well as reduce the economic losses due to faulty states, mainly in refining, chemical and petrochemical processes.

The CHEM applications consist of integrated sets of software toolboxes that provide robust detection and diagnosis of process problems in real-time. The systems assist operators in assessing process status and responding to abnormal events. The project provides a flexible architecture and a methodology in order to facilitate the development of such applications on many processes.

Typical industrial processes have several discrete operating states. These states can be defined by, e.g. the raw material used or the end product produced. In a paper machine, the most important discrete operating states are the paper grades produced. Speeding up the grade changes can significantly increase the production efficiency of a paper machine.

This toolbox ('Benchmarking changes in the process operating state') provides functionality for analysing and benchmarking changes in the operating state of a process. Benchmarking is based on keeping a record of state changes. Values of various performance indices from each state change are stored in a database. When analysing a new state change, the corresponding changes (i.e., all changes from state A to state B) are searched for, and used as reference material in the analysis.

The changes are analysed to determine how the multiple goals, such as speed and safety, have been reached in a particular state change. Multiple corresponding changes are analysed to determine the bottlenecks, which should be addressed when speeding up the changes.

The toolbox is being marketed under the name KCL-GraPPa (the Grade Change Performance Package by KCL).
