The smart technology differentiator APC applications deliver large operational benefits immediately after commissioning, but plant performance degradation will occur over time. This is mainly due to the constant changing conditions within the plant itself as opposed to problems with the technology.

Recent innovations in APC deliver significant improvements to both controller sustainability and initial application development. Hence, today there is an intelligent technology differentiator that delivers continuous APC sustainability. Adaptive Process Control developed by AspenTech is a revolutionary breakthrough technology that eliminates the need to approach APC maintenance as a project and creates a continuous process of assessing model quality, collects current data and generates new models as the behavior of the plant changes over time. This smart software can detect, isolate and correct problems without increasing the burden on engineering staff.


A Crucial Difference to Traditional Process Control Standards

There is a crucial difference between the traditional approach to controller maintenance (sustained value) and Adaptive Process Control. With sustained value, revamping the controller is typically carried out as part of a lengthy and costly project.

Under Adaptive Process Control, however, the clever controller is modified over time in more of a continuous process. The update of the model occurs without the need to take the controller off-line and enables a company to reap the benefits of control and optimization while the model is under maintenance. Model quality analysis, which continually runs and assesses the accuracy of the model, can detect when performance degradation occurs. It can pinpoint a specific part of a controller, thereby helping engineers to determine the underlying cause of the degradation.

The Long Time Benefit of Control Technology

Over a long period, companies lose substantial profits because the plant conditions change. The additional benefit of Adaptive Process Control is the ability to squeeze every possible gain in monetary terms from the asset on a continuous basis. Crucially, the software permits engineers to take decisions when new models replace existing ones in on-line applications.
