NewLand Control & Associates specialize in Advanced Process Control projects for continuous processes. Our experience and know-how help you select the most profitable cost effective combination of solutions, tailored to your process.
We provide turnkey solutions in an efficient implementation project, to provide you with benefits as early as possible.
Controller Health and Performance check: A quick scan of the entire control system’s performance and an assessment of the most beneficial loops and controllers to do maintenance on, together with an estimate of
the potential benefits.
Benefit Study: A thorough assessment of the most beneficial opportunities to improve your control system to capture more value from your process. Typically a study will take 2-4 weeks depending on the plant size.
The outcome will be recommendations with an estimate of the potential benefits.
Application revamp: Process re-designs often require re-thinking and revamping the control strategy. We can provide the know-how to help you optimizing your control system to maximize the benefits from your
Training: We offer several training courses to train your operators and engineers in the use and day to day maintenance of your applications.
Model Predictive Control: We are highly experienced in both Honeywell’s Profit Controller™ (RMPCT) and Profit Optimizer™ (DQP), as well as AspenTech’s DMCplus™.
Soft Sensor or Inferential: We offer you our own in house technology, but we can also use products from other vendors.
Turnkey Solutions: Together with our experienced partners we provide a complete team that covers all aspects of APC implementation.
Controllers lose part of their performance over time as the process they control changes, due to “wear and tear”, changed operating region or product and equipment replacement.
This applies equally for PID based controllers, as for model based Advanced Process Control (APC). The figure below gives a graphical representation of typical loss of performance in % of original, which directly translates in loss of
revenue. So, regular maintenance pays itself back very quickly.
Typical Controller performance degradation with and without annual maintenance
NewLand Control & Associates offer the following application maintenance services:
Controller Health and Performance check: A quick scan of the entire control system’s performance and an assessment of the most beneficial loops and controllers to do maintenance on, together with an estimate of the
PID loop tuning: Our experience and tuning tools allow you to efficiently tune multiple loops.
Soft Sensor inferential model tuning: Soft sensors are often a vital part of a control solution and need regular checking and tuning as well for best performance.
APC model update and tuning: Re-identifying the APC models. Including more variables in the application. Tuning of the application Adapting the built in optimizer to new strategies.
