Enhanced throughput capability

For many process units, increasing throughput brings substantive benefits. With APC you can push throughput to the maximum whilst monitoring all of the key constraints on the unit. At times when throughput does need to be reduced, due to constraints, it is reduced by the minimum amount using APC.

Increasing key product yield

Many processes produce more than one product where the key product is more valuable than the other product(s). Using APC the key product yield can be increased and the less valuable product yield will be reduced, maximizing the overall profit.

Reducing energy consumption

Minimising energy per unit feedrate is another key aim of APC and in today’s world, saving energy is increasingly important. The energy saving can include fuel and/or high pressure steam depending on the industry.

Better process stability

APC helps you to keep the process stable by monitoring all of the key constraints ina unit and taking into account upstream disturbances (feedforward variables).

Reduced material losses

When a process changes mode, many processes have losses due to the transition time and off-spec material produced during the transition. APC can manage transitional losses.


Crude oil distillation unit

Petrochemical industry

Advanced Process Control resulted in increased throughput and yield of the most valuable product streams, faster stable operation after a crude feed switch, more heat recovery and less furnace flue gas emissions.

Crude oil separation terminal

Oil and Gas industry

A combination of control techniques gave better control of the equipment load distribution and heat recovery, resulting in less compressor trips, significant energy savings and more stable product specification.

Milk Powder Drying

Food industry

Better simultaneous control of moisture content, maximum drying temperatures and intermediate storage residence times, resulted in reduced off-spec product, reduced moisture content give-away and significant energy savings. The benefits were obtained by redesigning the regulatory control system.

Ammonia Plant

Chemical industry

Advanced Process Control resulted in a 2.5% increased ammonia yield. The payback time of the project was less than 6 months.

NEWLAND CONTROL ARC-t

NewLand Control has developed ARC-t, Advanced Regulatory Control and PID tuning tool, for use in its projects and training courses. It is designed to support fast efficient tuning of various DCS and PLC based regulators.

  • Supported control structures
  • • Single variable PID loops
  • • Feed forward structures
  • • Dead time compensation algorithms (Smith Predictor, Predictive PI)
  • • Pairing for multi-variable PID or Dead Time Compensation loops
  • • Level PI tuning for vessels based on dimensions
  • Advantages
  • • Systematic approach for loops for which trial and error methods fail or are too time consuming
  • • Helps non-experts to get good tuning results
  • • User friendly with a well documented work flow
  • • Very cost effective

ARC-t licenses are sold combined with our Basic control and Advanced Regulatory Control training courses and our tuning services. Please contact us by email for the various licensing options. Method: Based on step test data, a dynamic model is identified. This model can have multiple inputs, so that models for feed forward signals can also be identified.

Alternatively for levels, integrating models can be calculated based on vessel dimensions. Based on these models, PI (D) or Dead Time Compensation algorithm parameters are automatically calculated for the feedback loop and optionally dynamic compensations for feed forward loops. Extensive simulation capabilities with nominal and perturbed models are used to access loop performance and robustness to model error and plant behavior changes and to compare different parameter set.

Controller maintenance

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.

Can I benefit from APC ?

If your process is strongly interacting and a few percent more plant throughput, higher yield of prime product, or energy reduction has a high value, then APC can generate an extremely good return on investment. APC usually requires an investment in interfacing a dedicated PC to your regulatory control hardware and requires training your staff in a new technology.
The benefits over simpler control improvements have to warrant these investments. NewLand Control & Associates, as technology independent consultants, can give you unbiased advice on what the most cost effective solution is for your particular situation.
