A singularly step-change technology to downstream as hydraulic fracking is to upstream 


Big Data Models

Penrose Technologies offers a next generation empirical & first-principles inferential control design that closes the gap between process identification and control design, a gap considered as the holy grail in application of predictive analytics and machine learning to the refinery and petrochemical industry.

Lower plant emissions

The distillation processes consume over 1/3rd of the US industrial energy demand. Distillation can consume up to 50% of a refinery’s operating cost due to energy intensive heating and cooling requirements. The next-generation Penrose Advanced Process Control technology targets reduction in heating and cooling requirements and consequently environmental emissions by 10 to 20%. The technology is more effective than state-of-the-art equivalents by an order of magnitude.

The equivalent annual CO2 emissions of 7.4 million cars are eliminated, if Penrose technology were to deployed at all U.S. refinery crude units.

A Step Change in Downstream

Penrose APC software technology has delivered moonshot results in driving significant improvements in productivity:

  • throughput capacity increase,

  • higher quality of products,

  • lower emissions and operating costs,

  • and higher stability of operations.



Penrose Technologies offers a next generation advanced process control technology for a true maximum hands-off control by plant operators and virtually zero maintenance and support by site engineering staff.




Self-Regulating vs Non-Self-Regulating Loops

For those APC Engineers who design, commission, and/or support APC Loops and Controls, a basic understanding of the two types/characteristics of Loops


Anti-Windup (ATW) and Anti-Reset Windup (ARW)

For those APC Engineers who design, commission, and/or support APC Loops and Controls, plus the Control System Engineers (CSE) who support the control systems


Defining Process Integrated APC (IAPC)

The APC foundation of "Complex Base Layer Controls" or "Complex Process Controls"  inside the DCS is a critical component of the overall APC strategy
