Process Control
HP Control: What constitutes a real-time application?
I recently heard computer programs, mainly of the simulation variety, described as working in real time in service of the unit operators, inferring product properties and other unmeasured constraints ..
HP Control: Are there any good APC training programs out there?
I have written several articles and editorials warning about the failure rate of advanced process control (APC) applications. See for example my January 2006 editorial,1 which also references related ..
Increase product value through process modeling
Using a rigorous refinery-wide simulation, a refiner moved more low-value products into value-added end products
Accurately predict radiation from flare stacks
Using this technique can take the guess work out of design calculations and improve costs
Logistics: the missing link in blend scheduling optimization
Incorporating them can yield significant improvements in efficiency and productivity

Understanding the stages and having a strong vision of where you need to go are essential first steps
HP Control: Solomon Associates' advanced process control survey
Measuring advanced process control (APC) benefits is as important as it is difficult. We justify APC projects on estimations that the unit operation would improve. To the extent that these preproject ..
