Process Control
Agile supply chain planning
Providing a common workspace improves data integration
Service-oriented architecture simplifies data source integration
Here's how the approach helps refinery scheduling and also contributes to business-wide SOA adoption
Predicting octane numbers for gasoline blends using artificial neural networks
The ANN models were more accurate than regression models
Implementing and maintaining advanced process control on continuous catalytic reforming
The primary benefit was an increase in reformate octane barrel yield from operating the plant at its economic constraints
Fine tune accuracy in analytic measurement-Part 1
Understanding the root causes of time delay
HP Control: APC for min maintenance or max profit? - Part 1
First, thanks to Dr. Y. Zak Friedman1 for referencing my July 1997 HP editorial.2 I commend him for using HP publications from more than a decade ago in his editorial. While I appreciate Dr. Friedman'..
HP Control: Temperature points on main fractionators
Main fractionators are distillation columns that handle wide boiling curve feeds, cutting it into several products. Almost every major refinery unit has such a column, all with similar design features..
HP Control: APC designs for minimum maintenance—Part 3
This is the third in a series of three editorials about designing advanced process control (APC) applications for an environment of little to no maintenance. Having lamented for years about APC applic..
HP Control: APC designs for minimum maintenance—Part 2
My last month's editorial proposed that since our advanced process control (APC) applications are by and large under-maintained, these applications should be designed in the simplest possible way. The..
