HP Control: Temperature points on main fractionators

Hydrocarbon Processing / September 2009
Petrocontrol: Friedman, Y. Z.
Process Control

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

Hydrocarbon Processing / August 2009
Petrocontrol: Friedman, Y. Z.
Process Control

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

Hydrocarbon Processing / July 2009
Petrocontrol: Friedman, Y. Z.
Process Control

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..
