GCC (GENERALIZED CUTPOINT CONTROL)

crude switch

INFERENTIAL CONTROL OF FRACTIONATORS

Working over twenty years with crude units, Dr. Y. Zak Friedman of Petrocontrol, developed a form of inferential control that is totally based on process engineering procedures. These controls have been implemented on about forty crude units and other fractionators with a high degree of success. Several additional units are at various stages of implementation.

 

The crude unit control technology has proven to be:

Responsive to crude switches.

Simple to calibrate.

Self tuned.

Easily understood.

Reliable enough to replace distillation analyzers.

Can also work with analyzers.

Able to manipulate all column cooling circuits.

Multi variable dynamic capability.
