Inferentials are real-time signals typically implemented in the process control network (PCN) and used to monitor, control and optimize product qualities for multi-draw fractionators and two-product towers in refineries and petrochemical plants.
Soft Sensor Benefits
Our real-time soft sensor data streams support measurement, monitoring, control, optimization and planning functions for your critical product qualities.
The Petrocontrol multi-draw fractionator solution is implemented in oil refineries and petrochemical plants world-wide.
Our philosophy is to serve as a partner every step of the way from design through ongoing support and maintenance of your soft sensors.
Petrocontrol's inferential technology is field-proven in over 1500 applications installed on over 100 process units in oil refineries and petrochemical complexes world-wide.

Crude switches are automatically detected and factored into the inferential product property calculations that form the soft sensor signals.
Generalized Cutpoint Control (GCC)
GCC is a compact, integrated package of constraints, dynamics, manipulated variables, and inferential models. To increase its speed and simplicity, GCC takes into account a finite set of instrument measurements with no redundancy.
Generalized Distillation Short-Cut (GDS)
GDS is an inference model for predicting distillation top and bottom product purities. It has been implemented on a wide variety of distillation equipment, from simple light-ends columns to superfractionators.
