Section 7 - Measured Conversion (Measured_Conv)
7.1 Overview
In This Section
This function calculates the measured conversion and measured severity based on
the process measurements. Prior to outputting the conversion and severity the
values are filtered. Last good value holding is also available.
Usage of
Measured_Conv
The Measured_Conv outputs both measured conversion and measured severity.
The measured severity is input to Calculation_Comp, which uses the measured
severity to bias, and corrects the predicted severity based on differences with the
measured severity.
Since measured conversion is defined as the percent of feed converted to product
excluding the Cycle Oil product, the user must input the total feed flow rate and
the total cycle oil product into Measured_Conv.
Measured_Conv also takes inputs from the Gasoline_Prop and CycleOil_Prop
functions. These functions provide corrections for cycle oil lost to or gained from
adjacent products due to deviations from design conditions.
