VPI Soft Sensors
Design, calibrate and integrate real-time property predictors on any APC software platform.
Explore the powerful NRM technology for distillation columns.
A digital twin for on-line property prediction
Build a high-fidelity simulation of your distillation column and run it on-line. Predict critical properties in realtime. Save on the cost of an expensive on-line analyzer and stop waiting for lab results. Use a state-of-the-art browser-based application interface to build and maintain the virtual sensors. Embed NRM in any existing APC application, from Honeywell Profit Sensor Pro, AspenTech AspenIQ, and Shell PACE. No additional software or hardware is required.
Replace online analyzers
Replace online analyzers with NRM:
No maintenance cost
Easy to implement
Better dynamic performances
NRM has the same accuracy of on-line analyzers but with no delay.
No need to wait hours for laboratory values.
Real Time results
No delay in getting results. Same accuracy of the on-line analyzer.
NRM for Main Fractionator
Online prediction of distillation properties of multi-stream columns.
Distillation curve and cold properties
Predict the most common qualities:
ASTM distillation points
Flashpoint
Freezing Point
Cloud Point
Available for:
Crude distillation units
FCC main fractionator
Vacuum units
Hydrocracking fractionators
and other multi-stream distillation units.
Accurate in a wide operating range
Kero 95 and Kero flash point NRM versus lab. Predict column parameters
Accurate dynamic prediction of internal flows. Not only product qualities
Calculate column parameters such as:
Liquid and vapour flow
Flooding percentage
Dew point
Predict column parameters
Accurate dynamic prediction of internal flows. Characterize feed quality
Characterize the feed quality with the same accuracy of an on-line density meter. Use this information to improve feed switching performances.
Online feed quality detection
Accurate prediction of feed type. NRM for Light Ends
Accurately predict product composition, even at high purity for two-products distillation columns.
Accurate at high purities
