Predict: Near Rigorous Model

Virtual sensor technology for distillation columns

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 with NRM:

NRM has the same accuracy of on-line analyzers but with no delay.

No need to wait hours for laboratory values.

No delay in getting results

Same accuracy of the on-line analyzer.

Online prediction of distillation properties of multistream columns.

Available for:

and other multistream distillation units

Calculate online also column parameters such as:

Kero 95 and Kero flash point NRM versus lab

Accurate dynamic prediction of internal flows

Accurate prediction of feed type

Characterize the feed quality with the same accuracy of an on-line density meter.

Use this information to improve feed switching performances.

Accurately predict product composition, even at high purity for two-products distillation columns.

Predict product composition for two-products columns, such as:

and many others.
