AlphaNRM — Near Rigorous Model
A virtual sensor for distillation columns — predicts critical properties in real time, with the accuracy of a lab result and none of the delay.
AlphaNRM is a standalone digital-twin product — a virtual sensor for distillation columns, embeddable in whatever APC you already run. Deploy it alongside ChatAPC and its real-time predictions also feed straight into the same plant graph, so every answer accounts for what AlphaNRM already knows.
A digital twin, running online
A high-fidelity simulation of your distillation column runs in real time, built and maintained through a browser-based interface — no new hardware.
Replaces the delay of an online analyzer
Same accuracy as an on-line analyzer, with no maintenance cost and no waiting hours for a lab result.
Main fractionators
Predicts ASTM distillation points, flashpoint, freezing point, and cloud point for crude units, FCC fractionators, vacuum units, and hydrocracking columns — plus internal flows, flooding, and feed quality.
Light-end columns
Accurate even at high purity, for two-product columns like naphtha splitters, LPG splitters, debutanizers, and benzene/toluene splitters.
