On-line Observation for the Unmeasurable Inputs in FCCU Riser

摘要

This article makes the FCCU as the research target, basing on the simplified FCCU reaction-regeneration mathematic model which developed by the author's lab. The simulation system of FCCU reactor-regenerator is developed on the XD-APC software. Use this system to get the simulation data of the FCC unmeasured inputs through some typical arithmetic, then use the BP neural network to observe the unmeasured inputs on line.
