Composition estimation method and control for distillation columns

摘要

Estimation method and composition control for distillation columns. # Estimation method and composition control for distillation columns comprising a head tank, a tank of glue, at least one plate between the tank head is described and the tail tank. The present invention provides a system for estimating composition and level for a distillation column by using control techniques based on neural networks and genetic algorithms, the estimate is made on the composition of head and tail of the column-based networks secondary variables using neural easily measured.
