Description:

Severe loop interactions in multivariable control systems, such as distillation columns, often lead to frequent operator intervention forcing control loops to be operated on manual. Poor control causes loss of man-hours, product, and product quality. Where composition control is involved, this economic loss can be further compounded by the absence of frequent composition measurements. This paper discusses how rigorous steady state simulations were used to (1) reduce loop interactions in a naphtha splitter by employing RGA (Relative Gain Array) and SVD (Singular Value Decomposition) analysis and (2) achieve stable dual composition control based on an approximate linear model.
