Abstract

Motivated by the need to reconstruct blends properties and their behavior in industrial distillation columns for control and monitoring purposes, the problem of the C7+ fractions modeling is addressed with substitute mixture of real components. The reliability of the proposed approach (comparable with the employment of hypothetical component as madein commercial simulators)is demonstrated in the context of the steady state simulation of an industrial debutanizer (located at SARLUX refinery, Italy).
