Designing and analysing parallel control for multifeed ternary systems

This paper explores a parallel control structure for improving the behaviour of a chemical plant having recycling and multi- ple feed streams; a ternary system is taken as an example,having an A + B → C second-order irreversible reaction. Material recycling dynamics can induce the so-called snowball...

La dinámica inducida por el material reciclado puede provocar el llamado efecto bola de nieve ante la presencia de perturbaciones en la corriente de alimentación. Con el esquema de control paralelo el efecto bola de nieve se puede prevenir mediante la distribución de carga a través del proceso. Con este fin, se propone una estructura de control donde la composición del producto está regulada por medio de la manipulación simultánea de la relación de vapor de la columna final y la temperatura del reactor. Se realiza una extensión a proceso de un reactor, una columna de destilación y un flujo reciclado. Simulaciones no lineales muestran la efectividad del control de composición con esfuerzos de control de vapor moderados.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/15727Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 30, núm. 2 (2010); 25-34 Ingeniería e Investigación; Vol. 30, núm. 2 (2010); 25-34 2248-8723 0120-5609Solar-González, Rocío (2010) Designing and analysing parallel control for multifeed ternary systems.

description This paper explores a parallel control structure for improving the behaviour of a chemical plant having recycling and multi- ple feed streams; a ternary system is taken as an example,having an A + B → C second-order irreversible reaction. Material recycling dynamics can induce the so-called snowball effect in the presence of disturbance in the feed stream. The snowball effect can be prevented by distributing load through the parallel control scheme. A control structure was thus pro- posed where product composition was regulated by means of simultaneous feedback manipulation of final column vapour boilup rate and reactor temperature. An extension was made for one reactor, one distillation column and recycle stream configuration. Nonlinear simulations showed that effective composition control could be obtained with moderate vapour boilup control efforts.
