A model for the dynamic simulation of multistage flash desalination units has been developed, based on a detailed description of the fundamental elementary phenomena involved in the process. It takes into account stage geometry, physico-chemical and transport properties of water, vapor and brine and the different non-idealities of the process. In this work the model is used to describe the behavior of the MSF plant under different kinds of process disturbances, thus showing some of its nonlinear dynamic features. Further applications of the model may deal with the analysis of steady-state stability and the development of optimal control strategies and start-up/shut-down procedures.

Abstract

In this work the model is used to describe the behavior of the MSF plant under different kinds of process disturbances, thus showing some of its nonlinear dynamic features. Further applications of the model may deal with the analysis of steady-state stability and the development of optimal control strategies and start-up/shut-down procedures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
