Input-output information for the behavior analysis space

Design specifications Design/operational variables Domain knowledge 

The analysis of steady-state behavior allows the designer to explore the effect of kinetics, gas/liquid mass transfer and hydrodynamics and the steady-states of the unit. On the other hand, dynamic simulations are carried out to check the robustness of the design, in terms of the ability of maintain product purities and conversion in desired range 

This chapter addresses those two aspects of process behavior steady-state and dynamic operation. In the first case, a reactive flash with a rather ideal exothermic isomerization reaction is considered. This simplified system is selected to accoimt exclusively on the effect of phenomena interaction on the occurrence of input and output multiphcity. Therefore, any effect related to unit configuration is considered outside the scope of the analysis. 

The second part of this chapter deals with the dynamic behavior of a full RD column, with special focus on the synthesis of MTBE. Although the design of the control structure is rather conventional (SISO and PI controllers), it is regarded as reference case for the new developments to be introduced in chapter 8. 

Recalling the engineering and scientific design questions given in chapter 1, in this chapter we address question 6, namely,
