Selection of Temperature Control Trays

Sensitivity analyses were performed on these five esterification reactive distillation systems. In order to find the steady-state gains of the tray temperature in the linear region, extremely small step changes (+ 0.1%) are made in the manipulated variables. 

CONTROL OF REACTIVE DISTILLATIONS EOR ACETIC ACID ESTERIFICATION 

The type III flowsheet is quite similar to the type I flowsheet topographically except that a decanter is used to replace the reflux drum and the organic phase is under total reflux (Fig. 13.1). For the BuAc system, an increase in the heat input leads to temperature rises throughout the column except for the upper section of the column. This behavior is quite similar to that of the MeAc system. In the column design, the HAc concentration is kept low toward the lower section of the column (Chap. 7) to meet
