Checklist for Batch Reactor Temperature Control

Batch reactor temperature loops can use incredibly low lambda factors (e.g., 0.02). Lambda can approach a minimum that is the total loop deadtime. The tuning rules for an integrating process should be used to give a reset time that approaches three times the deadtime.

[PDF] High Purity Ethyl Acetate Production with a Batch .

Abstract—Ethyl acetate with the minimum purity of 85.0% by mole is inevitably needed as an active solvent used in a wide range of applications across many industries. It is normally produced by the esterification of ethanol and acetic acid. Due to the equilibrium limitation, it has been reported that the ethyl acetate with the maximum purity of 52.0% can be obtained in a batch reactor.

Batch Reactor - an overview | ScienceDirect Topics

Batch reactors are used to study the behavior of fluids with materials under various conditions of temperature and pressure. In a chemical process, horizontal or vertical vessels are also used to store fluids or to provide a volume so that a mixture of liquid and vapor can separate into two distinct phases.
