摘要：

In this paper various runaway criteria for batch reactors (BRs) and semi-batch reactors (SBRs) have been used and compared to study the boundaries of different thermal behaviors for the acetic anhydride hydrolysis reaction with the solvent of acetic acid carried out in BRs and SBRs. It is shown that the majority of criteria for BRs could give relatively precise results, but the remaining minority are less accurate due to they all have some specific assumptions. Besides, the simulated results indicated that all the criteria for SBRs could accurately identify the transition point from TR to QFS behaviors in spite of that they give slight different results of transition point corresponding to NI and TR behaviors. The results can give an effective instruction for selection and usage of runaway criteria, especially in terms of effectiveness and applicability, to easily identify thermal behaviors in chemical industry. © 2022 The Institution of Chemical Engineers
