Classification and optimization of homogeneous reactions with arbitrary reaction orders performed in isoperibolic semi-batch reactors using θMTSR criterion

Abstract

Runaway reactions are very dangerous, and studies on them are indispensable. A lot of criteria have been developed to classify different thermal behaviors. A fine criterion (named as MTSRC) for 2-order homogenous reactions performed in isoperibolic SBRs has also been developed in our previous work. In this paper, firstly MTSRC is amended and renamed as θMTSR criterion. Then θMTSR criterion is further extended to reactions with arbitrary reaction orders. Based on θMTSR criterion, the boundary diagrams (BDs) are reconstructed with a wider scope of model parameters and more data points compared to BDs in previous work, and particularly the influence of reaction orders on BDs is studied. Subsequently adiabatic temperature diagrams (ATDs) with arbitrary reaction orders are innovatively plotted. Finally, the practical applications based on θMTSR criterion, constructed BDs and ATDs are discussed. Classification and optimization procedures for this kind of reaction are proposed, and especially a standalone desktop application program (app) is exploited to let users easily execute these two algorithms. A case study is also shown to verify the developed standalone desktop app.
