“…Actually, a number of solid–liquid reactions can also have serious consequences due to the massive reaction heat and dissolution heat. The dynamics of solid–liquid reactions in SBRs was first presented by Samoilenko et al In their study, they investigated the thermal explosion of solid–liquid reactions in a BR 22 and a SBR. 23 However, the mathematical model they proposed did not take into account the influence of dissolution, which can be an exothermic or endothermic process.…”

An exothermic reaction in a semibatch reactor can potentially cause thermal runaway due to evolved energy accumulation or a secondary reaction. This research aims to propose safety criteria for solid–liquid reactions in semibatch reactors. Simulation modeling was carried out to build thermal runaway criteria for solid–liquid reactions in semibatch reactors. A new model for the energy and mass balance of solid–liquid reactions was successfully established. Criteria for the safety boundary diagram and the temperature diagram were ameliorated for solid–liquid reactions. The results showed that the dissolution heat has a great influence on the thermal behavior of the reaction. Experiments to neutralize citric acid and sodium hydroxide were carried out to determine the critical parameters for the neutralization reaction using the temperature diagram criterion. The proposed criteria would be reasonably expected to provide some guidance for chemical process optimization and safety design for engineering.
