Abstract
The current study looks into the batch reactor’s sulfonation reaction’s safety features. Acetanilide, thionyl chloride, and chlorosulphonic acid are used in the sulfonation reaction under consideration to generate acetyl sulphonyl chloride as well as by-products such HCl and SOx. Steam starts the process, which is exothermic in nature. Water is then chilled to maintain a temperature of 50°C and a pressure of one atmosphere. The Hazard and Operability (HAZOP) analysis was carried out initially, followed by Fault Tree Analysis (FTA), Event Tree Analysis (ETA), and Bow-Tie Analysis (BTA), in light of the safety concerns related to the reaction in question.
The techniques used assisted in identifying the inherent dangers associated with this intricate procedure. Methodically examining the process parameters, the HAZOP analysis looks for variations in the process that could result in risks like uncontrollable reactions or operational failures.
. The findings of the HAZOP study were incorporated into the fault tree, event tree and bowtie by considering reactor failure chances as the top event. The proposed fault tree had 17 intermediate events, and 30 basic events. Critical parameters such as temperature and pressure have a significant impact on the process. For example, temperatures above 150°C have the potential to cause thermal runaway and concurrent overpressure events. The current work contributed to ensuring the efficiency, dependability, and safety of the sulfonation reactions in batch processes by employing a mix of risk assessment tools.
