Abstract
AbstractThe aim of this study is to perform process hazard analysis and safe process design for the prevention of process accidents in solid propellant mixers. Propellant mixers inherently entail a high level of risk due to the nature of the propellant production process. Processes carried out using propellant mixers pose significant risks when they lack a design that incorporates current technologies. Information related to chemicals, process equipment, and automation systems were compiled in PSI. Hazard and operability (HAZOP) and fault tree analysis (FTA) were performed to identify the potential hazards of the process and evaluate the probabilities. Sample facility maintenance data and values in databases were used for the process equipment's probability of failure on demand, and the TESEO method was used to quantify human errors. It was determined that the potential accident scenarios had similar failure probabilities. The use of automation was very important to eliminate the risks that threaten human life.
