(Solved): 1- Hyrogenation reaction which is a highly exothermic reaction, takes place in a fixed-bed reactor ...
1- Hyrogenation reaction which is a highly exothermic reaction, takes place in a fixed-bed reactor cooled with alcohol \& water mixture circulated around it. There are 1 liquid (nitrobenzene) phase and 1 gas (hydrogen) phase fed to the reactor operating at the temperature of and 5 atm pressure. a) Explain the hazards and the risks by considering the type of the reactor, chemicals, cooling medium and the operating conditions of the reaction. b) Discuss and compare the chemical process safety strategies (inherent, active, passive,......) should be applied to reduce the hazards and risks. c) Which strategy should be used for safer process? Give the reasons of your choice. e: Prepare a table for each hazard and risk; and give your precautions as
Expert Answer
a) Hazards and risks associated with the hydrogenation reaction in the fixed-bed reactor are: Fire and explosion hazard due to the highly exothermic nature of the reaction and the presence of flammable hydrogen gas. Toxicity hazard from the nitrobenzene liquid phase, which is a skin and respiratory irritant and can cause methemoglobinemia (a blood disorder). Thermal hazard due to the high...
