  • Q1. What is hydrogenation. Which catalyst use How to vent hydrogen gas What do you know about PRV What is vacuum What is vacuum distillation What is capacity of cooling tower and chilling plants
  • Ans. 

    Hydrogenation is a chemical reaction that adds hydrogen to a molecule. Catalysts like nickel, palladium, and platinum are commonly used. Hydrogen gas is vented through a pressure relief valve (PRV). Vacuum distillation is a process that separates components based on their boiling points under reduced pressure. Cooling tower and chilling plant capacity depends on the specific application.
