Fertiliser Technology In an ammonia plant, the purge off is essential to Maintain inert gas concentration within a limit Remove excess poisonous gases Maintain H₂ : N₂ ratio at 3 :1 Remove uncondensed ammonia vapour Maintain inert gas concentration within a limit Remove excess poisonous gases Maintain H₂ : N₂ ratio at 3 :1 Remove uncondensed ammonia vapour ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology In ammonia synthesis (N₂ + 3H₂ = 2NH₃), there is a decrease in total volume, hence to get high equilibrium conversion, the reaction should be carried out at Low pressure Very high temperature Atmospheric pressure; as the pressure has no effect on conversion High pressure Low pressure Very high temperature Atmospheric pressure; as the pressure has no effect on conversion High pressure ANSWER DOWNLOAD EXAMIANS APP
