Fertiliser Technology Multistage operation (as in the case of catalytic oxidation of SO₂) is not carried out for NH₃ synthesis, because of Chances of entrainment and disturbance of catalyst bed High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop Higher pumping cost Chances of entrainment and disturbance of catalyst bed High cost of the high pressure vessel used for the reactor Comparatively higher pressure drop Higher pumping cost ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Coal based fertiliser plants at Ramagundam (Andhra Pradesh) and Talchar (Orissa) Gasify coal to get hydrogen from coal gas Use coal as conditioner in fertiliser Use coal as filler in fertiliser Use coal for heating purpose Gasify coal to get hydrogen from coal gas Use coal as conditioner in fertiliser Use coal as filler in fertiliser Use coal for heating purpose 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 Very high temperature Low pressure High pressure Atmospheric pressure; as the pressure has no effect on conversion Very high temperature Low pressure High pressure Atmospheric pressure; as the pressure has no effect on conversion ANSWER DOWNLOAD EXAMIANS APP
