Fertiliser Technology Fertiliser plants get their N₂ requirements By fractionation of liquified air From coal gas (coke oven gas) From producer gas By dissociating oxides of nitrogen By fractionation of liquified air From coal gas (coke oven gas) From producer gas By dissociating oxides of nitrogen 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 High pressure Low pressure Atmospheric pressure; as the pressure has no effect on conversion Very high temperature High pressure Low pressure Atmospheric pressure; as the pressure has no effect on conversion Very high temperature ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Multistage operation (as in the case of catalytic oxidation of SO₂) is not carried out for NH₃ synthesis, because of Higher pumping cost High cost of the high pressure vessel used for the reactor Chances of entrainment and disturbance of catalyst bed Comparatively higher pressure drop Higher pumping cost High cost of the high pressure vessel used for the reactor Chances of entrainment and disturbance of catalyst bed Comparatively higher pressure drop ANSWER DOWNLOAD EXAMIANS APP
