Fertiliser Technology Liquid ammonia is not used as such a fertiliser in tropical countries like India, because It will evaporate on spraying It is very costly Its N₂ content is very low It is not available It will evaporate on spraying It is very costly Its N₂ content is very low It is not available 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
