Fertiliser Technology Multistage operation (as in the case of catalytic oxidation of SO₂) is not carried out for NH₃ synthesis, because of Comparatively higher pressure drop High cost of the high pressure vessel used for the reactor Higher pumping cost Chances of entrainment and disturbance of catalyst bed Comparatively higher pressure drop High cost of the high pressure vessel used for the reactor Higher pumping cost Chances of entrainment and disturbance of catalyst bed ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Lower temperature and large excess of ammonia in urea melt Does not effect biuret formation Decreases biuret formation Increases biuret formation Is undersirable Does not effect biuret formation Decreases biuret formation Increases biuret formation Is undersirable ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Fertiliser plants get their N₂ requirements By fractionation of liquified air From producer gas By dissociating oxides of nitrogen From coal gas (coke oven gas) By fractionation of liquified air From producer gas By dissociating oxides of nitrogen From coal gas (coke oven gas) ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Though kinetics of ammonia synthesis dictates the use of low temperature for high equilibrium conversion, yet it is kept moderately high (550°C), because at low temperature None of these Rate of reaction is very low Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel None of these Rate of reaction is very low Space velocity of gas is very low resulting in decreased conversion Very high pressure is required resulting in costly pressure vessel ANSWER DOWNLOAD EXAMIANS APP
