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 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 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 Space velocity of gas is very low resulting in decreased conversion Rate of reaction is very low None of these Very high pressure is required resulting in costly pressure vessel Space velocity of gas is very low resulting in decreased conversion Rate of reaction is very low None of these Very high pressure is required resulting in costly pressure vessel ANSWER DOWNLOAD EXAMIANS APP
