Fertiliser Technology Prilling of urea should be accomplished (in a sprayer) just above the melting point of urea with minimum of retention time, otherwise it will result in Non-spherical prills Low bulk density product Biuret formation Substantially wet non-flowing and sticky product Non-spherical prills Low bulk density product Biuret formation Substantially wet non-flowing and sticky product ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Yield of urea can be increased with excess ammonia and higher pressure & temperature, but because of __________ this is normally not done. Increased cost of equipment High corrosion rate Increased biuret formation All of these Increased cost of equipment High corrosion rate Increased biuret formation All of these 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 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 Very high temperature Low pressure High pressure ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Ammonium nitrate (is mixed with limestone) is not used as fertiliser as such, because It is a liquid at room temperature It is highly acidic in nature It is hygroscopic and explosive in nature Its nitrogen content is very less It is a liquid at room temperature It is highly acidic in nature It is hygroscopic and explosive in nature Its nitrogen content is very less ANSWER DOWNLOAD EXAMIANS APP
