Gaseous ammonia and 50 wt% aqueous nitric acid solution are fed to a reactor in stoichiometric proportions where they react completely to form aqueous ammonium nitrate: nh3 + hno3 > nh4no3 the aqueous ammonium nitrate solution leaving the reactor is mixed with a recycle stream coming from a crystalliser. the mixed stream passes through an evaporator where some of the water is removed. the concentrated solution leaving the evaporator is saturated at 70°c and passes through a crystalliser and filter unit which produce anhydrous nh4no3 crystals at 20°c. the saturated nh4no3 solution at 20°c leaving the crystalliser/filter is recycled to be mixed with reactor product stream. the wet filter cake, containing 90 wt% nh4no3 crystals and the remaining saturated nh4no3 solution at 20°c is sent to a dryer where all of water is removed. for a production rate of 100.0 ton/day of anhydrous ammonium nitrate crystals, find - (a) the mass flow rate of the recycle stream (kg/h). (b) mass flow rate of the water evaporated in the evaporator and the dryer (kg/h). (c) if the water leaving the evaporator is condensed to be mixed with a concentrated nitric acid solution to make the feed solution of 50 wt% nitric acid what would be the mass composition of the concentrated nitric acid solution. comment on why it is important to recycle the water leaving the evaporator. data: temperature (°c) solubility of nh4no3 in water (g nh4no3/100 g water) 134.2 235.1 70
