Balance de materia a un sistema evaporador-cristalizador (cristalizar KNO3)

In a process that produces KNO, 1000 kg/h of a solution containing 20% ​​KNO is fed. This solution enters an evaporator where water is removed to produce a 50% KNO solution. The solution is then introduced into a crystallizer at 38°C, and crystals containing 96% KNO are obtained. The mother liquor exits with 37.5% KNO and is recirculated to the evaporator. Calculate the amount of recirculated stream and the amount of crystals produced.
