In a process producing KNO3 salt, 1000 kg/h of a feed solution containing 10 wt% KNO3 is fed to an evaporator, which evaporates some water at 422 K to produce a 50 wt% KNO3 solution. This is then fed to a crystallizer at 311 K, where crystals containing 98 wt% KNO3 are removed. The saturated solution containing 37.5 wt% KNO3 is recycled to the evaporator. Calculate the amount of the recycle stream R in kg/h and the product stream of crystals P in kg/h.
