Unformatted text preview: production rate of dried pulp and the rate of removal of water (kg/hr)? Dried pulp =2534 kg/hr Water removal = 990 kg/hr The Spent acid from a nitrating process contains 43 wt% H 2 SO 4 , 36 wt% HNO 3 ,and the balance H 2 O. This acid is to be strengthened for re-use by the addition of concentrated sulfuric acid (91 wt% H 2 SO 4 , balance H 2 O) and concentrated Nitric acid (88 wt% HNO 3 , balance H 2 O). The resulting mixed acid is to contain 40 wt% H 2 SO 4 and 43 wt% HNO 3 . Calculate the quantities (kg) of spent and concentrated acids which should be mixed to yield 1000 kg of mixed acid. Spent acid = 608.5 kg Sulfuric acid = 151.8 kg Nitric acid = 239.7 kg...
