A spent sulfuric acid stream from a nitration process consists of 30. wt% H2SO4 in water. This dilute acid is to be strengthened by the addition of a stream of 90. wt% sulfuric acid, and a stream of 90. wt% nitric acid (HNO,). The product stream is to consist of 40. wt% sulfuric acid and 40, wt% nitric acid. The resulting mixture is produced at 100. Ibm/min. Calculate the quantities of spent and concentrated acids that should be mixed to produce the fortified acid mix. Perform a DOF analysis to show that a solution is possible. You must DRAW A DIAGRAM and SHOW YOUR WORK. Variables Stream System Constraints Flow |Composition Performance Material Balances Total Total

Question
A spent sulfuric acid stream from a nitration process consists of 30. wt% H2SO4 in water. This dilute acid is to be strengthened by the addition of a stream of 90. wt% sulfuric acid, and a stream of 90. wt% nitric acid (HNO3). The product stream is to consist of 40. wt% sulfuric acid and 40. wt% nitric acid. The resulting mixture is produced at 100. Ibm/min. Calculate the quantities of spent and concentrated acids that should be mixed to produce the fortified acid mix. Perform a DOF analysis to show that a solution is possible.
