An electric power plant consumes 2.5 million gallons per day of cooling water. To control bacterial growth (slime), 2.0 mg/L of chlorine (measured as Cl2) is injected into the make-up water fed to the system. If the specific gravity of liquid chlorine is 3.21, what volume of liquid chlorine must be stored in order to maintain a 30-day supply?
If the plant uses sodium hypochlorite instead, what volume of NaOCl will be needed? Assume that the dry density of NaOCl is 1.2 kg/L and that 1 mg/L of dissolved NaOCl is equivalent to 1 mg/L of dissolved Cl2.
Note: 1 gal = 3.78 LYou have a contaminated air stream containing 1000 ppmV of toluene and you decided to incinerate to a DRE of 99.9%. You are using butane as fuel to reach the temperature and consider the lean toluene has no heating value. Determine how much butane would you need to burn 1000 cft of contaminated air steam. Consider no heat loss in the incinarator. (b) Show that presence of toluene does not improve fuel efficiency for any practical purpose.
