SOHIO insures stable storage of 83% ammonium nitrate with two 35,000 barrel tanks of ALCOA ALUMINUM Aluminum will not render ammonium nitrate unstable! That's why Sohio Chemical Company chose Alcoa® Aluminum for two special 35,000 barrel tanks used to store 8 3 % ammonium nitrate solutions produced in a new $17-million petrochemical plant at Lima, Ohio. Now in full-scale production, the plant yields over 300,000 tons of ammonia and derivatives yearly. Like so many other petrochemical producers, Sohio has found that Alcoa Aluminum provides an ideal answer to the problem of better, cheaper storage and handling of ammonium nitrate and nitrogen solutions. And the superior corrosion resistance of aluminum gives it extra-long service life under constant exposure to chemicals and plant atmospheres normally corrosive to most metals. That makes Alcoa Aluminum the least expensive material to solve storage and handling problems when product protection and corrosion resistance are vital. The superior storage and handling performance of Alcoa Aluminum has been proved on-the-job in such
diverse applications as these: fertilizer solution storage tanks, nitrogen chilling exchangers, prilling towers, tank cars, piping and drums. A new Alcoa book, Process Industries Applications of Alcoa Aluminum, contains 80 pages packed with performance and design data.
