ABSTRACT

I. AMMONIA STORAGE Anhydrous ammonia is stored either in refrigerated atmospheric pressure storage tanks or in pressurized spheres and vessels commonly called "bullets." Large-capacity storage systems are normally refrigerated atmospheric pressure storage tanks. These are usually located at production plant sites and in the North American hemisphere at central storage terminals along several pipeline distribution systems. Pressurized or atmospheric temperature storage (bullets and spheres) are usually located at retail outlets and are much smaller in size. Due to the seasonal nature of the ammonia fertilizer market, ammonia is usually stored as a liquid at near-atmospheric pressure in large refrigerated storage tanks.
