we are manufacturer and exporters of ammonia tank, ammonia storage tanks, ammonia gas tanks, anhydrous ammonia tanks and other all gas storage tanks and transport tanks . Ammonia (NH3) is pungent, colorless compound. Anhydrous (water-free) ammonia is easily liquefied under pressure and is extremely soluble in water. Ammonia is the precursor to most nitrogen-containing compounds. Virtually all synthetic nitrogen compounds are derived from ammonia, including nitric acid, which is used in the production of fertilizers, explosives, and many organo-nitrogen compounds. It is easily liquefied by compression or cooling for use in refrigeration and air-conditioning equipment. Because of its many applications, ammonia is one of the most highly produced inorganic chemicals, yet it is both caustic and hazardous. OSHA has set a limit of 25 ppm during an eight-hour shift. EPA regulations (40 CFR 68) require facilities with more than 10,000 pounds of ammonia to submit a risk management plan, including a hazard assessment, a prevention program, and emergency response program.
