HEALTH EFFECTS of AMMONIA - TFI
www.tfi.orgtemperature, ammonia is a colorless, pungent-smelling gas and is lighter than air. At minus 28 degrees fahrenheit (-33 degrees celsius), ammonia becomes a liquid. Ammonia easily dissolves in water. In this form, it is also known as liquid ammonia, aqueous ammonia or ammonia solution. In water, most of the ammonia changes to ammonium ions, nH 4 +.
Introduction to Ammonia Production - AIChE
www.aiche.orgthe total annual production of synthesized ammonia was just over 300,000 m.t. Thanks to chemical engineering break-throughs, one modern ammonia plant can produce more than 750,000 m.t./yr. Approximately 88% of ammonia made annually is con-sumed in the manufacturing of fertilizer. Most of the remain-der goes into the production of formaldehyde.

tannerind.comAnhydrous Ammonia liquid weighs approximately 5 pounds per gallon, at 60°F. A pound of liquid Anhydrous Ammonia will generate 22.5 SCF of ammonia vapor and 45 SCR of dissociated ammonia gas. A storage tank is usually considered to have an 85% usable capacity. (A 15% vapor space must always be maintained when filling, to allow for expansion).
