What temperature should ammonia be stored at?
around 60-70 ˚F
Any type of ammonia container should be kept in a cool, dry, temperature stable environment generally around 60-70 ˚F (15-50 ˚C).
What is the form of ammonia at normal temperature and pressure?
gas
NH3 boils at −33.34 °C (−28.012 °F) at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature. Household ammonia or ammonium hydroxide is a solution of NH3 in water….Ammonia.

What temperature is ammonia gas?
At atmospheric temperature and pressures, anhydrous ammonia is a pungent colorless gas. Anhydrous ammonia boils at -28°F and freezes to a white crystalline mass at -108°F. When heated above its critical temperature of 270.3°F, ammonia exists only as a vapor regardless of the pressure.
Is ammonia combustible or flammable?
flammable
Ammonia is flammable. Fire will produce irritating, corrosive, and/or toxic gases. Never direct water jet straight at liquid ammonia. For small fires use dry chemical or carbon dioxide.
How flammable is anhydrous ammonia?
Fire Hazard: Flammable gas. Ammonia concentrations in the range of 16-25% by volume in air can be ignited if heated to the auto- ignition temperature.
At what pressure is ammonia transported?
Ammonia gas turns into a liquid at 125 psi (862 kPa) and liquid ammonia is transported in pipelines. At the delivery point, hydrogen gas is liberated from ammonia.
At what pressure does ammonia liquify?
Also known as ammonia liquefied under pressure, anhydrous ammonia, moisture-free ammonia, NH3, etc. At temperatures below –33°C ammonia turns liquid at atmospheric pressure. Increasing the pressure by itself suffices to liquefy the gas: at 20°C a pressure of 7.5 bar is adequate.
What is the pressure of ammonia?
At atmospheric pressure, NH3 boils at -28°F. As the temperature rises, the vapor pressure increases rapidly. NH3 vapor will ignite under atmospheric pressure conditions at a minimum temperature of 1562°F, but only in the very limited range of 16 to 25 percent of NH3 vapor in air….Anhydrous Ammonia Basics.

What is standard pressure for ammonia?
Ammonia gas occupies a volume of 450 mL as a pressure of 720 mmHg.
At what temperature does ammonia explode?
between 270 and 282 K
1. Temperature ranges for which ammonia vapors are explosive in air increase with decreasing am- monia concentration in solutions. For example, ammonia vapors from the 28% solution in air form an explosive atmosphere between 270 and 282 K, whereas it is between 309 and 320 K for a 10% ammonia solution.
What is the critical temperature of ammonia?
Ammonia Critical point – Critical temperature : 132.4oC – Critical pressure : 112.8 bar. Ammonia Gas Density ( 1.013 bar at boiling point) : 0.86 kg/m3. Ammonia Gas Density ( 1.013 bar and 15oC (59oF)) : 0.73 kg/m3.
What is the boiling point of ammonia?
Ammonia Vapor pressure (at 21 o C or 70 o F) : 8.88 bar Ammonia Critical point – Critical temperature : 132.4 o C – Critical pressure : 112.8 bar Ammonia Gas Density ( 1.013 bar at boiling point) : 0.86 kg/m 3
What is the latent heat of vaporization of ammonia?
Ammonia Latent heat of vaporization (1.013 bar at boiling point) : 1371.2 kJ/kg Ammonia Vapor pressure (at 21oC or 70oF) : 8.88 bar Ammonia Critical point – Critical temperature : 132.4oC – Critical pressure : 112.8 bar Ammonia Gas Density (1.013 bar at boiling point) : 0.86 kg/m3
What are the requirements for exposure to ammonia gas?
>300 ppm: A fresh air supply system must be used (i.e. positive pressure self contained breathing apparatus). Skin Protection Requirements: Skin protection is required for exposure to liquid, mist, and > 1000 ppm of ammonia gas or vapors.
