how much nh3 joints for gas measurement

Aqueous NH3 solutions are characterized by relatively high NH3 vapor pressures that prevent the mass transfer of NH3 from gas to liquid phase. Commonly NH3 is scrubbed with an aqueous acid solution. Sulfuric acid or phosphoric acid are often chosen because of their own relatively low vapor pressure.

  • NH3 Precision Anhydrous Ammonia Application for Systems

    Jan 27, 2015 · Anhydrous ammonia is stored and transported as a liquid. To maintain NH3 as a liquid it must be kept below –28°F or maintained under pressure. If the temperature of the NH3 increases above –28°F some of the liquid changes to a gas as the NH3 begins to boil. Application equipment typically uses tank pressure to deliver NH3 to the soil.
