Ammonia is very soluble in water, a saturated solution containing approximately 45% NH3 (weight) at the freezing temperature of the solution and about 30% (weight) at standard conditions. Ammonia dissolved in water forms a strongly alkaline solution of ammonium hydroxide, NH4OH. The univalent ...

liquid ammonia expands to850 timesits liquid volume at atmospheric pressure Thevapour pressure of ammoniais the pressure at which ammonia gas is inthermodynamic equilibrium with its condensed state. At higher pressures ammonia would condense . At this equilibrium condition the vapor pressure is thesatur...
Saturated Vapor PressureHuminIn this work we propose the use of peat as an alternative material to be used for the development of ammonia sensors. A thorough characterization of the material is carried out in order to ensure its feasibility as a source of an efficient sensor. Humin, which is...
The saturated vapor pressure Ps MPa in the temperature range from 193 to 400°K can also be calculated by the following formula [68]:(7)lgPs=(A−B·T−1−C·T+D·T2−E·T3)10−1,where: A, B, C, D and E are constants; A = 9.584586; B = 1648.6068; C = 1.638646·...
The materials of storage tanks are generally low alloy plates specially used for low alloy pressure vessels such as Q345R and 16MnDR. The design pressure is 60 ° C, which is the saturated vapor pressure of Liquid ammonia gas, and the volume is ...
In the case of high temperature, the saturated vapor pressure of Propane-Butane Mix is high, so the 16barg (inlet pressure)-24barg (outlet pressure) model is selected to meet the use environment when the temperature is high. Note: The unit of pressure is...
But the actual use temperature may not be normal at room temperature. Our country requires that the design should be no less than 50 degrees Celsius saturated vapor pressure. The design pressure for liquid ammonia containers should be 2.16MPa...
The current injection system utilized the storage pressure of ammonia. To achieve a high injection pressure, the ammonia tank was heated so as to increase the saturated vapor pressure, and the gaseous ammonia was siphoned of the top of the tank. The injection pressure was directly controlled by...
Ammonia -NH3- is a gas commonly used as a refrigerant in cooling systems. The gas is colorless with very sharp odor. In small concentrations the gas is detectable by smell. In high concentrations the gas is an immediatehazardto life. ...
