WebNitrogen purity is generally expressed as a percent, such as 99% Nitrogen (which means 1% Oxygen with the balance nitrogen and other inert gases). In some high purity cases, … WebSep 26, 2024 · The temperature must be lowered and/or the pressure must be raised to liquefy nitrogen. Critical Temperature and Pressure Once a sufficiently low (T/P) ratio is reached, the gas changes to liquid. For every temperature, there is a minimum pressure required to establish and maintain the liquid.
WebApr 3, 2024 · Energy consumption values for phosphate and potash fertilizer are estimated at 5,600 BTUs per pound of phosphate (P2O5) and 4,700 BTUs per pound of potash (K2O). Energy use for the production of fertilizer is not the entire story. Energy is also required for transporting fertilizers to the dealer and then to the farm and for application. WebSpecific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: #q = m * c * DeltaT#, where #q# - the amount of heat supplied; #m# - the mass of the substance; #c# - the respective substance's specific heat; #DeltaT# - the change in temperature. So, if we want to …
