The state of air with dry bulb temperature 21 o C and relative humidity 50% is indicated in the Moliier chart below: From the Mollier chart the enthalpy of the moist air is approximately 40 kJ/kg. Mollier Charts Mollier Charts (Pressure-Enthalpy with constant Temperature, Density and Entropy Lines) Mollier diagram is a graphical representation of the thermodynamic properties and states of materials involving "Enthalpy" on one of the coordinates. Mollier diagrams are named after Richard Mollier. Typical mollier diagram Figure 4-8 can be used to get a quick approximate solution for the temperature drop of a natural gas stream. For example, if the initial pressure is 4,000 psi and the final pressure is 1,000 psi, AP is 3,000 psi and the change in temperature is 80°F. A Series of Enthalpy-entropy Charts for Natural Gases. Get PDF. Abstract. Enthalpy-entropy diagrams are presented for natural gasses of 0.6, 0.7, 0.8,0.9, and 1.0 gravity over the pressure range of 5 to 10,000 lb. per sq. in. andtemperature range of 32 degrees to 700 degrees Fahrenheit.

## The curve on the left below shows a typical phase diagram for natural gas. The Y axis indicates pressure and the X axis indicates temperature. When everything is operating properly, the gas is in the vapor region. The dew point curve (red curve) indicates where the liquids will begin to condense.

Mollier Diagrams. Compressor performance cannot be accurately predicted without detailed knowledge of the behavior of the gas or gases involved. Mollier diagrams are readily available for most pure gases at “conventional” pressures and temperatures. However, in cryogenic areas or at very high pressure, some gas behaviors are difficult to predict. The Mollier diagram is a variant of the psychrometric chart. Transform between Mollier diagram and psychrometric chart; Example - How to use the Mollier Chart. The state of air with dry bulb temperature 21 o C and relative humidity 50% is indicated in the Moliier chart below: From the Mollier chart the enthalpy of the moist air is approximately The charts indicatedirectly the work requirement and temperature rise for adiabatic compression ortemperature change for free expansion of natural gases.
