Grahic Jump Location
Schematic of a gas fuel system, showing the pressure drop in various devices. If the gas is not superheated sufficiently, its temperature will eventually fall below the dew point temperature.
Grahic Jump Location
Schematic of typical oil or gas platform fuel conditioning system
Grahic Jump Location
Comparison of a experimental data, a commercial code, and the presented code (dpcalc) for the dewpoint calculation of a binary methane-water system. Experimental data from Joffrion and Eubank 3.
Grahic Jump Location
Schematic of gas pipeline fuel delivery system with gas at greater than minimum superheat
Grahic Jump Location
Engine compressor discharge pressure (PCD) as a function of engine load
Grahic Jump Location
Enthalpy of the dewpoint must always be below the entahlpy of the fuel gas at inlet conditions. Gas composition is: methane 75.4%, ethane 13.8%, propane 5.25%, I-butane .86%, n-butane 1.12%, I-pentane 0.63%, n-hexane 0.21%, n-heptane 0.08%, n-octane .03%, n-nonane 0.01%, nitrogen 0.5%, carbon dioxide 1.86%, water 0.23%.
Grahic Jump Location
Dewline for different gas mixtures in a pressure (bar)-temperature (K) diagram. Gas composition is: methane 73.8%, ethane 8.2%, propane 3.23%, I-butane .28%, n-butane 0.78%, I-pentane 0.24%, n-pentane 0.18%, n-hexane 0.18%, Cxx 0.71%, nitrogen 0.93%, carbon dioxide 11.68%. Cxx represents either hexane (C6), octane (C8), or decane (C10). Despite the fact that Cxx represents only 0.71% of the gas, it has a significant impact on the dew point.
Grahic Jump Location
Dewpoint enthalpy for gas fuel and process path for adiabatic expansion starting with different degrees of superheat. Fuel gas composition is: methane 83%, ethane 8%, propane 3%, I-butane 0.3%, n-butane 0.8%, I-pentane 0.3%, n-pentane 0.3% n-hexane 0.4%, n-heptane 0.2%, n-octane 0.08%, n-nonane 0.02%, n-decane 0.01%, nitrogen 1.9%, carbon dioxide 1.69%.
