    What is a Gas Flow Rate? - Definition from Corrosionpedia

    11/8/2014· Gas flow rate is important, for example, in welding a uniform flow of gas is needed to shield the molten metal by blanketing it properly to avoid atmospheric contamination, which can lead to increased levels of oxidation or even porosity of the finished weld.

    In natural gas flow, pressure and temperature changes (P-T trace) may cause formation of a liquid phase owing to partial condensation of the gaseous medium. Retrograde phenomenon — typically found in multi-component hydrocarbon systems — takes place by allowing condensation of the gas phase and liquid appearance even under expansion of the flowing stream.

    A natural gas liquid with a low vapor pressure compared with natural gasoline and liquefied petroleum gas.Condensate is mainly composed of propane, butane, pentane and heavier hydrocarbon fractions. The condensate is not only generated into the reservoir, it is also formed when liquid drops out, or condenses, from a gas stream in pipelines or surface facilities.

    15/9/2013· Therefore, the proposed mass transfer approach is used in this section to predict the condensation rate when the natural gas is contaminated with both H 2 S and water vapor. Evidently, the current binary approach may not be able to consider the interaction between the condensed water and liquid hydrogen sulfide during the condensation processes.

    "Net" condensation means that the condensation rate exceeds the evaporation rate causing liquid water droplets to form. On the other hand, assuming you have some liquid water present to begin with, "net" evaporation, which means that the evaporation rate exceeds the condensation rate, causes liquid water droplets to shrink (or disappear altogether), or puddles on the ground to dry up, etc.
