Variation of Natural Gas Viscosity with Temperature, Pressure, and Relative Density
December 20, 2022
|
Tip of the Month
In general, gas viscosity is used in fluid flow pressure drop calculations, detailed heat exchanger calculations, and droplet settling calculations for separation. It is also used for trouble shooting and equipment sizing.
In this Tip of The Month (TOTM), several options/methods for estimating viscosity of lean sweet natural (hydrocarbon) gases as ...

Determining Traces of Methanol in the Gas Sweetening Process - Updates
October 1, 2022
|
Tip of the Month
The July 2016 tip of the month (TOTM) considered the presence of methanol in the sour gas stream and determined the quantitative traces of methanol ending up in the sweet gas, flash gas and acid gas streams. To achieve this, the tip simulated a simplified MDEA gas sweetening unit by computer. That tip also studied the effect of feed sour gas temper...
