First, the vapor pressure and aqueous solubility of XPAHs within the same group exhibit a decreasing trend with increasing molecular weight except for X-Fle. In addition, for analytes that are replaced by the same halogen group, with increasing molecular weight and number of halogen substitutions ...

hydrocarbons such as ethane, propane, butane, along with higher molecular weight fractions. Water vapor, carbon dioxide, acidic gases, mercury, hydrogen sulfide, helium and nitrogen are also present in raw natural gas as impurities. A glycol dehydration unit is typically used for removing wate...
The third limitation of a simple porosity-controlled view of WVP properties, and the one of the most general importance, is that the transport of water through the barrier is assumed to be entirely due to molecular diffusion in the gas/vapour phase. It is often said that there may be a ...
