WebIt was concluded that the most influential parameter for the permeation is the diffusion coefficient of the gases. The permeability and selectivity decrease as the operating pressure and PEG content are increased. Furthermore, the results showed that the addition of 5 wt% of PEG into PC increases the CO2/CH4 selectivity from 26.6 +/- 0.99 to 40 ... WebÜbersetzung im Kontext von „odor-intensive gases“ in Englisch-Deutsch von Reverso Context: The effect of the permeation gets more relevant to plant operation because parallel to the methane permeation, a release of odor-intensive gases such as ammonia and hydrogen sulfide also takes place by permeation through the membranes of the plants …
