“…Most of the earlier reported studies were performed on model gasoline of binary or ternary systems containing one sulfur containing species and another hydrocarbon compound 10–13,19,21,27,35–39 . In these studies, experimental results of different binary or ternary model systems were compared to analyze the effects of different hydrocarbons or sulfur‐containing compounds present in gasoline.…”

“…In these studies, experimental results of different binary or ternary model systems were compared to analyze the effects of different hydrocarbons or sulfur‐containing compounds present in gasoline. In some of the studies, n ‐hexane, n ‐heptane, n ‐octane, and n ‐nonane were taken as model gasoline to understand the effects of the average molecular weight of hydrocarbons present in gasoline 10,11,36 . Similarly, the performance of the pervaporation process was compared for n ‐octane, n ‐heptane iso‐octane, 1‐octene, 1‐heptane, and toluene containing model gasoline to analyze the effect of different functional groups present in the gasoline 10–13,36 …”

Analyzing the effects of feed characteristics and membrane transport properties are important for designing the industrial‐scale pervaporative desulfurization plants. In this study, a new method to analyze the effects of feed composition and membrane characteristics has been proposed, where these properties are represented by average vapor pressure and average permeance coefficient. Spiral wound module geometry is used in this study for more realistic industrial‐scale predictions. Results suggested that module performance in terms of stage cut and enrichment factor improved with increasing selectivity of the membrane. However, this effect was profound at lower selectivity (<5) and became negligible at higher selectivity (>10). Moreover, results also depicted that the increase in feed temperature increased enrichment factor when selectivity was low (<2.5), but this trend was reversed when selectivity was greater than 2.5. At a constant membrane selectivity, an increase in permeability reduced the enrichment factor. Thus, membrane selectivity should improve along with membrane permeability for better results. The pervaporation process was found more beneficial for removing highly volatile low molecular weight sulfur‐containing compounds. Finally, feed channel temperature drop and permeate channel pressure drop followed the trend of stage cut in all simulations. Therefore, the lower stage cut may improve module efficiency.
