“…Additionally, the slope of i-pentane and n-pentane was in the range of 1.03-1.24 (Fig. 8b), which was larger than those related to oil and natural gas operations (0.82-0.89) (Gilman et al, 2010(Gilman et al, , 2013, but less than those measured for liquid gasoline and fuel evaporation (>1.5) (Conner et al, 1995;McGaughey et al, 2004;Watson et al, 2001;Zhang et al, 2013b). The ratios of i-pentane/n-pentane indicated that the VOCs originated from the mixed sources of NG and fuel evaporation in this study.…”

“…The i-pentane is a key tracer of gasoline evaporation due to its high abundance (Gentner et al, 2009;Zhang et al, 2013b). The ratios of i-pentane to n-pentane is useful to identify the potential sources including NG (0.82-0.89), liquid gasoline (1.5-3.0), fuel evaporation (1.8-4.6), and vehicle emission (2.2-3.8) (Harley et al, 2001;McGaughey et al, 2004;Russo et al, 2010;Gilman et al, 2013).…”

“…The gasoline evaporation profile holds high proportions of i-pentane, trans-2-pentene, cis-2-pentene, benzene, and toluene (Liu et al, 2008b;Zhang et al, 2013b). The i-pentane is a key tracer of gasoline evaporation due to its high abundance (Gentner et al, 2009;Zhang et al, 2013b).…”

Abstract. Oil and natural gas are important energy supply around the world. The exploring, drilling, transportation, and processing in oil-gas regions can release abundant volatile organic compounds (VOCs). To understand the atmospheric behaviors of VOCs in such region, the fifty-six VOCs designed as the photochemical precursors by the United State 15Environmental Protection Agency were continuously measured for an entire year (September 2014-August 2015) by a set of on-line monitor system at an oil-gas station in northwest China. The VOC concentrations in this study were 1-50 times higher than those measured in many other urban and industrial regions. The VOC compositions were also different from other studies with alkanes contributing up to 87.5% of the total VOCs in this study. According to the propylene-equivalent concentration and maximum incremental reactivity method, alkanes were identified as the most important VOC groups to the ozone 20 formation potential. The photochemical reaction, meteorological parameters (temperature, relative humidity, pressure, and wind speed) and boundary layer height were found to influence the temporal variations of VOCs at different time scales. The positive matrix factorization analysis showed that the natural gas, fuel evaporation, combustion sources, oil refining process, and asphalt contributed 62.6%, 21.5%, 10.9%, 3.8%, and 1.3%, respectively to the total VOCs on the annual average. Clear temporal variations differed from one source to another was observed, due to their differences in source emission strength and 25 the influence of meteorological parameters. Potential source contribution function and contribution weighted trajectory models based on backward trajectories indicated that five identified sources had similar geographic origins. Raster analysis based on CWT analysis indicated that the local emissions contributed 48.4%-74.6% to the VOCs. This research filled the gaps in understanding the VOCs in the oil-gas field region, where exhibited different source emission behaviors compared with the urban/industrial regions. 30

“…Zhang et al, 2012). Moreover, the ratios of trans-2-butene to cis-2-butene from different emission sources are within a narrow range: they are 1.13-1.37 from gasoline evaporation (Zhang et al, 2013b), 1.2-1.45 from gasoline vehicle exhaust (Liu et al, 2008b;Guo et al, 2011), 1.46 from biofuel burning and 0.8 from agriculture residue burning (Andreae and Merlet, 2001), and 1.88 from pine combustion (Schauer et al, 2001).

“…Propane, n-butane, and i-butane are major components of LPG leakage or combustion (Blake and Rowland, 1995;Barletta et al, 2002). Gasoline evaporation would contribute substantially to ambient i-pentane (Zhang et al, 2013b). Benzene, as a carcinogenic compound forbidden to be used in industry, was mainly from automobile exhausts in urban area (Zhao et al, 2004;Barletta et al, 2008;Tang et al, 2008) and mainly from biomass burning in rural areas (Holzinger et al, 2001).…”

Gasoline vapour emission is hazardous to both human health and the ecosystem and also results in capital loss, altogether revealing the necessity of its recovery. Some ZIF‐8–Pebax flat nanocomposite membranes were fabricated by the method of solution casting and used for gasoline vapour recovery as represented by n‐hexane vapour/nitrogen separation. Microporous ZIF‐8 nanoparticles were synthesized and characterized by Fourier transform infrared (FTIR) and Brunauer–Emmett–Teller (BET) analysis. BET results revealed specific surface area, total volume, and average pore diameter of 940.8 m2 · g−1, 0.36 cm3 · g−1, and 1.54 nm, respectively. Pure nitrogen and n‐hexane vapour/nitrogen gas mixture permeabilities were measured through the membranes. There was a decline in both permeation rate and selectivity up to 5.0 wt.% of ZIF‐8 loading and the next increment at their higher loadings to considerably more values that the pristine membrane. The maximum n‐hexane vapour permeability and selectivity at 10.0 wt.% loading of ZIF‐8 nanoparticles, the feed flow rate of 173 mL · min−1, and permeate side pressure of −200 mbar were observed as 280.1 Barrer and 106.7, respectively, revealing 60.0% and 36.9% improvements compared with those of the pristine Pebax membrane. Observed 86%–92% n‐hexane vapour recovery approves the successful application of the ZIF‐8–Pebax nanocomposite membranes for n‐hexane/nitrogen separation. The long‐term separation performance of 5.0 wt.% ZIF‐8 loaded nanocomposite membrane was improved by 76.5% compared with that of the pristine Pebax membrane.
