“…Moreira dos Santos et al (2004) sampled 36 VOCs with activated charcoal sorbent tubes from the thermoelectric stack of coal-fired power stations in Brazil, and found that benzene held the highest concentration. Tsai et al (2008) measured the 68 VOCs from an integrated iron and steel plant located in southern Taiwan, including coke making, sintering, hot forming and cold forming. Exhaust gases were sampled from the stacks and analyzed by the US EPA Method 18 integrated bag method, and it was found that toluene, 1,2,4-trimethylbenzene, isopentane, m,p-xylene, 1-butene, ethylbenzene, and benzene were the predominant VOC species in these processes.…”

“…The EFs of VOCs of the iron and steel industry were mainly gained from domestic research (Lei, 2008;Tsai, 2008). In general, the sintering process, the heating furnace, and the BF are the major VOCs sources.…”

“…Some emission inventories estimate the emissions of the regional iron and steel industry (Zheng et al, 2009;Tang et al, 2012); some take processes into account, such as the Huabei region emission inventory (Zhao et al, 2012) and national key iron and steel plants emission inventory (Lei et al, 2008). Moreover, there have been many studies measuring or investigating the emissions of iron and steel equipment, including SO 2 , NO x , PM, VOCs, PCDD/Fs (Gong et al, 2008;Lei et al, 2008;Tsai et al, 2008;Lu et al, 2009;Ma et al, 2009;Zou et al, 2012;Yang et al, 2013). In this work, we developed an emission inventory of major air pollutants from China's iron and steel industry based on detailed activity level (provincial production, iron and steel plants location, production technology, production equipment, emission control facilities and so on) for 2012, and we tentatively predict future emissions in 2030 through scenario analysis, considering different levels of iron and steel production and control measures; existing and possible future regulations were taken into account as well.…”

China is the largest iron and steel producing and consuming country in the world, which leads to enormous quantities of emitted air pollutants. Direct emissions of air pollutants from the iron and steel industry in China were estimated by developing a process and technology-based methodology using information of the proportion of pig iron, crude steel, and rolled steel produced from different processes and technology. Emissions of sulfur dioxide (SO 2 ), nitrogen oxides (NO x ), particulate matter (PM), volatile organic compound (VOCs), and dioxin (PCDD/Fs) were estimated for the year 2012, and future emissions of major pollutants (SO 2 , NO x , TSP) were projected up to 2030 based on technology developing trends and emission control policies. According to the estimation, 2222 kt of SO 2 , 937 kt of NO x , 1886 kt of TSP, 555 kt of PM 2.5 , 254 kt of VOCs, 618 g I-TEQ of PCDD/Fs was produced in China in 2012. Sintering produced 72.4% of SO 2 , 49.4% of NO x , 22.5% of TSP, 24.0% of PM 2.5 , 69.6% of VOCs and 98.0% of PCDD/Fs, which is the main emission source. Through faithful implementation of closing down outdated production and emission control policies, approximately 77%, 49%, 67% and 64% of SO 2 , NO x , TSP and PCDD/Fs emissions, respectively, could be further reduced in 2012. Emissions in 2020 and 2030 of iron and steel sectors were predicted applying scenario analysis. The removal potential for SO 2 and TSP is larger than NO x by improvement of removal facilities, and southwest, northwest, and north China has the largest SO 2 , NO x , TSP and PCDD/Fs removal potential respectively.

“…In some industrial processes a significant amount of aromatic compounds emissions are formed. For example in iron and steel industry (included coke making, sintering, hot forming, and cold forming) major emissions are aromatic compounds with 46%-64% of total emissions [191]. Aromatic VOCs are also an origin for the problems caused by urban city air.…”

Abstract:The treatment of volatile organic compounds (VOC) emissions is a necessity of today. The catalytic treatment has already proven to be environmentally and economically sound technology for the total oxidation of the VOCs. However, in certain cases, it may also become economical to utilize these emissions in some profitable way. Currently, the most common way to utilize the VOC emissions is their use in energy production. However, interesting possibilities are arising from the usage of VOCs in hydrogen and syngas production. Production of chemicals from VOC emissions is still mainly at the research stage. However, few commercial examples exist. This review will summarize the commercially existing VOC utilization possibilities, present the utilization applications that are in the research stage and introduce some novel ideas related to the catalytic utilization possibilities of the VOC emissions. In general, there exist a vast number of possibilities for VOC OPEN ACCESSCatalysts 2015, 5 1093 utilization via different catalytic processes, which creates also a good research potential for the future.
