VOCs from storage tanks

Because nonattainment areas still exist, especially in urban areas, the 1990 CAAA contain new and more stringent requirements for such areas. The ambient air quality standards for ozone are of particular concern. Controls include tighter standards on emissions from motor vehicles, use of cleaner fuels, and additional controls on industrial facilities. One of the biggest impacts on the chemical industry is more stringent requirements for minimizing the emission of volatile organic compounds (VOCs). This can include process emissions as well as emissions from storage tanks. 

Eliminate use of open ponds - Open ponds used to cool, settle out solids and store process water can be a significant source of VOC emissions. Wastewater from coke cooling and coke VOC removal is occasionally cooled in open ponds where VOCs easily escape to the atmosphere. In many cases, open ponds can be replaced with closed storage tanks.

The MVS technology is commercially available and was used to remediate soil contaminated with VOCs from a leaking underground storage tank at a Superfund site in upstate New York. The MVS technology was selected to remediate this site over bio venting and soil vapor extraction systems. 

Approximately 50% of US drinking water supplies are drawn from groundwater, and of these about 25% have been detected with VOCs above the Maximum Contaminant Level [73], Sources of contamination include agriculture and industry, hazardous waste disposal, underground storage tanks, and accidental spills. The organic contaminants of particular concern are chlorinated aliphatic and aro-... 

The main advantages of post-polymerization treatments are that they can be carried out either in the polymerization reactor or in the storage tank, and no additional equipment is needed. However, only the polymerizable residual volatiles can be eliminated, and in some cases new VOCs are produced from secondary reactions. Thus, formaldehyde is formed when sodium sulfoxylate formaldehyde is used as the reductant [66] and acetone and fert-butanol are formed when tert-butyl hydroperoxide is used as the oxidant [67]. In addition, inorganic water-soluble initiators may be deleterious to both stability and water sensitivity of the film formed with the latexes.
