Waste Gas Treatment

A new paraffin/surfactant/water emulsion (PSW) for volatile organic compounds (VOCs) controlling was prepared and its potential for VOCs removal was investigated. Results indicated that PSW-5 (5%, v/v) provided higher toluene absorption efficiency (90.77%) than the other absorbents used. The saturation pressure, Henry’s constant, and activity coefficient of toluene in PSW-5 were significantly lower than those in water, and toluene solubility (1.331 g·L−1) in the PSW-5 was more than 2.5 times higher than the value in water. Several factors potentially affecting the toluene absorption efficiency were systematically investigated. The results suggested that concentration and pH of PSW, absorption temperature, and gas flow rate all had a strong influence on the toluene absorption, but the inlet concentration of toluene had little effect on the toluene absorption. There were different absorbing performances of PSW-5 on different VOCs, and the ketones, esters, and aromatics were more easily removed by the PSW-5 than the alkanes. Regeneration and reuse of the PSW were possible; after 3 runs of regeneration the absorption efficiency of PSW-5 for toluene also could reach 82.42%. So, the PSW is an economic, efficient, and safe absorbent and has a great prospect in organic waste gas treatment.

Industrialization combined with Urbanization makes city an industrial center as well as a core pollution source, which becomes the key for present pollution treatment. In this paper, the relationship between was cost of waste gas treatment and industrial scale for a city is investigated. By regression analysis, its found that pollution treatment technology is no obviously different in main cities of China so far, rough pollution treatment is still the main treatment way which will be more efficient when the pollution treatment volume reaches some scale.

Treatment Application

With the increasingly serious environmental problems, China has adopted more and more strict industrial production emission policies. Haze pollutes the weather and limits the production of polluting enterprises have seriously affected the normal production process of the factory. The pollutants discharged in automobile manufacturing process are increasing, and the environmental pollution caused by automobile coating needs to be solved urgently. Because a large amount of solvent-based paint is used in the production process, the pollution caused by volatile organic compounds is difficult to avoid. RCO is a new technology in the field of automobile coating waste gas treatment. Application of RCO in automobile coating waste gas treatment is studied.
