Abstract
Volatile organic compounds (VOCs) are one of the most significant gaseous air pollutants due to their evident characteristics, which include high volatility, extreme toxicity, and low degradability. VOCs are receiving an increasing amount of interest. A large number of technologies have been explored and implemented in an effort to minimize VOC emissions. VOCs in the indoor environment, VOCs in the outdoor environment, VOCs in nature, and VOCs in the water supply are some of the several sources of emission that may be found today. There are several “end-of-pipe” solutions that can reduce VOC emissions; however, implementing them can raise facility costs, downtime, and/or maintenance. In this chapter, the common VOC removal treatment being discussed include thermal oxidation, catalytic oxidation, adsorption, and biotreatment. Meanwhile, recovery technologies are recommended by researchers because of the benefits they offer in recycling volatile organic compounds (VOCs) and lowering carbon emissions. The adsorption system is the most operationally adaptable and has the lowest life cycle cost. Changes in emission components or concentrations would necessitate significant modifications to the design. The biofilter has the minimum life cycle cost but the least operational flexibility and may necessitate a complete design modification if legislative requirements are drastically reduced. The most popular and efficient VOC removal approach is catalytic oxidation. However, the issues regarding high energy consumption must be addressed. The thermal oxidation system has the highest life cycle cost, but it is only somewhat adaptable in terms of its operational use. Should the flow rates of the process be altered, significant adjustments to the design will be necessary. However, each technological solution must be evaluated using key operational aspects to determine its overall success.
