Options for VOC reduction in a regenerative thermal oxidizer (RTO)
- Process Combustion Corp. (PCC), Pittsburgh, PA (United States)
Environmental regulations stemming from the 1990 Clean Air Act amendments are requiring treatment of high volume but relatively dilute VOC contaminated air and waste gas streams. Because of its low operating costs, Regenerative Thermal Oxidation (RTO) has emerged as the preferred treatment method for many of these streams. In the past, this technology usually required multiple (3 or more) beds of heat sink packing. However, some new units are being supplied with only two beds. Consequently, capital costs are lower. This paper describes test data from a unique twin bed RTO. Data for two different types of heat sink material will be presented, random packing and structured packing. The effect of cycle time, bed length, and packing type on thermal efficiency will be described. A cost comparison is included showing the effect of packing type on both capital and operating costs for various RTO sizes.
