Abstract

The problem at a foam packaging plant in Texas was periodic spikes of expanded foam blowing agent to atmosphere. The amount of butane blowing agent released is a function of the thickness of the packaging foam desired. As the facility changed products on the multiple extrusion lines, volatile organic compound (VOC) emissions varied widely. The Texas Natural Resource Conservation Commission (TNRCC) requires abatement of the blowing agent. If the abatement device was not designed for the wide variation in VOCs, the abatement device could shut down under high temperature conditions. With the abatement device shutdown, the manufacturing operation must also be shut down. Two methods were used in the past to address the widely varied operating conditions. One was to operate an abatement device with a less thermally efficient recuperative style oxidizer. These units had thermal efficiencies in the range of 50 to 70%. The second method of dealing with the different operating conditions was to oversize the abatement device for the maximum VOC concentration. In this case a very large regenerative thermal oxidizer (RTO) was used to minimize operating costs. This paper will provide case history information on an innovative way to deal with effective operation in dealing withmore »« less

VOC compliance on the ball: Aluminum can manufacturer rolls to California VOC compliance

Journal Article Gay, R - Environmental Solutions

Since entering the North American beverage can market in 1969, Ball Corp., has increased its market share at a pace more than double the growth of the market itself. In addition to holding numerous patented advancements in can-making technology, Ball prides itself as an environmentally responsible company. When Ball decided to increase production capacity in its Fairfield, California, plant, the challenge was to produce more cans, while still complying with the state`s stringent air emissions regulations. As with other aluminum can manufacturing facilities, Ball`s coating and curing operations generate volatile organic compounds (VOCs). Ball`s permit from the state of Californiamore »« less
Advanced regenerative thermal oxidation (RTO) technology for air toxics control - selected case histories

Conference Seiwert, Jr, J

Advanced design regenerative thermal oxidation (RTO) systems have been developed and are in commercial scale use for control of process emissions containing air toxics (HAPs) and VOCs. High operating temperatures coupled with high thermal energy recovery efficiencies inherent with RTO technology provide for high destruction efficiencies while minimizing formation of objectionable combustion byproducts. These results are achieved with low system operating costs. This paper covers development of advanced design commercial RTO systems for control of air emissions from several important commercial processes: total reduced sulfur (TRS) and other HAPs/VOC emissions from pulp mill processes. Chlorinated organics and other HAPs/VOC emissionsmore »« less
Advantages of twin bed regenerative thermal oxidation (RTO) technology for VOC emission reduction

Conference Waldern, P; Nutcher, P; Lewandowski, D

Regenerative Thermal Oxidation (RTO) Technology is the fastest growing segment of the air pollution control equipment supply market. These normally treat waste gas streams with low concentrations of Volatile Organic Compounds (VOC). They are the technology of choice for very large volume waste gas streams because of their ability to achieve heat recovery efficiencies at high as 95%. RTO technology emerged in the mid 1980`s. Until recently, RTO designs incorporated at least three beds packed with a heat transfer medium. However, many suppliers are now offering two bed designs. Two bed designs offer significant savings in capital costs with onlymore »« less
RTOs favored to bat in cleanup position

Journal Article McIlvaine, R - Environmental Solutions; (United States)

In the volatile organic compound treatment industry, the regenerative thermal oxidizer is the cleanup hitter. In comparison to recent modest growth in the catalytic and recuperative thermal gas treatment segments, growth in RTO sales has been spectacular. An RTO uses a series of packed ceramic beds operated in a cyclical fashion to store the heat generated by VOC combustion. Heat recovery is achieved by redirecting the gas flow periodically so incoming process gas flows through a media-filled vessel that has been heated by contact with the fully combusted gas. Once the incoming gas has been pre-heated by contact with themore »« less
RTO heat recovery system decreases production costs and provides payback

Conference Lundquist, P

Application of a heat recovery system to an existing regenerative thermal oxidizer (RTO) was considered, tested, and selected for decreasing production costs at a pressure sensitive tape manufacturing facility. Heat recovery systems on RTO's are less common than those on other thermal oxidizers (e.g., recuperative) because RTO's, by the nature of the technology, usually provide high thermal efficiencies (without the application of external heat recovery systems). In this case, the production processes were integrated with the emission controls by applying an external heat recovery system and by optimizing the design and operation of the existing drying and cure ovens, RTOmore »« less
