A renewable natural gas facility in the southern United States will use a 12,000 scfm regenerative thermal oxidizer (RTO) to control the waste gas from its LFG purification process at a landfill. The oxidizer provides 98.5 percent destruction rate efficiency (DRE) and 92 percent thermal efficiency.
A North American plastics company needed a way to control emissions as it increased production capacity. A system, designed by Ceco Environmental, will capture and treat hazardous air pollutants (HAPs) for the company through a packaged Venturi scrubber and Adwest regenerative thermal oxidizer (RTO).
A composite and laminate manufacturer utilized a regenerative thermal oxidizer (RTO) to provide cost-effective VOC control for styrene, formaldehyde, methanol and alcohol hydrocarbons. Designed and manufactured by Ceco Environmental, the Adwest Retox is reportedly able to improve resource recovery and reuse with a proprietary heat transfer media rated at 95 percent thermal efficiency.
Regenerative thermal oxidizers (RTO) came on the scene some 35 years ago and, for the past two decades, have been the “technology of choice” for industrial VOC control. With many incremental improvements, regenerative thermal oxidizers do not risk losing this status any time soon.
Companies in all industries are constantly seeking ways to reduce a plant’s operating costs and carbon footprint. At the same time, they are looking to avoid costly utility-distribution improvements by optimizing the facility’s energy consumption.
Does it make sense to add secondary heat recovery systems to your thermal process to capture and repurpose the BTUs you have created before they escape out the top of the stack? An economic analysis can help you determine whether it is justified at your plant.
Secondary heat recovery systems capture excess energy in the exhaust stream of processes or oxidizers. On the surface, heat recovery makes good sense: Capture the waste energy and repurpose it rather than throwing it out an exhaust stack. The concept sounds relatively straightforward. As with most things, however, the proof lies in the details.
