MLM® vs. Conventional RTO Heat Recovery Media
Random media, in addition to high pressure drop, are also associated with common operational problems when used as the heat recovery media in RTO units. These problems include settling and nesting which leads to even higher pressure drop (and hence higher operating expenses), as well as degradation over time.

Paint and Coatings VOC Emission Control - Case Study
Colt Technologies designed and installed two MAXIM Regenerative Thermal Oxidizers (RTOs) at a new railcar manufacturing facility. Each RTO controls Volatile Organic Compounds (VOC) and paint spray booth emissions from 40,000 scfm of exhaust air from paint spray booths and interior lining operations at the plant. The RTO systems reduce VOC emissions by 98% utilizing custom ceramic heat transfer ...

Case study -New media makes RTO natural gas usage a rarity!
Overview Tekra Corporation has always had an eye on their energy conservation. They are a custom coater of plastic films in Wisconsin where state regulations require over 98% of the Volatile Organic Compounds (VOCs) emitted from their process be destroyed in an oxidizer system. While considering their first oxidizer system, Tekra's Engineers did their homework and invested in an early model ...

Wet electrostatic precipitators: A preferred technology for emission control
The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

Metal Coating Emission Control
As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking plant in the Midwest had been using a thermal recuperative oxidizer with direct heat recovery for control of emissions from its sheet coating lines. ...

Case study - Engine test cell exhaust: RTO
Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal of water vapor and ...

Case study - Increasing oxidizer capacity by 80,000 SCFM
Overview A recreational products company bought a three year-old manufacturing facility with an existing regenerative thermal oxidizer (RTO) for the production of their outboard engine. They required emission control equipment to manage the volatile organic compounds (VOCs) emitted by the solvents used in the engine painting processes. The company wanted to minimize overall costs by using the ...

Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study
Example: Aluminium recycling Similar tasks: Recycling of copper, lead, cink The waste gas in metal recycling usually contains particles (abraded metal, mineral dust), inorganic, acid substances (HF, HCI, SOx) and dioxins (PCDD/F) as well as a whole range of organic substances (unburned hydrocarbons) and carbon monoxide. Particularly, in the group of unburned hydrocarbons some substances such as ...

Case study - Printing: RTO solution
Overview A flexographic converter needed to expand its business by adding an 8-color CI printing press to its existing press lines, and planned to add a second press later. The increase in emissions and flow from the new press was beyond the capacity of the existing 10-year old catalytic oxidizer. The customer needed a way to maintain compliance at an affordable cost. Action After a thorough ...

Regenerative Thermal Oxidizers…What You Should Know.
Within industry today, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new. In response to Congressional guidelines passed in the 1970’s, a number of companies with VOC emissions have been operating air pollution control systems of one type or another for 25 years or more. These guidelines have been revised and added to as the years progressed, making ...
