According to recent scientific studies, EtO is a more dangerous carcinogen than previously thought. Results from the latest National Air Toxics Assessment (NATA) have made EtO an increased focus of concern for the EPA, state regulators and worldwide regulatory authorities.
This understandably makes sterilization companies concerned about the safety of employees and the community. In a number of instances, the traditional abatement technologies cannot meet the new EtO destruction requirements.
In the United States, the selected air pollution control device must be in compliance with NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations that dictate more than 99% destruction efficiency of EtO (Ethylene Oxide), or concentration levels which are less than one part-per-million by volume.
Keeping Industrial Coaters Profitable with Rebates and Efficiency
The Challenge
In the Midwest, a family-owned metal wall and roofing manufacturer was looking to grow their production capabilities whilst benefiting from local utility rebate programs.
Their existing operation was made up of three painting booths venting directly to the atmosphere. They planned to install two new paint booths as a part of the expansion, and pollution abatement equipment would have to be installed to accomplish this.
Their application brought about the below design challenges for the emission control solution required:
Space was a huge concern, as the equipment had to fit in a tight space.
Service and Maintenance Strategies for Environmental Compliance
While the current global pandemic sees many manufacturers having to factor in the unknown, pollution control equipment still needs to be considered as part of a business’s decision making process.

When facing uncertainty and rapid change, a calculated investment in existing pollution control systems can ensure compliance as well as offering opportunities for a quick return on investment (ROI).
These needs can include the addition of new process lines for new or expanded product offerings, changes in input process, increasing the speed of process lines, the consolidation of production plants, or the building of new facilities. Anguil is at hand to evaluate current equipment, capacities and production requirements to create a strategy that will fit the emerging needs of any business.
Advances in Paint Fume, Emission Control Techniques and Technology
The Regenerative thermal oxidizer (RTO) is currently the leading technology employed in the capture and destruction of pollutants due to the low concentrations of emissions coming from paint booths.
While RTOs are extremely effective, they are dependent on a continuous flow of emissions from the process to power the combustion of the incoming contaminants.
By employing a concentrator, exhaust streams at or near ambient temperatures can be concentrated to a point where the airflow delivered to the oxidizer can be decreased by a factor of between 8 to 20.
Not only is this greatly reduced flow generally rich in emissions, but it will also result in greater cost-efficiency when it comes to operating the oxidizer system.
Individuals, small companies and large corporations are all aiming to reduce their carbon footprints. As a result, the use of Lithium-Ion Batteries (LIB) has become progressively more widespread.
Where individuals are concerned, the utilization of battery packs in sectors such as solar-powered homes and all-electric automobile battery banks has been expanding at a rapid pace.
The manufacture of such battery packs generates a number of air contaminants that need to be treated preceding release into the atmosphere, however.
A major supplier of LIBs was confronted with a distinct array of challenges at its central production facility.
Three identical abatement systems were required, with each one needing the capacity to handle upwards of 35,000 scfm of emission-laden air, which is larger than the typical size of an electrically heated air pollution control system. The systems needed to factor in the following considerations:
