Air pollution control for the metal decorating industry
Environmental regulations for air pollution cotrol at metal decorating and packaging facilities usually address can makers, base coil coaters, or metal parts and packaging manufacturers. Metal Decorating can be classified as any process where metal is formed painted, or coated. Metal Packaging is generally considered processes involved in the production of aluminum cans, light metal containers, closures and components.
The industry has experience with compliance regulations on air quality, specifically Volatile Organic Compound (VOC) and Hazardous Air Pollutant (HAP) control. Recent changes in those regulations have increased the requirements for capture and control of these emissions from metal decorating processes like ovens and dryers. VOC and HAP abatement has historically been achieved with traditional oxidizer technologies that easily destroy 99% plus of the harmful emissions. The challenges posed by recent regulations have altered the way Anguil addresses your application, focusing on emission reduction via a capture system in conjunction with the pollution control device.
Traditionally, Thermal Recuperative Oxidizers have been used because of their ability to handle high temperature, VOC-laden oven exhaust and recover the heat to be reused in heating ovens or other process equipment. The fuel-efficient, RTO (Regenerative Thermal Oxidizer) has recently become the preferred oxidation technology but there are additional equipment offerings that can dramatically improve system performance.
- Permanent Total Enclosures (PTE) increase the overall capture and control of VOCs, we will often apply this technology for better capture efficiency at the process. This allows our customers to obtain 100% capture and very high rates of overall control.
- Concentrator Systems reduce the air volume being sent to an oxidizer and can save a significant amount of money in operating and capital equipment costs. Large volumes of VOC-laden air are absorbed into a concentrator then desorbed in a condensed, smaller volume before being sent to the oxidizer. From a new equipment standpoint, concentrators decrease the oxidizer system size, saving money on capital equipment costs and operating expenses. A concentrator could also be used to increase the capacity and efficiency of an existing oxidizer system, allowing our customers to expand production without spending a lot of money to upgrade their air pollution control equipment.
- Heat Exchangers utilize hot, treated air to preheat the incoming process air. This cuts down on the fuel needed to raise the process or oxidation temperatures, thus saving energy.
There are many different solutions that Anguil Environmental Systems can offer and has provided to meet the strict environmental regulations as well as energy reduction goals. Providing full service evaluations, focusing not only on the customer's oxidizer but the total overall system is our goal.
