Overview
Aerosol mist collectors - specifically, fiber bed filters (FBF) - are used to control visible (opacity) emissions caused by submicron aerosol emissions. Industrial applications are many, from asphalt emissions control to plastic calendaring. Because they perform efficiently over a large range of operating parameters, FBF selection involves a number of tradeoffs. For example, if a system can be designed with a bed velocity range of 10-40 ft/min, and still meet the opacity requirement, why not go with 40 ft/min and get the lowest capital cost? This presentation explains the consequences of making that selection at the expense of other crucial design parameters. Understanding the relationship between the design parameters will help attendees make the informed decisions needed to meet project objectives - without creating an operational road block or a system with operating cost that can quickly consume any capital cost savings.
Key Takeaways
- Understand how fiber bed filters (FBF) are used to control aerosol emissions, either as a standalone device or as a 'pre-filter' for other air pollution control (APC) devices
- Learn how key design elements - such as bed depth, fiber size, bed density, and flow direction - affect system performance
- Work with a fixed design parameter and discover the potential differences in final equipment design
- Learn how to balance the 'tradeoffs' between capital costs and operating costs
