The B&W MEGTEC EII-150 Regenerative Thermal Oxidizer (RTO) is a system designed for the destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) in industrial exhaust airstreams.
Here's a breakdown of its features and how it operates:
How it works
Regenerative Thermal Oxidation: The EII-150 utilizes regenerative heat exchange, where ceramic media beds preheat the incoming contaminated air and capture heat from the exiting clean air, significantly improving fuel efficiency and reducing operational costs.
Oxidation Chamber: Polluted air, preheated by the ceramic media, enters a combustion chamber operating at high temperatures (typically 1500°F/815°C or higher) where the VOCs and HAPs are oxidized into harmless byproducts like carbon dioxide and water vapor.
Heat Recovery: Clean, hot air then passes through a second ceramic media bed, transferring its heat to the media for use in preheating the next incoming polluted airstream.
Poppet Valves: The EII-150 uses a system of poppet valves that direct the airflow through the ceramic media beds, alternating the direction every few minutes to maximize heat recovery and destruction efficiency.
Key features and advantages
High VOC destruction: Can achieve up to 98% VOC destruction, with options available for even higher destruction rates.
High thermal efficiency: Achieves thermal efficiencies up to 97%, meaning it requires minimal additional fuel to maintain the oxidation temperature, even at relatively low VOC concentrations.
Cost-effectiveness: Offers low operating costs due to its high thermal efficiency and reduced fuel consumption.
Operational reliability: Designed for reliable operation, featuring durable poppet valves and an advanced electronic control system that automates operation, minimizing operator interaction according to Environmental XPRT.
Compact design: The EII-150, also known as Millennium®, features a unique, single-box configuration, reducing its footprint and allowing for flexible installation, including rooftop placement.
Fast installation: Pre-assembled, pre-wired, pre-piped, and pre-tested at the factory for quick installation and startup.
Applications
Regenerative thermal oxidizers, like the EII-150, are used in a variety of industries that generate VOC and HAP emissions, including:
Automotive Manufacturing
Chemical Processing
Coating & Converting
Printing & Packaging
Pharmaceutical & Medical Devices
Food & Beverage Processing
And many others.
In essence, the B&W MEGTEC EII-150 is a reliable and efficient solution for addressing air pollution control needs in diverse industrial applications.
