Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation
A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points. These would include explosive compounds present in the vapor stream. The portable TU-51VPVOC (OEM) operates the following process: vapors are recovered from geologic units via SVE, often from a ...

Total Enclosures Capture 100% of a Facility`s Air Pollution
Over the past decade the use of total enclosures to demonstrate and/or maintain capture of printing press emissions has become very popular within both the flexographic and rotogravure printing industries. Operating a printing press within a properly designed and approved total enclosure assures virtually 100% capture of the volatile organic compounds (VOCs) and/or hazardous air pollutants ...

What is the Difference Between a Regenerative Thermal Oxidizer and a Recuperative Thermal Oxidizer?
While both are a type of Thermal Oxidizer, the difference between a Regenerative Thermal Oxidizer (RTO) and Recuperative Thermal Oxidizer is how these machines recover heat during the oxidation process. Each technology destroys pollutants by heating the dirty airstream to very high temperatures to destroy the hydrocarbons (VOC) in the airstream. Each utilizes heat recovery to reduce the gas use ...

Case study - Converter finds affordable compliance solution
Overview It’s not just about increasing production for Fredman Bag’s president, Tim Fredman Jr., it’s also about being a environmentally conscious neighbor. A converter’s decision to expand their capacity is often made more complicated by a corresponding need to invest in air pollution control equipment. Recent expansions had Fredman Bag making major investments in their ...

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 ...

Case study - New or used? Business expansion introduces many difficult decisions
When you run a family-owned business, success comes with hard work and some difficult decisions. Vince Kuber was recently faced with such a decision after taking over as President and CEO of Prestige-Pak, a Wisconsin-based Flexographic printing company. His parents started the business over thirty years ago and it wasn’t long after Vince took over that the decision to expand needed to be ...

Air Pollution Control in the Printing and Web Coating Industries
For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new. In these industries, depending upon their location, companies have been installing APCS since the early 1970's. However, for some companies the clock is still ticking regarding their compliance with local, state and federal clean air ...
