Catalytic products international replaces RTO with a VECTOR Catalytic Oxidizer - Case study
A chemical processing facility recently installed a VECTOR Catalytic Oxidizer to replace a competitors Regenerative Thermal Oxidizer. The RTO was installed 5 years earlier and could not provide the reliability demanded by the client. The problem stemmed from a basic mis-application of the technology. As is very common, many air pollution control equipment manufactures have abandoned recuperative ...

The Role of Carbon Dioxide Detection in the Prevention of Sick Building Syndrome
Sick building syndrome (SBS) is a medical condition where people, who work or live in the same building, suffer a variety of symptoms of illness and feel unwell, for seemingly no apparent reason. Common symptoms include eye irritation, headaches and shortness of breath. Typically, all of these symptoms are alleviated as soon as the sufferer leaves the building or room in question. While the exact ...

VOC Abatement Technology Saves on Operating Costs for Aerospace Paint Finishing
For over 10 years, a Canadian aircraft manufacturer has saved over $500,000 annually in fuel and electricity consumption by using Munters rotor concentrators to control solvent emissions from its facility’s paint booths. Before purchasing Munters equipment in 2002, the manufacturer struggled with the inconvenience of having their aircraft systems flown to be painted in subcontracted paint ...

Simulating accumulation of biofilms in biotrickling filter
Accumulations and spatial and dynamic variations of biofilms in the media of a biotrickling filter were simulated using mathematical models for Volatile Organic Compound (VOC) removal. Toluene was selected as the model VOC. Effects of toluene concentration and gas Empty Bed Contact Time (EBCT) on VOC removal were also investigated. Results showed that biofilm thickness increased with increased ...

Air Emissions/Off-Gas Treatment
A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

Controlling Pharmaceutical Coating & Drying Process Emissions
Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...
