VOC Abatement Improves Air Quality

VOC and HAP Abatement

As is the case for many industrial manufacturing processes, emissions are best destroyed through the use of thermal and catalytic oxidation technologies. Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) are destroyed through the use of high temperature combustion with direct heat recovery. The harmful air pollutants are converted to heat, water vapor and carbon dioxide, creating a destruction efficiency greater than 99%.

It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase. The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.

Waste to Energy

We can treat the air streams from waste management plants, MBT (Mechanical Biological Treatment) reception and composting areas, Waste Water Treatment Plants (WWTP), Refuse Derived Fuel (RDF) Plants, gasification of waste, syngas, torrefaction, gas engines and biogas upgrading. In waste management plants and WWTP, we remove the odors that may be causing a nuisance to neighbors, with bioreactors using Biomass to degrade odorous components and where odors are particularly intractable or VOC emissions higher, thermal oxidizers to meet prescribed emission limits and odor levels. In RDF Plants, Syngas, Gasification, Gas Engine and Biogas Upgrading applications, we employ thermal oxidizers, particulate removal and DeNOX systems, for the control of VOC, NOx, CO and particulates to prescribed emission limits.

Ethanol and Biofuels

Controlling the VOCs and CO emissions produced in the feed dryers (wet and dry milling), coupled with the particulate matter being introduced and the need for the reduction of NOx are just the start of having a successful abatement solution. The challenges of smooth pressure control that reduces dryer fluctuations and plug resistant media that lessen the frequency of bake-outs are also part of a successful abatement system and we have the solutions. Our engineered oxidation systems provide reliable performance with minimal maintenance requirements. Externally accessible valve bearings and other critical components are kept out of the corrosive moisture-laden streams extending the life of the equipment and facilitate maintenance intervals. Our simple oxidizer designs control your emissions with minimal facility intervention and allow us to provide you with reliable and dependable equipment.
