Project Summaries for Waste Gas Oxidation Facilities

Client: Waste Treatment Facility – Emission Source: Oxidation and Settling Tank Scrubbers

AirNova, Inc. determined the removal efficiency of an air toxics scrubber system. Target compounds included benzene, carbon tetrachloride, chloroform, dioxane, ethylenimine, ethylene dibromide, ethylene dichloride, 1,1,2,2 tetrachloroethane, tetrachloroethylene, 1,1,2-trichloroethane, trichloroethylene and total hydrocarbons. The testing was conducted on two (2) permanganate scrubbers which serve as the pollution control devices for oxygenenation tanks and settling tanks associated with a waste treatment plant.


Client: Regional Sewage Authority – Emission Source: Regenerative Thermal Oxidizer

AirNova, Inc. conducted an emission compliance test program on a Regenerative Thermal Oxidizer serving as the pollution control device for exhaust gases from a sludge handling facility. Inlet and outlet sampling was conducted for ammonia, hydrogen sulfide and carbon monoxide as well as other specific air toxics.


Client: Landfill Remediation Site – Emission Source: Landfill Gas Flare

AirNova, Inc. conducted an annual emission compliance test program on a landfill gas flare. The test program involved the measurement of VOC air toxics, total organic halides, total hydrocarbons, methane, sulfur dioxide, oxygen/carbon dioxide as well as the higher heat value and specific gravity of the landfill gases.

Client: Soil Gas Remediation Facility – Emission Source: Thermal Oxidizer

AirNova, Inc. conducted two emission compliance tests on a thermal oxidizer serving as the pollution control device for a soil gas extraction system located in New Jersey. Emission sampling was conducted for VOC air toxics, total hydrocarbons and carbon monoxide.


Client: Regional Sewage Authority – Emission Source: Internal Combustion Engines

AirNova, Inc. conducted an emission test program at the outlet of three (3) internal combustion engines for NOx , CO and NMHC. Testing was performed while the engines were operated at various loads and timing settings. The engines were fired with both 100% natural gas and a mixture of natural gas and digester gas. The collected emission data aided the development of a NOx control strategy and was used to complete operating permit applications.


Client: Municipal Landfill – Emission Source: Landfill Gas Fired Engine / Generator Sets

An emission compliance test program was conducted for two (2) internal combustion engine/generator sets fired with extracted landfill gas. Sampling was conducted at the engine outlets in determination of non-methane hydrocarbons, nitrogen oxides, carbon monoxide and hydrogen sulfides. Total non-methane hydrocarbon concentrations and mass flow rates were determined simultaneously at the feed gas inlet to each engine with outlet sampling events.
