Project Summaries for Manufacturing Facilities


Client: Computer System Manufacturer – Emission Source: Scrubbers,

Carbon Adsorbers, and Dust Collector

AirNova, Inc. conducted two (2) evaluation programs to determine the emission rates of air toxics from eight (8) scrubber systems, six (6) carbon adsorption systems and one (1) dust collector. Emission measurement parameters included arsenic, phosphorus, boron, nitric acid, sulfuric acid, hydrogen chloride, hydrogen fluoride, ammonium hydroxide, potassium hydroxide, butyl acetates, isopropyl alcohol, acetone, CFC-113, and perchloroethylene.


Client: Metal Plating Facility – Emission Source: Plating and Degreasing Operations

AirNova, Inc. has conducted several air toxic emission test programs to determine the emission rates of the following parameters: CFC-113, nitric acid, hydrogen chloride, hydrogen fluoride, sodium hydroxide, boric acid, potassium iodide, cyanide, and acetic acid from five (5) emission sources. The maximum allowable stack concentrations for each of the air toxics were determined utilizing procedures from the State of Connecticut’s Air Pollution Rules.


Client: Glass Manufacturing Facility – Emission Source: Fossil Fuel Fired, Oxyfuel and Electric Boost Glass Furnaces

Emission evaluation and compliance test programs were conducted for twelve (12) glass furnaces in operation at a single facility. Sampling was conducted in determination of particulate matter, sulfur oxides, total hydrocarbons, nitrogen oxides and carbon monoxide utilizing EPA Reference Methods 5, 8, 7E, 10 and 25A. Particle sizing determinations were also conducted for several sources.


Client: Polyvinyl Chloride Manufacturer – Emission Source: Reactors, Mixers, and Extruders

A facility wide emission inventory was conducted at this site and involved the determination of specific emissions associated with seven stationary sources. Sampling was conducted in determination of particulate, PM-10, sulfur oxides, hydrogen chloride, chlorine, multiple metals and vinyl chloride utilizing EPA Reference Methods in addition to State specific procedures.


Client: Fiberglass Manufacturer – Emission Source: Glass Furnace, Oven Exhaust, and Forming Line

A control system evaluation program was conducted at a facility which involved the determination of simultaneous emissions at seven (7) separate locations. Emissions of particulates, condensable particulates, phenol, ammonia, formaldehyde and non-methane hydrocarbons were determined simultaneously and in triplicate at seven (7) test locations during four (4) separate operating conditions.


Client: Polyvinyl Chloride Film Manufacturer – Emission Source: Reactors and Mixers

An emission compliance test program was conducted at a facility in determination of emissions from five (5) sources. Sampling was conducted in determination of emissions of particulate, non-methane hydrocarbons and specific volatile organic compounds. EPA Methods 1, 2, 3, 4 and 5 as well as Compendium Methods T0-12 and T0-14 were utilized for this project. A total of twenty-eight (28) test runs were performed. Three dimensional (3-D) pitot traverses were also conducted.
