Air Pollution Control Laboratory

Locations: 717 Rhodes Hall; 469 ERC
Director: Dr. Tim C. Keener
office: 472 ERC

The Air Pollution Control Laboratories are designed to allow for the study of controlling air pollutants from industrial and natural sources. The laboratories have facilities for both bench and small pilot scale experiments. Analytical equipment includes gas analyzers for the continuous measurement of oxygen, carbon dioxide, oxides of nitrogen, sulfur dioxide, ammonia, ozone, total hydrocarbon emissions and carbon monoxide. Cold vapor atomic absorption method is available for the determination of mercury. In addition, methods have been developed using GC-MS for the determination of specific hydrocarbon emissions such as chlorinated hydrocarbons and polycyclic aromatic hydrocarbons (PAHs). Solids characterization equipment includes instrumentation available for the determination of physical properties of solids such as specific surface area (BET method), true density, particle size and morphology. Fuel and solids elemental composition analysis is available via a total carbon and sulfur analyzer and a thermogravimetric analyzer is available for the determination of weight loss of solids as a function of temperature.

These laboratory facilities are typically used to support funded research activities. Currently, a variety of experimental investigations are underway. A pilot scale entrained flow reactor has been developed and is operational for the study of gas-solid reactions for the control of acid gases and heavy metals from combustion flue gases. This reactor has the capability of continuously injecting solids into a simulated flue gas for the determination of reactivity in the entrained flow mode, or in the packed bed mode across a fabric filter. The entrained flow mode can be maintained under isothermal conditions from 20 - 1200 oC (70 - 2192 oF) for residence times from 0 - 1.5 seconds. The unit has a fabric filter simulator which can operate from temperatures of 20 - 200 oC (70 - 400 oF) with a filtration velocity of from 0.15 - 3 m/min (0.5 - 10 ft/min).
