Contract Research and Development

Since the 1970's, ETS has conducted contract research and development for both industry and government. This work has included bench and pilot studies on control equipment, and field studies on test methodologies.

Partial List of Contract Research
Listed below are examples of contract research studies conducted by ETS. Included are studies of long-term monitoring of utility boiler baghouse operation and maintenance, as well as cost-reduction assessments; development of methods to measure emissions; and ambient air studies.

• Test Method Development - Lab
  Methods development for halogen emission measurement.
• Fabric Evaluation - Lab
  Filter fabric evaluations of fabrics under development (e.g., PTFE, glass blends, felted glass, pleated filters).
• Ambient Study - Field
  Long-term multi-station ambient concentration study of polycyclic organic compounds.
• Filter Bag Study - Lab
  Filter bag performance evaluation.
• Mercury Assessment - Paper
  Mercury emission data analysis and assessment. 
• Bag Performance - Lab
  Long-term bag performance monitoring.
• Process Study - Lab

Partial List of Pilot Plant Programs
Below is a partial listing of pilot studies conducted by ETS. In most cases these projects included the design, fabrication, installation, start-up, and long-term operation of the pilot plant. These efforts typically included the screening of design options, test program design, determination of operational procedures, performance evaluations, and economic evaluations.
