MSW Air Pollution Control

 

Electric Utility Bag Life Guarantee

Client      Leading Manufacturer of Air Pollution Control Systems
Description      
ETS was retained by a leading manufacturer of air pollution control systems to determine the technical reason for filter bags not achieving the multi-year bag life guarantee.  ETS was able to determine that the baghouse was operated outside the guarantee's operational parameter range.  This, in addition to other ETS O&M findings, allowed the client to win this case.


MSW Incinerator Emission Control Performance

Client      Large MSW Incineration Plant
Description      
ETS was retained to evaluate problems with a large MSW incineration plant's emission control system.  The initial step was a site visitation to determine original equipment design and current operation performance.  A report was issued documenting the existing problems and establishing an evaluation plan to confirm the cause of the problems and define solutions.  An ETS troubleshooting team subsequently implemented the plan and verified the source of the problems using ETS's own patented baghouse performance instrumentation.  A modified mode of operation was suggested to temporarily relieve existing problems (including intermittent emissions), and long-term solutions were recommended.  ETS was requested to determine if the unit met the original specifications of the manufacturer, and the cost impacts of any necessary changes.  The plant elected to enter legal arbitration with the original equipment vendor, and ETS supplied expert testimony during the litigation process.


Steel Manufacturer - Electric Arc Furnace / Baghouse

 

Client      Major Steel Manufacturer
Description       
ETS was retained as as expert witness by a major steel manufacturer for problem assessment and testimony.  The client was operating a pulse jet baghouse for control of particulate emissions from an electric arc furnace.  The system was designed to handle 100,000 ACFM, but due to excessive pressure drop could handle no more than 80,000 ACFM.  ETS researched this problem including conducting a detailed data inspection and review, an engineering evaluation with economic analyses, and issuance of a report discussing the problem assessment and solutions to the problem.


Comprehensive Air Pollution Control System Capability Assessment


Description       
ETS was retained to provide technical back-up and rebuttal testimony, and to develop exhibits for the proposed air pollution control hardware at a large MSW installation.  The overall objective of this case was to thoroughly investigate state-of-the-art APC technology for MSW incineration, along with associated economics and regulation in other states, to "determine a reasonable and rationally consistent set of minimum emission standards and monitoring requirements for these types of facilities."  The Department of Environmental Regulation was seeking reasonable assurance that the operation of such MSW systems would not cause more air environmental problems than the solid waste problems they were attempting to solve.  ETS supplied expert consulting and testimony for the case.  The client was very pleased with this service, which led to an increase in this activity at ETS.


MSW Air Pollution Control

Client      MSW Incinerator Operator
Description       
ETS was retained by an MSW incinerator operator to provide expert testimony for litigation between the operator and the air pollution control equipment vendor.  An ETS principal provided expert testimony on several occasions, which focused mainly on the areas of system design volumes and temperatures; the reasonableness of existing baghouse inlet temperature; individual component and total system pressure drops; vendor's standard bag attachment design; and surge condition limitations and bag life.
