AirSource Technologies, Inc. was retained by a major national portland cement manufacturing company to perform RCRA Trial Burn and Comprehensive Performance Test Programs for their multiple kilns firing hazardous waste fuels.
Some fifteen separate test programs have been conducted over a ten year period, typically entailing sampling to determine Destruction Removal Efficiency of principal organic hazardous constituents (POHCs), and measurement of emissions of dioxin/furan compounds, multi-metals, HCl, particulate, VOST, semi-volatiles, and the common CEM priority pollutant constituents.
AirSource normally mobilizes a crew of up to 20 personnel to conduct these trial burns often working on an around-the-clock basis to minimize the duration of interruption to normal plant production.
Under contract with a major international chemical manufacturing firm, AirSource was retained to:
AirSource Technologies, Inc. was retained to conduct inlet/outlet testing of two wet scrubbers treating emissions from a battery of hard chrome plating circuits. Employing Method 306 to optimize test precision for determining total chromium, our crew completed the testing expeditiously despite contending with subzero temperatures & heavy snows from a major winter storm.
EMISSION INVESTIGATION STUDY
Our client requested a study to determine the makeup and quantity of emissions from a variety of plant production sources. Testing included total particulate, PM10, total hydrocarbons, and speciation of potential Hazardous Air Pollutants (HAPs) by on-site extractive FTIR. Certain sources were also sampled and analyzed for volatile and semi-volatile organics. Eight separate sources were evaluated during the investigative study, which provided process data necessary to properly design the client’s air pollution control systems.
RESEARCH INVESTIGATION AND COMPLIANCE TESTING
Working with a consultant to a consortium of charcoal production companies, AirSource Technologies, Inc. provided technical direction and field-testing services at a variety of locations.
This study focused on potential emissions from varying types of charcoal kilns and briquetting facilities and involved simultaneous monitoring of VOCs, particulate (PM10), and priority pollutant gases (CO, NOx).
AirSource led negotiations with EPA to develop test methodologies for this difficult sample matrix. EPA technical staff observed the testing and accepted the test results in full.
INVESTIGATIVE AND COMPLIANCE TESTING OF GAS TURBINE RETROFIT
Employing Method 20, AirSource Technologies, Inc. performed NOx testing for a newly constructed power generating facility at a Midwestern municipality. Twin gas turbines, converted from commercial aviation applications, drive a common generator. Using special twenty-foot probes, the respective stacks from the turbines were tested individually, both initially for assessing operational performance and, again for compliance demonstration purposes.
FACILITY WIDE VISIBLE EMISSION EVALUATION AND NSPS PERFORMANCE TEST PROGRAM
In support of a Title V submittal project, AirSource Technologies, Inc. conducted a facility-wide evaluation of a major limestone and portland cement production facility. Extensive photo-documentation and Performance Testing verification was conducted in conjunction with this program.
AirSource Technologies, Inc. was contracted to perform a range of test measurements for a leading aluminum casting firm operating melting furnaces in the Midwest. In addition to an evaluation of emissions for multiple metals, AirSource personnel monitored for particulate, and common priority pollutants.
MACT COMPLIANCE DEMONSTRATION TESTING
AirSource Technologies, Inc. was contracted to perform a range of test measurements required by the promulgation of the Secondary Aluminum MACT standards, on behalf of a firm specializing in smelting and casting of recycled aluminum for manufacture of automotive parts. Testing included measurements of Hazardous Air Pollutants for establishing Area vs. Major Source Determinations, as well as dioxin/furan compounds associated with chlorine emissions from fluxing operations.
ROD MILL AND COOLING PEN EVALUATION
Working on behalf of a scrap steel recovery, remelting and product fabrication firm, AirSource Technologies, Inc. conducted particulate testing and continuous emission monitoring of a rod mill exhaust stack. In addition, testing was performed to determine NOX emissions associated with a slow cooling pen associated with ball mill production.
OVERALL APC SYSTEM FLOW STUDY
For this same firm, AirSource conducted an APC system flow study. This study entailed simultaneous flow traversing and data recording associated with a network of massive main ducts, most requiring twenty-foot probes for test purposes. Interpolation of resultant data provided system redesign criteria, which ultimately resulted in substantial improvement in system performance.
HOSPITAL WASTE INCINERATOR
The disposal and incineration of hospital infectious and other waste is carefully regulated. AirSource Technologies, Inc. has worked with a large Midwestern hospital providing comprehensive services to demonstrate ongoing compliance with city/county air regulations. These annual tests routinely involve testing for metals, particulate, HCl, dioxins/furans, and typical continuous emission monitoring constituents.
On behalf of our client AirSource appealed to the regulatory agency to reduce these costly test burdens and were successful.
RECOVERY SYSTEM/AFTERBURNER VOC SPECIATION
In order to demonstrate compliance control of a VOC recovery/afterburner installation, AirSource conducted on-site GC speciation of VOC constituents by Method 18 collecting samples continuously around-the-clock in large vacuum canisters. Samples were then analyzed "Real Time" by field chromatographers.
STEAM POWER PLANT AIR LEAKAGE STUDY
In order to evaluate overall plant and control system performance, this utility retained AirSource Technologies, Inc. to conduct detailed measurements of volumetric flow, oxygen, and carbon dioxide levels in huge main ducts in the Economizer Outlet, Air Heater Inlet, and Exhaust Stack locations.
Using twenty-foot sampling probes equipped with CEM sample connections and Pitot measurement lines, the AirSource crew traversed these ducts and stacks, while continuously recording the determined concentrations of each parameter.
NSPS NEW FACILITY COMPLIANCE DEMONSTRATION
Following construction of one of the largest automobile battery manufacturing facilities in the nation, AirSource was retained to provide compliance test services specifically targeting lead emissions. Working from a very strict protocol requiring extensive blank train evaluations due to a history of contamination problems inherent with battery plant testing, AirSource tested some twelve different process sources with all runs "passing" and with no detectable background contamination.
VOC ABATEMENT SYSTEM COMPLIANCE DEMONSTRATION
AirSource was retained to conduct a system-wide simultaneous evaluation of VOC emissions and Destruction and Removal Efficiency of a Thermal Oxidizer. Using five FID detectors, we measured two process inlet streams entering a dual carbon concentrator system. We then measured two concentrator outlet locations feeding a Regenerative Thermal Oxidizer (RTO), and the stack exit from the RTO.
The precision and repeatability of the test runs allowed our client to file a permit modification changing this facility from an Intermediate Source to a Deminimus Source with substantial cost savings and elimination of much of their regulatory reporting requirements.
LIME KILN EXHAUST EMISSION INVESTIGATIVE STUDY
AirSource was retained by one of the country’s leading lime producers to assist them in evaluating the effects of kiln/scrubber operating conditions on particulate and gaseous emissions.
A systematic test plan was developed wherein our client made specified adjustments to kiln and scrubber operating parameters while corresponding testing was taking place. Using proprietary techniques, AirSource provided "real-time" particulate results. We then integrated test data with process data to develop meaningful correlative information.
SEWAGE SLUDGE INCINERATOR PERFORMANCE TEST
AirSource provided Incinerator Performance Testing Services and Relative Accuracy Testing of a Continuous Emission Monitoring system associated with the incinerator.
Testing successfully demonstrated the facility’s compliance with current State and Federal regulations for sludge incineration.
PERFORMANCE OF INVESTIGATIVE EMISSION TESTING
AirSource has worked with several respected firms specializing in
environmental law, typically providing investigative emission measurement
services wherein the subject industry has an interest in maintaining
confidentiality (through Attorney/Client Privilege) of the test results.
