Thermal Oxidizer Capture Efficiency - Photographic Equipment Manufacturer

APCC worked with a major manufacturer of photographic equipment and films to help bring a regenerative VOC thermal oxidizer serving seven coating lines into compliance with a bubble permit. The permit required 100 percent capture and 95 percent control efficiencies for VOC emissions. Prior to attempting compliance testing, APCC performed diagnostic testing and specified repairs for the oxidizer system that was performing far below specifications.

Initially, the local regulatory agency would not accept US EPA guidance for determining capture efficiency. Therefore, APCC proposed using the liquid/gas method for demonstrating capture efficiency. Precise measurements of applied coating material were performed concurrently with emission measurements using EPA Method 18. Eleven (11) different solvent species were characterized simultaneously, using on-line gas chromatography with flame ionization detectors.

After discussions with the local agency during which APCC presented the data obtained from the capture demonstration, the agency agreed to accept EPA’s PTE (permanent total enclosure) protocol for determining capture efficiency, but would only assume 99 percent capture efficiency, not 100 percent and added the caveat that 97 percent destruction efficiency be demonstrated for the thermal oxidizer. Following engineering modifications and additional diagnostic testing, a compliance test program successfully demonstrated compliance with the new permit requirements.

 
Air Pollution Control Strategy - Web Offset Printer

APCC developed an air pollution control strategy for VOC and printing oils for a major web offset printer. The major obstacles were the varying phases and the nature of printing oils, which vary significantly from batch-to-batch and tend to volatilize and crack at the elevated temperatures in the curing ovens. Test programs included on-site gas chromatographic analyses of effluent to determine emission rates of specific compounds and to quantify the volatile fraction of the printing oils.

A study was performed to determine air pollution control strategies to satisfy different printing lines located in four states, each with different emission definitions ranging from VOC to particulate to condensable organic compounds. APCC worked with the client to develop bid specifications and conduct performance testing on the chosen controls (condensers, incinerator and carbon absorption) and required CEMS. All facilities have since successfully demonstrated compliance with state permits and consent agreements.


CEMS Installation and Performance Specification Testing

APCC was retained by three separate printing and coating companies to install a CEMS for CO and O2 on thermal and catalytic oxidizers, and perform CEMS Performance Specification Tests, as required by the State Air Pollution Control Regulations. The tests were conducted to determine relative accuracy and precision according to Federal performance specifications with success. All systems met 40 CFR 60 Appendix B Performance Specifications and are now successfully operating.


Emission and Control Efficiency Testing - Catalytic Fume Incinerator

APCC was retained to conduct capture and control efficiency testing on a catalytic fume incinerator controlling emissions from four tenter frames, one fabric coating line, and one loop dryer by a textile manufacturer of coated fabrics. The testing was conducted in response to an Administrative Order requiring control of odor emissions from the source. The test program performed was based on requirements in the temporary Certificate to Operate Control Apparatus or Equipment (Conditional) and Conditions for Permit to Construct and Certificate to Operate.

Sampling and analyses were performed at the inlet and outlet of the catalytic fume incinerator and a number of roof units in accordance with state DEP Method and EPA Methods 1, 2, 18, and 25A determining emission rates, destruction and capture efficiencies of Volatile Organic Substances (VOS), as total hydrocarbons and by individual species. Capture efficiency using a "Building as Enclosure" scheme with eight exhausts was also determined. CO, CO2, and O2 were measured at the exhaust stack as a measure of combustion efficiency. All six lines were operated during the test program, representing worst case conditions, with total finishing/coating usage approximately 1127 lbs/hr.
