INSTRUMENT CONFIGURATION AND OPERATIONS FOR GAS ANALYSIS The sampling and analysis procedures used by AIR HYGIENE during tests conform in principle with the methods outlined in the Code of Federal Regulations, Title 40, Part 60, Appendix A, Methods 3a, 6c, 7e, 10, 18, 19, 20, and 25a. The flowchart on the next page depicts the sample system used by AIR HYGIENE for analysis of oxygen (O2), carbon dioxide (CO2), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOC) tests. A heated stainless steel probe is inserted into the sample ports of the stack to extract gas measurements from the emission stream. The gas sample is continuously pulled through the probe and transported via 3/8 inch heat-traced Teflon® tubing to a stainless steel minimum-contact condenser designed to dry the sample through Teflon® tubing via a stainless steel/Teflon® diaphragm pump and into the sample manifold within the mobile laboratory. From the manifold, the sample is partitioned to the O2, CO2, SO2, CO, and NOx analyzers through glass and stainless steel rotameters that control the flow rate of the sample. The VOC sample is measured as a wet gas. The flowchart shows that the sample system is also equipped with a separate path through which a calibration gas can be delivered to the probe and back through the entire sampling system. This allows for convenient performance of system bias checks as required by the testing methods. All instruments are housed in an air-conditioned trailer which serves as a mobile laboratory. Gaseous calibration standards are provided in aluminum cylinders with the concentrations certified by the vendor. EPA Protocol No.1 is used to determine the cylinder concentrations where applicable (i.e. NOx calibration gases). All data from the continuous monitoring instruments are recorded on a Logic Beach HyperLogger™ or Intellilogger™ which retrieves calibrated electronic data from each instrument every second and reports an average of the collected data every 30 seconds and 10 seconds. The averaging time can be selected to meet the client’s needs. This data is available instantaneously for printout, analysis, viewable by actual values, or examined by a trending graphs! The number of test runs, test loads, and length of runs is based upon federal and state requirements for the facility. Typical run times associated with emission testing are as follows: Type of Test # of runs Length of runs O2 Traverse (GG) 1 run @ low load (8 – 48 points) 2 minutes per point NOx Stratification Test 1 run @ base load (12 points) 2 – 4 minutes per point Subpart GG or KKKK 3 runs @ 4 loads (30%, 50%, 75%, & 100%) 15 – 60 minutes per run RATA 9 – 12 runs @ normal load 21 minutes per run State Permit Test (gases) 3 runs @ base load 1 hour per run State Permit Test (particulates) 3 runs @ base load 2 – 4 hours per run The stack gas analysis for O2 and CO2 concentrations are performed in accordance with procedures set forth in EPA Method 3a (EPA Method 20 for O2 on combustion turbines). The O2 analyzer uses a paramagnetic cell detector. The CO2 analyzer uses an infrared detector. CO emission concentrations are quantified in accordance with procedures set forth in EPA Method 10. A continuous non-dispersive infrared (NDIR) analyzer is used for this purpose. NOx emission concentrations are measured in accordance with procedures set fort in EPA Method 7e and/or 20. A chemiluminescence analyzer is used to determine the nitrogen oxides concentration in the gas stream. Total hydrocarbons (THC), non-methane, non-ethane hydrocarbons also known as volatile organic compounds (VOC) are analyzed in accordance with procedures set forth in EPA Methods 18 & 25a. A flame ionization detector calibrated with ethane is used to determine the THC concentration in the gas stream and VOCs analyzed by GC to determine methane, ethane, and remaining VOCs per EPA Method 18 determination with gas chromatograph using FID detector.

TESTING QUALITY ASSURANCE ACTIVITIES A number of quality assurance activities are undertaken before, during, and after turbine testing projects. This section describes each of those activities. Each instrument’s response is checked and adjusted in the field prior to the collection of data via multi-point calibration. The instrument’s linearity is checked by first adjusting its zero and span responses to zero nitrogen and an upscale calibration gas in the range of the expected concentrations. The instrument response is then challenged with other calibration gases of known concentration and accepted as being linear if the response of the other calibration gases agreed within ± two percent of range of the predicted values. NO2 to NO conversion is checked via direct connect with an EPA Protocol certified concentration of NO2 in a balance of nitrogen. Conversion is verified to be above 90 percent. Instruments are both factory- tested and periodically field challenged with interference gases to verify the instruments have less than a two percent interference from CO2, SO2, CO, NO, and O2. After each test run, the analyzers are checked for zero and span drift. This allows each test run to be bracketed by calibrations and documents the precision of the data collected. The criterion for acceptable data is that the instrument drift is no more than three percent of the full-scale response. Quality assurance worksheets summarize all multipoint calibration linearity checks and the zero to span checks performed during the tests are included in the test report. The sampling systems is leak checked by demonstrating that a vacuum greater than 10 in. Hg can be held for at least one minute with a decline of less than 1 in. Hg. A leak test is conducted after the sample system is set up and before the system is dismantled. This test is conducted to ensure that ambient air does not dilute the sample. Any leakage detected prior to the tests is repaired and another leak check conducted before testing will commence. The absence of leaks in the sampling system is also verified by a sampling system bias check. The sampling system’s integrity is tested by comparing the responses of the analyzers to the responses of the calibration gases introduced via two paths. The first path is directly into the analyzers and the second path includes the complete sample system with injection at the sample probe. Any difference in the instrument responses by these two methods is attributed to sampling system bias or leakage. The criterion for acceptance is agreement within five percent of the span of the analyzer. The control gases used to calibrate the instruments are analyzed and certified by the compressed gas vendors to ± one percent accuracy for all gases. EPA Protocol No.1 is used, where applicable, to assign the concentration values traceable to the National Institute of Standards and Technology (NIST), Standard Reference Materials (SRM). The gas calibration sheets as prepared by the vendor are included in the test report.

 HOW IT WORKS Fourier Transform Infrared (FTIR) Spectroscopy is used to examine and characterize organic and inorganic materials. Data is produced in the form of a spectrum, with many bands that represent chemical bonding between two particular atoms or a group of atoms in a molecule. The spectrum is subsequently compared to a set of known reference mate-rials for identification and interpretation. As an analytic technique, FTIR has several advantages. It requires only a minute sample. It takes only minutes to conduct and it will work with most liquids or gases. Air Hygiene’s sample system incorporates a heated sample pump and conditioning system to ensure data accuracy.  COMPOUND IDENTIFICATION AND DETECTION The FTIR measures the absorption of various infrared light wavelengths by the material of interest. These infrared absorption bands identify specific molecular components and structures. Air Hygiene uses two different FTIR systems, the MKS2030 and the Max-iR both which are designed to be rugged, precise and mobile. The minimum detection limits (MDL) vary with the compound and the effluent matrix being measured. Typically, MDL’s range from 40 ppb to 10 ppm depending on the compound of interest. Recently, EPA has classified formaldehyde as a probable human carcinogen as formaldehyde exposure has been associated with reproductive effects such as menstrual disorders and pregnancy problems. As a result EPA has proposed to reduce the concentration of formaldehyde in the exhaust from new or recon-structed stationary combustion turbines to 91 parts per billion by volume or less, dry basis (ppbvd), at 15 percent oxygen (if you use means other than an oxidation catalyst emission control device). Air Hygiene uses an intensifying filter in the StarBoost FTIR for high sensitivity measurements of formaldehyde. The MDL for formaldehyde is 40 ppb.  DATA ANALYSIS The FTIR spectrometer system consists of an interferometer (MKS2030 or Max-iR), a heated sample pump (ASC10), and a computer. With an infrared data station, the computer acquires, processes, stores and retrieves spectral data. Max Acquisition, a powerful new automated, multi-component, quantitative analysis program, is used for analyzing gas phase mixtures in real time. This software also allows for custom methods and individual-ized interferent recognition to be completed on site to help improve the accuracy of the results proved. Quantitative results, concentration vs. time plots, and spectra can be dis-played and updated in real-time for continuous monitoring applications. The spectra or the interferogram is a permanent record and can be analyzed at a future time to identify and quantify additional compounds not known during the initial testing program. For example, if the sample was tested for only ammonia and formaldehyde, following the test, the tester is able to identify and quantify toluene, benzene, and acetaldehyde without repeating the test. This ability to perform post-test analysis for additional compounds will save you both time and money.  FTIR TRUCK The FTIR Truck is a mobile FTIR Testing solution that is rugged and compact with the ability to test in some of the most remote locations. This system is fully integrated with stand alone power generation and has the full capabilities of HAPs testing all inside the shell of a Chevy 2500.  QUALITY ASSURANCE Air Hygiene’s goal is to achieve total customer satisfaction by delivering accurate, on-time analyses that meet each client’s needs. It is our responsibility to provide each client with quality results. This is accomplished by documenting all facets of the analysis, communicating any questionable or out-of-specification results to the client, following procedures and complying with standards, and auditing data internally.

The VOC analysis methodology described in Table 2 of the regulation calls for: “Methods 25A and 18 of 40 CFR part 60, appendix A, Method 25A with the use of a methane cuer as described in 40 CFR 1065.265, Method 18 or 40 CFR part 60, appendix A, Method 320 of 40 CFR part 63, appendix A, or ASTM D6348–03 (incorporated by reference, see §60.17)”.  is capable of meeting this requirement with on-site, real-time data. Our primary option utilizes a VIG 210 VOC analyzer that incorporates the Method 25a and Method 18 technologies into a single analyzer with built in gas chromatograph providing simultaneous data for Methane, Ethane, VOC’s, and Total Hydrocarbons.  can also provide testing by Method 25a total hydrocarbon analyzer coupled with an MKS FTIR analyzer utilizing the Method 320 test technology to determine methane & ethane and provide real-time VOC data. Utilizing either methodology,  is able to provide you with real-time VOC results on-site. Converting emission concentrations (e.g. ppm) to emission rates (e.g. lb/hr, g/hp*hr, tpy) is another important 4J field testing consideration. 4J requires that stack exhaust flow be either physically measured utilizing Methods 1- 4 or stoichiometrically estimated using Method 19 and a fuel flow meter. Method 19 approach when taken, provides a stoichiometric approach typically resulting in stack exhaust flow rates that are anywhere from five to ten percent lower than the manual measurement approach. This is due to both an over dependence on oxygen content for the Method 19 calculations and the human error aspect coupled with the “puffing” of the engine for the manual measurement calculations.
