# 1. INTRODUCTION

**The U.S. Environmental Protection Agency (EPA), Office of Air Qual ity Planning and** 

**Standards (OAQPS) issued an Information Collection Request (ICR) t o Holcim (US), Inc (Holcim).** 

**Under the authority of Section 114 of the Clean Air Act (CAA), the E PA requested information on** 

**hydrogen chloride (HCl) emissions from nonhazardous waste-burning kilns at Portland cement** 

**manufacturing facilities. The request was in response to comment s from Portland cement industry** 

**members and its trade association to EPA’s proposal to amend t he national emission standards for** 

**hazardous air pollutants for Portland cement manufacturing (74 FR 21136 (May 6, 2009)).**

**Holcim retained DEECO Inc. (DEECO) to conduct the required emissi ons testing. Testing** 

**for HCl was conducted in accordance with EPA Method 321 - Measurement of Gaseous Hydrogen** 

**Chloride Emissions At Portland Cement Kilns by Fourier Transform Infrared (FTIR) Spectroscopy.** 

**The Holcim facility in Florence CO (3500 Hwy 120, Florence, Colorado 81226) has been one** 

**of the Portland cement manufacturing facilities selected as pa rt of the ICR. Holcim operates a dry** 

**process kiln system at this facility.**

**Facility operations include the mining of the raw materials, t he operation of the raw mill for** 

**material processing, the operation of an alkali bypass syste m, the production of clinker in a dry kiln,** 

**the operation of a clinker cooler, and the operation of finish mills for the production of cement. The** 

**kiln and calciner are fired on coal, tire derived fuel (TDF), natural gas, and/or used oil**

**.**

**Airflow from kiln is directed to the Raw Mill, then to fabri c filters (main baghouse) for** 

**particulate removal, then to the wet scrubber for SO**

**Airflow from the clinker cooler is directed to fabric filters (cooler baghouse) for particulate removal** 

**before exhausting out the main stack. Airflow from the coal mill is directed to fabric filters (coal** 

**mill baghouse) for particulate removal, and then directed to the ma in stack. Airflow from the Alkali** 

**Bypass System is directed to fabric filters (Alkali Byp ass Baghouse) for particulate removal, then** 

**to the scrubber and on to the main stack.**

**Testing was performed at the stack under two conditions, Raw Mill On and Raw Mi ll Off,** 

**on March 30 th**  

# and 31 **th** 

# , 2010. A summary of the test results is shown in Table 1.1.

**Sampling was conducted by personnel from DEECO, Inc. of Raleigh, North Carolina.** 

**Emission measurements were conducted simultaneously at the Main Ki ln Stack for temperature,** 

**volumetric flow rate, dry gas molecular weight, moisture, and hydroge n chloride. A summary of the** 

**sampling and analytical methods are presented in Table 1.2.**

# 3. SAMPLING AND ANALYTICAL PROCEDURES

**Table 1.2 presents a summary of the overall sampling and analytica l protocols used for the** 

**Information Collection Request (ICR) test program for the Main K iln stack at Holcim (US), Inc.’s** 

**Florence, CO facility. All sampling and analytical methods employed for this test program were** 

**performed in accordance with the procedures outlined in the Reference Test Methods contained in** 

**the Code of Federal Regulations , Title 40, Part 60, Appendix A (40 CFR 60, Appendix A) and 40** 

**CFR 63, Appendix A.**

3.1 EPA Method 1 and 2 - Stack Gas Volumetric Flow Rate Determination

**The Main Kiln stack was a round vertical duct with an inside diamet er of 236.19 inches. The** 

**sampling ports were located on the Kiln stack over 6.6 duct diameter s above the nearest disturbance,** 

**and more than four duct diameters below the stack discharge. This location meets the minimum** 

**specifications for selection of a measurement site as outlined in EP A Method 1 (see Appendix B).** 

**A schematic of the Main Kiln stack is shown in Figure 3.1.**

**An 8-point velocity traverse in each of two perpendicular directions was made at each** 

**sampling location using a type-S pitot tube in accordance with EPA Method 2. Gas temperatures** 

**were measured using calibrated Type K thermocouples and digital readout devic es.** 

**Dry gas molecular weight was determined using the oxygen and ca rbon dioxide** 

**measurements following EPA Method 3A employing oxygen and carbon dioxi de monitors. Stack** 

**gas moisture was measured in accordance with EPA Method 4 procedures.**

3.2 EPA Method 4 - Stack Gas Moisture

**The moisture content of the flue gas was determined using the met hodology described in** 

**EPA Method 4. Based on this method, a known volume of particulate-free g as was pulled through** 

**a chilled impinger train. The weight of each impinger was determined g ravimetrically before and** 

**after sampling. The weight increase in each impinger was t hen related to the volume of gas sampled** 

**to calculate the moisture content.**

**During this test, the moisture content of the flue gas was determ ined simultaneously with the** 

**Methods 3A and 321 sampling.**

# 8 **Figure 3.1 Schematic of the Main Kiln stack.**

# 9

3.3 EPA Method 3A - Stack Gas Oxygen and Carbon Dioxide

**A CEM system was used for determining the flue gas molecular weight and stack gas oxygen** 

**content on the Main Kiln stack.**

**The extractive monitors require that the effluent gas sample b e filtered and maintained above** 

**condensation temperature, or conditioned to eliminate any possible i nterference (i.e., water vapor** 

**and particulate matter), before being transported and delivered t o each analyzer. All components of** 

**the sampling system which contact the sample are either of g lass, stainless steel, or Teflon. A heated** 

**sampling probe with heated out-of-stack particulate filter, he ated sample lines, an ice water-cooled** 

**condenser, a sample pump, and a gas distribution manifold are used to deliver a representative** 

**sample of flue gas to each of the analyzers. Details of the major components of the measurement** 

**system are presented below.**

3.3.1 Gas Sampling System

**The gas sample was extracted from the stack through a glass lined probe and filter heated to** 

**at least 356** E 

# F in an enclosure custom built for these test procedures. This **heated enclosure was**

**equipped with heated glass-lined probe that allowed three traver se points on the line at 0.4, 1.2, and** 

**2.0 meters from the stack wall be sampled equally during each test. The glass filter holder had a** 

**teflon frit supporting a quartz fiber filter. Outflow of gas from the heated filter enclosure was** 

**conveyed using a heat-traced Teflon sample line also maintained at least at 356**  E 

# F. The heated line

**was connected directly to the FTIR sample cell. A sample pump i n a DEECO proprietary chiller** 

**type gas conditioner system was used to pull the gas sample t hrough the system. The gas conditioner** 

**system was also used to remove moisture from the gas sample p rior to introduction to the** 

**oxygen/carbon dioxide analyzer.**

3.3.2 Oxygen and Carbon Dioxide Monitor

**A CAI Model 200 O**

**2** 

# /CO

**2** 

# analyzer was used to measure the oxygen and carbon dioxide

**concentrations. The oxygen concentrations are were measured using the paramagnetic technique.** 

**Because of its sp3 electron orbital distribution, an oxygen mole cule has an unpaired electron and** 

**hence displays a magnetic orientation. Since other elements that display this magnetic phenomenon** 

**are not common gasses at normal temperatures, the paramagnet ic measurement technique is virtually** 

**specific for oxygen. The sample gas flows through a detection ce ll located in a very strong magnetic** 

**field. The magnetic nature of the oxygen causes the oxygen to move to one side of the detection cell,** 

**inducing a pressure differential proportional to the oxygen concentration in the detector cell. The** 

**analyzer measures this pressure differential, converts the pre ssure differential to an electrical signal,** 

**and sends the results as output.**

**The carbon dioxide concentrations were measured using a single-beam photometr ic system** 

**with a micro flow sensor detector. The micro flow detector is a sealed unit filled with carbon dioxide.** 

**The instrument consists of an infrared light source, a chopper, a me asuring cell and a micro flow** 

# 10

**detector filled with carbon dioxide. The infrared light emitted b ackward is reflected by a reflecting** 

**surface and is added to the infrared light emitted forward. Arrang ed between the infrared light source** 

**and the measuring cell is a chopper blade which rotates to modulat e the infrared light beam at regular** 

**frequency. The modulated infrared light beam thus formed passes thr ough the measuring cell filled** 

**with a sample gas where the light energy is partially ab sorbed or attenuated before it reaches the front** 

**chamber of the detector. Both the front and rear chambers of the de tector are filled with the gas** 

**component to be measured. The infrared light energy is partiall y absorbed in the front chamber and** 

**residual light is absorbed in the rear chamber, thereby incr easing the pressure in both chambers.** 

**Since the detector is designed to produce a pressure difference b etween the front and rear chambers,** 

**a slight gas flow is produced through a path connecting these chambe rs with each other. This slight** 

**flow is converted into an AC electrical signal by a micro flow sensor.**

3.3.3 Data Acquisition System

**Data were recorded on two separate devices. A hard copy was o btained using a Molytek 2702** 

**strip chart recorder. Data was also recorded to the hard disk of an IBM compatible computer utilizing** 

**the serial output of the Molytek recorder in conjunction with custom s oftware developed by DEECO** 

**Engineers. Data for each of the analyzers was sampled each t wo seconds with a one minute average** 

**being written to disk. Data was further averaged over the test period and corrected for calibration** 

**error and drift using a spreadsheet program.**

3.3.4 Calibration Procedures

**Calibration procedures were performed in accordance with EPA me thodology. Analyzers** 

**were calibrated before and after each test and a calibration check was done between each test run.** 

**The pretest calibrations consisted of the following steps:**

C **Internal (direct) calibration of each analyzer to adjust calibrati on and** 

**check linearity.**

C **External (through the entire sampling system) calibration to c heck the** 

**system bias on zero and span gases.**

**The post test calibration consisted of an external system bias calibr ation check** 

**Each analyzer was calibrated using a certified zero and span (mid or high range) gas. Zero** 

**and span gases were directed to each analyzer through the appropr iate plumbing, the calibration gas** 

**flow rates were adjusted to the correct flow rate and the analyzer w as adjusted with the appropriate** 

**span pot.**

**After the analyzer was properly adjusted the linearity wa s checked using a low and high range** 

**calibration gas. The maximum allowable limit for linearity is 2% of the analyzer range. All analyzers** 

# 11

**were shown to be linear within these limits.**

**The external calibration bias check was performed by placing the CE M system in sampling** 

**mode and injecting a zero and span gas into the sample line at the probe exit. This check shows if** 

**there is any sampling system related bias, and also serves a s a check of the integrity of the sample** 

**line.**

**DEECO used EPA Protocol and/or ±2% NIST Traceable gases f or calibration as required by the** 

**various reference methods employed in this test program. Calib ration gases were selected from** 

**previous experience with similar sources and/or from information o btained from the facility engineer** 

**prior to sampling. In some cases if the gases that were se lected were out of the optimum range of** 

**operation then no significant impact of data quality is expecte d due to the linear nature of the** 

**analyzers that were used.**

**No audit gases were available from federal or state agency.**

**At the completion of the pretest calibration routine, the CEM sy stem was ready for operation.** 

**No further adjustments of sample flow rates, analyzer zero or span adjustments, or other critical CEM** 

**operating parameters were made until testing and post test calibra tion were complete.** 

**At the completion for each test run, calibration gases were used to check betwe en test runs.** 

**A zero and the upscale calibration gas closest to the actual emission concentrations were used for the** 

**pretest and post test calibrations.**

3.4 EPA Method 321 - Stack Gas Hydrogen Chloride

**The sampling system described above was used to convey the gas s ample to the FTIR sample** 

**cells. The FTIR sample cell was maintained at 356** E 

# F. The sample cell was connected to a MIDAC

**Corporation I-series Fourier Transform Infrared Spectrometer and Detect or.** 

**The FTIR spectrometer measures vapor phase organic or inorganic compounds which absorb** 

**energy in the mid-infrared spectral region, about 400 to 4000 cm -1**  

# (25 to 2.5 μm). Continuous

**measurement is made by matching sample absorbance bands with bands in reference spectra, and** 

**comparing sample band intensities with reference band intensities.**

**The principle limitation to FTIR spectroscopy are the pres ence of interfering compounds that** 

**also absorb energy in the mid-infrared spectral region. In a c ement kiln stack gas matrix, water vapor** 

**(H**

**2** 

# O) and carbon dioxide (CO

**2** 

# ) are the primary interferents that must be incorporated **into the**

**identification and quantitation method.**

**The FTIR software performs the computation for a single compou nd by subtracting all the** 

**other compounds (interferants and target) from the absorbance spe ctra and quantifies the single** 

**compound based on the remain absorbance. The FTIR software provides a Standard Error** 

# 12

**Calculation (SEC) value that is an indication of how well the identi fication and quantitation has been** 

**performed. A high SEC indicates that other interferants have not b een accounted for in the analysis** 

**method, and a low SEC is indicative of greater confidence measurement.**

**The instrument was operated with a resolution of 0.5 cm -1**  

# with 4x zero filling. Beer-Norton

**Medium apodization was used with amplitude phase correction. Five ana lytical regions were used for** 

**HCl; 2748.85 - 2754.20 cm -1**  

# , 2772.80 - 2776.80 cm **-1** 

# , 2795.80 - 2800.20 cm **-1** 

# , 2962.50 - 2964.0 cm **-1**



# , **and 2997.0 - 2998.60 cm -1**  

# . These regions were found to provide the lowest SEC values for thi **s stack**

**gas matrix.**

**With this system at the 0.2 ppm detection limit required in the ICR, a M aximum Analytical** 

**Uncertainty (MAU) of 0.15 ppm at cell conditions was calculated. The ICR request that the detection** 

**limit be calculated according to Method 321. However, Method 321 does not have provisions for** 

**calculating a detection limit. The method has the analyst sp ecify the detection limit and then** 

**determine if the data quality of the analytical system meets calculated criteria based on the desired** 

**detection limit. The MAU of 0.15 ppm is less than the 0.2 ppm required detection limit, indicating** 

**that the FTIR system is suitable for measurement at this level.**

**Analyte spiking was conducted before and after each sampling run a ccording to Method 321.** 

**The results are summarized in Tables 3.1 and 3.2. All analyte s pike recoveries were within the** 

**required 70-130% and the pre and post test CTS calibration checks w ere within the 5% required .** 

**It was apparent that higher spike recoveries were obtained with higher level s of native HCl.**

# 4. QA/QC PROCEDURES AND RESULTS

**The objective of a quality assurance/quality control (QA/QC) prog ram is to assure that the** 

**precision and accuracy of all environmental data generated by DEE CO for clients are commensurate** 

**with data quality objectives (DQO's). DQO's are based on a c ommon understanding of the intended** 

**end use(s) of the data, the measurement process, and the availabili ty of resources. Once DQO's are** 

**established, formally or informally, QC protocol can be defined for the measur ements.** 

**In this project, the final data user will be Holcim. The data quality objec tives in this project** 

**are to generate scientifically sound data to be used for compliance purposes**

**.**

4.1 Sampling Equipment

**All of the sampling equipment used was calibrated according to t he procedures outlined in the** 

**Quality Assurance Handbook for Air Pollution Measurement Systems , Volume III, EPA-600/4-77-** 

**027b.**

4.1.1 Manual Sampling Equipment Calibrations

**For sampling Methods 1, 2, and 4 the procedures and equipment used to measure st ack gas** 

**velocity and temperature measurements and the metering system used to maintain constant rate** 

**sampling conditions and to determine the sample gas volume were su bjected to pretest and posttest** 

**calibrations and/or inspections as required by the appropriate EPA methods**

**.**

Barometer **- Barometric pressure values were obtained from a calibra ted barometer, verified by** 

**phone call to a local airport, and corrected for elevation to sampl e port level (0.01 inches Hg per 10** 

**ft. elevation).**

Pitot Tubes **- Each pitot tube used in sampling meets the design specifi cations for type-S pitot tubes** 

**in EPA Method 2. Therefore, a maximum value baseline coefficient (C** 

**p** 

# ) of 0.84 is assigned to each

**pitot tube. Calibration by the manufacturer for pitot face-o pening alignment included measuring the** 

**external tubing diameter (dimension D**

**t** 

# ), the base-to-opening plane distance (dimensions P

**a** 

# and P

**b** 

# ),

**and the face opening misalignment angles, with all terms as de scribed in EPA Method 2. Pitot tubes** 

**were visually inspected for structural integrity at the completion of each test. Inspection sheets for** 

**pitot tubes are included in Appendix E.**

Calibration Meter and Metering System **- The secondary reference meter equipment arrangement**

**for calibration is shown in Figure 5.7 of EPA Method 5. The prescrib ed procedures were followed.** 

**A wet test meter with a 1 ft 3**  

# /rev capacity and + **1 percent accuracy is used as the primary calibrant.**

**The dry gas meter's pump is run for a minimum of 5 minutes at a flow rate of 0.35 cfm to condition** 

**the interior surface of the wet test meter. Leak checks are performed and if satisfactory, triplicate runs** 

**at each of no less than five different flow rates are done. A calibration curve is prepared and the** 

**meter is recalibrated after 200 hours of operation or annually, whichever comes fi rst.** 

# 15

**The calibration set-up for the dry gas metering system usi ng the secondary reference meter** 

**in lieu of the wet test meter is given in Figure 5.5 of EPA Method 5. A leak che ck of the metering** 

**system before calibration was performed as shown in Figure 5.4 of EPA Method 5. The metering** 

**systems's pump is operated for 5 minutes at an orifice manom eter setting of 0.5 inches H** 

**2** 

# 0 to heat

**up the pump and system to stabilize the meter inlet and outlet temperatures. Values for the orifice** 

**setting (delta H), wet test meter volume (V**

**w** 

# ), corresponding dry test meter volume (V

**d** 

# ), dry test

**meter inlet and outlet gas temperatures (t**

**di** 

# and t

**dn** 

# ), and time are recorded for the initial calibration.

**Then the ratio of the wet test meter to the dry test meter ( gamma) and the orifice pressure differential** 

**that equates to 0.75 cfm at standard conditions (delta H@) are calculated.**

**A post-test meter calibration was made on the dry gas meter used during the test to check its** 

**accuracy against the pre-test calibration. This post-test calibration check was made using the average** 

**orifice setting obtained during each test run and setting the vacuum at the maximum value obtained** 

**during each test run. These test runs were made against DEECO' s secondary reference dry gas meter** 

**which was calibrated against a wet test meter. The calib ration data sheets for the dry gas meters are** 

**included in Appendix E.**

Thermocouples and Digital Indicators **- Thermocouples were calibrated by comparing them agai nst** 

**an ASTM-3F mercury-in-glass thermometer at approximately 32** E **F (ice water), ambient temperature,**

**and at approximately 220** E **F. Each thermocouple was calibrated against temperature ra nges to which** 

**it is typically exposed during test conditions, and they agreed within 1.5 percent (expressed in**  E **R)**

**of the reference thermometer throughout the entire calibration ra nge. Also, thermocouples were** 

**checked at ambient temperature at the test site to verify calibration. T he calibration data sheets for** 

**the thermocouples are included in Appendix E.**

Pretest and Posttest Leak Checks of Sampling Trains **- Each Method 4 sampling train was**

**subjected to pretest leak checks and posttest leak checks. For a ll sampling runs the posttest leak** 

**checks were acceptable (less than 4% of the sampling rate a t the highest vacuum recorded during the** 

**test run).**

4.2 Analytical QA/QC Results

**Analytical measurements of precision and accuracy were made on stack gas samples, and are** 

**summarized in a separate report.**
