### Source & Sampling Location Description

# SECTION 2 – SOURCE & SAMPLING LOCATION DESCRIPTION

2.1 Nitric Acid Plant Process Description Nitric Acid is produced through a series of chemical reactions that occur between air, ammonia, and water. At the St. Helens facility this process takes place in three steps: 1) combustion, 2) oxidation, and 3) absorption.

During combustion, ammonia is first heated, mixed with air, and passed through a platinum gauze catalyst, where the ammonia

- air mixture is burned to f orm nitric oxide gas. The nitric oxide gas is then cooled in a series of heat exchangers for oxidation to nitrogen dioxide. After nitrogen dioxide gas is formed, it leaves the heat exchangers and enters the bottom of the absorption column. As the nitrogen dioxide enters the tower, it flows upward through water held in trays. This forces the gas to bubble up through the water introduced at the top of the tower. As the gas and water come into contact, the nitrogen dioxide is absorbed into the water to form ni tric acid.

The strength of the nitric acid produced is determined by the amount of water added to the top of the tower. The St. Helens facility produces 58% nitric acid for use as a feedstock in the Ammonium Nitrate Plant. Any gases that pass through th e tower without being absorbed are sent to a non

selective catalytic reduction unit. This unit uses purge gas from the synthesis to loop to combust both NO x 

## and N 2 

## O into elemental N 2 

## and H 2 

## 0 before being vented to atmosphere.

The nitric acid tail gas ve nt stack has an inside diameter of 23 .5 inches and is equipped with two (2 )
4- inch test ports which are located 90 degrees apart . The test ports are located greater than two (2) stack diameters upstream and approximately eight (8) diameters downstream fro m any disturbances

# SECTION 4 – SAMPLING & ANALYTICAL PROCEDURES

All sampling and analytical procedures used in this test program are based on procedures published by the EPA. These sampling and analytical procedures are contained in the July 200 9 edition s of the EPA document Title 40, Code of Federal Regulations, Part 60 (40 CFR 60), Subparts A and Appendi x A as published by EPA

. Copies of these methods are available from the EPA EMTIC electronic bulletin board or the Code of Federal Regulations which can be obtained online

.

**•** Metho d 1 Sample and Velocity Traverses for Stationary Sources

**•** Method 2 Determination of Stack Gas Velocity and Volumetric Flow Rate (Type S Pitot Tube)

**•** Method 3A Determination of Oxygen and Carbon Dioxide Concentrations in Emissions from Stationary Sources (Ins trumental Analyzer Procedure)

**•** Method 4 Determination of Moisture Content in Stack Gases

**•** Method 7A Determination of Nitrogen Oxide Emissions from Stationary Sources (Ion Chromatographic Method)



## 4 .1 Traverse Point Location (EPA Method 1) The procedures spe cified by EPA Method 1, "Sample and Velocity Traverses for Stationary Sources", were followed to determine the number and location of traverse points used for the velocity traverse. The number of straight run stack diameters (equivalent diameters) upstrea m and downstream from the sample ports was used to determine the minimum number of traverse points required

.
During each Method 4 test, the sample probe tip w as moved to each of the traverse points in each of the applicable test ports. A copy of the st ack sche matic with the actual traverse points is included in the final report.

4 .2 Stack Gas Velocity and Volumetric Flow Rate (EPA Method 2) The procedures specified by EPA Method 2, “Determination of Stack Gas Velocity and Volumetric Flow Rate (Type

- S Pitot tube), are used to determine the stack velocity and volumetric flow rate. These procedures are slightly modified when performed as part of Method 5 tests. The sample probe, including a Type

- S pitot tube and K

- Type thermocouple, are position ed at ea ch traver se point. The Pitot tube differential pressure and exhaust gas temperature data were recorded on field data sheets. The Pitot tube w as connected to an inclined

- vertical oil manometer and the thermocouple w as connected to a digital readout. The thermocouple and readout devices have been calibrated in accordance with USEPA Emission Measurement Centers Approved Alternative Method Alt

- 011 requirements after field use.

4.3 O 2 

## & CO 2 

## Concentrations (EPA Method 3) For this test program, TRC continuously collected percent O 2 

## and CO 2 

## concentrations per EPA Method 320. A copy of the raw data is included in Appendix D of this test report. For each t est run, the molecular weight of the stack gas was calculated per Method 3 based on concurrent O 2 

## and CO 2 

## st ack gas concentrations.

4.4 Moisture Content (EPA Method 4) The moisture content of the stack gas was determined gravimetrically from the weight gain in each

### Sampling & Analytical Procedures

5 

## impinger and the weight gain of the silica gel impinger from the Method 4 sampling train s

.

4.5 NO x 

## (EPA Method 7A ) Collection of NO x 

## samples were performed according to EPA Method 7A. Two

- liter borosilicate round bottom flasks with short necks and 24/40 standard taper joint. A digital

- type thermometer capable of measuring 1° C (2°F) intervals fr om - 5° to 50° C (25° to 125° F) was fitted into the thermal wells on each flask. A mercury manometer was used to measure pressure. Due to the low moisture of the flue gas, an unheated probe was used. A check was made before testing to ensure that there was no moisture condensation on the probe or stopcock.

The flasks were prepared for sampling by pipet t ing 25 mL of absorbing solution into each sample flask. The absorbing solution was prepared by adding 2.8 mL of concentrated H 2 

## SO 4 

## to 1 liter of deioniz ed (DI) water following by adding 6 mL of 3% H 2 

## O 2 

## . The absorbing solution was prepared one day prior to sampling. Also, each flask was cleaned prior to the absorbing solution being added.

For sampling, each flask valve and the valve was turned to it’s e

vacuate position and evacuated to less than 3” Hg of absolute pressure. The pump valve was turned to its vent position, and the pump was turned off. The volume of the flask and the valve, flask temperature, and barometric pressure were recorded. The abs olute internal pressure in the flask was equal to the barometric pressure less the manometer reading. Stack gas pulled through the probe past the flask by a pump filling the probe with stack gas. The flask valve was immediately turned to the sample posit ion, and stack gas was permitted to enter the flask. Sampling was stopped with vacuum due to the insufficient oxygen present in the flue gas stream (< 4% O 2 

## ). Ambient air was then introduced to allow for sufficient O 2 

## in the conversion of NO to NO 2


## .

Aft er collection, the flasks were shaken for at least 5 minutes and allowed to sit for at least 30 hours. The flasks with the samples inside were shaken again for at least two minutes. The flask samples were then transferred to polyethylene bottles.

The sa mples were analyzed by EPA Method 7A by Chester LabNet in Tigard, Oregon. Emissions results were reported in μg and μg/mL of NO per sample. The results were then converted to ppm. Appendix C contains the Chester LabNet laboratory data.

To arrive at the final NO x 

## results, a correction factor was applied to the analytical results. Samples of two known protocol gas concentrations were collected and analyzed using EPA Method 7A. Appendix D contains the correction factor used for the samples. The average percent difference between the Method 7A results and the protocol gas values was used a correction factor to adjust to the flask sampling results. The corrected results were used in any subsequent calculations.
