SUBJECT: Summary of Sulfur Recovery Unit Emission Source Test Reports

I. Purpose

The objective of this documen t is to provide a summary of the Sulfur Recovery Unit

(SRU) emission source test reports received by the EPA from the 2011 Information Collection

Request (ICR) of the Petroleum Refinery industry.

II. Background

On April 1, 2011, the EPA sent an ICR to facilities in the U.S. petroleum refining

industry. The ICR was comprehensive and designed to collect information on processing

characteristics, crude slate characteristics, emissi ons inventories and source testing to bolster our

current data and fill known data gaps. The I CR had four components: (1) a questionnaire on

processes and controls to be completed by all petroleum refine ries (Component 1); (2) an

emissions inventory to be developed by all petr oleum refineries using the emissions estimation

protocol developed for this effort (Component 2) ; (3) distillation feed sa mpling and analysis to

be conducted by all petroleum refineries (Compone nt 3); and (4) emission s source testing to be

completed in accordance with an EPA-approved protocol for specific sources at specific

petroleum refineries (Component 4).

Component 4 of the ICR required source testi ng for twelve different types of emission

sources or units: fluid catalytic cracking units (FCCU), thermal catalytic cracking units, catalytic

reforming units, sulfur recovery units, delayed coking units, fluid coking units, hydrocracking

units, hydrogen plants, asphalt blowing units, fuel gas systems, cooling water systems, and

wastewater treatment systems. This memorandum summarizes the results of the FCCU sources

tests. A similar memorandum is available for the othe r sources required to be tested as a result of

# this ICR. Facilities often claimed specific process information as CBI, and included that

information in the CBI version of the emission sour ce test report stored in the EPA’s CBI office

in Research Triangle Park, NC. However, emi ssions data cannot be claimed as CBI. This

memorandum summarizes and pr esents only non-CBI data.

III. Source-specific Testing Program

Below is a list of the ten facilities required to perform an emission source test on

their SRU.

• Marathon Ashland Petroleum LLC – Garyville, LA (LA3C0610)

• ExxonMobil Refinery and Supply – Baytown, TX (TX3B1160)

• Phillips 66 Company Sweeny Comple x – Brazoria, TX (TX3B1240)

• Valero Refining Company – Po rt Arthur, TX (TX3B1250)

• Shell Oil Anacortes Refinery – Anacortes, WA (WA5A1410)

• Motiva – Port Arthur, TX (TX3B1220) – Recei ved this test report voluntarily from the

facility.

Owners or operators of the FCCU at thes e facilities were requi red to test for:

• Speciated volatile organic h azardous air pollutants (HAP)

• Speciated semi-volatile organic HAP

• Total hydrocarbons, methane, and ethane

• Aldehydes

• Carbon monoxide

• Hydrogen sulfide (H 2 

# S), carbonyl sulfide (COS), and carbon disulfide (CS 2 

# )

• Total reduced sulfur compounds (TRS)

• O 2 

# , CO 2 

# , moisture, and gas flow rate.

The EPA required that the data collected from the emission source testing to be reported

using the EPA Electronic Reporting Tool (ERT). The ERT is a Microsoft® Access database

application. If the facility c onducted testing using a method not currently supported by the ERT,

the facility was required to report the results in the Refinery Testing Supplement, a Microsoft®

Excel spreadsheet. After completing the Refinery Te sting Supplement, the refi neries were also to

submit an electronic copy of the emission te st report, preferably in PDF format.

# 3 IV. Results

A summary of the emission results for the SRU are provided in attached spreadsheet. In

order to better characterize the reported data fr om the emission test reports, detection level

information was provided in the attached summar y spreadsheet. The following designations were

used to describe the detection levels of the reported emissions data.

• DLL = Detection Level Limited = 1 or 2 runs below detection limit

• BDL = Below Detection Limit = All thr ee runs are below detection limit

• No designation = All three r uns are above detection limitSummaryofSRUEmissionTestReportData75-07-0 Acetaldehyde 2.71E-02 BDL 1.70E-04 BDL 8.20E-04 BDL 7.09E-05 BDL 2.72E-03 DLL 2.20E-0250-00-0 Formaldehyde 4.47E-03 1.20E-02 BDL4.28E-03 4.65E-04 DLL 4.83E-03 6.50E-0374-90-8 Hydrogen cyanidePropanalBDL 4.28E-03 BDL 3.00E-02Propionaldehyde BDL 8.22E-05 BDL 1.50E-05 BDL 7.00E-05 BDL 2.71E-037647-01-0 Hydrogen Chloride5.00E-027782-41-4 Hydrogen Fluoride3.70E-0267-64-1 Acetone DLL 3.30E-01 2.24E-01 5.34E-01 BDL 4.70E-02 BDL 1.20E-01750-05-8 Acetonitrile BDL 2.15E-08 BDL 3.00E-02 DLL 1.14E-01 BDL 4.12E-02 BDL 8.41E-09 BDL 7.03E-05107-02-8 Acrolein BDL 2.50E-01 BDL 7.02E-02 DLL 1.22E-02 BDL 3.92E-02 BDL 1.00E-01 BDL 1.85E-05107-13-1 Acrylonitrile BDL 2.15E-08 BDL 2.69E-03 DLL 1.43E-02 BDL 4.14E-02 BDL 7.82E-09 BDL 2.00E-0571-43-2 Benzene BDL 2.40E-01 DLL 1.53E-04 BDL 1.13E-02 BDL 4.04E-02 BDL 1.00E-01 BDL 1.51E-05106-99-0 1,3-Butadiene BDL 1.60E-01 BDL 7.59E-04 BDL5.71E-03 BDL 3.89E-02 BDL 7.00E-02 BDL 1.92E-0575-15-0 Carbon Disulfide BDL 3.00E-02 7.87E-04 BDL 1.13E-02 BDL 1.59E-02 1.00E-01108-90-7 Chlorobenzene BDL 4.29E-09 BDL 5.07E-04 BDL 1.13E-02 BDL 4.70E-03 DLL 1.64E-0998-82-8 Cumene (Isopropylbenzene) BDL 3.35E-09 BDL 1.13E-03 BDL 1.13E-02 BDL 3.51E-03 BDL 1.45E-09106-93-4 1,2-Dibromoethane BDL 5.40E-01 BDL 5.00E-04 BDL 1.13E-02 BDL 1.04E-01 BDL 2.30E-01 BDL 1.61E-05100-41-4 Ethylbenzene DLL 3.28E-09 BDL 1.89E-03 BDL 1.13E-02 BDL 3.58E-03 BDL 1.45E-09110-54-3 Hexane DLL 2.50E-01 DLL 1.07E-03 BDL 9.47E-03 BDL 4.19E-02 BDL 1.00E-01 DLL 1.53E-05IsooctaneBDL 2.89E-03TX3B1220 Motiva PortArthur, TXDL lb/hrLA3C0610 -
