# Report on Emissions Testing of Pressure Assisted LR GO-HC

and Steam Assisted SKEC Burners – Supplement #1

John Zink Shop Order: 9136991

Prepared for



# The Dow Chemical Company

Purpose: This supplement has been created to addres s specific requests / questions raised by EPA

during evaluation of the emissions test report.

Requests / Questions:

1. Provide the net heating values used for natural gas , propylene, and hydrogen.

Fuel LHV values reported in tables JZ-1, JZ-2, and JZ-3 are from the TRC gas chromatograph

analysis. TRC used the following LHV values:

Component Btu/lb Btu/SCF

Methane 21520 898.79

Ethane 20432 1615.47

Propylene 19691 2152.00

Fuel LHV values reported in table JZ-3 and the tabl es appearing in pages 25 to 49 of the JZ report

used the measured flow rates and the following LHV values:

Component Btu/SCF Molecular Weight

Natural Gas 899 17.15

Propylene 2153 42.08

Hydrogen 270.6 2.02

# Rev. 0

Document: 9136991-GP0-P07-0008_0 Page 2 of 3 The TRC GC analysis was not able to detect hydrogen . TRC used the JZ calculated fuel heating

value for test P4 in the TRC report.

2. Provide minute by minute data from the PFTIR measur ements. Also, identify which compounds

were analyzed by the PFTIR.

The information desired in both requests is availab le in the excel spreadsheet titled

“2013_02_13_JZ_Dow_Data_Reduction_Workbook_Final.xl sx”.

3. For the tests that were started but were halted due to loss of flame, P2H run 1, P2L run 1 and

P3L run 1, does the data for these tests exist? If so, please supply the data.

Emissions data exists for both the P2H run 1 and P2 L run 1 test series. For the initial run of test

series P3L, the hydrocarbon flow abruptly declined less than a minute into the test run. Since

the actual run time was so short, emissions data is not available. The table below reports the

emissions data from the TRC report (pages 22 to 25)

.

Parameter Pressure Assisted Tests

Test ID P2H run 1 P2L run 1

Combustion Efficiency (%) 99.98 99.74

THC DE (%) (Based on O2 F-Factor) 99.99 99.77

Propylene DE Direct (%) (Based on O2 F-Factor) 99.9 0 99.69

Propylene DE Bag (%) (Based on O2 F-Factor) N/A N/A

Critical Pressure (psig) 11.49 11.61

Pressure at Flare Tip (psig) 13.74 4.88

Exit Velocity at Flare Tip (ft/s) 1021 664

Fuel Gas LHV (BTU/SCF) (GC Analysis) 746 650

Fuel Gas Flow Rate (lb/hr) 7,942 4,835



# The data recorded by JZ for these two tests are supp lied in the tables on the following page.

Correction:

During the investigation to respond to request 3 ab ove, an error was discovered in the TRC

report. Page 22 of the TRC report erroneously indi cates that the P2H-1* start and stop times

were 14:01 and 14:06 respectively. The actual star t and stop times are 4:01:12 pm and 4:09:16

PM as shown on page 83 of the TRC report. This tim e period is in closer agreement with the JZ

time stamps of 4:01:00 pm and 4:05:58 pm.Rev. 0Document: 9136991-GP0-P07-0008_0Page3of3Test P2H Run 1Date TimeFIT 3312Nitrogen lb/hrFIT 3306 NaturalGas lb/hrFIT 3112Propylene lb/hrDPI3112Propylene DP"w.c.TI3111Propylene Temp°FPI3110Propylene SPpsigTotal Fuel Flowlb/hrFuel LHVBTU/SCFPIT 3317 Fuelpressure atburner psigTE 3315 FuelTemp at Burner°F11/20/20134:01:00 PM42560370941.9115540.12796579013.749611/20/20134:02:00 PM42510362440.4615538.99787577913.639511/20/20134:03:00PM42480376942.7616040.84801779913.939511/20/20134:04:00 PM42480371442.0315540.14796179213.709511/20/20134:05:00 PM*42510364040.6215639.15789078213.6895Test Averages42510369141.5615639.85794278913.7495* 4:05:00 contains 59 seconds of dataDate TimeTE 2104CollectorEntrance °FTE 2105CollectorEntrance °FTE 2106CollectorEntrance °FAverage PlumeInlet Temp °FTE-2103 SampleExtraction Point°FCollectorVelocityPressure "w.c.Collector StaticPressure "w.c.Collector FlowSCFHAmbient Temp°FAmbientPressure psiaWind SpeedmphWind DirectiondegAmbientHumidity %11/20/20134:01:00 PM4534254574553770.44-1.5426716014.295.316444.711/20/20134:02:00 PM4884995014914230.44-1.5427486014.294.117145.011/20/20134:03:00 PM4634775155004030.44-1.5327126014.294.117045.211/20/20134:04:00 PM4304824844723830.44-1.5326786014.295.317544.911/20/20134:05:00 PM*4294314834543680.44-1.5326586014.294.617144.9Test Averages4534634884743910.44-1.5426946014.294.717044.9* 4:05:00 contains 59 seconds of dataTest P2L Run 1Date TimeFIT 3312Nitrogen lb/hrFIT 3306 NaturalGas lb/hrFIT 3112Propylene lb/hrDPI3112Propylene DP"w.c.TI3111Propylene Temp°FPI3110Propylene SPpsigTotal Fuel Flowlb/hrFuel LHVBTU/SCFPIT 3317 Fuelpressure atburner psigTE 3315 FuelTemp at Burner°F11/20/20135:23:00 PM28470198314.0214230.0948296824.898311/20/20135:24:00 PM28540196613.9213329.6448206774.838311/20/20135:25:00 PM28570200614.2114330.5148636864.948311/20/20135:26:00 PM*28590194813.4113629.5048076724.8383Test Averages28530198213.9913930.0348356814.8883* 5:26:00 contains 18 seconds of dataDate TimeTE 2104CollectorEntrance °FTE 2105CollectorEntrance °FTE 2106CollectorEntrance °FAverage PlumeInlet Temp °FTE-2103 SampleExtraction Point°FCollectorVelocityPressure "w.c.Collector StaticPressure "w.c.Collector FlowSCFHAmbient Temp°FAmbientPressure psiaWind SpeedmphWind DirectiondegAmbientHumidity %11/20/20135:23:00 PM3773504013962790.44-1.5625286014.297.918853.811/20/20135:24:00 PM3683463663592730.44-1.5725146014.298.318653.711/20/20135:25:00 PM4744394684653610.44-1.5626516014.296.018353.811/20/20135:26:00 PM*3322633313542320.45-1.5624666014.306.316654.1Test Averages3993684044022980.44-1.5625556014.297.318453.8* 5:26:00 contains 18 seconds of data
