Report on Emissions Testing of Pressure Assisted LRGO-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 address 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 tables 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

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 measurements. Also, identify which compounds 

were analyzed by the PFTIR. 

The information desired in both requests is available in the excel spreadsheet titled 

“2013_02_13_JZ_Dow_Data_Reduction_Workbook_Final.xlsx”. 

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 P2L 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) 99.90 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 supplied in the tables on the following page. 

Correction: 

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

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

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

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

time stamps of 4:01:00 pm and 4:05:58 pm.
