Emissions Sampling Process
PROCESS DESCRIPTION
The Caterpillar G35088 LE (691 hp @ 1 ,400 rpm) and Caterpillar G3516 LE (1 ,380 hp
@ 1,400 rpm) reciprocating compressorengines are fourstroke, lean burn, naturalgas
fired intemal combustion engines, equipped with an Oxidation catalyst, driving gas
compressors. The eneryy released during the combustion process drives gas
compressors, raising the pressure of the incoming gas fom an initial "suction" state to
a more compressed "discharge" state.
EMISSIONS TESTVEHICLE
The ETG has conducted emission tests on reciprocating engines and turbines for many
years. Thb testirg erperience has enabled the ETG to des(1n and assenble an accurate
and versatile emissions test vehicle (ETV). The ETV is one of three environmentally
controlled boxtrailers housing allanatyzers, computers and auxiliary equipment.
A Data Acquisition Control System (DACS) scans instrument outputs and the data is
transfened to a computer fcr analysis and storage. The computer monttors the readings in
reaFtime and outputsthe data averagesto a video rnonitorand the had drive. The readings
are recording and represented in Central Slandard Tirne (CST) due to our headquarters
located in Houston, Te>ras.
SAI\IIPLING SYSTEM
Continuous analyzers will be used to determine the oxides of nitrogen (NOx), carbon
monoxide (CO), non-methane, non-ethane, including formaHehyde rolatile organic
compounds (VOC), and orygen (Oz) en$ssion concentrations. Available instrumentation
and analyzers are listed in Table 3. Brand names and specific models are for refurence
only and instruments of equal nominal performance may be substituted fom time to time.
Exhaust gas enters the system through a stainless steel probe and a 3-way sample vahre
assembly. The sample is transported via a heat-traced Teflon sample line throuqh a
stainless steelsample pump and into a minimum contacl condenser specially designed to
dry the sample. The sample is then passed through 3l8" Teflon tubing to a Balston
Microfiber coalescing filter and then to the sample manifold. The sample manifold is
maintained at a constant pressure by means of a pressure bypass regulator. Stainless steel
needle valves control the sample flow to each analyzer. See Figure I for the flow
schematic.
Forthe FTIR analper, the erhaust gas is brought into the trailerthrough the same stainless
steel probe and $way sample valrre, however, it is next direc{ed through a heated sample
line to the FTIR hotboxwhere the tempenature, pressure and florru rate are kept constant by
way of a pressure regulator, temperature c,ontroller and needle-valre flow meter untilthe
sample enters the analyzer. Afterthe sanple has passed through the analyzer, it is purged
outside of the trailer. See Figurc I forthe flow schemath.

INSTRUMENT CHECKS AND CALIBRATIONS
The follouring instrument checks ard calibrations guarantee the integrity of our sampling
system and the acarracy of our data.
EPA MToooL GAsEs TflrcFMOI APPEIEN A - U7E.7.I I
Calibration sheets for EPA Protocol 1 calibration gases will be available at the test site and

The measurement system will be first prepared for use. Each analyzer will be set to
the conect response and that response will be recorded by the data acquisition system.
A calibration curve will then be established to convert each analyzer's response to
equivalent gas concentrations as introduced to each analyzer. Then zero, mid and
high calibration gases will be introduced without adjustment to the analyzers and their
responses will be recorded. These linearity checks will be performed daily, and these
responses will be considered acceptable if they are within +l- 2 percent of the span.
This curve will remain unchanged throughout the test. The analyzer calibration checks
(linearity) sheets will be included in the test report APPENDIX.
tlOz ro ]lO Gonv=nsor Errrc-rrcv ({lGfmO, Appemx A -fr7F-8.?Al
An NOz to NO conrersion efficiency test will be perfrcrmed on each day of testing follouring
the procedure described in 40CFR60, AppendixA, Method 7E Sedion 8.2.4.1. The results
of the conversion efficiency test will be included in the test report APPENDIX.

The sample line is leak checked before and after the test by dosing the calibration valve
assembly while the sample pump is openlting. Once the maximum \Ecuum is reached
(approximatety 12 - 15 inches of nnrcury) the valve on the pressure side of the pump is
dosed (See Figure l) thus sealing ofi the vacuum sedion of the sampling system. The
leak tests for each unit will be consirlered acce$able if the rnacuum gauge redirE dmps by
an amount less than 1 inch of mercury over a period of 1 minute. The results of the sample
line leak checks will be included in the tes{ report APPENDX.
Besponse TrrE TEsr (4(rcFR6O, ApprxDx A - il7E.8.261
Beture sampling begins, it will be determined if the high-level or mld-level calibration gas
best approximates the emissions and the more approffie gas will be used as the upscale
gas. A response tinre test will be performed by first introducing the zero gas into the sample
system at the outlet of the probe until all readings are stable. The calibratkrn rahre willthen
be switched to sample the upscale gas at the outlet of the probe until a stable reading is
obtained, within 95% of the certified value of the upscale gas. The upscale response time
will be recorded. Ne*, the low-level gas will be introduced in the same m€rnner as the
upscale gas. Once a stable reading b noted, within 5% of the certified value of the upscale
gas, the downscale response time will be recorded.
This process will be completed once per analyzer to determine upscale and downscale
responses. The greater of the upscale or downscale respnse will be classified as the
response time and all test points will be npnitored for a period of time at least twice the
response time. The results of the response time tesB will be included in the test report
APPENDIX.
Svsreu Bns Gxpcx (4OCFB6O, AnRe{ox A - tl7E.8.2.5 & U7E.8"51
Before sampling begins, the upscale gas is determined as mentioned in the ResponseTime
Iestsection. The system bias check is corducted once priorto and once folhring the test
runs of the series and consists of first inhoducing the NOx anatyzefs upscab gas direc*ly
at the analyzer. The analyzer is alloured to stabilize and the reading noted. The same gas
is introduced at the probe, passing through the entire sample train to the analyzer and the
reading noted. The resulting readings indicate any bias attributed to the sample train. This
process is repeated with the NOx analyzefs low gas. The bias check is acceptable if the
direct gas reading of the ana[ger is wilhin +l- 5o/o of the complete sample train reading of
the analyzer [per 7E.13.2].
This same procedure is repeated for CO and the Oz analyzers. Sample system bias check
forms will be included in the test report APPENDIX.
Bias checks before and after each test run of the series will be used to determine a low and

VOGfrmrrpn
VOC concentratbns will be determined using ASTM D6348. The instrumentation for this
test program is an MKS MultiGas 2030/MAX-iR FTIR analyzer. To determine compliance
with the emission standard, the FTIRwillbe used to measure the pollutant concentration on
a wet basis then convert the concentnation and exhaust flow to a dry basis using the FTIR
moisture determined during the run.

EMISSIONS TESTING
Slpt.r LocanonEIoSET{P
A single point probe consisting of 3/8 inch stainless tubing open at one end will be used
to collect the sample. The sampling point in the erfiaust stack will be at least eight
stack diameters downstream fom any disturbance and at least two stack diameters
upstream from any disturbances as specified in Method 1, 40CFR60, Appendix A. lf
these criteria cannot be met, the sample probe will be placed at least two stack
diameters downstream and a half diameter upstream fom any flow disturbance
(40CFR60, Appendix A, tvttd 1 , 11.1.1) or as needed to ensure a high integrity sample
fom each engine's exhaust.
DErmilAnor oF S:rRATHGAnot l4(rcFR6O, Apranm A - t7E8"l.2l
A stratification check will be performed on units C-161, C;162, C-252 and C-253 using
the sample probe. Three points on a line passing through the centroidal area will be
used, spaced at 16.70/o, 50.0olo and 83.3% of the measurement line. The sampling
time will be at least twice the system response time at each traverse point.
Reciprocating lnternal Gombustion Engines with circdar Strcks
ln orderto ascertain the presence or absence of stratification on engines wilh circular stacks,
e*raust concentr:ations of Q will be measured at three points on a line passing through the
centroidal area of the erfiaust duct. The nrean concentrations will be used to determine the
amount of stratification. lf the concentration at each traverse point differs from the mean
concentration fur all traverse poinb by no rrtorc than t 0.39o difierence of mean
concentration the gas stream will be considered unstratffied and sarnples will be collecied
from a single pointthat nnst closely matches the mean. lf the 0.37o criterion is not met, but
the concentration at each traverse point differs from the rnean concentnation for alltrawrse
points by no more than * 0.5% difierence of mean concentration the gas stream will be
considered minimally stratified, and samples will be taken fom three points, spaced at
16.70/o, 50.0% and 83.3% of the measurement line. lf the gas stream is found to be
slratified because the 0.5olo criterion for a 3-point tesl is not met, twelve traverse points will
be utilized for the test, in accordance with Table 1 -1 or Table 1-2 of 40CFR60 Appendix A,
Method 1.
FuelGasAxnvss
A fuel gas sample will be taken during the testing. The sample will be analyzed by a
pipeline gas chromatograph. This analysis will give the actualspecific gravity and BTU
so that fuel flow and mass emissions can be accurately calculated. The analysis will
be included in the test report APPENDIX.
COFL'TrcETESil RrrIS
The exhaust gas from the engines will be sampled continuously to determine NOx, CO,
VOC and 02 concentrations for three {3} individual sixty {60} minute test runs @ 2
90% of rated (or @ > 90o/o of highest achievable) load. lt would be inaccurate to estimate
the anticipated production capacity of the engines prior to the day of testing due to the
rariability in daily pipeline corditbns.
Other important pararneters such as compressor suction and discharge pressures,
engine speed and ambient conditions will be monitored during the test. Catalyst
measurements such as inlet catalyst temperature and the pressure drop across the
catalyst will be obtained during the test if available.
The data acquisilion system will scan the analyzers every second during the test run.
The computer will average the outputs every ten seconds and the raw data will be
included in the report. A summary of the data, wilh each test run averaged will be
given in the test report APPENDIX.
Any emissions limit exceedance will be reported in accordance with permit and
applicable regulatory requirenrents. if there is an emission limit exceedance, a twenty
(20) minute run will be recorded in as found state. Afier the twenty minute run,
conective actions willtake place to resolve the issue. lf the issue can't be resolved, the
unit will be shut down and the test will be re-scheduled.
