Emission Measurement Methodologies:
Three, one hour tests will be conducted on this engine according to EPA 40 CFR 60 (A) Methods
1-3 & EPA 40 CFR 63 (A) Method 320 for NOx, CO, VOC (as NMNEHC C3) and H2O. Each of
the test runs will consist of readings taken at one (1) minute intervals. Oxygen & CO2 will be
measured using a Fyrite analyzer.
The MKS 2030 analyzer will be operated using a 0.5 cm-1, Medium Norton Beer Apodization
and 60 second averaging.
Based on the compounds that will be measured, the MKS 2030 analyzer has been configured in
the following manner, which is intended to cover all types of natural gas fired engines.
The MKS 2030 software provides a Natural Gas Method that is designed to minimize all
expected interferences by removing the regions in the quant region where they are most absorbed
(i.e. picket fence approach). So, for example, all the water peaks that are greater than about 0.1
abs are removed from the quant region. Since the spectral noise measured (sample spectrum) is
in the range of 0.001 absorbance, it is desirable to have any error within this range. The MKS
software will match the water calibration spectrum to the sample spectrum at any 1 point in the
spectrum to about 1% precision. So, 1% of 0.1 absorbance is 0.001 abs. This is why any peaks
greater than this for interfering compounds are usually excluded so they do not interfere. To
summarize, the MKS software and the method are designed to minimize any interferences by
removing their largest interfering absorptions.
QA spiking procedures will be followed for pre and/or post testing. Various factors often make
determining the exact concentrations for spiking procedures indiscernible prior to testing, even if
the engine has been previously tested. Furthermore, it is infeasible to obtain and transport a
multitude of gas concentrations for varying analytes. Therefore, a mixed gas bottle with a high
enough concentration for multiple engines may be utilized during the spiking procedures. A
summary of all spiking procedures/results will be provided in the final test reports.
The CO2 present in the native sample will be used as the tracer. There are two components that
make up the spike: 90% native and 10% spike. Both the native and spike are being added to the
gas cell and measured simultaneously. Since the CO2 concentration for most engines is very
stable during testing, the reduction in its concentration when a spike is applied can provide very
accurate prediction on the ratio of spike gas to engine emission.
The schematic for our sampling system, which is the same as the system provided in Method
320, is shown below.
The sampling system is used to draw the sample from the stack at an elevated temperature,
remove particulates and push the gas through a secondary heated line into the MKS 2030
analyzer to maintain correct pressure and temperature. There is no reduction in water
concentration or any other component.
Figure 1: Schematic of FTIR Sampling System.
The MKS Multigas 2030 FTIR system inherently converts the wet levels of NOx, CO & VOC to
dry levels and displays the dry levels to the Compliance Specialist(s) via a computer display. The
system is able to perform this conversion due to the FTIR also measuring the moisture content of
the effluent stream. Therefore, it is the dry levels that are typically logged.
Measurement of VOC (NMNEHC C3):
The algorithm currently used for NMNEHC C3 and developed for natural gas fired applications
by MKS instruments in accordance with EPA standards, is the following:
(2.4*c8/(1+exp((2-c8)/0.2))+1.9*c11/(1+exp((2-c11)/0.2))+6*c12/(1+exp((0.5-c12)
/0.2))+2.85*c13/(1+exp((2-c13)/0.2))+3*c14/(1+exp((1-c14)/0.2)))/3
c8= acetylene
c11= ethylene
c12= hexane
c13= propylene
c14= propane
Note: The constants in front of each of the compounds listed represents the FID response factor
when calibrated with Propane.
As with any CEMS analyzer, the FTIR may demonstrate a negative zero bias. The “exp”
functions listed in the algorithm above are intended to mathematically filter out any negative
biases and set them to approach zero.
Engine Operating Parameters:
Operating parameters, where applicable, will be recorded for each 1 hour test which may include
engine rpm, air/fuel ratio setting(s), suction/discharge pressures, ect.
Engine Load Approximation:
Oasis Emission Consultants, Inc. will approximate the engine load using the measured process
parameters, such as gas throughput, suction/discharge pressure/temperature; by correlating the
intake manifold conditions with the engine manufacture heat balance data; or, the engine load.
It is expected that the performance tests will be conducted within ±10% of 100% peak, or the
highest achievable load.
Test Methods:
Oasis Emission Consultants, Inc. will employ EPA Method 320 for NOx, CO, VOC & H2O.
Oxygen and CO2 levels in the exhaust stream will be monitored through the use of a Fyrite
analyzer, concurrently with each FTIR test. All test methods that we intend to utilize are listed on
the following page.
EPA 40 CFR 60 Appendix A, Method 1: Method 1 requires measurement of the various
physical attributes of a stack to establish appropriate sampling locations. An O2 stratification
check will be performed according to 8.1.2 of Method 7E prior to testing to determine
sampling location for engines with stack diameters greater than 6 inches, but less than 12
inches. For stacks equal to or greater than 12 inches in diameter, if the sampling port
locations meet the minimum Method 1 criterion for distance from disturbances, sampling
may be conducted at three points. If sampling ports do not meet Method 1 criterion for
distance from disturbances, stacks equal to or greater than 12 inches in diameter will have an
O2 stratification check performed to determine sampling locations. An O2 stratification is not
required for engines with a stack diameter less than 4 inches.
EPA 40 CFR 60 Appendix A, Method 2: Method 2 provides the means to calculate the
average wet velocity for the exhaust effluent gas. This method employs the use of a standard
or S-type pitot tube, a thermometer and an inclined manometer. The temperature, static &
differential pressures are all used to calculate the average wet velocity. This value may be
used in conjunction with the known stack diameter, and measured moisture content, to
approximate the average dry volumetric flow rate.
EPA 40 CFR 60 Appendix A, Method 3: Method 3 provides the means to calculate the dry
molecular weight of the effluent gas. After passing through a gas condenser, O2 & CO2 gas
concentrations from the effluent stream are measured by a Fyrite analyzer. Measurements
will be taken in conjunction with those from Method 2. The dry molecular weight will be
calculated for each of the test runs.
EPA 40 CFR 63 Appendix A, Method 320: NOx, CO, VOC & H2O concentrations are
obtained by running the engine exhaust through a heated sample line (191 deg C) to an MKS
2030 FTIR analyzer. When a gas sample is introduced in the gas cell, the infrared beam is
partially absorbed by the gas species present. The spectral frequencies absorbed and their
intensity are due to the atoms associated with the chemical bond and the strength of that
bond. The absorption spectrum is unique for each infrared-active gas. The MKS FTIR
analyzer measures the absorption spectrum, and its analysis algorithm measures the
concentration of each gas using pre-loaded calibrations. The MG2000 software allows for the
continuous measurement, display and recording of the sample stream.
