1.1 O

VERVIEW

This manual describes the Chemiluminescence (CLD) Analyzer Module of Rosemount

Analytical's NGA 2000 Series of gas analysis components (See Figures 1-1 and 1-2).

The CLD Analyzer Module is designed to continuously determine the concentration of nitric oxide and oxides of nitrogen (NO plus nitrogen dioxide [NO2]) in a flowing gaseous mixture.

The concentration is expressed in parts-per-million.

The CLD Analyzer Module is designed as a slide-in module (if configured in stand-alone instrument fashion), removable from the front of the Platform, with gas connections made from the rear. All electronics relative to sample detection and conditioning are included in this module.

1.2 T

YPICAL

A

PPLICATIONS

The CLD Analyzer Module has specific applications in the following areas:

Oxides of nitrogen emissions from the combustion of fossil fuels in:

Vehicle exhaust

Incinerators

Boilers

Gas

Turbine

Nitric acid plant emissions

De-NOx control system

Nitric oxide emissions from decaying organic material (e.g., landfills).

1.3 T

HEORY OF

T

ECHNOLOGY

The CLD Analyzer Module uses the chemiluminescence method of detection. This technology is based on NO's reaction with ozone (O

3

) to produce NO

2 and oxygen (O

2

).

Some of the NO

2

molecules thus produced are in an electronically excited state ((NO

2

* - the

"*" refers to the excitation)). These revert immediately to the ground state, with emission of photons (essentially, red light). The reactions involved are:

748410-A

I NTRODUCTION

NO + O

3

NO2* + O

2

NO

2

*

NO

2

+ red light

As NO and O3 mix in the reaction chamber, the intensity of the emitted red light is measured by a photodiode and is proportional to the concentration of NO in the original gas sample.

To measure NOx (NO + NO

2

), any NO

2

in the sample is reduced to NO (at <95% efficiency) by being continuously passed through a heated bed of vitreous carbon (this occurs before the sample gas is presented to the ozone). Any NO initially present in the sample passes through this converter stage unchanged before being routed to the reaction chamber.

The photodiode generates a DC current, which is then amplified, conditioned and expressed on the network as the Primary Variable.

1.4 F

EATURES

Among the features included in the CLD Analyzer Module are: 1) ozonator air loss shutoff and 2) NO/NOx mode capability.

NPACKING

If the Chemiluminescence (CLD) Analyzer Module is received as a separate unit, carefully examine the shipping carton and contents for signs of damage. Immediately notify the shipping carrier if the carton or contents is damaged. Retain the carton and packing material until all components associated with the CLD Analyzer Module are operational.

2.2 A

SSEMBLY

If the CLD Analyzer Module requires assembly with other components (e.g., the Platform and associated I/O Modules), do so at this time. Following the guides on the bottom left and bottom center of the Platform, carefully slide the Analyzer Module halfway into place.

CAUTION: HAND INJURY HAZARD

Do not place hands or fingers in the Platform front handles when front panel is open. Dropping the front panel of the Platform while hand or fingers are inside either handle can cause serious injury.

Lift the spring-loaded pins on the front of the Analyzer Module, and carefully slide it the rest of the distance. Secure the module in position by releasing the pins, which seat in the available holes in the bottom of the case (see Figure 2-1). If the module and Platform are difficult to assemble, remove the module, ensure the top cover of the module is firmly seated on the hold-down screws, and repeat the assembly procedure.

Refer to Section 2-4 for electrical connections.

Calibration Gases

Either U.S.P. breathing grade air or nitrogen is recommended for use as zero gas. A mixture of NO or NO

2

in a background of nitrogen is recommended as span gas. For maximum accuracy, the concentration of NO in the span gas should be about the same as that in the expected sample stream.

Ozonator Source Gas

For analyzers with ranges less than 0 to 2,500 ppm, U.S.P. breathing grade air should be used for generation of the ozone required for the chemiluminescence reaction. For ranges greater than 0 to 2,500 ppm, breathing grade oxygen is required.

Sample

The sample must be clean and dry before entering the Analyzer Module. Sample should be filtered for particulates down to two microns, and should have a dew point 5 o

C (13 o

F) below coldest ambient temperature.

NOTE components may occur if this flow level is exceeded.

CAUTION: EXTERNALLY RESTRICT SAMPLE FLOW TO LESS THAN

2200 CC/MIN.

No restrictor is provided in the sample inlet of this module. For those users who cannot externally limit sample flow, accessory restrictor PN 657300 is available from Rosemount Analytical.

To obtain this accessory, call 800-441-7245.

Pressure

Between 690 and 1035 hPa-gauge (10 and 15 psig) of ozonator air (or oxygen, if appropriate) should be present at the rear panel of the module. Bypass sample gas flow rate should be between 700 and 2000 cc/min. with backpressure regulator pressure (see

Capillary Pressure in Current Measurement Parameters menu, which can be viewed by selecting the PARMS softkey in Main Menu) adjusted to 344 hPa (5 psig).

Zero/span gases should be introduced at the SAMPLE IN fitting at normal sample inlet flow rate.

NOTE

At no time should ozonator gas pressure exceed 2070 hPa-gauge (30 psig).

Damage to internal components may occur if this pressure level is exceeded.

Leak Test

The CLD Analyzer Module is completely tested at the factory for gas leakage. The user is responsible for testing for leakage only at the inlet and outlet fittings on the rear panel.

Periodically, the user should do an internal leak test (with a test procedure chosen by the user).

Contaminants

White crystal deposits on the windows of the reaction chamber, and the clogging of capillaries and vent are usually due to sample contaminates such as ammonia reacting with the high ozone levels and NO components.

To eliminate the contaminates, the sampling system should be reworked or a preventive maintenance program developed (if dropout is not excessive). Another source of crystalline formation is contaminated air.

Apply power to the CLD Analyzer Module. If it is associated with a Platform, do this by plugging in the Platform to a power source. The Platform has no ON/OFF power button.

Once power has been supplied to the Platform, the CLD Analyzer Module will be energized.

If the user's system contains only one Analyzer Module, all system components, the

Controller Board and the network "self-install" (bind together) during initial startup. If the system contains more than one Analyzer Module, the startup sequence will interrogate the network to locate and identify all components on the network. The user will have to bind appropriate combinations of components after the startup sequence.

S TARTUP AND O PERATION

It is recommended, after initial startup, that the CLD Analyzer Module is calibrated at least once every eight hours. This practice should continue until experience indicates that some other interval is more appropriate depending on the analytical accuracy required.

If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is initiated, nothing happens), a possible solution relates to the use of an incorrect gas for zeroing or spanning (e.g., using a high concentration gas to zero or a zero gas to span the Analyzer

Module). Simply recalibrating with the appropriate gas(es) will not correct the problem because the ZERO OFFSET or SPAN FACTOR has been set to an extreme value in the process.

To remedy the problem, do the following:

1. Select the following from the Main Menu: Expert Controls and Setup, Analyzer Module

Set Up, and Calibration Parameters.

2. Using the

arrow, select Zero Ranges, press ENTER and, using the up/down arrows, toggle to SEPARATE. Do the same for the Span Ranges selection. Do not press

ESCAPE at any time unless retention of prior settings is desired.

3. Return to the Main Menu and make the following selections: Expert Controls and Setup,

Expert Analyzer Controls, Zero/Span Calibration, FACTORS softkey, and Range 1 (2, 3,

4) Factors (do Steps 4 and 5 for each range).

4. Select Zero Offset, press ENTER, adjust the value to 32700 with the

and

arrow keys, and press ENTER. Do not press ESCAPE at any time unless retention of prior settings is desired.

5. Select Span Factor, press ENTER, adjust the value to 0.00015 with the

and

arrow keys, and press ENTER. Do not press ESCAPE unless retention of prior settings is desired.

6. Attempt to recalibrate the Analyzer Module according to the procedure outlined at the beginning of Section 3.4. If recalibration fails, return to the Range Factors menu, readjust

Zero Offset and Span Factor values, and try calibrating again.

The vitreous carbon converter used in this analyzer module must be checked periodically to assure that it is working at peak efficiency. The efficiency of the converter is typically 95% to

98%, that is, 95% to 98% of the nitrogen dioxide introduced to the module is reduced to nitric oxide. That is well above the 90% minimum required by the Environmental Protection

Agency. (Refer to 40 CFR 60, App. A, Method 20, Paragraph 5.6.)

Two conditions reduce the efficiency of the converter:

the converter is operating at too low a temperature and the efficiency drops or

the converter is operating at too high a temperature and the nitrogen dioxide is reduced to nitrogen, which is not detectable by the chemiluminescence reaction.

Initially, an interval of one week between converter efficiency checks is recommended because high temperature operation changes conditions inside the converter. The active surface area of the vitreous carbon increases through use. Initially, when the surface area is low, the temperature at which converter efficiency peaks is relatively high. This peak temperature moves downscale as surface area increases, and less external energy is required to cause adequate conversion.

The nominal range of converter operational temperatures is 300

°

C to 400

°

C (572

°

F to

752

°

F). The current converter temperature can be located in the Physical Measurement menu by selecting the following from the Main Menu: Expert Controls and Setup, Analyzer

Module Setup and Physical Measurement Parameters.

Follow this procedure to optimize the operating temperature of the converter:

1. Power up the module and allow it to stabilize at operating temperature (about one hour).

2. Check the Converter Temperature in the Physical Measurements menu (as noted above). Note the value for future reference.

3. Introduce a calibration gas of known (NO

2

) concentration into the analyzer and note the concentration value determined when the full response has been achieved.

4. Change Converter Setpoint in the Temperature Control menu to 300

°

C by selecting the following from the Main Menu: Technical Configuration Menu, Diagnostic Menus,

Analyzer Module Diagnostics, Temperature Control Parameters. Allow module 15 minutes to stabilize, recheck the concentration value and note the value for later use.

5. Increase the Converter Setpoint value by 20

°

C, wait 15 minutes, and note the concentration value. Repeat this step until either a converter efficiency of between 95% and 98% is obtained or the final 20

°

C increment produces an efficiency increase of less than one percent.

6. Decrease the Converter Setpoint value by 5

°

C, which places the converter at a temperature suitable for low ammonia interference and efficient NO

2

conversion.

7. Recheck the Converter Temperature value in the Physical Measurements menu, and compare it to the initially recorded value.

NOTE

Converter temperature is not a direct measure of converter efficiency.

Temperature measurement is for reference purposes only.

FFICIENCY

It is the responsibility of the user to measure efficiency of the NO

2

-to-NO converter during initial startup and thereafter at intervals appropriate to the application (normally once a month).

The reactant material used in the converter provides the optimum combination of high conversion efficiency and low ammonia interference. Unlike most competitive analyzers, the

NGA 2000 CLD Analyzer Module utilizes a reactant material that gradually becomes more efficient at a given temperature. Thus, after a period of use, operation at a lower temperature setpoint than initially required is certain.

3.7.1 T EST S ETUP FOR M EASUREMENT OF C ONVERSION E FFICIENCY

A typical setup for measurement of conversion efficiency is shown in Figure 3-7. The test setup includes:

A cylinder of nitric oxide standard gas consisting of NO in N

2

The concentration of NO in the standard gas should be about the fullscale value of the range under test. The test sample supplied to the analyzer should contain a concentration of

NO comparable to that in the samples that are to be analyzed. Alternatively, a higher concentration NO standard may be used if the test setup includes provision for diluting it appropriately with zero air. Suitable standard gases are available from various suppliers.

Stainless steel cylinders are commonly used, but specially treated aluminum is preferred for low parts-per-million NO samples.

20

An ozone generator utilizing an ultraviolet lamp, not a corona discharge

A corona discharge ozone generator is undesirable because it may produce oxygen atoms, which can then combine with atmospheric nitrogen to form NO. The result can be an erroneously high value for the measured conversion efficiency.

3.7.2 T EST P ROCEDURE

1. Measure converter temperature in the sub-menu structure as described in Section 3.6.

Note present reading as a reference for comparison with subsequent readings.

2. Lower converter temperature to 300

°

C as described in Section 3.5, Step 4, and wait 15 minutes for temperature equilibration.

3. (See Figure 3-7) Connect the Model 958 Converter Efficiency Tester to the CLD Module, and follow Steps 4 through 17 below (as adapted from 40 CFR 60):

4. Attach the NO/N

6. Open valve MV2 until the CLD Module SAMPLE Pressure Gauge reaches operating pressure and the BYPASS flowmeter indicates some bypass flow. Wait until stable readings are obtained by the CLD Module.

7. Zero and span the Analyzer output to indicate the value of the NO concentration being used. This value should be about 80% of fullscale. Record this concentration.

8. Open valve MV1 (air supply metering valve) and adjust to blend enough air to lower the

NO concentration (as noted above) about 10%. Record this concentration.

9. Power up the ozonator, and increase its supply voltage until the NO concentration noted in Step 8 is reduced to about 20 percent of the concentration noted in Step 7. Wait for stabilization. NO

10. Switch the CLD Module to NOx mode. Total NOx concentration is now output to the network for display. Record this concentration.

concentration of the dilute NO span gas initially used is displayed. Record this concentration.

12. Close valve MV1. The NO concentration should be equal to or greater than the reading in Step 7. This indicates whether the NO contains any NO

2

.

13. Calculate the efficiency of the NO converter by substituting the concen-trations obtained during the test in the equation below: a - b

% Efficiency = 1 + 100 c - d

Where: a = recorded concentration in Step 10 b = recorded concentration in Step 11 c = recorded concentration in Step 8 d = recorded concentration in Step 9

In the example in Figure 3-7B, the following calculations would apply:

80 - 85

% Efficiency = 1 + 100 = 92%

Efficiency checks should be made on each analyzer range, using an NO span gas concentration appropriate to the instrument range.

Conversion efficiency should be improved.

15. Repeat Step 14 until: a) 95% to 98% efficiency is attained or b) the final 20

16. Reset converter temperature setpoint 5

3.7.3 S UBNORMAL C ONVERSION E FFICIENCY

If a measured conversion efficiency of between 95% and 98% is unobtainable within the normal temperature range, the most probable cause is depletion of the catalytic material within the converter.

However, before concluding that the converter is defective, ensure that the conversion efficiency measurement is accurate. Though the measured efficiency is less than the 95% to

98% range, the actual efficiency may be somewhat higher.

An apparent subnormal efficiency can be due to a problem external to the Analyzer Module, perhaps located either within the test setup or between it and the Analyzer Module. Check the following:

1. Leakage.

2. Loss of NO

2

between test setup and Analyzer Module. Such loss can occur by reaction with a rubber diaphragm in a pressure regulator or flow controller. Stainless steel diaphragms are preferred. Loss can also occur during passage through filter media.

3.7.4 R EPLACEMENT OF C ONVERTER

If the subnormal conversion efficiency is real, and not due to measurement error introduced by the test setup, the converter must be replaced. See Section 4.

The usual cause of converter failure is destruction of a large part of the catalytic material by excessive heat. This is due either to an excessively high temperature setpoint or failure of the converter temperature control circuitry.

3.7.5 C APILLARIES

Replacement vent and pump capillaries should be installed finger-tight. Use of a wrench can constrict capillaries, thus changing flow rate. Sample capillary is metal; use a wrench for tightening.

3.7.6 TEA S CRUBBER

The presence of NO

2

in the NO cylinders can cause inaccurate converter efficiency values.

The TEA Scrubber accessory (P/N NL635741) can be used to remove residual NO

2

from the NO cylinders. Use of this accessory allows an NO

-free NO calibration gas.

PERATION

The CLD Analyzer Module is designed to continuously analyze the sample stream.

Normally, it is never powered off except for servicing or for a prolonged shutdown.

Maximum permissible interval between calibrations depends on the analytical accuracy required, and therefore cannot be specified. Initially, the instrument should be calibrated at least once every eight hours. This practice should continue until experience indicates that some other interval is more appropriate.

The Analyzer Module will not allow the user to increase the upper limit of a range beyond the maximum range software setting. To change the Maximum Range value, select the following from the Main Menu: Technical Configuration Menu, Service Menu, Manufacturing

Data, and Analyzer Module Data. Select Maximum Range, and use the arrow keys to scroll the indicated value. The same applies for the Minimum Range value.

WARNING: ELECTRICAL SHOCK HAZARD

Disconnect power to the module(s) prior to replacing components.

This equipment should not be adjusted or repaired by anyone except properly qualified service personnel.

4.1 OVERVIEW

The CLD Analyzer Module requires very little maintenance during normal operation.

Occasionally, the intake fan screen may require cleaning, refer to Section 4.3.

Also, the detector's reaction chamber and sapphire window may require cleaning, refer to

Section 4.7.

White crystal deposits on the windows of the reaction chamber and plugging of capillaries and vent are usually due to sample contaminates such as ammonia reacting with the high ozone levels and NO components. To eliminate the contaminates, the sampling system should be reworked or a preventive maintenance program developed (if dropout is not excessive). Another source of crystalline formation is contaminated air.

Several components may require replacement. These are discussed in the following sections.

4.2 F

USES

The main power fuse may require replacement.

NOTE Before replacing the fuse, remove power to the Analyzer Module.

See Figure 1-2 for the location of the Power Supply Board main power fuse, which protects

24 VDC input to the module.

Reaction Chamber Removal

Disconnect the stainless steel tubing lines at the Gyrolok fittings. Remove the (4) nuts holding the Detector Assembly to the chassis. Disconnect the plug from connector J1 on the Signal Board and remove the assembly from the chassis.

NOTE

Care should be taken to avoid getting heatsink compound on optical surfaces.

If this substance is removed during the disassembly process, a zinc-oxide-filled, silicone grease (e.g., Dow Corning 340 or EG&G Wakefield

Engineering's Series 120 Thermal Joint Compound) be reapplied in the reassembly of this component.

Although the heater and thermostat can be removed to facilitate handling, contact with the white heatsink compound can be minimized by leaving these items in place. Remove the (2) screws holding the top plate of the Detector , and move the plate along the wires and away from the Detector .

Remove the (2) screws holding the tube assembly in place. Hold the tubing with one hand while inverting the Detector Housing with the other, allowing the Reaction Chamber O-ring and window to be removed from below.

Reaction Chamber Installation

To reinstall, hold the housing in the inverted position while sliding the Reaction Chamber

O-ring and window into position and the tubing into the slot in the housing. Hold the

Reaction Chamber in place while rotating the housing upright. Replace the hold-down screws.

NOTE

The procedure described above is for the purpose of maintaining the relative positions of windows and O-ring to the Reaction Chamber during installation.

Replace the top cap and screws. Reverse the removal procedure to reinstall the Detector

Assembly into the Analyzer Module.

Photodiode Removal

Remove the Detector Assembly as described above. Invert the housing to access the mounting bracket. Remove the (3) screws and shoulder washers from the bracket. Remove the bracket, insulating disk and bottom plate as a unit to minimize the spread of the heatsink compound.

Remove the (2) screws holding the lower section of the Detector Housing, then slide the section along the cable and remove.

Remove the (2) screws holding the socket, thermistor and photodiode in place, being careful not to lose the washers that are used as shims.

Grasp the socket and photodiode base while slowly rotating to separate the photodiode from the housing. Some friction will be felt as an O-ring is used around the photodiode as a seal.

Photodiode Installation

To replace the photodiode, carefully remove the diode from the green socket, and replace with a new one. Before mounting the new diode, the top cap of the enclosure should be temporarily removed and the (2) screws holding the Reaction Chamber loosened about two turns. This allows air which is trapped between the O-ring seals to escape when the diode is inserted. It also maintains the position of the O-ring and window in the upper compartment.

The new photodiode should be slowly inserted into the housing while gradually rotating the body. This allows the O-ring to properly seat. Continue replacing screws, washers, thermistors, etc., with the thicker shim (washer) on the opposite side of the socket from the thermistor.
