OVERVIEW

Dew Point Tester

Description

Bureau of Mines-Type Dew Point Tester (Standard)

When a gas-water vapor is cooled with no liquid water present, the absolute hu-midity of the vapor content remains constant but the relative humidity increases until it reaches 100% saturation, after which moisture begins to condense. The temperature at which condensation is first detected is known as the dew point. The Bureau of Mines-type dew point tester duplicates the conditions required by the definition of dew point. However, the measurement method is modified so that it is suitable for measuring dew point at high pressures. This is done by enclosing a mirror upon which moisture or hydrocarbons condense (when chilled by a refrigerant) in a pressure chamber. A window in the chamber allows viewing of moisture condensation.

ChanScope

The digital ChanScope provides state-of-the-art temperature measurement of the dew point of pressurized gas. The ChanScope retains all of the proven reliabil-ity and quality of the original Bureau of Mines-type dew point tester and gives instantaneous feedback using an LEDreadout during a test.

Both the standard (Bureau of Mines type) dew point tester and the ChanScope include a sample pressure gauge and tripod socket for ease of use in the field.

All AMETEK Chandler dew point testers meet ASTM D1142-GPA 2140 standards.

NOTE

Theory of Operation

Water contamination in gases can cause corrosion and other equipment problems, especially in regulation and metering stations. The determination of hydrocarbon contamination in pipeline gas is necessary to meet hydrocarbon dew point speci-fications in natural gas transportation contracts. Gases most frequently tested for water content include natural gas, sour gas, heat treating furnace gas, and indus-trial gases such as nitrogen, oxygen, hydrogen, and other bottled gases. The most accurate and widely used instrument available for determining water content is the Bureau of Mines-type chilled mirror dew point tester. When this instrument is used properly, measured dew point accuracy is ± 0.2°F.

Each dew point tester incorporates a pressure-tight chamber to contain the gas or vapor test sample and valves for controlling gas flow. There is a clear plastic win-dow at one end of the chamber to observe the interior and the mirror. The mirror itself is highly polished stainless steel and is attached at its center to a copper thermowell. A chiller attached to the thermowell controls expansions of refriger-ant and the temperature of the mirror. The greater the flow rate of refrigerant, the lower the temperature. The mirror’s temperature is indicated by a thermometer and uses a bulb that is located close to the back surface of the mirror. An elec-tronic Resistance Temperature Detection (RTD) is used on some model dew point testers.

Overview | 1-3

Additional Equipment

Chiller

There are three types of chiller devices available for use with the standard dew point tester or the ChanScope.

• Standard Chiller• Quick Chiller• Liquid Nitrogen Chiller

The Quick Chiller and the Liquid Nitrogen Chiller allow much faster dew point determination but there is an increased risk of error and temperature overshoot if components are not allowed to reach thermal equilibrium.

• The Quick Chiller can be used for dew point measurements down to -20°F (-30°C) with propane, and down to -90°F (-70°C) with liquid CO2 refriger-ant.

• The Nitrogen Chiller is a dipstick type and can be used with liquid N2 for dew points down to and below -200°F (-130°C). The Nitrogen Chiller can also be used with dry ice/acetone for dew points down to -100°F (-75°C).

Certified Thermometers

Certified thermometers that have been tested for accuracy are also available. They are supplied with calibration traceable to NIST.

Illuminated Magnifier

A four-power, prefocused magnifier is available as an option, and can be attached to the instrument to illuminate and magnify the mirror. The battery-illuminated magnifier ensures optimum accuracy of dew point determinations regardless of field lighting. These illuminated magnifiers are available for the following dew point tester models: Model 13-075 (large window, 1000 PSIG) and Models 13-100 (small window, 3000 PSIG), and 13-110 (small window, 5000 PSIG). The magnifier is a simple design and is easy to operate. It is held on the dew point tester using an O-ring.


Glycol Filter

Glycol vapor contained in a gas that has passed through a glycol dehydrator will condense on the tester’s mirror complicating observation of water dew point. A glycol filter assembly can be installed in the tester to remove the glycol vapor before the contaminant enters the instrument. The filter is especially useful when the glycol condensation temperature is above the water dew point.

Tripod

The tripod is lightweight, rigid aluminum. It has two section legs that are extend-able to 54 1/2” for support in the field.

Propane Cylinder

The propane cylinder is a size 20 DOT-approved cylinder with a delivery control valve and a 1/4” male NPT thread. The capacity of the cylinder is 3.75 gallons (14.2 liters) of propane. The cylinder is shipped empty and can be filled at a local gas supplier.

CO2 Bottle

The CO2 bottle is a size 20 DOT-approved cylinder with a dip tube, delivery con-trol valve, and a 1/4” male NPT thread. The capacity of the cylinder is 5 lb (2.3 kg) of CO2. The cylinder can be purchased empty, or full of welding grade liquid CO2.

INSTALLATION AND SET UP

This chapter shows you how to set up your dew point tester. It includes the fol-lowing:

• Inspecting Shipping Contents

• Safety Requirements

• Mechanical Installation- Equipment Required- Tubing and Fittings- Refrigerant Connections- Glycol Filter Assembly- Temperature Display Units (ChanScope only)

• Start-Up- Observing the dew point temperature

Inspect Shipping Contents

The dew point tester and its accessories were inspected before being shipped from the factory. Remove any packing material from the units. Check for dam-age and verify all parts on the packing list were shipped. If any damage is found, notify AMETEK as soon as possible and notify the shipper.

All equipment is calibrated and tested prior to shipment.NOTE


Safety Requirements

• Vent the sample gas to a safe area to prevent the possibility of creating an explosive atmosphere in an enclosed area.

• Always wear safety glasses when working with refrigerant and high pressure gases.

• Do not exceed the pressure rating of the instrument. Refer to Chapter 2 “Specifications”forinstrumentoperatingpressures.

If operating pressure is exceeded, component “blow out” could result in serious injury to the operator.

• Clean the instrument prior to using it with oxygen.

• FormodelsequippedwithChanScopedigitaldewpointindicators:

Do not expose the battery or internal electronics to temperatures higher than the range -20°C to 70°C (-4°F to 148°F). Battery packs should be recycled at an appropriate facility for Ni-MH batteries. Use only Chandler part #13-1274 batteries as replacements. Using other battery packs will cause damage to the electronics and void your warranty.

Use extreme caution if you are using the instrument with oxygen or any other explosive gas reactive to oil. The entire instrument and all sample tubing must be thoroughly cleaned.

No utilities are required for the standard dew point tester. The Chan-Scope requires 100-265 VAC, 50/60 Hz for the battery charger.

NOTE


Mechanical Installation

Tools/Equipment Required

• 7/16”,1/2”open-endedwrenches,10”adjustablewrench

• Isopropyl alcohol (99.5% pure)

• Cotton balls or swabs

• Air duster

• Teflontape

• Refrigerant: propane, liquid CO2 or liquid nitrogen- Liquid CO2 requires using a siphon dip tube cylinder so that low-speci-

Installing the Dew Point Tester

Anadjustabletripodisavailableformountingthetesterwhenusedinthefield.

Observe the following precautions when setting up the instrument and doing test-inginthefield.

• Takearepresentativesample.Werecommendthatyouuseasampleprobeinserted into the center 1/3 of the pipeline. The probe should be inserted in a horizontal, straight run of pipe. It should also be located at least ten pipe di-ameters upstream and downstream from any turbulence causing devices such asanelbow,valve,orificemeter,etc.

• Ensure that the temperature of the sampling line and the dew point tester are above the dew point temperature of the gas in the pipeline. Heat-traced sample tubing may be required in cold ambient conditions.

• Ensure that the sampling line does not contain any condensed liquids such as water, hydrocarbons, glycol, etc.

• There must be no appreciable reduction in pressure between the gas source and the dew point tester.

Connecting the Refrigerant

Once the dew point tester sample connection to the gas supply is properly set up, you must connect the refrigerant valve to a cylinder of propane, liquid CO2, or otherliquefiedgasthatwillbeusedasarefrigerant.

Open the valve on the cylinder and invert it so that the liquid refrigerant is available at the chiller. If you are using a siphon dip tube, you do not have to invert the cylinder.

• Propane is a satisfactory refrigerant for dew point temperatures down to about -20°F (-28°C).

• Liquid carbon dioxide (CO2) may be used for temperatures down to -80°F (-62°C).

• For lower dew points you must use liquid nitro-gen (Figure 3-1).

OPERATION

To prevent serious injury or incorrect measurements, adhere to all test procedures when setting up the tester and performing tests in the field.

Using Glycol Filters

When using the standard dew point tester, there may be times when glycol vapors are present as you are measuring the dew point in the gas. These vapors can lead to difficulty in determining the water dew point because the glycol vapors also condense on the mirror, making observation of the water dew point difficult or uncertain. A glycol filter can be used with the dew point tester under these circumstances to remove the glycol vapor to make it easier to determine the true water dew point.

The filtering material in the glycol filter absorbs both water vapor and glycol va-por. However, though it quickly becomes saturated with water vapor, it continues to absorb glycol vapor for a somewhat longer time. It is during this latter period that water dew points can be determined satisfactorily since once the filter is water saturated, no more water vapor is removed from the gas and the dew points will be the same if read without the filter.

Determining Equilibrium

When the sample gas is introduced at the side of the pressure chamber, it flows through the glycol filter before entering the tester. The filter material should not cause a drop in pressure at normal flow rates. However, you must allow sufficient time for the filter material to attain equilibrium with the sample gas pressure. The time required to reach equilibrium depends on the concentration of water and glycol in the gas and the density of the filter material in the cartridge. Equilib-rium is determined by running preliminary dew point tests. Two consecutive test results without glycol masking of the mirror indicate that the tester is operating normally.


Test Precautions

These precautions must be observed to prevent serious injury and to ensure ac-curate measurements.

1. Vent the sample gas to a safe area to prevent the possibility of creating an explosive atmosphere in an enclosed area.

2. Always wear safety goggles when working with refrigerants and high -pres-sure gases.

3. Do not exceed the pressure rating of the tester.

- Models 13-100/13-1200 tester maximum working pressure is 3000 PSIG (20.7 mPa).

- Models 13-075/13-1175 tester working pressure is limited to 1000 PSIG (6.9 mPa).

- Models 13-110/13-1210 tester working pressure is 5000 PSIG (34.5 mPa).

Working pressure must not be exceeded as this can result in compo-nent “blow out” causing serious injury to the operator.

4. Clean the tester properly before using oxygen.

5. Take a representative sample using a sample probe inserted into the center 1/3 of the pipeline.

6. Ensure that the sampling line does not contain condensed water, hydrocar-bons, glycol, etc.

7. Ensure that the temperature of the sampling line and the dew point tester are above the dew point temperature of the sample gas. When the atmospheric temperature is below the dew point temperature of the tester or the gas in the pipeline or tank, the tester and sample line should be heated with a flexible heat tape to avoid condensation between the gas source and the instrument.

8. Ensure that there is no appreciable reduction in pressure between the gas source and the dew point tester.

9. If you have installed a filter to remove glycol from the gas, the material in the filter absorbs both glycol and water. The filter usually becomes saturated with water within five minutes but continues to absorb glycol. Only after the filter is saturated with water can you make accurate dew point readings.

Operation | 4-3

Use extreme caution if you are using the tester on oxygen or other explosive gases reactive to oil. The entire instrument, including the sample line, must be thoroughly cleaned. Testers that have been ordered “cleaned for oxygen” from the factory will have an oxygen pressure gauge installed and will be tagged with the date they were cleaned.


Test Procedure

Follow this procedure in the ordered sequence to ensure accurate readings.

1. Open the sample inlet valve and purge the tester by flowing the test gas through the sample chamber to expel all the air.

2. Regulate the flow of the test sample by partially closing the outlet valve and then adjust to ensure that the sample flows continuously at full sample pres-sure through the chamber.

3. Adjust the outlet valve so that the gas sample can just be detected on your fingertip. An aspirator bulb or vacuum pump can be used to bring atmospher-ic or low-pressure samples past the mirror.

A low flow of approximately 5 SCFH is recommended.

4. ChanScope For models with a digital dew point indicator, verify that the decimal point at

the far right side of the display is not blinking.

A blinking decimal point indicates that the tester is in pause or hold mode. When in this mode, the displayed temperature is “frozen” and will not change until you press the HOLD button. The HOLD button is a pushbut-ton or mementary switch; press HOLD at any time to ENTER or EXIT this mode.

5. Open the refrigerant valve periodically for a few seconds; allow sufficient time between valve openings to lower the mirror temperature. You can make a quick observation to determine an approximate dew point. However, for the final determination, you should lower the temperature at a rate of no more than one or two degrees per minute.

6. Observe the mirror and thermometer/digital readout at the same time and note the temperature at which a spot of moisture first appears at the center of the mirror.

7. Allow the mirror to warm up and note the temperature at which the moisture spot disappears.

8. Repeat Steps 5 and 6 until the temperatures observed are within 2°F (1°C).

9. Record the mean or average temperature observed as the dew point.

NOTE

Operation | 4-5

Confirmation of Dew Point

In extreme cases, water dew point determination can be difficult, even after the gas has passed through a glycol filter. An alternate method for determining if the dew point is water is to operate at a different pressure.

Example:

1. A dew point determination is done in the normal manner at 1000 PSIG and a dew point of 30°F is obtained. Plotting on the “Saturated Moisture Content of Natural Gas as a Function of Temperature and Pressure” chart (Drawing 13-0097) obtains a water vapor content of 6.3 lb/million cubic feet.

2. Pressure in the tester is reduced to 300 PSIG by partially closing the inlet valve and adjusting the outlet valve to obtain the approximate same flow rate.

3. A dew point determination is now run at this reduced pressure.

If a dew point of 9°F is obtained, you can be sure that the original determina-tion at 1000 PSIG was correct since the water content remained the same (6.3 lb/MMscf) with the change is pressure and dew point. The water dew point is lowered as the pressure is lowered, but the water content of the gas remains the same. Had the water content been different at the second pressure and dew point, then one of the dew points might have been a hydrocarbon, glycol or alcohol dew point.

Interpretation of Dew Point Temperature

Dew points can be converted to water content using Drawings 13-0095, 13-0097, and 13-0125 found in this manual. The ASTM tables are also included.


Differentiating between Water and Hydrocarbon Dew Points

Sometimes, the hydrocarbon dew point of the gas will be the same or higher temperature than the water dew point. In this case, the two dew points must be differentiated.

• The hydrocarbon wets the mirror and the film expands in an iridescent ring to cover the mirror’s surface, or appears as a waterfall of droplets that appear to be pouring from the mirror’s center.

• The water condensate remains concentrated in the center of the mirror.

You can also verify the substance on the mirror by determining the dew point at a lower pressure.

NOTE

Operation | 4-7

Special Test Procedure for Propane

Dew point tests of commercial propane are usually made at atmospheric pres-sure instead of at full sample flow as with other gases. Therefore, when testing propane, the procedure for opening and closing the valves should be reversed to ensure atmospheric pressure inside the tester.

Commercial propane is usually considered “dry” if the dew point is -15°F or lower when measured at atmospheric pressure.

Press HOLD button on the front panel to resume normal operation.


troubleshooting deW Point readings

ProbleM cause solution

Haze on entire monitor obscures dew point.

Possible glycol contamination. Install glycol filter.

Condensed water in sample line.

Temperature of sample line and tester below the temperature of sample gas. Not using a probe to sample gas, slugs of water entering the sample line from the pipe wall.

Heat trace sample line. Purge line with dry nitrogen. Avoid excessive fittings, gauges, etc., in sample line that may be difficult to dry down after condensation. Use sample probe.

Low dew point using glycol filter.

Moisture equilibrium in glycol filter not yet reached.

Glycol filter requires time to saturate with water. Allow to saturate for 5 to 10 minutes.

CO2 and propane refrigerant not chilling to specified temperature.

Using gas instead of liquid. Using a regulator on the cylinder.

CO2 cylinder must be a siphon dip tube cylinder. Propane cylinders must be inverted. Do not use a regulator.

Unable to distinguish water dew point from hydrocarbon dew point.

Both dew points can occur at a lower, same, or higher temperature depending on hydrocarbon components present and the amount of water.

Hydrocarbon dew point wets the mirror with an iridescent ring followed by condensing droplets. This is your dew point. Viewing the hydrocarbon dew point at an angle to the mirror can be helpful. The water condensate begins at the mirror’s center and moves outward across the mirror.
