2 INTRODUCTION
2.1 PRELIMINARY REMARKS
The primary purpose of power plant chemistry programs is the protection of major capital
components by the prevention of corrosion. Online instrumentation is used to monitor the
presence of potentially corrosive chemicals in the water and steam cycle, thereby giving the
operator the opportunity to take corrective actions to prevent corrosion or depostion of deposits
on the major components in the steam generator or turbine.
Conductivity is frequently used as a water quality measurement. However, the presence of
commonly used chemicals such as ammonia, hydrazine, or caustic can mask the effects of
corrosive species in the water if conductivity is used without further conditioning. Cation or acid
conductivity is used to remove the cationic species from the water by passing the sample through
a resin column containing hydrogen form cation resin.
The presence of dissolved carbon dioxide increases the cation conductivity but does not have any
negative influence on corrosion. For this reason, removing the carbon dioxide from the cation
resin treated sample makes it possible to obtain the cation conductivity value due to the presence
of corrosive species, especially sulfate and chloride. Especially during turbine start-up when there
are large amounts of carbon dioxide present in the steam and condensate, accurate cation
conductivity readings are needed to minimize startup times and meet production goals.
The conductivity measurements in power plants provide indispensable information about the state
of the water-steam circuit. Specific conductivity can be used to infer the pH and Ammonia
concentration. Passing a water sample first through a cation exchange column removes the high
conductivity cations such as NH4+to provide a conductivity value based to the total anion load in
the sample. Frequently, there is enough dissolved carbon dioxide in a sample to provide a false
“high” cation conductivity indication, so removing the carbon dioxide becomes the final step in
providing an accurate cation conductivity value.
The new 9096 Degassed Cation Conductivity Analyzer from Waltron removes carbon dioxide
using a desorption column. Using this method, 93.5% of the CO2is removed in the 45 seconds
the sample is in the desorption column. Another advantage of this approach is that there is no
requirement for either a Nitrogen source nor for a heater to boil off the CO2as was done with the
original reboiler units.
2.2 WORKING PRINCIPLE
As the sample passes through the cation exchanger, the ions from the process treated sample
water (eg. Ammonium NH4+) are removed. Next, the ions present due to gaseous components
must be removed. These gaseous components from the atmosphere are introduced into the
sample during the process and through leaks in the water - steam cycle. Of the atmospheric
gases, only carbon dioxide (CO2) dissolves in the water sample to chemically form ions. The
remaining gases (oxygen, nitrogen, etc.) dissolve physically and do not form ions and thus do not
contribute to conductivity. The chemical reactions of carbon dioxide in water are shown by the
following equations:
A) CO2+ 2 H2O HCO3-+ H2O + H+pK = 6,3

Introduction
12
Waltron User Manual 101-046-B.3
9096 Degassed Cation Conductivity Analyzer
B) HCO3-+ 2 H2O CO32- pK = 10,3
Thia is a pH-dependent equilibrium. At a pH value of 5, 94% of the carbon dioxide is present as
CO2gas and 6% as carbonate ion HCO3-. Following the cation exchanger, the pH is about 5.5-6,
so there is almost exclusively CO2gas. The bicarbonate ion (HCO3-)is practically non-existent.
These are the ionic components of the carbon dioxide but are much less corrosive than the ions
of the salt-containing components. In order to obtain a selective conductivity value for the salt
ions (maximum potential risk for corrosion), the carbon dioxide has to be removed from the water
sample. For this separation process, an inert gas (gas that does not contain CO2) passes through
the sample and the gas components are displaced by the gas components of the inert gas in the
sample. Thus, the inert gas drives the carbon dioxide from the sample. In this way, the CO2
contribution is removed from the cation conductivity.
The removal of carbon dioxide is carried out in an exchange column using a counterflow
principle. The aqueous sample flows into the head space in the column and moves under gravity
downwards. Inert gas flows from the bottom upwards in the column and escapes from the
headspace to the outside. The inert gas is produced from decarbonised air. In the column an
exchange process takes place in which the carbon dioxide is driven off from the liquid. With the
circulating pump and a valve, a sample flow rate of 5-8 l / h is maintained . In order to achieve a
constant liquid level in the column, a constant head bypass is installed.which also prevents back
diffusion of carbon dioxide from the atmosphere into the column. A conductivity cell in the
sample output measures the degassed cation conductivity (DCC).

3 INSTALLATION
3.1 RECEIVING
The Waltron 9096 Desgassed Cation Conductivity Analyzer is assembled and fully tested for
proper performance. Before proceeding with analyzer installation, it is recommended to:
Check that the box and analyzer have not been damaged during transportation.
Take extreme care during analyzer unpacking and moving.
Be careful not to misplace accessories during unpacking. Refer to the included packing
list.
3.2 ANALYZER HANDLING
Take extreme care when lifting or moving the analyzer. Before moving the analyzer, it is
recommended to manually empty all of the liquid containing components.
3.3 LOCATION AND MOUNTING
It is recommended to install the analyzer in a suitable position:
The location is to be clean, covered and properly enclosed to provide the analyzer with
good ventilation and low dust concentration.
Operating environmental conditions are: temperature between 0 and 60°C (32-140°F) at
max 80% relative humidity. If the temperature is below 0°C, the analyzer should be
installed in a heated cabinet.
Place the analyzer close to the sample point to achieve the minimum response time; the
sample should be homogenous and representative.
The drain line should be properly dimensioned and positioned at a downward slope to
allow the drain of analyzed sample (by gravity).
WARNING!
The sample drain of the analyzer must be at ambient
pressure with no restriction or counter pressure.

3.6.1 TRANSMITTER ENCLOSURE
The electronics are housed in the transmitter enclosure which has a protection rating of IP67
(NEMA 6). In order to maintain that level of protection, all communications and power cables
passing through the transmitter enclosure must use the appropriate cable glands.
To gain access to the terminal block connections for power and communications, the lower panel
on the front of the transmitter can be removed by unscrewing the six screws holding the panel in
place.
