DCC1000 System for Precise detection of Corrosive Contaminants

The METTLER TOLEDO Thornton DCC1000 System offers a new design for conductivity measurement for power cycle chemistry monitoring. By providing conductivity measure-ment in compliance with ASTM D4519, this system provides assurance of water purity to maximize power production and minimize corrosion. Unambiguous measurement of trace levels of corrosion-causing contaminants is enabled with minimal operator supervision.

Benefits

• Faster plant start-ups and simpler turbine warranty compliance

• Easy displaying and monitoring of sample conditions

• Protect the DCC1000 system from thermal damage and maintenance

• Understand plant characteristics better and plan maintenance, avoiding unplanned shutdowns

Features

• Precise detection of corrosive contaminants

• Multi-parameter M800 transmitter with single-screen display of all measurements

• Integrated flow sensor with automatic heater shut-off if flow stops

• Trend graphs for all measurements

ApplicationsFeed water and steam monitoring during plant startup enable the best decisions to be made on increasing load. By monitoring specific, cation and degassed conductivity, the technician can ensure the water quality is adequate to bring the plant online.

Power steam quality monitoring ensures contaminant limits speci-fied in turbine warranties are met. By eliminating interference from CO2 and ammonia, the degassed cation conductivity measures the level of contaminants that turbine manufac-turers are concerned about.

Power condensate monitoringcan help distinguish air in-leakage from cooling water leaks. Any CO2 leakage into the condensate will be detected by comparing the cation conductivity to the degassed cation conductivity on the DCC1000 Analyzer.

The M800 even includes the option for CO2 concentration readout based on this difference, according to ASTM D4519.

DCC1000 System for Conductivity and Contamination Detection

With accurate and reliable conductivity measurements using UniCond sensors with ISM, the DCC1000 System confirms water purity to maximize power production and minimize corrosion.

Conductivity – a key measurementConductivity measurement is the method for determining the concentration of dissolved ionicspecies present in sample water. Ul-trapure water is very poorly ionized with conductivity as low as of 0.055 uS/cm. Even if a small amount of contaminant (for example, NaCl) is added, the conductivity increases substantially. Such salts are corro-sive and their levels need to be mon-itored to ensure minimal corrosion.

Importance of identifying corrosive contaminants An increase in conductivity also oc-curs with the addition of water treat-ment chemicals, such as ammonia or amines, which are not corrosive. These chemicals, and therefore their conductivity effects, are removed using a cation resin column. Along with corrosive contaminants and ammonia, the sample water may also contain carbon dioxide, which is far less corrosive. This adds to the

conductivity measurement and ob-scures the actual conductivity from key corrosion-causing contaminants such as chlorides and sulfates. By using de-gassed cation conductivity to remove carbon dioxide interfer-ence a more accurate picture of the levels of chlorides and sulfates is provided (figure 1).

Optimized design to meet the challenge The DCC1000 System uses the latest technology in conductivity measurement to accurately and reli-ably measure conductivity at each stage of sample conditioning to give insight into the cycle chemistry (figure 2). UniCond sensors used in the DCC1000 are the best available for the measurement of conductivity in pure waters, giving the great-

est accuracy at the lowest levels of detection. With ISM features such as having the measurement circuit close and inseparable from the sen-sor elements, the UniCond sensor can deliver enhanced accuracy and greater range of measurement. The DCC1000 System measures the conductivity after the cation resin column as well as after degassing to provide comprehensive informa-tion on various contaminants in the

water. The degassing is accom-plished by raising the sample water temperature to near boiling which releases the CO2 from the water (the CO2 is released through the unit’s vent tube). The sample water is then cooled and the conductivity measurement of that sample water measures the actual levels of corro-sion-causing contaminants such as chlorides and sulfates remaining.

The Thornton 2800Si Silica Analyzer is a reliable on-line instrument designed specifically for pure/ultrapure water treatment and power cycle chemistry monitoring. This Analyzer provides assurance of water purity to optimize water production and to minimize silica deposition in power plant turbines as well as disruption in semiconductor processes. Early detection of trace contamination is enabled with minimal operator supervision.

ApplicationsUltrapure water monitoring at ppb silica levels can assure the highest quality water is being delivered. Sil-ica breakthrough from polisher anion resin or EDI is detected at very low ppb levels and contaminated water can be diverted before it reaches critical areas.

Benefits• Provides excellent repeatability and saves operator time

• Assures measurement stability

• Allows measurement of additional samples for QC checks in other areas of the plant • Provides convenient analyzer status at a glance, saving operator time

• Safely protects reagent containers and components from plant environment

• Reduces maintenance time

• Enables use with sample sequencer

for multi-stream measurements

Features• Automatic, unattended calibration

• Automatic zeroing with every measurement

• Convenient grab sample capability

• Simultaneous display of silica and measurement timing

• Full enclosure

• Large reagent containers enable a

long service interval

• End of measurement relay signal

Pure/ultrapure water treatment anion exchange monitoring detects the first breakthrough of silica to trigger regeneration before contaminationreaches subsequent treatment stages.

Power steam quality monitoring protects turbines from silica depo-sition and resulting imbalance, loss of capacity and efficiency. Silica measurement and control may also be needed to meet turbine manu-facturer warranty requirements.

Power condensate polisher monitoring can detect the need for regeneration at low ppb levels before feedwater is significantly contaminated.

2800Si Silica Analyzer Reliable Operation

Silic

a An

alyz

er

The measurement is made, the dis-play and outputs are updated and the cycle repeats. The operator can configure the measurement interval to optimize the tradeoff of response time vs. reagent consumption. The 2800Si conforms to ASTM Test Method D7126.

The measurement incorporates Intelligent Sensor Management® ca-pability which stores identification, calibration and additional sensor data within the sensor. The mea-suring circuit is built into the sensor which then sends a robust digital signal to the readout module.

CalibrationThe 2800Si performs a zero cali-bration before each measurement cycle. An automatic span calibra-tion is performed at scheduled intervals (monthly is typical) using a known silica concentration stan-dard. The calibration cycle may also be initiated manually. InstallationThe analyzer is provided with a full dust and drip resistant locking en-closure that protects the reagents and measurement components from the plant environment.

OperationIn the analyzer the sample passes through an overflow assembly that assures a fresh up-to-date sample is always available at the start of each measurement cycle. A rinse period purges the previous sample from the reaction/measurement chamber and fills it with the current sample. The measure-ment is zeroed. Then, reagents are metered in and reaction time allowed to produce a color change proportional to silica concentration. Where phosphates are present, an additional reagent is included to minimize its interference.

Power condensate monitoringcan detect very small leaks earlyto allow time to plan corrective action before the leaks grow and require shutdown. Condensate pol-ishers can also be monitoredfor breakthrough.

compensator are shared with the sodium measurement. The sample then passes to drain.

Electrodes incorporate Intelligent Sensor Management™ capabil-ity which stores all identification, calibration and real-time predictive maintenance data within the sen-sor. The measuring circuit is also built into the sensor which elimi-nates high impedance connections and potential signal loss.

CalibrationThe 2300Na offers both automatic and manual calibration options.

Automatic calibration is accom-plished at concentrations close to the operating range. The 2300Na uses robust, relatively concentrated standard solution which is less vulnerable to contamination. This standard is automatically diluted to lower concentrations using the

double known addition method. The automatic calibration timer schedules periodic unattended calibration or calibration can be initiated from the keypad.

The manual calibration mode uses one or two standard solutions and directly calibrates at those concen-trations. The standards have high enough concentration that trace contamination is minimized.

InstallationThe analyzer is provided witheither a partially enclosed case for easy access to controls for use in a clean sample room, or with a full dust and water resistant lockable door for plant floor installation.

The 2300Na complies with ASTM Test Method D2791.

OperationThe sample passes through an overflow assembly that assures precise pressure and flow regula-tion. The flowrate is set by a needle valve and rotameter at only 40 mL/min, saving pure water and reagent. Diisopropylamine vapor diffuses into the sample without contamination through gas-perme-able tubing.

The reagent raises the pH of the sample to approximately 11 pH to enable the ion-selective electrode to respond only to sodium ion concentration. The sample passes through the sodium sensor flow tube and into the larger flow cham-ber containing a combination probe including the reference electrode, a pH electrode and temperature com-pensator. The pH electrode mea-surement provides confirmation that the correct amount of reagent has been added to the sample. The reference and temperature
