Degassed Cation Conductivity Analyzer with EDI Resin Regeneration
SWAN AMI-II CACE DG
Continuous online monitoring of specific conductivity (SC), conductivity after cation exchange (CACE) with ongoing EDI resin regeneration, and degassed conductivity after sample reboiling (DCACE) - ASTM D4519-16 standards.
This advanced system provides a complete solution for the online monitoring of specific conductivity (SC), conductivity after cation exchange (CACE) with continuous electrodeionization (EDI) resin regeneration, and degassed conductivity after sample reboiling (DCACE), all in full compliance with ASTM D4519-16 standards.
Benefits:
Efficient CO2 Removal: The system ensures effective and stable removal of CO2 from the sample, continuously adjusting the heater setpoint based on fluctuations in atmospheric pressure for optimal performance.
Continuous Operation: The system operates without interruption, automatically regenerating the cation exchange resin through electrodeionization (EDI). This eliminates the need for resin replacement, chemical regeneration, and regular maintenance, significantly reducing operational costs.
Integrated Sample Cooling: An efficient sample cooling system is built into the design, ensuring that no hot water is discharged to the drain, further enhancing the system’s efficiency and environmental friendliness.
Application Examples
This system offers comprehensive monitoring of steam and condensate quality in both power and industrial plants. It measures specific conductivity and conductivity after cation exchange, while also simultaneously calculating pH levels and the concentration of alkalizing agents. Additionally, it uses degassed conductivity to detect anionic impurities, such as those separate from dissolved CO2.
Measuring Range
Conductivity: The system measures a wide range of conductivity values, from 0.055 to 1000 μS/cm. It also includes temperature compensation to 25°C, tailored to various substances like strong acids, strong bases, ammonia, ethanolamine, and morpholine.
pH: The system calculates pH levels ranging from 7.5 to 11.5, in accordance with the VGB-S-010-T-00 directive.
Concentration: It can calculate ammonia concentrations between 0.01 to 10 ppm.
Instrument Features
Continuous Operation: The system operates continuously, with automatic regeneration of the cation exchange resin via electrodeionization (EDI), ensuring consistent performance without the need for manual intervention.
CO2 Removal: The horizontal degassing system efficiently and stably removes CO2 from small sample volumes, maintaining sample integrity.
Sample Cooling: The integrated sample cooling system ensures that degassed conductivity measurements are taken at the temperature of the incoming sample, preventing hot water from being discharged to the drain.
EDI Module: The system includes an EDI module with an exchangeable sample chamber module, allowing for easy maintenance and adaptability.
Efficiency: The system is designed to minimize sample flow and electrical power consumption, offering a more efficient alternative to conventional sample reboilers.
Instrument Protection: Optional sample filtration is available to protect the instrument from contaminants.
On-Board Quality Assurance
Sample Flow Validation: An integrated sample flowmeter ensures accurate measurement validation.
Heater Setpoint Adjustment: The system continuously adjusts the heater setpoint based on atmospheric pressure, optimizing performance.
EDI Module Monitoring: The system tracks the operational parameters of the EDI module to monitor the service life of the sample chamber, ensuring long-term reliability.
