Instrumentation for a safe and reliable carbon capture process
Capture CO₂ emissions while retrofitting existing plants with advanced process instrumentation
Introduction
Innovative amine absorption-based carbon capture process
CCUS is crucial for reducing the carbon footprint of industrial facilities, capturing CO₂ emissions from power plants and factories that rely on fossil fuels. Carbon capture units can be retrofitted to existing power stations, industrial plants and central hubs. This minimizes downtime and maximizes impact in hard-to-abate sectors like cement, steel, refineries and chemicals. Explore our advanced measurement technology to overcome carbon capture challenges and reach your sustainability goals.
Optical analysis
Optimize your carbon capture process with optical analysis
Chemical absorption based on amine solvents is the leading carbon capture technology. Process challenges include amine losses, degradation and energy efficiency leading to reduced profitability. Endress+Hauser Raman analyzers enable real-time monitoring of CO₂ capture solvent quality and offer the following benefits:
Replace tedious off-line analysis
Predict the total CO₂ and amine concentrations in changing process conditions
Monitor variation of solvent quality and degradation to reduce loss
Bring the lab into the process with the Raman Rxn2 mobile cart
Level measurement
Prevent reboiler overload with precise level measurement
A typical process unit comprises contactor (absorption) and regeneration (distillation) columns. Maintaining effective level control in these columns is crucial for stable operation. Holding a constant level and a steady rich amine flow rate is essential to avoid reboiler overload. Guided wave radar technology offers accurate level measurement to achieve:
Reliable measurement even with changing product and process conditions
Zero maintenance: no moving parts
Easy commissioning and diagnostics from HistoROM data management
For high temperature and high pressure applications in the oil & gas, chemical and power industry
Temperature measurement
Protect amine solvent quality and heat exchanger efficiency with temperature control
Maintaining accurate temperature is critical in the amine solvent-based carbon capture process. Temperature differences beyond the stipulated limits between the flue gas and amine stream entering the contactor column can result in gas condensation, foaming and losses. Additionally, reliable monitoring of temperature across the heat exchanger walls is required to detect fouling and improve reliability. Temperature measurement in the regeneration column ensure the quality of amine is maintained and prevents amine degradation. Our instrumentation ensures:
Flexible design with standard terminal heads as per DIN standards
Ultra-fast response time thanks to special thermowell tip
Metric RTD thermometer with connecting cable for use in many process and laboratory applications
Liquid analysis
Improve process efficiency by ensuring the water quality
Optimal CO₂ capture requires precise pH control in amine scrubbing to ensure maximum CO₂ absorption. The quality of water used for making an amine solution is essential for operational efficiency. Deionized or distilled water prevents issues like foaming, corrosion and plugging, ensuring maintenance-free operation. Our Memosens-based water quality analyzer offers the following benefits:
Inductive coupling of cable sensor and cable for energy and data transmission in harsh environments
Memosens digital technology for all relevant sensor and process data
Enhanced sensor design against reference poisoning
Special electrolyte gel for maximum chemical resistance
Memosens 2.0 pH electrode for chemical processes and poisoning media
Flow measurement
Ensure accurate amine flow measurement
Flow measurement in the carbon capture process is necessary for monitoring and controlling process efficiency. Excessive circulation may result in increased fuel consumption, exceeded reboiler capacity and amine losses. Multivariable flow measurement technology provides:
Increased plant safety and data integrity thanks to Heartbeat Technology
Best-in-class diagnostics coverage – developed according to IEC 61508
Multivariable measurement – mass and volume flow, density, temperature, entrained gas detection
Compact installation – no inlet/outlet run requirements
