  3. Emission Monitoring – why? Main drivers: Energy optimisation Environmental soundness Meeting regulations • Shipping is the primary mode of transportation • NOx, SOx and PM from shipping is a significant portion of global emission • Human health & crops are seriously affected by NOx, SOx and PM • To reduce, control and manage NOx, SOx and PM emission various technologies will be implemented in the coming years. • Thus emission monitoring will be part of the solution CO2 NO - NO2 - PM CO - H2O – SO2

  4. Monitoring Technologies – Schematic Visualization& Reporting Gas sampling at stack Mulitplexing(several lines) Initial gas conditioning Final gas conditioning Transport (sampling line) Gas analysis

  5. Monitoring Technologies – Sampling Extractive CEM Systems • Cold extractive • Hot extractive • Dilution systems In-situ CEM systems • Cross stack light based systems • Probe and point based systems Gas sampling at stack Initial gas conditioning Transport (sampling line)

  6. Monitoring Technologies – Analyzing Methods • Chemiluminescece (CLD) • UV fluorescence • Non Dispersive Infra Red (NDIR) • Electrochemical cells • Lased Detection (TLD & QCL) • Zirconium oxide sensors (ZrO2) Mulitplexing(several lines) Final gas conditioning Gas analysis

  7. Experience gained CLD Proven technology (reference method) Require sample & conditioning systems Slow response time Can only measure NO not NOx High consumable & maintenance requirements A/C unit will normally be required Total high cost of ownership

  8. Experience gained ZrO2 Well-proven – cost effective technology developed for the automotive industry. Real-time measurement with no delays from sample lines, multiplexing, coolers and converters Easy installation, operation and maintenance Total low cost of ownership Measure only NOx and O2, no other gases Sensor degradation by SO2

  9. Emission Monitoring – System Requirements • Robust online measurement • Simple - No conditioning or gas transport • Direct - Accurate Hot gas Measurement • Adaptable to increasing regulation • Low maintenance • Low cost of ownership • Certified to MARPOL annex Vl

  10. Patented IR Principle • Correlated suspect/reference • Superior ambient & source artifact immunity – pressure, temperature… • Robust measurement Patented & Patents Pending

  11. Thermally de-coupling the optical sensor • Patented concept of thermally de-coupling optical path sight-tubes • Effective thermal de-coupling enables hi-temp measurement • Wide-band IR transmission • Gas filled for undisturbed transmission • De-focused optical system mitigating spot contamination on optics Patented & Patents Pending

  12. Patented Gas Flow Chamber • Vortex-flow chamber for undisturbed optical gas measurement • Structured gas flow for avoidance of residuals in optical path • Intrinsic cleaning effect on sight-glasses • Particles held away from optical path center-line Patented & Patents Pending

  13. Patented optical path protection • IR transmissive nano-coated sight-glasses • Contaminant repellent • Super hydrophobic • Heat & Corrosion resistant Patented & Patents Pending

  14. Combustion Emission Sensor System • Modular sensor system • Direct and continuous measurement • Hot/Wet combustion gasses • Configurable for exact gas measurement needs • All core technologies patented Patented & Patents Pending

  15. Future of emissions monitoring • The world depends on shipping, but emissions must be reduced • Global and local regulation will reduce emission • Multiple emissions mitigation technologies will be implemented • The operation of emissions mitigation systems should be optimized • The effect should be documented • Online emissions monitoring is part of efficient shipping
