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


    Monitoring Technologies – Schematic

    Visualization& Reporting

    Gas sampling at stack

    Experience gained cld
    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


    Experience gained zro2
    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

    Future of emissions monitoring
    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
