Emission Monitoring – why?
Main drivers: Energy optimisation
Environmental soundness
Meeting regulations
CO2NO - NO2 - PM
CO - H2O – SO2
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

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
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
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
