Concise description
Marine vessel exhaust has to correspond to more and more rigid exhaust regulations. Our customers can profit from SICK’s experience with diesel power plants for the emission measurement of vessel engines.
Task
As in all combustion processes, high concentrations of sulfur dioxide and nitrogen oxides are emitted into the atmosphere during operation; for marine vessels the high concentrations are caused by the use of cheap fuel often extremely rich in sulfur. To minimize the pollution of the environment, very strict emission limits have to be observed. The IMO (International Maritime Organization) initiated directives for the avoidance and control of air pollution which were published in the "MARPOL Annex VI" and the "revised NOx technical code 2008". The exhaust allowed for SO2 and NOx will be gradually reduced. The exhaust must have the same concentrations as that of a low-polluting fuel. Motor producers try to reduce nitric oxide emissions by modifying the motors. The NOx limits required after 2016 however, can only be met by using waste gas cleaning systems. Norwegian Cruise Line installed as a pioneer emission monitoring on the Norwegian Epic. SICK provided the measurement solution.
Implementation
The focus is on measurement precision and reliability
Approved and low-maintenance measurement technique is in demand. The MCS100E HW analyzing system accomplishes exactly this: precisely and reliably it measures SO2 and NOx and can even be upgraded for the measurement of further gas components. From the sampling unit to the cuvette, all ducts having contact with measuring gas are heated over the dew point and thus protected against corrosion. Additionally the system offers two further advantages: the measurement of water to enable calculations at standard conditions and the check of CO limits to optimize the combustion process. The MCS100E HW is equipped with an automatic unit for calibration point control. This saves time and expensive calibration gases which are only needed for the annual or semi-annual maintenance check.
Only vessels able to prove they observe the limits, will in future be allowed to pass into emission control areas. Therefore they have to depend on reliable, low-maintenance analyzing systems, because on the ocean and during short stays in harbors, service technicians are not easy to get hold of.
Customer benefits
Approved allround experience in emission measurement
SICK offers a suitable solution for every application.
| The MCS100E HW has been measuring successfully for decades in coal and diesel power plants. You can profit from this experience - also for the emission monitoring of vessel fuels |
| After 2016 at the very latest, the limits for NOx measurements will be so small that you will be lost without a catalytic exhaust cleaning system. Catalyzers in power plants are already controlled by the MCS100E HW, as well as the injection of NH3 or urea |
| The exhaust cleaning plants to remove SO2 from the exhaust flow can be monitored and controlled by the MCS |
| The MCS100E HW usually measures a single gas flow, but can also switch between different exhaust channels. This can be done automatically or manually, making the MCS100E HW a reliable device with low life cycle costs |
