Subject(s): Online resources: Summary: Black Carbon (BC) is a climate and health problematic emission, caused by the combustion of fossil fuels in, e.g., the shipping industry. Efficient monitoring of the emissions is a first step towards reducing this harmful pollution. This report describes the development and testing of Green Instruments EMS BC sensor technology using the Extinction Minus Scattering (EMS) method to quantify the BC concentration in engine exhaust. The EMS BC sensor is an online and in-situ measurement technique that has several advantages compared to the traditional extractive techniques as well as filter deposition methods, such as Filter Smoke Number (FSN) or Photoacoustic spectroscopy (PAS). The priorities in the development activities were to ensure that the measurement system has low maintenance, sufficient robustness, appropriate accuracy, and validity, and is relatively easy to install on various exhaust and ship types. The system has been evaluated on test engine exhaust, followed by sea trial both as in-situ and extractive editions of the EMS BC.Summary: Black Carbon (BC eller sod) er en klima- og sundhedsproblematisk udledning, forårsaget af forbrænding af fossile brændsler i fx skibsfarten. Effektiv overvågning af emissionerne er det første skridt mod en reduktion af denne skadelige forurening.1 Denne rapport beskriver udviklingen og testen af en Green Instruments EMS BC-sensor teknologi ved hjælp af EMS-metoden (Extinction Minus Scattering) til at kvantificere BC-koncentrationen i motorens udstødning. EMS BC-sensoren er en online og in-situ måleteknik, som har flere fordele sammenlignet med de traditionelle ekstraktionsteknikker samt filteraflejringsmetoder, såsom Filter Smoke Number (FSN) eller Photoacoustic spectroscopy (PAS).2 Prioriteterne i udviklingsaktiviteterne var at sikre, at målesystemet har lav vedligeholdelse, tilstrækkelig robusthed, passende nøjagtighed og validitet og er relativt let at installere på forskellige udstødnings- og skibstyper. Systemet er blevet evalueret på testmotorens udstødning, efterfulgt af test på skibe både som in-situ- og ekstraktionsudgaver af EMS BC.
