CMT has developed the OTK-CT-11218 Catalytic Fine Powder Test Kit

According to CMT, the advantages of the OTK-CT-11218 catalytic fine powder test kit include: electronic measurement and evaluation, no human error in visual interpretation; accuracy (+/- 2 ppm); catalytic fine powder limit required for pre-engine inspection It is 10 ppm; the inspection time for obtaining on-site inspection results is rapid (5 minutes); fuel oil can be delivered before and after the separator and before the engine; the performance of the separator can be checked.

All of the catalytic fines remaining in the fuel after centrifugation have the potential to cause engine wear and damage. Studies of high cylinder and piston ring wear cases have shown that catalyzing the intrusion of fine particles into the liner will cause nearly 90% wear, leading some engine manufacturers to limit the catalytic fines entering the engine to 10-15 ppm during combustion. That is the following. The maximum allowed by 60 ppm according to ISO 8217:2012.

The catalytic fine powder, which usually has an aluminum compound and a silicon compound, is small but heavy particles will be deposited in the oil tank sump over time. This deposition process will be facilitated by heat and vibration on the ship. Under severe climatic conditions, the catalyzed fines will be agitated by the sediment and will produce a very large amount of catalytic fines. Some shipping companies have reported that the catalyzed fines have reached several hundred ppm and more. And there are still ways to use the best methods to protect the engine from this potentially irreparable damage.

Although additional cleaning is required to handle high catalytic fines, additional cleaning is required to know the amount of catalytic fines. It is useful to measure the amount of catalytic fines removed by the separator and the amount of catalytic fines stored in the daily fuel tank after entering the engine to prevent potential damage.
