Description
The new AD System ST10 is an automatic, portable instrument for on-site analysis of fuel stability.
ST10 is a full automation of the ASTM D4740 method, which carries out sample preparation and results analysis.
Bulk fuel stored for long periods can become unstable the asphaltene content can precipitate out of solution causing the formation of sludge. This has the potential to block filters and pipes, leaving tanks with an unpumpable residue.
The 'break up' is dependent on the nature of the liquid hydrocarbons in which the asphaltenes are suspended. Once a fuel has chemically broken down there is no way to satisfactorily reverse the process. Precipitated asphaltene cannot be re-dissolved.
Issues surrounding fuel stability and compatibility have never been more relevant, especially with the new 0.10 per cent sulphur level for fuels used in Emission Control Areas (ECAs)
