In diesel fuels, a portion of the sulfur content combines chemically with water during the combustion process to form sulfurous and sulfuric acid. The result is corrosive wear that eventually leads to component failure. TBN (Total Base Number) additives in the lubricant protect against high levels of sulfur content in fuel. It is important to know the sulfur content of the fuel because over-inhibiting with high TBN ... |
...lubricants will result in premature deposit formation. High TBN lubricants are more expensive as well.
The sulfur content in marine bunker fuels and off-highway diesel fuels can be determined using emission spectroscopy such as the Spectroil Q100. However, for quality control purposes, the quantity of sulfur to meet EPA requirements for ultra-low sulfur diesel fuel is usually determined by x-ray spectroscopy. |
