Background
Sulfur is a harmful substance in oil.,Sulfide of iron, ferric sulfate, sulfite, or sulfuric acid may easily form.,Severe corrosion of equipment. The combustion of gasoline also leads to significant environmental pollution, hence it is crucial to continuously reduce the sulfur concentration in fuel.
Chlorides are always present in oil, with concentrations varying greatly. Organic chlorines decompose during processing, leading to severe corrosion incidents throughout the refinery.EDXRFDetermining sulfur and chlorine levels in oil or fuel is one of the standard industrial analytical methods in modern times.
In China,2018.11.30The Ministry of Transport issued the "Implementation Plan for the Control Area of Ship Air Pollutant Emission," effective as of2022Year1Month1From the date on.,Vessels entering the coastal control area of Hainan waters should use fuel with sulfur content not exceeding0.1%m/mMarine Fuel 。
The new national V standard for automotive gasoline and diesel, as well as the VI standard, requires the allowable sulfur content to be less than10 ppm。
Introduction
Compass 4294 plusEnergy DispersiveXRay FluorescenceEDXRFWe offer a novel method for analyzing sulfur and chlorine content in petroleum products on-site, with a concentration range of2 ppmTo10Percentages vary.
