RESEARCH TO IMPROVE THE METHODOLOGY FOR DETERMINING THE SULFUR CONTENT IN DIESEL FUEL

The introduction of new technical regulations and stricter environmental standards for gasoline and diesel fuel imply the use of high-precision methods of monitoring their properties. One of the main controlled indicators is the content of sulfur in the fuel. Sulfur in diesel fuel is one of the negative elements in its content. The permitted amount of sulfur-containing impurities is strictly limited, since their presence negatively affects the environmental situation and reduces the life of the equipment. The article presents the method of lamps for determining sulfur in diesel fuel, describes the apparatus for determining sulfur in petroleum products. The value of the lamp method according to the known GOST consists in burning the oil products in a glass lamp and absorbing the resulting sulfur dioxide with a solution of sodium carbonate and oxidizing the resulting sodium sulfite with oxygen to sodium sulfate. Application of the proposed modified method in practice will help to prevent errors in the determination of sulfur in petroleum products. The value of the method consists in burning a sample of oil with a wick in a glass lamp and absorbing the resulting sulfur dioxide with a solution of iodine.
