Water in diesel fuel

Вода в дизельном топливе

Water is an unacceptable admixture in diesel . According to GOST standards its presence in the is not provided. However, the reality is that water and its vapor in the domestic diesel are present. This happens mainly due to the method of hydrotreating of diesel aiming to eliminate sulfur impurities, hygroscopic properties of as well as violations of transportation and storage conditions. Condensation in the tank with diesel can occur in case of not fully loaded capacity. Tank vapor causing condensation of water is concentrating in the remaining empty space.

Bench tests have shown that traces of water in petroleum products in quantities up to 0,025% are acceptable for summer grades of diesel only, while such amount of water impurities for winter grades may lead to the formation of ice crystals and cause substantial damage to the mechanisms of diesel units. In practice, water content exceeds the norm significantly.

Water is considered to be the worst enemy of Diesel. Its presence in diesel can launch the growth of microorganisms and microalgae, which significantly reduce the quality of products and can clog filters and pump units. High pressure and injectors suffer from water in diesel internal combustion engines with Common Rail system. Due to the use of low-quality diesel there often occur cases of water hammer piston in diesel engines “atmospheric pressure”.

Current decisions available on the market including diesel fine filters that are being installed on modern vehicles are not fully effective due to the fact that they work mainly with the water separated from the primary emulsion into the sediment and do not work with the water dissolved in the . Also, the surface of these filters is quickly contaminated by mechanical impurities.

Laboratory of filtering materials “E-KO” offers its own accessible industrial solutions on purification of diesel from water at the molecular level, as well as mechanical and bacteriological contaminants at the stages of production, transportation and delivery of petroleum products to the final consumer.
