FIELD: oil-and-gas production.
SUBSTANCE: invention related to method of diesel fuel refinery and aimed to increase quality of a typical and off-quality fuel by decontamination it out from harmful impurities. Invention consists diesel fuel decontamination method, which includes dosed mixing of row fuel with water, solution cavity treatment and its separation on the fuel and deposits and water in a precipitation tank, before dosed mixing with a row fuel water to be saturated with iron ions till solution get yellow-brown colour with pH>6, solution cavity treatment executed by supersonic sound during its CO2 barbotage with temperature 75-80°C and overburden relatively to solution pressure >0.2 gatm, after that solution treated with light photons with energy 60-70 kkal/mole, passed through magnetic field and forwarded to tank.
EFFECT: invention is also related to diesel fuel decontamination equipment.
