RESEARCH INTO CHANGES IN CONCENTRATION OF IMPURITY METALS IN THE COMPOSITION OF SEMI-PRODUCTS DERIVED FROM PROCESSING OF “AVERAGED” OIL

The aim of the research was to study features distribution impurity metals in distillates several types heavy oil produced Uzbekistan, mixed with gas condensate. It has been revealed that basic mass impurities original is represented mainly by calcium salts petroleum acids. Thermal decomposition metal naphthenates accompanied formation highly corrosive organic concentration organometallic compounds V, Ni, Fe and other d-elements oils Uzbekistan comparatively less than known deposits Middle East Russia. However, corrosion activity acids, together presence hydrogen sulfide reaction medium, causes a sharp increase feedstock supplied hydrotreating, form mixture FeO(OH), FeO, Fe2O3 , Fe0 1-хS, FeS CaS. proven for producing environmentally friendly commercial fuels oils, as well ensuring long-term operation catalysts hydrotreating distillate residual fractions obtained processing local hydrocarbon raw materials, it recommendable use special protective layers actively extract products, along such calcium, nickel iron.
