High level processing of oil slime wastes
into diesel oil and asphaltic road oils is a
perfect solution for the environment
protection

Recyclable
Oil slime from waste water settling ponds of
the oil refinery plant
Emulsified oil and bituminiferous
slimes of oil-and-gas production
department and drilling department
Oil slimes from clean-up of oil-pipe lines and
tanks
Oil slimes from clean-up of
tankers
Wastes of emulsols, cutting oils, steel-
hardening oils of factories
Oil slimes from steaming stations of
Ministry of Railways
Oils and fuel waste of transport companies
Oil waste of metallurgical production
3
Environmental problems as a result of hydrocarbon pollution
• Oil contaminated waste accumulating on the surface poison environment and disturb ecology
• Spilled crude oil and refined products is an economic waste and threat to the environment and population health
SOLUTION• Funding for oil slimes cellars and waste water settling ponds
decommissioning can ONLY be obtained by processing hydrocarbons, extracted from oil slimes, to highly valuable products
4
Goals for creating Oil slimes processing facility
• Complex solution for crude oil and refined products pollution-related ecological problems of the region
• Return of lost hydrocarbon materials to the commercialization
• Bio-remediation of oil-contaminated soil and water on the basis of self-financing (by income from oil slimes processing)
5
Systematic approach solution is requiredwaste disposal => recycling
problem => solutionpartial solutions => system solutions
Internal consistency of partial solutions complex
• availability of flexible technology (set of technologies)
• raw material efficient logistics
• hydrocarbon processing high profitability
• waste-free processing, no secondary pollution
With consideration for external conditions
• variety of oil slimes
• raw materials resources distribution
• planned unprofitability of ecological rehabilitation
• support of state and local government

Used technology features
• Technology of extraction and initial processing of oil slimes using solvents, heating and cavitation and acoustic actions can intensify extraction process and oil slime purification, and provide year-round works
• It is IMPOSSIBLE to get oil concentrate suitable for the further high-level and efficient processing using conventional method of extraction and purification
9
Used technology features
Technology provides production of oil slime materials:
• Lean oil with content of petrol and diesel oil cut more than 70%,or
• Overhead products: up to 15% petrol components up to 55% diesel oil cut
• Residual products: 30% fuel oil М100,or 20% unoxidized bitumen (road/construction types)
10
Lean oil characteristics
• Density at 20°С 0,85-0,88 g/cm3
• Pour point -10 ÷ +10 °С
• Water content < 0,5% mass.
• Solids content < 0,5% mass.
• Initial boiling point 30-40°С
• Boils up to 350°С 65-70% vol.
