Project Construction Background
Waste oil belongs to ‘900-249-08 waste mineral oil produced in other process of production,selling and application’ in ‘National Hazardous Waste List’. Waste mineral oil refers to the waste lubricating oil that has been replaced, lost or lowered function after use of mechanical equipment in the industrial production field and transportation equipment such as automobiles and ships.
China’s waste mineral oil recycling industry began to develop in the 1960s, but the technology is backward and quality is inferior. In the late 1980s,waste mineral oil recycling industry began to develop rapidly,especially since 2000,waste mineral oil recycling enterprises’ scale and technology has improved greatly and quality is also largely improved.But,currently there are still many illegal oil refining factories nationwide who purchase waste mineral oil at high price in the market,crack down inferior gasoline and diesel through simply processing,pollute the environment badly and evade taxes.
One. Policy Background
On December 10th,2011, the National Development and Reform Commission issued the ‘Notice on printing and distributing the ‘Twelfth Five-Year’ Resources Comprehensive Utilization Guidance and the implementation plan for the comprehensive utilization of bulk solid wastes’. The notice pointed out that key industries should be encouraged to carry out recycling and resource utilization of used motor oil, oil production waste water, waste plant oil, waste acid, waste alkali, waste liquid. Waste motor oil recycling and resource utilization is the key industries that encourage development.
Two. Market Background
In recent years, the number of Chinese privacy cars is growing at a rapid rate. It is estimated that by 2020, the number of Chinese civilian vehicles will reach 140 million.Together with various vehicles, China’s ultimate car ownership will reach 250 million.
With the development of Chinese automobile industry and the increase of car ownership, more and more waste motor oil has been replaced from automobiles. So, finding an effective and low investment way to recycle the waste motor oil has not only good social benefit but also good economic benefits. Especially in today’s high oil prices, it is worthwhile for us to find and consider various recycling measures.
Three. Technology Background
In the composition of waste lubricating oil, besides 2% to 3% waste water, some waste impurities and some metamorphic materials(waste mineral oil is only about 10% to 25% of the hydrocarbons deteriorated compared with before scrapping, most of the rest hydrocarbon composition is still the main viscosity carrier of the lubricating oil. ) 90% to 98% of the rest are good components and can be completely reused. Choosing a reasonable process, specializing in the recycling of waste lubricating oil,can solve a series of problems such as difficulties in dehydration and impurities removal, difficulty in fractionation of waste lubricating oil, and a large processing unit cost.
After removing deteriorated substances and impurities in waste lubricating oil, it can be recycled to lubricating base oil that meets the quality requirement. And the recovery rate can reach more than 70%.
