2. The so-called waste engine oil means that the oil is mixed with impurities such as moisture, dust, other miscellaneous oil and metal powder produced by the wear of machine parts, which leads to black color and increased viscosity. The regeneration of waste engine oil is to remove impurities in engine oil by means of precipitation, distillation, acid washing, alkali washing and filtration. It is a toxic substance and a solid hazardous waste that is explicitly prohibited by the state. It is strictly forbidden to buy and sell waste engine oil at will, and it should be handled by qualified waste engine oil treatment enterprises.
3. Diesel oil is a mixture of light petroleum products and complex hydrocarbons (about 10 ~ 22 carbon atoms). Diesel fuel. It is mainly made from diesel oil fractions produced in crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes; It can also be made from shale oil processing and coal liquefaction. It is divided into light diesel oil (boiling point range is about 180 ~ 370℃) and heavy diesel oil (boiling point range is about 350 ~ 4 10℃). Widely used in large vehicles, railway locomotives and ships.
Question 2: Can waste engine oil and refined diesel really meet the standards? You can use it, but it depends on your skill. Their equipment is stupid, but the benefits are not high. Isn't it good to refine oil yourself? Is refining more profitable than selling equipment? With high technology, Youdan can purify-10#, with high technology and low oil content. Agricultural vehicles are almost ok, but carts that need to be added can also be used. I don't know your question, okay?
Question 3: Is it legal to extract diesel from waste engine oil? Please give up this idea. On the one hand, it pollutes the environment. On the other hand, it is not diesel at all. I have inspected this project and only extracted a liquid that can be used as fuel, not diesel. If it is used in a car, it is not good for the engine. If you have a lot of waste engine oil on hand, you can make concrete release agent, which can be used in construction sites, aerated block factories, cement component factories and so on. Mix waste engine oil and waste engine oil emulsifier OE- 100 water evenly to obtain the concrete release agent.
Question 4: Can I go through the formalities for refining diesel from waste engine oil? 1, Project of Planning Commission; 2. Environmental protection;
1. The extraction of diesel from waste oil needs environmental protection, which involves the generation of waste gas and the treatment of waste after high temperature treatment;
2, the plan is because the country has industrial restrictions; 3, safety supervision and fire protection can be considered, diesel is not dangerous goods, generally do not need safety supervision, but it is still flammable, so we should consider fire protection.
Question 5: How to refine diesel from waste engine oil? 1. Dehydration: after the waste engine oil is collected in the oil sump to remove water, it is put into an oil refining pot, heated to 70 ~ 80℃, then stopped heating, stood for about 24 hours, drained the surface water, and then slowly heated to 120℃ (when the oil temperature approaches 100℃, it should be heated slowly.
2. Pickling: After the oil is cooled to normal temperature, slowly add sulfuric acid (concentration is about 92-98%) under stirring, and the amount of acid added is generally 5-7% of the oil (depending on the pollution degree of the oil). After adding the acid, continue to stir for half an hour, then let it stand for about 12 hours, and discharge the acid residue.
3. Alkaline washing: reheat the engine oil after acid washing to 80℃, add soda ash (Na2CO3) while stirring, fully stir evenly, stand for 65438 0 hours, stand for more than 4 hours after the test paper is neutral, and discharge the alkali residue.
4. Activated clay adsorption: heat the oil to 120 ~ 140℃, add activated clay (its dosage is about 3.5% of the oil) under constant temperature stirring, and continue stirring for half an hour after adding activated clay, keeping the temperature at10 ~1.
5. Filtration: qualified oil can be obtained by filtering with an oil filter. If there is no oil filter, you can also use the method of hanging and filtering with cloth bags.
The above is the general operation flow of oil purification, but it depends on the actual situation. If there is little water containing impurities, the first step can be omitted; If the color of oil is normal after acid and alkali treatment, it is not necessary to decolorize and adsorb with activated clay.
Question 6: Is it illegal to open a waste oil refinery? There are many procedures, such as industrial and commercial tax, land, factory building, need in industrial zone, technical supervision, environmental protection and so on. Anyone who fails to meet the requirements will violate any relevant laws.
Moreover, the refined engine oil is not the previous engine oil, so it is impossible to use it as engine oil. If it is like refining diesel oil, it is actually just a flammable organic liquid, and its chemical composition is not diesel oil at all.
Therefore, it is not recommended that you take the risk of refining waste engine oil, which is characterized by high investment, high risk and low income.
If you have a lot of waste engine oil, you'd better make it into concrete release agent. Using "waste cooking oil emulsifier OE- 100" to mix waste cooking oil emulsifier with engine oil with the weight of 1-9 times, the cost is only a few cents per kilogram, and it can be sold for several yuan per kilogram. High profit and low risk. Find a shabby factory, process it in it, or stir it directly with an electric drill.
Question 7: Does the country allow the use of waste engine oil to refine diesel oil? Waste engine oil can only be regenerated after it has passed the qualification related to environmental protection and resource regeneration.
Question 8: The profit of refining diesel from waste engine oil is very high.
First of all, we must understand what engine oil is. Engine oil is usually called lubricating oil. Waste engine oil is the residual engine oil after long-term use and high-temperature lubrication. Lubricating oil itself is a by-product of atmospheric tower, and the fraction is heavy. After long-term high-temperature use in the engine, the fraction is heavier. If it is used as gasoline and diesel oil, it is easy to cause carbon accumulation in the engine cylinder and spark plug and damage the engine.
The key to processing engine oil into gasoline and diesel oil is to solve the following problems:
By cracking or coking, the fraction changes from heavy to light.
Influence of mechanical impurities on subsequent refining (mainly residues of metals and their oxide carbides)
Influence of additives in oil products on subsequent refining. These additives are compounds containing sulfur, phosphorus, nitrogen, chlorine, oxygen and a small amount of metal salts. If they are removed,
How to remove impurities such as small molecular oxides produced after oil deterioration?
When these are solved, it will be a big business. \r\n\r\n
Question 9: Can the oil extracted from waste engine oil and waste diesel oil meet the standard? Waste diesel oil and diesel oil produced after distillation can be used. However, the so-called refining of waste engine oil, waste plastics and waste tires is actually not diesel oil, but a combustible organic liquid. The chemical composition of this liquid is completely different from that of diesel oil, so it cannot be used as diesel oil for automobiles. However, it can be used as a flammable liquid. Even if it can be used as a flammable liquid, it will produce a lot of complicated and odorous gases when burning. This combustible liquid can be used in oil-fired boilers, but it can't be used.
