The oil regenerated from the waste engine oil is too thin, what should I do? Urgently

Recycled engine oil cannot be used in automobiles, so it is recommended to use special engine oil for automobiles.

We are very happy to answer for you, dear, waste engine oil to be cleaned and regenerated generally has to go through the following five steps; 1.Water removal: After collecting the waste engine oil to the oil collection tank to remove the water, put it in the oil refining pot, stop heating after heating to 70 80, let it stand for about 24 hours, drain the surface of the open water, and then slowly heat up to 120 (when the oil temperature is close to 100, it should be heated slowly to prevent the oil from boiling and overflowing), so that the water evaporates, after about two hours, the oil does not turn, and the black oil and gas can come out of the oil surface.

2.Pickling: After the oil is cooled to room temperature, slowly add sulfuric acid (concentration is about 92 98) under stirring, and the acid dosage is generally 5 7 of the oil amount (depending on the degree of oil pollution).

After adding the acid, continue to stir for half an hour, and then let it stand for about 12 hours to drain the acid residue. 3.Caustic washing:

Reheat the pickled oil to 80, add soda ash (Na2CO3) under stirring, stir well, let it stand for 1 hour, and then test it with a test strip to be neutral, and then let it stand for more than 4 hours to drain the alkali residue. 4.Activated clay adsorption:

Raise the oil to 120 140, add activated clay at constant temperature and stirring (the amount is about 3 5 of the amount of oil), after adding the activated clay, continue to stir for half an hour, stand at a constant temperature of 110 120 overnight, and filter while hot the next day. 5.Filtering:

It can be filtered by an oil purifier, and qualified engine oil can be obtained after filtration. If there is no oil filter, the bag hanging filter method can also be used. The above is the general operation process of purifying used engine oil.

Waste engine oil is generally poured into a large barrel, and then add an appropriate amount of thinner, such as kerosene or diesel, and then heat and stir for a while, so that the thinner penetrates into the oil, so that the dirt, impurities and other substances in it are suspended in the diluent, and with precipitation, the oil itself is gradually clear. Finally, after filtering through a strainer, you can get clear engine oil for reuse. Of course, there are no skills and safety precautions that need to be mastered in this process, so don't try it at home, it's best to hand it over to a professional oil company for processing.

Summary. Hello, your question is how about water in aircraft oil? not to precipitate.

First, after the oil and water are thoroughly stirred, it will produce a milky engine oil, which contains water.

Second, after a period of precipitation, the oil and water will produce a certain degree of separation, so the oil and water can not be 100% completely integrated, and the oil will cause the color of the oil to become milky white after being mixed with water.

The above is the information for you, and I hope it can help you.

How to mix water in waste engine oil so as not to precipitate?

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, your question is how about water in aircraft oil? First, after the oil and water are fully stirred, there will be milky oil, which contains water Second, after a period of precipitation, the oil and water will produce a certain degree of grid, so the oil and water can not be 100% completely integrated, and the oil will cause the color of the oil to become milky white after being mixed with water, the above is to provide you with information, I hope to help you.

At present, there is no good technology and method that can be directly reduced, and there are generally two ways to dispose of waste engine oil:

First, it is converted into non-standard diesel through catalytic cracking and high-temperature distillation;

The second is to stir with activated clay through acid and alkali washing, heating, and then use a filter to beat out the oil. This method is more common in Jiangsu and Zhejiang.

Because the second method must be acid-alkali washing and heating, it is easy to affect the oil, so now some people have begun to use decolorization sand to directly filter and decolorize, this method has higher requirements for oil products, and the speed is relatively slow.

You can choose these ways according to your needs.

The first is the distillation and extraction clay process, which uses ethanol for extraction.

Solvent; The other is the high-temperature clay process, which is distilled with clay.

Fraction, furfural also has a better extraction effect than ethanol, and the base oil is recovered.

Rate. Longyuan New Energy Company's technology is that the waste engine oil is filtered through the wire mesh to filter mechanical impurities, and then through nature.

Sedimentation removes water impurities, and the oil is sent in after pre-distillation of clay.

The tubular distillation combined refining unit is heated and refined by circulation, and injected into the furnace tube.

Water vapor. It is then obtained through a series of processes such as furfural extraction.

Recycled oil. This process is followed by vacuum distillation followed by a falling film to decompress.

The yield is 7% 9%.

1. Find a new bottle;

2. Register a trademark called "good engine oil" brand engine oil;

3. Fill in waste engine oil;

As a result, used engine oil becomes good engine oil.

Mainly according to the hydraulic oil, mechanical oil and other lubricating oil impurity characteristics of special development and production, the machine has a short processing cycle, high efficiency, can quickly remove water, gas, impurities and volatiles (alcohol, gasoline, ammonia, etc.) in the oil. Improve the quality of the oil, restore the viscosity, flash point and performance of the lubricating oil. It is used in the purification of hydraulic oil, hydraulic transmission shaft, gear oil, gasoline engine oil, diesel engine oil, compressor oil, refrigeration engine oil, heat treatment oil, etc.

It can quickly remove water, gas and mechanical impurities in the oil, flash evaporate to remove light acid and light moisture, improve the quality of the oil, and restore the performance of the lubricating oil. Ensure the normal operation of power, hydraulics and lubrication systems.

This can generally be restored after refining by a small refinery.

But the quality is generally not very good!! This is commonly referred to as inferior motor oil!

Heated and boiled, but it is also a fake and inferior engine oil, but the color is good-looking!

Waste engine oil and processing method thereof.

The petroleum molecule is made up of carbon chains. The atmospheric fractions are arranged by molecular size as non-condensable, gasoline, kerosene, and diesel. Lubricating oil is a vacuum fraction, and there are no less than 100 varieties according to the viscosity, use and additives.

Most of them are various engine oils. The carbon number of one engine oil molecule is about equivalent to two or three diesel, four or five gasoline, and a dozen non-condensable. The lubricating oil is constantly oxidized and deteriorated during use, forming viscous gum and asphaltene; It can also be mixed with mechanical impurities and moisture.

Generally, when the deterioration part reaches 5 10%, it can no longer be used and is scrapped, becoming what people call waste engine oil.

Some repair points or pour oil ** into the oil with water, pay attention to quality inspection when purchasing.

Many used engine oils can be refined at room temperature by acid and alkali to remove the spoiled part, a process called regeneration. Additives are often removed when sulfuric acid and gum, asphaltene and mechanical impurities form acid residues, so the recycled product is not a lubricant but a base oil. The base oil is originally blended with a vacuum fraction and has a certain viscosity, which becomes a lubricating oil after adding additives.

A lot of used motor oil can be regenerated. However, not all used motor oil can be restored and regenerated. The engine waste engine oil contains a cleaning and dispersing agent, and after the acid residue is generated, the agglomeration and precipitation are incomplete due to the dispersion effect, and cannot be completely removed; Regeneration doesn't work.

The only way is to heat the waste engine oil to crack, and the heating and cracking require reaction time and have to stay in the refinery kettle. The diesel and gasoline produced by cracking need to be separated in the fractionation column and the products can be obtained separately in order to be qualified. This is how batch refining is processed.

There are often sporadic leftovers in the oil field that cannot be added to the bulk product. Such as floor oil, single well oil, tank bottom sludge and so on. These include non-condensable gas, gasoline, kerosene, diesel, heavy oil (i.e., vacuum fractions) and other ingredients, which are mixed together and are nothing at all.

Only by cracking heavy oil through oil refining to produce diesel gasoline, so that diesel and gasoline and other components are separated in the fractionation column, can each become a qualified product. There are also oil fields or large oil refineries, which are sludge dissolved in gasoline and diesel; Waste solvent oil in the paint industry is dissolved into waste paint, and they must be separated by fractionation.

I would like to express my high respect and absolute spiritual support for the spirit of LZ's contribution to all mankind!!

In addition, I am deeply impressed by SF's professionalism!!
