Knowledge of waste oil purification and regeneration equipment

Presumably, many friends nowadays want to know more about the knowledge of waste oil purification and regeneration equipment. So today, I have collected some knowledge about this and shared it with you. I hope you will like it.

Technical steps for purifying waste engine oil:

(1) By adding a special catalyst to the waste oil raw material and conducting catalytic cracking at medium temperature, both waste oil and various mineral oil products can achieve cracking effects:

(2) The gas components obtained after cracking are further catalytic cracked in a fixed bed to obtain oil vapor:

(3) Oil vapor is fractionated and gasoline and diesel fractions are collected separately:

(4) Gasoline and diesel fractions are refined separately.

The entire process not only ensures product quality through the removal of impurities, but also simplifies equipment investment, reduces volume, and shortens production cycle.

The obtained oil has good quality, high transparency, and can achieve the same effect as mineral water. It has low carbon content and belongs to unleaded gasoline, which can meet the national standard of 93 # gasoline.

The yield is high, and the total amount of oil obtained is over 90% of the weight of waste oil.

After use, engine oil is mixed with various impurities such as water, organic matter, pigments, and dust, and is often discarded

Waste oil purification and regeneration equipment

Lubricating oil itself is not an energy source, but it is a product extracted from petroleum. Therefore, the reasonable recycling and reuse of waste lubricating oil is essentially energy conservation. Another important significance of waste lubricating oil recycling and regeneration is to protect the environment and reduce atmospheric and soil pollution

In 2011, the actual consumption of lubricating oil in China was 7.1 million tons, with approximately 3.5 million tons of waste lubricating oil

According to predictions, the annual production of waste lubricating oil will continue to rise, surpassing the United States to become the world's largest by 2020

90-95% of waste lubricating oil can be recycled, processed, and reused, and can be reused repeatedly

Especially 70% of it can be processed into lubricating oil base oil, which has a significant resource saving effect on the production of base oil with low crude oil extraction rate.

The regeneration principle is based on the principle that oil and water are insoluble and the boiling point of water is lower than that of engine oil. Water can be removed by heating and static separation.

By utilizing the oxidizing properties of concentrated H2SO4 to remove organic matter, using activated clay to adsorb pigments, and filtering to remove mechanical impurities, the purpose of engine oil regeneration can be achieved.

What is the process flow of waste oil refining equipment?

1. Firstly, the collected waste engine oil is injected into the distillation kettle of the diesel oil refining equipment. The waste engine oil is boiled and gasified through the heat transfer oil heating system and fuel heating system. Impurities in the waste engine oil continuously settle during the heating process, and the remaining oil and gas enter the condensation system after being catalyzed by the catalyst

2. Let the oil and gas pass through a double-layer catalytic tower. The reactants in the catalytic tower can remove the gum and wax in the oil and gas generated from waste engine oil. After degumming and dewaxing, the oil will become clearer

3. After catalytic reaction, the oil and gas enter the condensation system, and the oil and gas are liquefied into diesel oil through the circulating cooling water in the condensation system and enter the temporary storage tank

4. Introduce the diesel refined from the waste engine oil refining equipment into the decolorization system, resulting in a clearer and brighter color of the diesel after decolorization

5. The gas that cannot be liquefied first passes through the water seal system, and then is transported to the heating chamber for full combustion through a dedicated gas nozzle

6. For the smoke and dust emitted from fuel combustion, the waste oil refining diesel equipment has specially designed a desulfurization, dust removal and purification system. After treatment, the smoke emitted is white smoke (mainly water vapor and carbon dioxide), which can meet the national emission standards

What filtration equipment is needed to extract diesel from waste engine oil?

With the development of the times and the progress of the country, the increasing scarcity of energy and the increasing environmental requirements, energy regeneration has gradually been valued, considered and planned by the country and government.

In such a situation, the waste oil industry has rapidly become popular, with many enterprises and individuals competing to build lines, install equipment, and change processes to start recycling, refining, and production of waste oil.

At present, there are two common types of waste oil in the market. The first type refers to the mixture of water, dust, other miscellaneous oil, and metal powder generated by machine wear during use. The second type refers to the gradual deterioration of engine oil over time, resulting in the formation of organic acids, resins, and asphalt like substances

The regeneration of waste engine oil refers to the removal of impurities from the engine oil through methods such as sedimentation, distillation, acid washing, alkali washing, filtration, etc., in order to be reused

Regenerated waste engine oil is generally used as a raw material for producing diesel and lubricating oil. Waste engine oil that has undergone sedimentation, distillation, acid washing, and alkali refining usually needs to undergo the process of adding white earth for decolorization before being converted into diesel and lubricating oil. The traditional old-fashioned filtration methods generally use two methods: decolorization sand filtration and plate frame filtration. These two methods were still accepted by workers before the 1980s, but with the progress of the times, The improvement of workers' demands has resulted in the inability of these two filtration methods to meet the requirements in terms of efficiency, ease of operation, and labor intensity. In order to meet the development of the times and the needs of customers, oil decolorization filters have been applied. This equipment combines the filtration principle of traditional plate and frame filters, integrates the requirements and opinions of customers, introduces Dutch technology, and develops the equipment: oil decolorization filters have simple operation and small footprint, Fully enclosed filtration, pollution-free to materials, mechanical vibration for slag removal, reducing labor intensity of workers. Each filter mesh is equipped with five layers of stainless steel mesh, which is sturdy and durable. The filter mesh can be used for many years without frequent replacement of filter cloth and paper, reducing filtration costs. It is the preferred equipment in the filtration industry

I want to buy a set of waste oil refining equipment and make it myself

The following is for reference only

This article introduces an improved small-scale oil refining system that aims to eliminate pollution, produce high-quality products, achieve higher production efficiency, achieve higher economic benefits, and enhance market competitiveness

Waste oil purification and regeneration equipment

1、 Social production requires excellent small-scale oil refining There are two different methods for processing waste oil, and millions of vehicles are constantly flowing. Each vehicle needs regular maintenance and oil change.

Waste engine oil is constantly produced year after year, month after month.

Waste oil purification and regeneration equipment

If it becomes environmental pollution, it is many times more serious than the waste plastic called white pollution: it cannot be processed.

Although many waste engine oils can be regenerated into base oils through acid-base refining, not all waste engine oils can be regenerated

For example, waste engine oil, which contains detergents and dispersants, does not completely precipitate acid residue and is currently difficult to regenerate

Large refineries can only use large quantities of raw materials with consistent composition

Waste engine oil is produced in scattered locations, with variable components and relatively small quantities: it cannot be added to atmospheric heavy oil as a raw material for the vacuum tower of a large refinery

Cracking requires reaction time and requires intermittent feeding

So the only way to process waste engine oil is through intermittent small-scale refining

There are also many oil materials that need to be processed using intermittent small-scale refining methods, such as floor oil in oil fields, bottom oil sludge in large tanks, intermediate substandard oil in large refineries, and tank cleaning oil.

Waste mineral oil generated by other industries includes waste solvent oil: mixed oil produced by local refining, and so on.

They are not suitable for adding to large quantities of raw materials.

The oil components in these oils need to be cracked into diesel and gasoline, and the mixed diesel and gasoline must be separated from each other through fractionation to become qualified products

Like waste plastic

Waste plastics with a single variety can be granulated and recycled to produce recycled plastics

But the waste plastic components generated in paper mills or household waste treatment are mixed, intertwined, and messy, making it difficult to sort: it can only be refined

One ton of waste plastic replaces one ton of waste oil for oil refining, valued at 5000 yuan

Currently, everyone is quite interested in waste oil purification and regeneration equipment, and everyone wants to learn more. Therefore, the editor has also collected some relevant knowledge online for everyone to read.
