Due to high temperature and air oxidation, the engine oil may produce a variety of oxides. Friction between engine parts can produce metal powder, respiration can produce moisture, these substances into the oil, and the oil will eventually lead to the color of the use of the process gradually blackening, reducing the viscosity. Sediment, such as sludge, can be created during the use of the engine. These impurities can damage the oil film, corrode the metal parts, and cause wear and tear on the equipment. And eventually clog the governing system, causing damage to the equipment. So the users must change the engine oil frequently and selecting a Solvent Extraction Machine is necessary.

How to Change the Waste Engine Oil?

Now that the drivers want to change the engine oil, a question comes out. How to change the waste engine oil? There are several steps to follow. The first step is preparing some necessary tools. The drivers need to prepare seven kinds of tools. The oil filter wrench, oil drain pan, funnel, latex gloves, jack, and jack stands or ramps. The second step is checking the type and amount of the engine oil because the engine oil can be separated into several kinds of oil. The drivers need to make sure of the kinds of engine oil. The third step is to prepare the vehicle and locate the oil filter and drain plug. The fourth step is to drain the oil and tighten the drain plug. The fifth step is to change the oil filter and add new engine oil. By the way, do not forget to check the engine oil level. The oil level should not be too high or too low. Oil must be added in strict accordance with the specifications of the car.

The Methods to Treat the Waste Engine Oil with Solvent Extraction Technology

So what should we do with the collected waste oil? Some people will choose to bury waste oil, others will choose to burn waste oil. These two methods are indeed the way to deal with waste oil, but they are not the best way. Because burning or burying waste oil will cause great damage to the environment, this method is not advisable. The best choice is to use a machine to refine waste oil. The waste oil treated by the solvent refining machine will get clean base oil. This not only protects the environment but also saves the cost of oil.

The waste oil recycling technology and process based on the solvent extraction process are simple in operation, low in energy consumption, good in quality of reclaimed oil, and can eliminate the pollution of acid residue. Therefore, according to the actual development level of domestic waste oil regeneration, with environmental protection and energy-saving, low cost, improve the quality of the recovered oil as a starting point, combining solvent extraction technology and flocculation sedimentation technology to be recycled waste oil extraction – flocculation technology, based on existing research results to improve optimization of the solvent refining technique is the development trend of the waste oil regeneration industry at the present stage in China.

The types of solvent extraction are divided into liquid-liquid extraction and solid-phase extraction. The solvent extraction equipment which is produced by Yangjiang has the features of filtration capacity up to 10 microns, organic removal up to 2 ppm, 660 GPM, 2,000 GPM & 3,300 GPM flow rate, custom controllers, vessel internals, matrix plates, valves & pressure vessels. 

The Working Principle of Solvent Extraction Plant

 The principle of a solvent recycling machine is to take advantage of some organic solvents in the waste lubricating oil containing hydrocarbons and additives, oxidation products, sludge, and other solubility different characteristics, under certain conditions, the waste oil additives, oxidation products, sludge, and other impurities removed, and then distillation recovery solvent. This device can be used oil decompression hair oil, cutting line oil, black wood, machine oil, waste liquid pressure oil, transformer oil, and other waste containing no solid particles oil one-time processed into performance close to the second type of base oil, hydrogenated oil chroma water white, color code below 0.1, viscosity, viscosity index, acid value, carbon residue, demulsification, pour point, saturated hydrocarbon and other indicators are at or near the level of 2 kinds of hydrogenated base oil. If it is used together with the distillation unit produced by our company, the refining effect will be better.

Treatment Flow of Solvent Extraction Machine

• Preheating part: the raw oil is preheated to the working temperature in the preheated tank with stirring.
• Pre-treatment part: the preheated raw oil and working medium enter into the displacement device of the pre-treatment part at the same time. Through the special working principle of the displacement device, most of the sulfide, oxide, nitride, colloid, asphalt, aromatic hydrocarbon, and unsaturated hydrocarbon in the raw oil is absorbed by the working medium. Separated from the working medium, the oil enters the next stage of deep treatment.
• Working medium recovery in the former treatment: the working medium is processed by the recovery module to separate the adsorbed components and form residual oil into the slag tank. Working medium shall be kept for recycling within the former treatment part (new working medium e and old working medium e shall be recycled for new working medium).
• Advanced treatment part: the semi-finished oil processed by the former treatment part is sent into the advanced treatment module together with the working medium. The working medium adsorbs trace impurities remaining in the semi-finished oil, and at the same time absorbs a small amount of working medium from the previous treatment, and the oil separated from the working medium enters the filtration part. The working medium of the section 
• Depth of processing recycling: working medium through recycling, adsorption of small amounts of impurities and working medium, the precipitation in the mixture into the front-end processing part working medium recycling processing module for recycling, working medium after regeneration recycling (new medium old working medium recovery working medium).
• Filtering: after dealing with the depth of oil, the filter oil machine, oil interception or entrained in trace solids, enhance oil cleanliness, then into the finished product tank.
