The oil layer also contains a certain amount of water, how to remove it

1. For solid impurities, such as sand or ants, filtration methods can be used. Find clean filter materials (filter cotton, filter gauze, etc., if you can't buy these special filter cloths, use clean towels, fabrics, etc.), find a funnel, and then fold the filter material into a funnel shape and put it into the funnel, and pour the oil mixed with impurities into the funnel. If the impurities are not completely removed after filtration, change the filter material and continue to filter, and repeat many times to remove the impurities.

2. Water mixed into the oil can easily cause the grease to smell, so after the oil enters the water, the water should be removed. For a small amount of water, you can use the method of heating and evaporating water to remove, pour the oil into the hot pot, it is best to use a pot that can control the temperature, it is recommended to control the temperature of the pot at about 100 degrees Celsius, stirring while heating, the oil with moisture will bubble in the hot pan, and heat until the oil does not bubble, you can completely remove the water.

3. For the case of mixing more water, you can use desiccant to absorb water, and after the desiccant absorbs water, then remove the desiccant by filtration, and may also participate in the trace water, and then remove it by heating. Generally, quicklime granules desiccant can be used. The desiccant dehydration process goes like this::

Sprinkle the quicklime powder desiccant into the mixed oil, stir while slowly sprinkling, add until the quicklime particles are no longer dissolved, stir fully for about half an hour, and then put the oil in a cool and dry place to stand and precipitate for about 12 hours, and finally pour out the upper clarified oil layer for filtration and trace water removal.

4. For the oil mixed with water-soluble impurities such as mud and dust, if the impurities cannot be filtered out, the dust can be removed by water treatment. Pour more water into the oil (the amount of water added is more than double the oil), and then use a spoon and other tools to stir constantly, it is recommended to stir for about half an hour, the specific time can be decided, and then put the oil in a cool and dry place to stand for about 12 hours, and then pour out the clarified part of the upper layer, and finally remove the water.

Magnetic double-sided granular demulsifier for heavy oil water removal.

Heavy oil is the remaining heavy oil after extracting gasoline and diesel, which is characterized by large molecular weight and high viscosity. The specific gravity of heavy oil is generally in the calorific value of 10,000 to 11,000 kcal kg. Its composition is mainly hydrocarbons, but also contains some sulfur and trace amounts of inorganic compounds.

Heavy oil, also known as fuel oil, is a dark black liquid, according to the classification method of international conventions, heavy oil is called durable oil, as the name suggests, this oil is relatively viscous and difficult to volatile. So once ashore, it's hard to remove. It is mainly blended with atmospheric oil, vacuum residue, cracking residue, cracking diesel and catalytic diesel in the processing process.

The heavy oil with its specific gravity exceeds that of heavy oil, which has a high viscosity, contains a large amount of nitrogen, sulfur, wax and metal, and basically does not flow, while tar sand cannot flow. In mining, some need to inject heat into the ground, such as injecting steam, hot water, or some hydrocarbons to dissolve it and increase its fluidity, while others use methods similar to coal mining.
