There are several key issues regarding waste lubricating oil recycling. If the following issues are resolved, your production will be very successful:

1. Yield issue: The yield should be above 80%, and a good one should be around 85%, so that you can get better benefits.

2. Slag removal problem: If your device cannot remove slag, you need to remove the slag every few days, which will waste a lot of manpower and financial resources, and then your device is unsuccessful.

3. Color and taste problems: If the color or taste of the products produced by your device is not good, the products will be difficult to sell or the price will be cheap.

4. Energy consumption problem: If the energy consumption of your device is too high (the cost is less than 500 yuan per ton excluding tax, including labor, water, electricity, chemical raw materials, etc., and some devices are 300-400 yuan per ton), then your device is not successful. Regardless of whether the technology is advanced or not, as long as the quality is qualified, the lower the energy consumption, the better. Hydrogenation technology is advanced, but it is not practical in my country’s national conditions.

5. Operational issues: I feel the simpler the better. Complex processes and too many valves will make it too difficult for operators and prone to errors.

In short, under the condition of meeting the quality requirements, the process should be simple, the energy consumption should be low, and the yield should be high. If your device meets the above points, congratulations. You will get rich soon.
