Distillation is a common treatment method in the waste oil treatment process. However, foam generation is a common problem during the waste oil distillation process. To this end, we can choose to add an appropriate amount of waste oil distillation defoamer to better protect the service life and resource environment of the equipment. Well, useWaste oil distillation defoamerHow can it help? Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
1. The reason for the distillation and foaming of waste oil
1.Waste oil composition is complex:Waste oil contains a variety of surfactants, which are prone to foaming during the distillation process.
2.Temperature and pressure fluctuations:Fluctuations in temperature and pressure during the distillation process can trigger the formation of foam.
3.Gases are constantly mixed in:Gas mixing during waste oil distillation can also lead to the formation of foam.
Second, the harm of waste oil distillation and foaming
A large amount of foam will occupy the volume of the distillation column, reduce the heat transfer efficiency, thereby affecting the distillation efficiency, resulting in the liquid level being too high, causing an impact on the distillation equipment and affecting the life of the equipment; In addition, excessive foam can lead to a decrease in oil quality, affecting subsequent processing and reuse, and may also affect operator safety and increase the risk of accidents.
3. The help of defoamer in waste oil distillation
On the one hand, the waste oil distillation defoamer can quickly eliminate the formed foam, inhibit the regeneration of foam, improve the heat transfer efficiency, thereby improving the distillation efficiency, reducing the liquid level and reducing the impact on the distillation equipment, and prolonging the service life of the equipment. On the other hand, the use of waste oil distillation defoamers also helps to improve the quality of the oil, providing better raw materials for subsequent processing and reuse, while reducing safety risks and improving operator safety.
