The continuous distillation unit stands as a pinnacle of efficiency and productivity in the field of chemical engineering. This advanced apparatus serves the purpose of separating liquid mixtures into their respective components through the process of distillation, with a continuous and uninterrupted operation.
Unlike batch distillation, which is performed in discrete batches, the continuous distillation unit allows for a constant supply of feedstock and removal of product streams simultaneously. This design significantly improves the production capacity and reduces the overall time required for distillation processes.
One of the key advantages of the continuous distillation unit is its ability to handle high volumes of liquid mixtures efficiently. The continuous feed of the mixture and the simultaneous withdrawal of distilled products ensure a steady flow and optimal utilization of resources. This makes it a preferred choice in industries such as petrochemicals, pharmaceuticals, and food processing where large-scale production is essential.
The continuous distillation unit consists of a series of interconnected chambers, including the feed chamber, distillation columns, and condensers. The feedstock enters the unit through the feed chamber, where it is heated to vaporize the volatile components. The vapor then rises through the distillation columns, which are packed with various stages of trays or structured packing materials that facilitate separation based on differences in boiling points.
As the vapor ascends in the distillation columns, it undergoes repeated stages of condensation and vaporization, allowing for the separation of different components based on their boiling points. The condensed products collect in the trays or flow down the structured packing, while the non-condensable gases are removed through vents or reflux streams. The final products can be collected and further processed or used directly in various applications.
The continuous distillation unit offers multiple advantages over alternative separation techniques. Its continuous operation ensures a consistent and high-quality product output, reducing the need for additional purification steps. It also minimizes energy consumption by utilizing heat exchangers to provide reflux and preheat the feed, optimizing the overall process efficiency.
Additionally, the continuous distillation unit allows for better control and fine-tuning of the separation process. It enables adjustments in factors such as temperature, pressure, and feed rates to achieve desired separation efficiency and product compositions.
In conclusion, the continuous distillation unit plays a crucial role in the chemical industry, offering a highly efficient and continuous method for separating liquid mixtures. Its ability to handle large volumes, precise control, and optimized energy consumption make it an indispensable tool for a wide range of industries. With the continuous distillation unit, chemical engineers can achieve optimal separation and purification, enabling the production of high-quality products on a large scale.

Thin-film distillation and short-path distillation are two commonly used separation techniques that are widely used in the separation of volatile components of silicone oils and resins. This article will explain in detail the principles and applications of these two technologies and their application in the separation of volatile components of silicone oil and resin.


Abstract: Oil deacidification is an important step in food processing, which aims to remove free fatty acids in oil and improve its quality and stability. Traditional deacidification methods have some limitations, such as low efficiency, high energy consumption, and loss of nutrients. In recent years, molecular distillation technology has gradually attracted attention as a new deacidification method. This article will introduce the application of molecular distillation in oil deacidification, including the principle, operation process and advantages, and focus on the outstanding advantages of Aishengke in molecular distillation technology.


Vitamins are products that are closely related to people's lives, and have become one of the main bulk products in the international pharmaceutical and health care products market. The amount of vitamin E is the largest, followed by vitamin A, vitamin C, vitamin D and so on. With the growth of economy and the improvement of people's living standards, the demand for vitamin products will further increase, and people's requirements for their quality and grade will also further increase. Therefore, as an important separation technology in the production of many vitamins, molecular Distillation technology will also play an increasingly important role in the vitamin industry.


Glyceryl monostearate (GMS), abbreviated as monoglyceride, is produced from natural vegetable oils and fats. The active ingredient is purified by molecular distillation technology to more than 90%, also known as molecular distillation monoglyceride. It is the most widely used food Additives, safe to use in the production and processing of food, medicine, plastics, etc., account for more than half of the emulsifier consumption in the market.


The principle of molecular distillation is to make use of the different degrees of affinity between different molecules. By controlling the conditions such as temperature and pressure, the mixture begins to vaporize. Different components in the vapor form liquids in the condenser and are separated according to their boiling points. This distillation method not only has a good separation effect, but also can be repeatedly separated and purified, and is widely used in chemical, pharmaceutical and other fields.


Molecular distillation is a common chemical method used to separate and purify compounds. In the pharmaceutical industry, molecular distillation is widely used in pharmaceutical purification. This article will focus on the application of molecular distillation in pharmaceutical purification and provide some specific examples.


Laboratory vacuum distillation equipment has undergone significant advancements in recent years, driven by the need for higher efficiency, improved safety, and enhanced user experience.
