1. Tower diameter and tower height: The tower diameter and tower height determine the capacity and processing capacity of the distillation tower.
2. Packing: The type and specification of packing used in distillation columns have a significant impact on separation efficiency. Common fillers include stainless steel θ ring fillers, ceramic Rascal ring fillers, glass spring fillers, and stainless steel triangular fillers.
3. Heating and cooling system: including heating power, insulation section heating power, temperature control mode, etc. 
4. Temperature control: including the number and range of temperature controllers, temperature errors, etc. 
5. Vacuum degree: The highest vacuum degree can reach 60Pa (about 0.05mmHg), suitable for distillation processes that require low-pressure operation.

6. Liquid flowmeter and pressure gauge: The range of liquid flowmeter and pressure gauge, for example, the range of liquid flowmeter is 1.6-16ml/min, and the range of pressure gauge is -0.1-0.1MPa.
7. Reflux ratio controller: used to control the reflux ratio of the condensed liquid at the top of the tower, for example, the control range of the swing reflux ratio controller is 99:1 to 1:99.
8. Control system: including operation panel, display, adjustment and control functions, facilitating users to set and adjust various parameters.
9. Material: The material of the distillation tower has a significant impact on its durability and applicability.
