Distillation is a type of technology that can separate or purify substances of a liquid mixture. The equipment used for distillation is generally known as distillation apparatus kit, which is mainly composed of three parts: a distillation flask, a condenser and a receiving flask.
What Equipment is Used in Distillation?
The short-path distillation is regarded as a typical distillation apparatus kit. It is a technique that removes solvents form mixtures through evaporation, which is mainly used for liquid-liquid separation. The principle is that the pressure difference between the boiling film and condensing surface is the driving force of the steam flow, and the minimum pressure will cause the flowing of steam. It is one of the most high-efficiency distillation techniques in people’s using, which can solve the problem that conventional distillation technology can’t. It is widely used in food, medicine, fine chemicals, electronic materials, plastic engineering and polymers (such as polyols, fatty acids, polyphenols, polyurethane, epoxy resins, lactic acid, monoglycerides, flavors, heavy oils and paraffin oils) and other fields.
What are the Two Basic Methods of Distillation?
Simple Distillation and Fractional Distillation are two basic methods of distillation. Fractional Distillation is often used to separate components with small boiling point differences, while simple distillation is usually used to separate components with large boiling point difference as well as separate liquids from solid impurities. They have different pros and cons. Fractional Distillation can purify liquids containing several different components better even though there are small boiling point differences. But it requires more energy, slower and more complex than Simple Distillation. So on the other hand, Simple Distillation is faster and simpler, requiring less energy. But it can only be used for the separation of relatively pure liquids and there should be a large boiling point differences between components.
Distillation Apparatus Kit
Making distillate is quite widely used in industrial field. People extract substances and purify compounds through distillation. In lab, people always have one professional distillation apparatus kit for making distillate, which includes:
- Evaporation flask: where sample get heated and extracted solvents get evaporated into gas, is the key apparatus in the whole distillation equipment
- Receiving flask: which extracted solvents go into after being turned into liquid solvents and users use it to collect extracted solvents
- Chiller: a device used to cool the whole distillation equipment down and turn extracted gas solvents into liquid solvents
- Vacuum pump: a device used to create vacuum environment for the whole distillation equipment and prevent extracted solvents being contaminated, which is very essential for the whole process
- Condenser: which is connected with chiller to be the condensing part of the whole distillation equipment
- Glass tubes: which is to transfer the extracted gas solvents
Alcohol Distillation Kit
Alcohol distillation equipment is a device used to extract ethanol directly from the rectified beer which has less energy, water, manpower. In the whole equipment of alcohol distillation kit, there are several parts in it. For example, the beer column is the main reacting venue for extracting ethanol from mash. Alcohol distillation column improve the purity of ethanol (spirit) by it’s closed heating. Distillation column of final purification reduces the content of methanol. Methanol distillation column removes end impurities from rectification column. Distillation column of impurity concentration concentrates the head and upper intermediate impurities in order to release the alcohol from overhead. In the process of producing alcohol, water is supplied in order to improve the yield of impurities in hydro-selection column.
