Manufacturing Method of Industrial Alcohol
I. Introduction
Industrial alcohol is a kind of important chemical widely used in the fields of chemical industry, medicine, energy and so on, and its main component is ethanol. This paper will introduce the manufacturing method of industrial alcohol, including raw material selection, process flow, equipment selection and other aspects.
II, raw material selection
industrial alcohol manufacturing raw materials are mainly starchy raw materials, molasses raw materials and sulfite wood pulp waste liquid. Among them, starchy raw materials such as corn, sorghum, potatoes, etc., are commonly used raw materials in China. After these raw materials are treated by fermentation, distillation and other processes, industrial alcohol with high ethanol content can be obtained.
3. Process flow
The manufacturing process of industrial alcohol mainly includes the following steps:
1. Raw material treatment: the selected raw materials are crushed, pasted, etc., so that they are easy for the subsequent fermentation process.
2. Fermentation: Under the action of yeast, the starch or sugar in the raw material is converted into ethanol and carbon dioxide.
3. distillation: heating the fermentation broth to the boiling point of ethanol to separate the ethanol vapors from the fermentation broth and obtain crude alcohol.
4. Distillation: The crude alcohol is distilled for several times to separate the impurities with different boiling points and get the industrial alcohol with higher purity.
4. Equipment Selection
In the manufacturing process of industrial alcohol, the following equipment is needed:
1. Crusher: used to crush the raw materials into a suitable size for fermentation.
2. paste pot: used to paste the crushed raw materials.
3. Fermentation Tanks: Used for the alcoholic fermentation process and need to have the functions of heat preservation and aeration.
4. Distillation Tower: Used to distill the ethanol from the fermentation solution to obtain crude alcohol.
5. Distillation tower: used for distillation of crude alcohol to get higher purity industrial alcohol.
5. Precautions
In the manufacturing process of industrial alcohol, the following matters need to be paid attention to:
1. Control the temperature and pH value in the fermentation process to ensure the growth of yeast and fermentation effect.
2. During distillation and rectification, parameters such as temperature and pressure need to be controlled to ensure the quality and purity of the product.
3. Regular maintenance and servicing of the equipment is carried out to ensure proper operation and service life of the equipment.
VI.Conclusion
The manufacturing method of industrial alcohol involves several process steps and equipment selection, which need to be selected and adjusted according to the specific situation. At the same time, attention needs to be paid to controlling the parameters and indicators in the manufacturing process to ensure the quality and purity of the product. Through scientific and reasonable manufacturing process and equipment selection, high quality industrial alcohol can be produced to provide important raw material support for chemical, pharmaceutical, energy and other fields.
