95 Ethanol Manufacturing Method

1. Introduction

Ethanol, also known as alcohol, is an organic compound widely used in chemical, pharmaceutical, food and other fields. Among them, 95 ethanol has unique value in many applications due to its specific concentration and properties. This article will detail the manufacturing method of 95 ethanol.

2. raw materials and equipment

1. raw materials: the main raw materials for starch or sugar substances, such as corn, potato, molasses and so on.
2. Equipment: fermentation tank, distillation tower, condenser, storage tank, etc.

3. manufacturing steps

1. starch saccharification: first, starch raw materials after pretreatment, adding saccharifying enzyme for saccharification, starch into fermentable sugar.
2. Fermentation: The saccharified sugar liquid is cooled to a suitable temperature, and then fermented by yeast to convert the sugar into ethanol and carbon dioxide.
3. Distillation: After the fermentation, the fermentation liquid is sent to a distillation column for distillation to separate a mixture of ethanol and water.
4. Rectification: A mixture of ethanol and water is separated by rectification to obtain ethanol with a concentration of 95%.

4. precautions

1. In the process of operation, we should strictly control the temperature, pH and other parameters to ensure the growth of yeast and the fermentation process.
2. During the distillation process, the distillation speed and tower pressure should be controlled to avoid poor separation of ethanol and water.
3. In the distillation process, the operating parameters should be adjusted in time according to the changes of temperature and pressure in the tower to ensure product quality.

5. Conclusion

Through the above steps, we can successfully produce 95 ethanol. However, it should be noted that the manufacturing process must strictly abide by the safety procedures to ensure the smooth progress of the production process. At the same time, in order to better improve the yield and quality of ethanol, further research and optimization of manufacturing processes are needed.

6. prospects and recommendations

With the continuous progress of science and technology, ethanol manufacturing methods will continue to improve and optimize. In the future, we can explore the use of new biotechnology, catalysts and other means to improve the production efficiency and quality of ethanol. In addition, we should also pay attention to the environmental protection and sustainable development in the ethanol production process, take effective measures to reduce energy consumption and waste emissions, and realize green production.

In order to better promote the development of 95 ethanol manufacturing technology, we recommend:

1. Strengthen technological research and development and innovation: invest more resources in technological research and development and innovation to improve the technological level and competitiveness of ethanol manufacturing.
2. Promote new technologies and equipment: Actively promote the application of new technologies and equipment in ethanol manufacturing to improve production efficiency and quality.
3. Strengthen production supervision and safety management: establish and improve production supervision and safety management systems to ensure the smooth progress of the production process and the safety and health of employees.

In short, the continuous improvement and optimization of 95 ethanol manufacturing methods will help increase the yield and quality of ethanol, and provide more high-quality raw materials for the development of chemical, pharmaceutical, and food fields.
