Method of manufacturing 95 ethanol
I. INTRODUCTION
Ethanol, also known as alcohol, is an organic compound widely used in the fields of chemicals, pharmaceuticals and food. Among them, 95 ethanol is uniquely valuable in many applications due to its specific concentration and properties. In this article, the manufacturing method of 95 ethanol will be described in detail.
2. Raw materials and equipment
1. Raw materials: the main raw materials are starch or sugar substances, such as corn, potatoes, waste molasses and so on.
2. Equipment: fermenter, distillation tower, condenser, storage tank, etc.
3. Manufacturing steps
1. Starch saccharification: firstly, the starchy raw material is pretreated and then saccharification is carried out by adding saccharification enzyme to convert starch into fermentable sugar.
2. Fermentation: The saccharified sugar solution is cooled down to a suitable temperature and accessed to yeast for fermentation to convert sugar into ethanol and carbon dioxide.
3. Distillation: At the end of fermentation, the fermentation broth is sent to a distillation column for distillation to separate the mixture of ethanol and water.
4. Distillation: By means of distillation, the mixture of ethanol and water is separated, and the final 95% concentration of ethanol is obtained.
4. Precautions
1. During operation, parameters such as temperature and pH should be strictly controlled 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. During the distillation process, the operating parameters should be adjusted in time according to the changes of temperature and pressure in the tower to ensure the product quality.
V. Conclusion
Through the above steps, we can successfully manufacture 95 ethanol. However, it should be noted that the manufacturing process should strictly comply with the safety operation regulations to ensure the smooth progress of the production process. Meanwhile, in order to better improve the yield and quality of ethanol, further research and optimization of the manufacturing process are needed.
VI. Prospects and Suggestions
With the continuous progress of science and technology, the manufacturing methods of ethanol will be improved and optimized. 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 environmental protection and sustainable development in the ethanol production process, and take effective measures to reduce energy consumption and waste emissions to realize green production.
In order to better promote the development of manufacturing technology for 95 ethanol, we suggest:
1. Strengthening technological R&D and innovation: invest more resources in technological R&D and innovation to improve the technological level and competitiveness of ethanol manufacturing.
2. Promote new technologies and equipments: Actively promote the application of new technologies and equipments in ethanol manufacturing to improve production efficiency and quality.
3. Strengthen production supervision and safety management: establish and improve production supervision and safety management system to ensure smooth production process and employees' safety and health.
All in all, the continuous improvement and optimization of the manufacturing methods of 95 ethanol will help to improve the yield and quality of ethanol, and provide more high-quality raw materials for the development of chemical industry, medicine, food and other fields.
