Ethanol in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

Ethanol as a common organic chemical raw materials, widely used in medicine, food, energy and other fields. However, due to its flammable and volatile characteristics, ethanol has certain safety risks during storage and transportation. In order to ensure production safety and reduce the probability of accidents, it is very important to formulate strict ethanol storage and transportation regulations.

2. the physical and chemical properties of ethanol

ethanol is a colorless, transparent, flammable, volatile liquid with alcohol taste. Its molecular formula is C2H5OH and its molecular weight is 46.07. The melting point of ethanol is -114.1 ℃, the boiling point is 78.37 ℃, the flash point is 12.78 ℃ (closed cup), the spontaneous ignition point is 423 ℃, and the explosion limit is 3.3-19%. In addition, ethanol has certain toxicity, and long-term exposure or inhalation of ethanol vapor may cause damage to the human nervous system and liver.

3. ethanol storage specification

1. storage facilities: ethanol should be stored in a dedicated storage tank or sealed container, storage tank should be equipped with lightning protection, anti-static, anti-spark and other safety facilities. The storage area should be dry, well ventilated, and away from fire and heat sources.
2. Storage limit: In order to ensure safety, the storage of ethanol should be strictly controlled within the specified range to avoid safety hazards caused by excessive storage.
3. Storage identification: obvious safety identification and warning signs shall be set up in the storage area, including flammable, toxic, no fireworks and other identification.

4. ethanol transport specification

1. transport vehicles: ethanol transport should use special dangerous goods transport vehicles, vehicles should be equipped with fire prevention, anti-static, anti-leakage and other safety facilities.
2. Transport personnel: Transport personnel should be professionally trained, familiar with the nature of ethanol and safe operation procedures, and have the ability to respond to emergencies.
3. Transportation route: The transportation route should be smooth and smooth, and avoid driving in sensitive areas such as densely populated areas and near important facilities.

5. ethanol safety operation specification

1. Operators should be professionally trained to understand the nature of ethanol and safe operation procedures, with the ability to respond to emergencies.
2. During the operation, the safety operation procedures should be strictly observed, fireworks are prohibited, and electrostatic sparks should be avoided.
3. During the operation, the equipment should be regularly inspected and maintained to ensure that the equipment is in good working condition.

6. emergency measures

1. In the process of storage and transportation, in case of ethanol leakage, fire and other emergencies, the emergency plan should be started immediately, and personnel should be organized for rescue and disposal.
2. Professional emergency rescue team and emergency rescue equipment shall be equipped to ensure timely and effective disposal in case of emergencies.

7. conclusion

ethanol, as a common organic chemical raw material, has certain safety risks in the process of storage and transportation. In order to ensure production safety and reduce the probability of accidents, it is very important to formulate strict ethanol storage and transportation regulations. By complying with the standard storage, transportation and safe operation requirements, the safety risk of ethanol in the production process can be reduced and the smooth progress of the production process can be guaranteed.
