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

1. Introduction

Ethylene oxide is an important organic chemical raw materials, widely used in the production of ethylene glycol, ether, ethanolamine, acetic acid and other chemical products. However, ethylene oxide is toxic and flammable, and requires extremely high safety for storage and transportation. In order to ensure safety in the production process, the storage and transportation regulations of ethylene oxide must be strictly observed.

2. the physical and chemical properties of ethylene oxide

ethylene oxide is a colorless and transparent liquid with a pungent odor. Its boiling point is 10.4 ℃, flash point is -17.8 ℃, spontaneous combustion point is 429 ℃, very volatile and combustion. Ethylene oxide is sensitive to water and air and can react with a variety of substances, so special care is required during storage and transportation.

3. the safety of ethylene oxide storage specifications

1. Storage facilities: ethylene oxide should be stored in a cool, ventilated, dry special warehouse, away from fire, heat and direct sunlight. The warehouse floor should be anti-skid, anti-static, and equipped with corresponding fire fighting equipment.
2. Storage container: Ethylene oxide should be stored in a special stainless steel or carbon steel container, and the container should be well sealed to prevent leakage. It is forbidden to use plastic, glass and other non-corrosion resistant containers for storage.
3. Storage capacity: The storage capacity shall be controlled within a safe range and shall not exceed the maximum allowable storage capacity of the warehouse. At the same time, the ventilation and fire fighting facilities of the warehouse should be checked regularly to ensure safety and reliability.

4. the safety of ethylene oxide transport specification

1. transport vehicles: ethylene oxide should be transported by a dedicated tank truck, and the vehicle should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. During transportation, the vehicle speed should be kept stable, and sudden braking and sharp turns should be avoided.
2. transport personnel: transport personnel should be professionally trained, familiar with the nature of ethylene oxide and safety procedures. Anti-static work clothes and protective gloves shall be worn during transportation. Smoking and open fire are prohibited.
3. Transportation route: The transportation route should be smooth and smooth, and avoid passing through densely populated areas and sensitive areas as far as possible. At the same time, it is necessary to communicate and coordinate with the local government and relevant departments to ensure the safety during transportation.

5. ethylene oxide leakage emergency treatment specification

1. leakage treatment: once found ethylene oxide leakage, should immediately start the emergency treatment plan, take measures such as cutting off the leakage source, ventilation and exhaust, dilution and diffusion, to prevent the accident from expanding.
2. Personnel evacuation: in case of leakage accident, nearby personnel should be evacuated immediately, and warning line should be set up to prohibit irrelevant personnel from entering the accident site.
3. Medical treatment: For those who are exposed to ethylene oxide, they should be immediately sent to the hospital for treatment to avoid delaying the condition.

6. summary

ethylene oxide as an important chemical raw material, its safety and stability is of great significance for chemical production. In the process of storage and transportation, it is necessary to strictly abide by relevant regulations, strengthen safety management, and ensure the safety of personnel and the environment. At the same time, it is necessary to establish and improve the emergency treatment mechanism. Once a leakage accident occurs, measures can be taken quickly to minimize the loss and impact.
