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

1. Introduction

Ethylene is an important chemical production of raw materials, widely used in plastics, synthetic rubber, synthetic fibers and other fields. However, ethylene is also a flammable, explosive and toxic gas, which requires high safety for storage and transportation. In order to ensure the safety of ethylene during production, use and transportation, it is important to establish strict storage and transportation regulations.

2. the physical and chemical properties of ethylene

ethylene is a colorless, odorless, flammable gas with a low boiling point and high vapor pressure. It can form an explosive mixture in the air, which can cause combustion or explosion when exposed to fire or high heat. In addition, ethylene also has an anesthetic effect and has a certain toxicity to the human body.

3. Ethylene Storage Specifications

1. Storage facilities: Ethylene should be stored in a special steel container, which should comply with relevant safety standards, and be inspected and maintained regularly. Storage facilities should be located in a well-ventilated area away from fire and heat sources.
2. Storage limit: In order to ensure safety, the storage of ethylene should be strictly controlled and must not exceed the specified maximum storage.
3. Safety identification: Obvious safety identification shall be set near the storage facilities, including warning signs such as flammable and toxic.

4. ethylene transport specification

1. transport vehicles: ethylene should be used for special tanker transport, vehicles should meet the relevant safety standards, and equipped with the corresponding fire equipment and protective equipment.
2. Transportation route: The transportation route should be smooth and smooth, and avoid passing through densely populated areas and important facilities.
3. Transport personnel: Transport personnel should be professionally trained to understand the nature of ethylene and safe operation procedures, and have the ability to respond to emergencies.

5. ethylene safety procedures

1 in the operation of ethylene, should wear protective clothing and protective gloves, to avoid direct contact with ethylene gas.
2. Obvious safety signs shall be set up in the operation area, and smoking and open fire operation shall be prohibited.
3. During the operation, good ventilation should be maintained to avoid the accumulation of ethylene gas in the confined space.
4. During the operation, the equipment and pipelines should be checked regularly for air leakage. If air leakage is found, it should be handled in time.

6. emergency measures

1. In case of leakage during storage and transportation, the emergency plan shall be started immediately, personnel shall be evacuated and effective measures shall be taken for disposal.
2. In case of fire or explosion accident, the fire alarm telephone shall be called immediately and the emergency plan shall be activated to organize personnel to carry out fire fighting and rescue work.

7. conclusion

ethylene is an important raw material for chemical production, and its safe storage and transportation are very important. In order to ensure the safety of ethylene during production, use and transportation, strict storage and transportation specifications should be formulated, and safety training and emergency drills for operators should be strengthened to improve the ability to respond to emergencies.
