[Chemical Knowledge]：Propane storage and transport specifications

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

1. Introduction

propane is a common chemical production raw materials, widely used in fuel, refrigeration, chemical and other fields. However, due to its flammable and explosive characteristics, there are certain safety risks in the storage and transportation of propane. In order to ensure production safety and reduce the probability of accidents, it is very important to formulate safe storage and transportation specifications for propane.

2. the physical and chemical properties of propane

propane is a colorless, odorless, flammable gas with a chemical formula of C3H8. Its boiling point is -42.1 ℃, critical temperature is 96.8 ℃, and critical pressure is 4.25MPa. Propane is insoluble in water, but it can form an explosive mixture when mixed with air, which can cause combustion and explosion when exposed to open flame and high heat.

3. propane safety storage specification

1. Storage facilities should be located reasonably, away from fire and heat sources, and have good ventilation conditions. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.
2. The storage facilities shall have sufficient bearing capacity and solid structure to prevent accidents caused by propane leakage. Storage containers shall comply with relevant standards and be regularly inspected and maintained.
3. Special storage tank shall be used for propane storage, and the tank shall be provided with monitoring equipment such as level gauge, thermometer and pressure gauge, so as to timely understand the status of propane in the tank.
4. During the storage process, the temperature, pressure and liquid level of propane should be strictly controlled to avoid overpressure, overtemperature, overloading and other phenomena.
5. The storage area shall be provided with combustible gas alarm device to detect and deal with propane leakage accident in time.

4. safety transportation specification

1. The transportation of propane should comply with the requirements of relevant laws, regulations and standards, using special transportation vehicles or ships, and equipped with corresponding fire-fighting equipment and protective equipment.
2. Before transportation, the safety performance of transportation vehicles or ships should be checked to ensure that they can maintain stability during transportation and prevent propane leakage accidents due to bumps, collisions and other reasons.
3. In the process of transportation, the temperature, pressure and liquid level of propane should be strictly controlled to avoid overpressure, overtemperature, overloading and other phenomena. At the same time, the state of transport vehicles or ships should be checked regularly to ensure their safety and reliability.
4. During transportation, traffic rules should be observed, the speed of the vehicle should be kept stable, and operations such as sudden braking and sharp turns should be avoided to reduce safety risks during transportation.
5. In the process of transportation, combustible gas alarm device should be set to detect and deal with propane leakage accident in time. At the same time, should be equipped with professional escort personnel to ensure the safety of the transport process.

for emergency treatment of propane leakage accident in
5.
1. In case of propane leakage accident, the emergency plan shall be started immediately and professionals shall be organized to deal with it. At the same time, people nearby should be evacuated quickly and a cordon should be set up to prevent irrelevant personnel from entering the scene of the accident.
2. For a small amount of propane leakage, it can be treated by spraying water mist or using inert gas dilution. For a large number of propane leakage, professional recovery equipment should be used for treatment to avoid the harm of propane diffusion to the environment.
3. When dealing with propane leakage accidents, attention should be paid to the use of explosion-proof tools and equipment to avoid sparks causing explosion accidents. At the same time, site ventilation should be strengthened to reduce propane concentration and reduce explosion risk.

6. conclusion

propane as a common chemical raw material, its safe storage and transportation is very important. In the actual production process, we should strictly abide by the relevant norms and standards, strengthen the training of management and operation personnel, improve safety awareness and skill level, and ensure the safe and reliable storage and transportation of propane.
