[Chemical Knowledge]：Specification for storage and transportation of liquid ammonia

1. of safety storage and transportation specifications
of liquid ammonia in the field of chemical production raw materials Introduction

As an important chemical production raw material, liquid ammonia is widely used in the production of chemical products such as fertilizers, nitric acid, soda ash and other chemical products. However, due to its toxicity, corrosiveness, flammability and explosion, there are great safety risks in the storage and transportation of liquid ammonia. In order to ensure the safe storage and transportation of liquid ammonia, it is essential to formulate standardized storage and transportation specifications.

2. the nature and harm of liquid ammonia

1. Toxicity: liquid ammonia on the human body has a strong irritation, can cause respiratory tract, skin and eye irritation and damage, prolonged exposure to high concentrations of ammonia may lead to poisoning.
2. Corrosion: Liquid ammonia is corrosive to metal and non-metal materials and may cause damage to equipment, pipes and containers.
3. Flammable and explosive: After liquid ammonia is mixed with air, it may explode under certain conditions.

3. safety of liquid ammonia storage specification

1. Storage facilities: liquid ammonia should be stored in a dedicated storage tank, the storage tank should meet the relevant standards, with good sealing and corrosion resistance. Cofferdam shall be set up in the storage tank area to prevent liquid ammonia from spreading after leakage.
2. Storage environment: The liquid ammonia storage area should be dry and well ventilated, away from open flames, heat sources and direct sunlight. The storage temperature should be controlled within a suitable range to avoid the impact of too high or too low temperature on the equipment.
3. Storage capacity control: The storage capacity of liquid ammonia should be controlled within a safe range and should not exceed the upper limit of the storage tank. At the same time, the safety inspection and maintenance of the storage tank should be carried out regularly to ensure the normal operation of the equipment.
4. Safety management: We should establish and improve the safety management system of liquid ammonia storage, strengthen staff training and improve safety awareness. At the same time, emergency plans should be formulated and drills should be conducted regularly to deal with emergencies.

4. safety of liquid ammonia transport specification

1. transport vehicles: liquid ammonia should be used for transport tank cars, vehicles should meet the relevant standards, with good sealing and corrosion resistance. At the same time, the vehicle should be regularly inspected and maintained to ensure the normal operation of the equipment.
2. Transport personnel: liquid ammonia transport personnel should have relevant qualifications and experience, professional training, understand the nature and hazards of liquid ammonia, master the safety operation procedures. In the process of transportation, we should be vigilant, find and deal with abnormal situations in time.
3. Transportation route: safe transportation route should be selected for liquid ammonia transportation, avoiding passing through densely populated areas, important facilities and other sensitive areas. At the same time, you should know the road conditions and weather conditions in advance to ensure the safety of the transportation process.
4. Transportation documents: The transportation of liquid ammonia should carry relevant safety documents and transportation certificates so that they can be presented during inspection on the way.
Emergency treatment
for
5. liquid ammonia leakage
1. Personnel evacuation: In case of liquid ammonia leakage, the emergency plan should be started immediately to evacuate the personnel near the leakage area, and a safety warning line should be set up to prohibit irrelevant personnel from entering.
2. Leakage treatment: According to the specific situation of liquid ammonia leakage, appropriate measures should be taken to deal with the leakage, such as the use of special equipment to absorb and recover the leaked liquid ammonia to prevent its spread from causing harm to the environment.
3. Medical treatment: For those who are exposed to high concentrations of ammonia, they should be sent to the hospital for treatment immediately to avoid the occurrence of poisoning symptoms.

6. conclusion

the safe storage and transportation of liquid ammonia in the field of chemical production raw materials is very important, and it is necessary to strictly abide by the relevant norms and standards to ensure the normal operation of equipment and the safety of operators. At the same time, we should strengthen the formulation and exercise of emergency plans, improve the ability to deal with emergencies, and ensure the safety of people's lives and property.
