As an important chemical raw material and refrigerant, liquid ammonia is widely used in industrial production due to its efficient refrigeration performance and low cost. However, liquid ammonia has dangerous characteristics such as toxicity, flammability and explosion, and safety issues during its storage are crucial. Once accidents such as liquid ammonia leakage, fire explosion, poisoning and suffocation occur, it will not only pose a serious threat to the safety of personnel lives, but also cause huge economic losses to the environment and enterprises. Therefore, taking effective safety measures to ensure the safe storage of liquid ammonia is an issue that every company involved in liquid ammonia storage must pay attention to.
1. Choose suitable storage tank materials: Liquid ammonia storage tanks should be made of corrosion-resistant and high-strength materials, such as carbon steel or low-alloy steel. These materials can withstand the corrosiveness of liquid ammonia and have sufficient strength to withstand internal pressure. The materials of the storage tank should also comply with relevant national standards and industry specifications to ensure its quality and safety.
2. Design and manufacture of storage tanks: The design of storage tanks should be completed by qualified professional design units. The physical and chemical properties of liquid ammonia, storage capacity, use environment and other factors should be fully considered during the design process. The manufacture of storage tanks should be carried out strictly in accordance with the design drawings and relevant standards to ensure that key indicators such as welding quality and sealing performance meet the requirements. Storage tanks should be equipped with necessary safety accessories, such as safety valves, pressure gauges, liquid level gauges, etc. These accessories can monitor the pressure and liquid level of storage tanks in real time to ensure that the storage tanks operate in a safe state.
3. Regular inspection and maintenance: After the storage tank is put into use, it should be inspected and maintained regularly. The inspection content includes the appearance, anti-corrosion layer, welds, seals, etc. of the storage tank, and potential problems should be discovered and dealt with in a timely manner. Regularly perform pressure tests and leak detection on the storage tank to ensure the sealing and strength of the storage tank. For corrosion, deformation and other problems found, the relevant parts should be repaired or replaced in time.
1. Site selection and layout: Liquid ammonia storage area should be selected in a low-lying, well-ventilated place to avoid direct sunlight and high temperature environment. At the same time, it should be away from fire sources, heat sources and crowded areas. The storage area should have enough space for equipment installation, operation and maintenance, and obvious warning signs should be set up to remind personnel to pay attention to safety.
2. Fire and explosion prevention measures: The storage area should be equipped with sufficient fire-fighting facilities, such as fire extinguishers, fire hydrants, fire water cannons, etc. These facilities should be inspected and maintained regularly to ensure that they are available at any time. Set up fire dikes or cofferdams around the storage area to prevent liquid ammonia from leaking and spreading to other areas. The height and capacity of the fire dike should be designed according to the storage volume. Use explosion-proof electrical equipment and lighting facilities to avoid fire or explosion caused by electrical sparks. All electrical equipment should meet the explosion-proof grade requirements and be inspected and maintained regularly.
3. Ventilation and leakage detection: The storage area should be equipped with a good ventilation system to ensure air circulation and timely discharge of leaked ammonia. The design of the ventilation system should take into account the diffusion path of liquid ammonia after leakage to avoid ammonia accumulation. Install an ammonia leak detection alarm device to monitor the ammonia concentration in the storage area in real time. Once an ammonia leak is detected, the alarm device should immediately sound an alarm and start the ventilation system.
1. Operator training: Operators should receive professional training, including the physical and chemical properties of liquid ammonia, the operating procedures of storage equipment, emergency response methods, etc. Only those who have been trained and qualified can take up their posts. Operators should be regularly organized to conduct safety education and emergency drills to improve their safety awareness and emergency response capabilities.
2. Operating procedures and systems: Formulate strict operating procedures and safety management systems to clarify the responsibilities and operating steps of operators. During the operation, the operating procedures should be strictly followed to avoid illegal operations. Establish a safety management file for liquid ammonia storage, record the inspection, maintenance of equipment, operator training, etc., so that they can be checked and traced at any time.
3. Emergency response plan: Develop a detailed emergency response plan for liquid ammonia leakage, clarifying the emergency measures, personnel evacuation routes, fire-fighting measures, etc. when leakage occurs. The emergency response plan should be regularly rehearsed to ensure its effectiveness and operability. Stock up on sufficient emergency supplies, such as protective clothing, gas masks, plugging tools, etc., so that quick measures can be taken when a leak occurs.
In summary, the safety of liquid ammonia storage is extremely important, and effective safety measures need to be taken from equipment, environment, operation and other aspects. By selecting appropriate storage tank materials, designing a reasonable storage environment, and formulating strict operating procedures and emergency response plans, the safety risks in the liquid ammonia storage process can be effectively reduced. At the same time, strengthening the training and safety education of operators and improving their safety awareness and emergency response capabilities are also important guarantees for ensuring the safety of liquid ammonia storage.
