The Difference Between Liquid Ammonia Cylinders and Liquid Ammonia Storage Tanks
Liquid ammonia cylinders and liquid ammonia storage tanks are very different in terms of function, capacity, structure, etc. Liquid ammonia cylinders are usually used for small-scale storage and transportation of liquid ammonia, while liquid ammonia storage tanks are used for large-scale storage and transportation of liquid ammonia. The volume of liquid ammonia cylinders is usually between 40L and 50L, while the volume of liquid ammonia storage tanks is more than 20m³. Liquid ammonia cylinders have a simple structure and are easy to transport, while liquid ammonia storage tanks have a more complex structure and require professional installation and maintenance.
How Long can Liquid Ammonia be Stored in Cylinders?
Liquid ammonia should be stored in a cylinder with good sealing performance, and then stored in a cool and ventilated environment without sunlight. If possible, it is best to store it in a warehouse below 20 degrees Celsius. As long as the liquid ammonia (ammonia gas) does not leak out, the liquid ammonia will not lose its effectiveness no matter how many years it is stored.
What are the Signs of Leakage From a Liquid Ammonia Cylinder?
Signs of leakage include a strong, pungent odor, visible frost or ice buildup around the cylinder valve or fittings, and a hissing sound indicating the release of pressurized gas. If there is an obvious smell, it means there is a leak. You can use hydrochloric acid solution to test for leaks. If the leakage point encounters hydrochloric acid, white smoke will appear.
Material of Liquid Ammonia Cylinder
Liquid ammonia cylinders are usually made of stainless steel and have excellent corrosion resistance and high temperature resistance. Liquid ammonia cylinders also have high sealing and safety, which can effectively protect ammonia gas from contamination or leakage, have a relatively long service life, and are easy to clean and maintain.

Liquid Ammonia Cylinder Connection Method
Preparation work: Before connecting the liquid ammonia cylinder, you must first make relevant preparation work. This includes wearing protective equipment such as gas masks and gloves, and checking whether connecting tools (pipes, tools, valves, airtight sealants, etc.) are intact.
Clean the cylinder interface: Use a metal brush or sandpaper to clean the cylinder interface surface to ensure that no foreign matter remains.
Install air-tight sealant: Apply an appropriate amount of air-tight sealant to the cylinder interface, not too much or too little.
Install pipes and valves: Connect the pipes and valves to ensure there are no leaks at the connections. If multiple liquid ammonia cylinders need to be installed, a gas pipe connector must be used to ensure that there is no leakage at the connections between multiple cylinders.
Connect to the equipment: Finally, connect the valve to the corresponding equipment to ensure that there is no leakage at the connection part.

Wear breathable protective gloves and necessary protective equipment such as shoes, helmets, goggles or masks to ensure your own safety. Check whether the device and explosion-proof electrical appliances are complete and intact. Check whether there are flammable items, fire sources and other dangerous items in the operating area. Liquid ammonia has a strong pungent smell and is an asphyxiating poison and oxidant, which requires special attention.
Operation Steps For Loading and Unloading Liquid Ammonia Cylinders
Exhaust treatment: If it has been used previously, the liquid ammonia needs to be drained and the pressure in the air valve released to prevent the bottle from exploding.
Place the cylinder: Please ensure that the cylinder is in a horizontal position and cover the gas valve and protective cap.
Connect equipment: Use professional connectors to connect the liquid ammonia cylinder and the receiving device, and make sure the connections are tight.
Open the flow valve: After checking whether the connector is secure, slowly open the liquid ammonia flow valve. Please note that the flow of liquid ammonia should be slow to avoid excessive pressure.
Close the flow valve: After the operation is completed, first close the liquid ammonia flow, and then close the connecting air valve. Unplug the cylinder and store the device in a small environment.
Why Should Liquid Ammonia Cylinders be Placed in Water?
The liquid ammonia cylinder is a special gas storage container that stores high-pressure liquid ammonia gas inside. Since liquid ammonia has a strong vapor pressure at normal temperature and is prone to gas leakage, the liquid ammonia cylinder is stored in water. When the liquid ammonia cylinder is placed in water, the immersion in the water can lower the temperature of the liquid ammonia and reduce the generation of liquid ammonia vapor, thus reducing the risk of gas leakage. At the same time, placing the liquid ammonia cylinder in the water can also prevent the cylinder from being damaged by external forces.
Precautions for Storing Liquid Ammonia Cylinders in Water
When storing liquid ammonia cylinders, first check whether the cylinder is damaged. If it is damaged, it should not be placed in water. The water quality put into the liquid ammonia cylinder also needs to be clean to avoid the impact of impurities or pollutants in the water on the liquid ammonia cylinder or liquid ammonia. The height of the cylinder in the water should ensure that the water level does not exceed half of the cylinder. An excessively high water level may cause liquid ammonia leakage. Cylinders should be stored away from machinery and equipment and other items that are prone to collision to prevent safety issues such as liquid ammonia leakage due to collisions. The room where liquid ammonia is stored should be kept ventilated. If work needs to be performed in the room, workers should wear appropriate safety equipment.
Liquid Ammonia Cylinder Storage Requirements
The environment in which liquid ammonia cylinders are stored is very important. It must be kept in a ventilated, dry, moisture-proof, and light-proof environment to avoid the effects of water vapor, acidic gases, direct sunlight, etc. on liquid ammonia cylinders.
When storing liquid ammonia cylinders, protective measures must be taken into consideration. The shell of liquid ammonia cylinders is very fragile. Collisions, friction and scratches should be avoided as much as possible to avoid danger.
Liquid ammonia cylinders should be stored in a ventilated, clean and dry environment away from fire sources, electrical appliances and other flammable and explosive substances. At the same time, to prevent the cylinder from collapsing or toppling, it must be placed firmly on a stable ground.
The safe use of liquid ammonia cylinders is very important. When storing liquid ammonia cylinders, it is not only to maintain the service life of the cylinder itself, but also to avoid dangerous situations and ensure the safety of personnel and property.
