Low temperature liquid storage tank

Low-temperature liquid storage tanks are specialized vessels designed to store cryogenic fluids such as liquefied natural gas (LNG), liquid hydrogen (LH₂), liquid oxygen (LO₂), and liquid nitrogen (LN₂) at extremely low temperatures (ranging from -162°C for LNG to -269°C for liquid helium). These tanks are critical in industries like energy, aerospace, and healthcare, enabling the safe and efficient handling of cryogenic materials.

Air-heated vaporizer

An Air-heated Vaporizer (also known as an ambient vaporizer) is a heat exchanger that converts cryogenic liquids (e.g., LNG, LPG, LOX, LIN) into gaseous form using ambient air as the heat source. It is widely adopted in energy, industrial gas, and urban gas supply sectors due to its energy efficiency, low maintenance, and safety

Detail

Low-temperature unloading loading arm

Essentially, LNG unloading arms and low-temperature unloading loading arms are the same type of equipment. They are both special devices for loading and unloading low-temperature liquefied gases, mainly used for the loading and unloading operations of liquefied natural gas (LNG). The following is a detailed introduction: Structural composition It is mainly composed of a column, a liquid-phase arm, a gas recovery arm, a balancing device, a nitrogen purging device, an anti-static device, a rotary joint, and an emergency cut-off valve, etc. The lower end of the column is fixed on the loading platform through a connecting base plate. The rotary joint requires reliable sealing and flexible rotation to ensure that the loading and unloading arm can move flexibly within a certain range and achieve connection with the tanker.

Performance characteristics: Low-temperature resistance: It can adapt to low-temperature operating conditions. Usually, the working temperature can reach about -196℃ to 100℃. The pipeline material mostly uses low-temperature-resistant materials such as 304 stainless steel.

High safety: It is equipped with an anti-static device to prevent static electricity from accumulating and generating sparks. At the same time, an emergency cut-off valve is installed, which can quickly cut off the fluid passage in case of an abnormal situation to avoid the expansion of the accident.

Flexible operation: Balancing devices such as spring cylinder balancers with omnidirectional balance are adopted, making the operation of the loading and unloading arm light and labor-saving. It can move with the tanker within the normal moving range of the tanker, improving the loading and unloading efficiency. Technical parameters

Working pressure: Generally, it is about -0.08MPa to 6.0MPa.

Liquid/gas phase caliber: Common ones are DN50, DN25, etc.

Application scenarios It is mainly applied in places such as LNG receiving stations and gas filling stations to realize the transmission of liquefied natural gas between LNG tankers and storage tanks or other equipment, ensuring the safe and efficient loading and unloading of LNG.
