Cryogenic liquids in the industrial sector, endowed with ultra-low temperature properties, high energy density, and versatile application scenarios, have emerged as the critical backbone of modern industrial production, energy supply, and high-tech industries. Typically subjected to deep liquefaction processes, these liquids boast temperatures ranging from -162℃ (LNG) to -269℃ (liquid helium), coupled with advantages such as high purity, ease of storage and transportation, and direct usability upon vaporization. The core product portfolio primarily includes Liquefied Natural Gas (LNG), Liquid Nitrogen (LN₂), Liquid Oxygen (LO₂), Liquid Argon (LAr), and Liquid Carbon Dioxide (LCO₂), which are tailored to meet the precision needs of diverse industrial scenarios.
As a clean and efficient energy carrier, Liquefied Natural Gas (LNG) is stored in a liquefied state at -162℃, offering an energy density 625 times that of gaseous natural gas. It serves not only as a premium fuel for transportation and industrial heating but also finds wide-ranging applications in distributed energy stations and chemical raw material synthesis, facilitating the achievement of low-carbon emission reduction goals. Liquid Nitrogen (LN₂), leveraging its extreme low temperature of -196℃ and chemical inertness, stands as an ideal medium for industrial refrigeration, food freezing, electronic semiconductor manufacturing, and medical cryopreservation, while also playing a pivotal role in oilfield fracturing and pipeline purging. With its high-purity oxygen content, Liquid Oxygen (LO₂) acts as a core raw material for metallurgical steelmaking, aerospace propellants, and medical emergency services, providing power support for high-temperature smelting and extreme-environment operations. Liquid Argon (LAr), valued for its inertness and low-temperature properties, proves indispensable in welding protection, photovoltaic silicon wafer production, and superconducting technology R&D, ensuring process precision and product quality. Meanwhile, Liquid Carbon Dioxide (LCO₂) is extensively utilized in food preservation, chemical synthesis, dry ice production, and environmental carbon sequestration, enabling resource recycling.
The safe and efficient application of these cryogenic liquids is inseparable from the support of professional cryogenic storage, transportation, and vaporization equipment. Their modular supply model and eco-friendly characteristics are driving the upgrading of industrial production towards efficiency, low carbon emissions, and sustainability, solidifying their position as an indispensable core medium in the modern industrial system.
