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 separation equipment

Air separation equipment is a critical industrial technology that extracts pure oxygen, nitrogen, and argon from ambient air through various physical and chemical processes. These systems are widely used in industries such as steelmaking, healthcare, chemical production, and electronics manufacturing.

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

Skid-mounted nitrogen and oxygen generator

The skid-mounted nitrogen generator is a modular nitrogen production equipment that integrates air compression, purification, and separation. It has the advantages of rapid deployment, small footprint, and easy operation, and is widely used in petrochemical, new energy, food and pharmaceutical industries.

Light hydrocarbon gas refers to a class of hydrocarbon compounds with short carbon chains that are gaseous at standard temperature and pressure (STP, 25°C, 101.325 kPa). It is a crucial raw material in the energy and chemical industries.

1. Core Characteristics

Carbon chain length: The number of carbon atoms in each molecule is typically between 1 and 4. This short chain structure is the key reason for its gaseous state and "light" property.

Main components: It mainly includes methane (CH₄), ethane (C₂H₆), propane (C₃H₈), and butane (C₄H₁₀). Among them, methane is the primary component of natural gas.

Physical state: It is gaseous at room temperature and atmospheric pressure. However, it can be converted into a liquid state (liquefied petroleum gas, LPG) through compression or cooling for convenient storage and transportation.

2. Main Sources

Natural sources: It is mainly extracted from natural gas fields or as "associated gas" produced during crude oil mining.

Artificial sources: It is a by-product of petroleum refining processes (such as catalytic cracking) and natural gas processing (to remove impurities and separate different components).

3. Typical Applications

Energy field:

As civil fuel: Propane and butane are the main components of LPG, which are widely used for cooking and heating in households.

As industrial fuel: It is used in industrial boilers and kilns due to its high combustion efficiency and low pollution.

Chemical industry: It serves as a raw material for producing basic chemical products. For example, ethane and propane are cracked to produce ethylene and propylene, which are the core raw materials for plastics, synthetic fibers, and rubber.
