Cryogenic Distillation Column

Cryogenic distillation column is a core device that uses ultra-low temperatures (usually below -150°C) to achieve efficient gas separation. As a key device in the field of cryogenic technology, it accurately separates mixed gases (such as air, natural gas, industrial exhaust, etc.) into high-purity products through the differences in the condensation points of each component. It is an indispensable "separation heart" in the air separation, petrochemical, new energy and other industries.

Core technology advantages

1. Ultra-low temperature precision separation

Using patented tray/filler design, an accurate temperature gradient is established within the cryogenic distillation column to ensure that nitrogen, oxygen, argon and other components are condensed and precipitated step by step, and the purity can reach 99.999%.

2. Energy efficiency is more revolutionary than

Integrated high-efficiency heat exchange network and intelligent temperature control system reduces energy consumption by 30% compared to traditional separation equipment, and increases liquefaction rate by 20%, significantly reducing operating costs.

3. Modular anti-extreme design

The double-layer vacuum insulated cold structure is combined with special low-temperature steel (such as 304L/316L stainless steel), which withstands a deep cold environment of -196℃ and a high pressure of 10MPa, and has a leak-free operating life of more than 20 years.

Industry application scenarios

• Air separation field: Extracting high-purity oxygen/nitrogen/argon from the air, supporting semiconductor manufacturing and medical oxygen supply
• LNG liquefaction: Separate methane and ethane from natural gas to help clean energy development
• Hydrogen energy industry: purify industrial by-product hydrogen to fuel cell grade (99.97%+)
• Chemical recycling: Recover rare gases from ethylene cracking gas to realize resource circulation
