Core Processes and Technological Features
Our system employs a mature air pretreatment + molecular sieve purification + cryogenic distillation process:
Air Compression and Precooling - Ambient air is compressed and precooled to effectively remove moisture and impurities, improving downstream separation efficiency.
Cryogenic Cooling and Liquefaction - High-efficiency heat exchangers and expanders are used to cool the air to extremely low temperatures, achieving oxygen liquefaction.
Distillation and Fractionation - In the air separation unit, fractionation is performed according to the boiling points of different gases to obtain high-purity liquid oxygen.
Safe and Reliable Storage and Transportation System - Liquid oxygen is stored in vacuum-insulated storage tanks and can be transported to end-use points via dedicated pumps and pipeline systems.
