Krypton Extraction Equipment
Rare gases such as krypton and xenon are highly valuable for many applications, but their low concentration in air makes direct extraction a challenge. Our company has developed krypton-xenon purification equipment based on cryogenic distillation principles used in large-scale air separation. The process involves pressurising and transporting liquid oxygen containing trace amounts of krypton-xenon via a cryogenic liquid oxygen pump to a fractionation column for adsorption and rectification. This produces by-product liquid oxygen from the upper-middle section of the column, which can be re-used as required, while a concentrated crude krypton-xenon solution is produced at the bottom of the column.
Our refining system, independently developed by Shanghai LifenGas Co., Ltd., features proprietary technology including pressurised evaporation, methane removal, oxygen removal, krypton-xenon purification, filling and control systems. This krypton-xenon refining system features low energy consumption and high extraction rates, with the core technology leading the Chinese market.
