Application&Solutions

• 3A Molecular sieve for Electronics Factory

  In May 2024, South Korea Electronics Factory purchased 24tons molecular sieve for drying the gas in the workshop and Deep drying of insulating transformer oil: 3Å pores selectively adsorb H₂O via ion exchange, achieving <10 ppm moisture for high-voltage equipment.

• 4A Molecular sieve in Refrigeration Plant

  In 2025, a Japan customer bought 5 tons molecular sieve for equipment drying, 4Å molecular sieving removes H₂O/CO₂ to <20 ppm, preventing ice formation in compressor systems at -40°C.

• 5A Molecular sieve for Petrochemical Complex

  In 2025, a Spain customer purchased 5A molecular sieve ,5Å pores exclude C₂H₄ from C₃H₆ via kinetic diameter exclusion in PSA units. The separation effect is very good.

• Molecular sieve for gas drying

  In July 2025, a petrochemical plant in Japan purchased 36 tons of 3A molecular sieve for drying petroleum cracking gas, and after treatment, the gas drying rate reached the target value.

• Molecular sieve for ethanol drying

  In November 2023, a factory in Ethiopia purchased 4A molecular sieve for ethanol drying, and the customer feedback drying value met the ideal value.

• 13X Molecular sieve for LNG Terminal

  In Oct 2025, a Colombia customer bought 10 tons 13X molecular sieve 10Å pores co-adsorb acid gases via chemisorption, reducing CO₂ for cryogenic liquefaction.
