STANDARD 4A MOLECULAR SIEVE

Description

Standard 4A molecular sieve is manufactured for the dehydration of hydrocarbon streams and can selectively remove water from both liquid phase and vapor phase streams. This dehydration process allows the hydrocarbon streams to be further processed in cryogenic separation and is more easily transported. This molecular sieve, with a high adsorption capacity, can bring benefits to a wide range of dehydration applications.

  • used for the dehydration hydrocarbon streams
  • capable of removing water to meet most specifications
  • allows hydrocarbons to be further processed and transported
  • offers an advantageous adsorption capacity
    • Chemical Formula

    (Y)a x [(AlO2)a(SiO2)b] x cH2O      (Y = Na)
