HG/T 2690-2012 (English Version) PDF

Scope: This standard specifies the requirements, test methods, inspection rules, packaging, labeling, storage and transportation of 13X molecular sieves. This standard is applicable to 13X molecular sieve spherical and bar-shaped products, and 13X molecular sieve raw powder. It is mainly used for general gas drying, purification of raw gas in air separation units (removal of HO and CO), and desulfurization (removal of liquid hydrocarbons and natural gas). HS and thiols).
