Molecular sieve 13X 1 Scope This standard specifies the requirements, test methods, inspection rules, packaging, marking, storage and transportation of molecular sieve 13X. It is applicable to molecular sieve 13X spherical and strip products and raw molecular sieve 13X powder, which are usually used to dry the general gas, purify raw gas for air separation device (removal of H2O and CO2) and desulfurize natural gas (removal of H2S and mercaptan). 2 Normative references The following referenced documents are indispensable for the application of this document.
