In the laboratory, molecular sieves are used to dry solvent. For example, in the liquid natural gas (LNG) industry, the water content of the gas needs to be reduced to less than 1 ppmv to prevent blockages caused by ice or methane clathrate.
Molecular sieves are often utilized in the petroleum industry, especially for drying gas streams. Molecular sieves can be microporous, mesoporous, or macroporous material. According to IUPAC notation, microporous materials have pore diameters of less than 2 nm (20 Å) and macroporous materials have pore diameters of greater than 50 nm (500 Å) the mesoporous category thus lies in the middle with pore diameters between 2 and 50 nm (20–500 Å). The pore diameter of a molecular sieve is measured in ångströms (Å) or nanometres (nm). Other molecular sieves are used as desiccants (some examples include activated charcoal and silica gel). Some molecular sieves are used in size-exclusion chromatography, a separation technique that sorts molecules based on their size. As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight (which are unable to pass into the molecular pores) leave the bed first, followed by successively smaller molecules. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.
