Molecular sieves beads and pellets are applicable in different industries, some of which include medicals, refineries, natural gas, coal chemical, and oxygen generation among others. Our expertise in the supply of quality molecular sieves has allowed us to work with clients from all over the world.
Molecular sieve 4A, also called zeolite 4A or zeolith 4A, is one type of aluminosilicate crystal with average pores measuring 4 angstroms (0.4 nm). Molecular with kinetic diameter smaller than 4 angstroms will be adsorbed by zeolite 4A, otherwise, be excluded. Zeolite 4A molecular sieves are typically used for dehydration in the air brake systems, natural gas drying.
Natural gas must be dehydrated to remove water vapor. Water vapor causes the formation of hydrates, over saturation of natural gas, and corrosion of equipment. The high pressure increases saturation and creates more water vapor. Hydrates cause freezing and blocking of pipelines, valves, and other equipment, bringing production to a halt. Oversaturated gas does not meet pipeline specifications, which must be removed in order to sell.
