Molecular sieve 5A, also called zeolite 5A or zeolith 5A, is one type of aluminosilicate crystal with average pores measuring of 5 angstrom (0.5 nm). Molecular with kinetic diameter larger than 5 angstrom will be adsorbed by zeolite 5A, otherwise be excluded. Zeolite 5A molecular sieves are typically used for normal- and iso-paraffins separation, removing water, carbon dioxide, hydrogen sulfide from sour natural gas, while decreasing COS formation.
The principle of PSA-pressure swing adsorption hydrogen production is to use adsorbents to easily adsorb high-boiling components under the same pressure, but not easy to adsorb low-boiling components.
Molecular sieve is a special molecular sieve for pressure swing adsorption hydrogen production, pressure swing adsorption oxygen production, pressure swing adsorption carbon monoxide production, and normal isoparaffin separation.
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.
JLOX-500 series molecular sieve are mainly used in PSA oxygen generator for generation of high purity oxygen with the advantages of faster adsorption rate, higher oxygen production rate and longer use life.oxygen purity is up to 93%±3%
