4A Molecular Sieve
Deep dew point?……One answer: Petrotat 4A Molecular Sieve
For over 10 years, we have worked closely with industry stakeholders to enable successful sustainable process. With PETROTAT 4A Molecular Sieve, PSA/TSA air dryers can be more durable and require fewer costs for maintenance.
Petrotat 4A Molecular Sieve is a synthetic crystalline aluminosilicate with a regular micropore structure.; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Petrotat type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
Our 4A Molecular Sieve is a widely used adsorbent for many different applications. Like compressed air drying, natural gas dehydration, CNG drying, Automobile air condition system. Petrotat 4A exhibits high water adsorption capacity at low partial pressures and at temperatures up to 100 °C.
