The effectiveness of molecular sieves in industrial applications hinges on their specific type, each designed with unique pore structures to cater to different separation and purification needs. NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of zeolite molecular sieves, including the widely used 3A, 4A, 5A, and 13X types, each with distinct advantages.

3A Molecular Sieves: Characterized by a pore opening of approximately 3 angstroms, 3A molecular sieves are primarily used for drying highly polar molecules like water and for dehydrating unsaturated hydrocarbons and alcohols. Their selective adsorption of water makes them ideal for applications such as the drying of natural gas and cracked gases in petrochemical processes, and for use in insulated glass units.

4A Molecular Sieves: With a pore opening of about 4 angstroms, 4A molecular sieves are versatile general-purpose drying agents. They are effective in adsorbing water, ammonia, and certain hydrocarbons. Common applications include the dehydration of industrial gases like hydrogen, argon, and nitrogen, as well as the drying of butane and organic liquids. They are also used in the automotive industry for drying brake air.

5A Molecular Sieves: Featuring a pore opening of 5 angstroms, 5A molecular sieves are excellent for separating normal paraffins from branched-chain hydrocarbons, making them crucial in the refining industry. They also exhibit strong adsorption capabilities for molecules like CO2, H2S, and mercaptans, making them valuable for natural gas sweetening and purification. Their ability to desulfurize and remove specific contaminants enhances the quality of various hydrocarbon streams.

13X Molecular Sieves: These sieves have the largest pore opening among the common types, approximately 10 angstroms. This makes them highly effective for adsorbing larger molecules, including water, CO2, and sulfur compounds. 13X molecular sieves are widely used in air separation to remove water and CO2 prior to cryogenic distillation, and in pressure swing adsorption (PSA) units for producing high-purity oxygen and nitrogen. Their high adsorption capacity also makes them suitable for general gas purification and desulfurization.

NINGBO INNO PHARMCHEM CO.,LTD. provides these critical molecular sieve types, backed by technical expertise to help clients select the most appropriate material for their specific industrial demands. By understanding the unique properties of each type, businesses can significantly enhance their separation and purification processes.
