NINGBO INNO PHARMCHEM CO., LTD. is a trusted supplier of high-performance chemicals that are vital for maintaining product quality and process integrity across various industries. Among our key offerings, Zeolite Molecular Sieves, including types 3A, 4A, 5A, and 13X, play a crucial role in ensuring exceptional purity, particularly in industrial drying and gas purification applications. Their unique porous structure and selective adsorption capabilities make them indispensable for removing moisture and contaminants.

In industrial drying, the objective is often to remove trace amounts of water or other polar impurities from sensitive materials or processes. Zeolite molecular sieves excel in this regard due to their high affinity for water molecules and their precisely controlled pore sizes. The 3A molecular sieve, with its 3-angstrom pores, is highly selective for water, making it ideal for drying reactive monomers, insulating glass, and ethanol, where preventing side reactions or product degradation is critical. Its ability to adsorb moisture rapidly and efficiently ensures that even very low water content levels can be achieved and maintained.

The 4A molecular sieve, with its 4-angstrom pores, serves as a versatile desiccant for a wide range of applications. It effectively removes water from both liquid and gas streams and can also adsorb other small molecules like ammonia and carbon dioxide. Its broad applicability makes it a common choice for general drying tasks in manufacturing, packaging, and laboratory settings. The FDA approval for certain 4A variants further broadens its use in contact with consumables.

For more demanding gas purification tasks, particularly those involving larger contaminant molecules, the 5A and 13X molecular sieves offer enhanced capabilities. The 5A sieve, with 5-angstrom pores, is effective in removing sulfur compounds and carbon dioxide from natural gas and petrochemical streams. It is also used in pressure swing adsorption (PSA) units for the production of high-purity oxygen and nitrogen. The 13X sieve, featuring 10-angstrom pores, is capable of adsorbing larger molecules, making it suitable for desulfurizing and decarburizing various gas streams, including those in refinery operations and air separation units.

The effectiveness of zeolite molecular sieves in these applications is further enhanced by their thermal stability, allowing for regeneration and reuse, which translates to both economic and environmental benefits. By repeatedly adsorbing and desorbing impurities, these materials provide a sustainable solution for maintaining process purity.
