In addition to air separation, in what fields does 13X molecular sieve have applications?

Petrochemical Industry

• Gas Drying: It is used for drying and dehydrating various industrial gases such as cracked gas and refinery gas. It can effectively remove the moisture content, preventing equipment corrosion and pipeline blockage, and ensuring the smooth progress of subsequent processes. For example, in an ethylene cracking unit, it deeply dries the cracked gas to guarantee product quality and the stable operation of the unit.
• Desulfurization and Decarbonization: It can adsorb and remove acidic gases such as hydrogen sulfide and carbon dioxide from natural gas and synthesis gas, achieving gas purification. In a natural gas purification plant, for instance, 13X molecular sieve can reduce the acidic impurities in natural gas to meet the standards for pipeline transportation and industrial use.
• Aromatic Separation: In the production process of aromatics, it is used to separate and purify aromatic compounds such as benzene, toluene, and xylene. By taking advantage of its selective adsorption characteristics for different molecular structures and sizes, it improves the purity and recovery rate of aromatics.

Natural Gas Processing

• Dehydration: It is a commonly used adsorbent for natural gas dehydration. It can reduce the water content in natural gas to an extremely low level, preventing the formation of hydrates under low-temperature or high-pressure conditions, which could block pipelines and equipment. This ensures the safe transportation and storage of natural gas.
• Removal of Heavy Hydrocarbons: It can adsorb heavy hydrocarbon substances in natural gas, making the composition of natural gas more in line with the requirements for pipeline transportation and end use, and improving the calorific value and combustion efficiency of natural gas.

Environmental Protection

• Waste Gas Treatment: It can be used to adsorb organic pollutants in industrial waste gas, such as volatile organic compounds (VOCs) like benzene, toluene, and xylene, as well as harmful gases such as sulfur dioxide and nitrogen oxides, achieving the purification and compliant discharge of waste gas, and reducing environmental pollution.
• Waste Water Treatment: In some waste water treatment processes, 13X molecular sieve can be used to adsorb and remove pollutants such as heavy metal ions and organic substances from waste water, playing a role in purifying water quality and contributing to the recycling of water resources.

Other Fields

• Medicine: In drug synthesis and separation processes, it is used as an adsorbent to separate and purify drug intermediates and active ingredients. By leveraging its high selectivity and adsorption performance, it improves the purity and quality of drugs.
• Refrigeration: In refrigeration systems, it is used as a desiccant and purifier to remove moisture and impurities in the refrigeration cycle, preventing ice blockage and system failures, and improving refrigeration efficiency and the reliability of equipment.
• Electronic Industry: It is used for the purification of electronic gases. For example, in the semiconductor manufacturing process, it purifies gases such as hydrogen, nitrogen, and argon used, removing trace impurities to ensure the production quality of electronic components.
