About HengYe ® Inc.

Hengye offers a wide range of molecular sieve products, which are specialized to perform specific separation tasks that allow our users to create a cleaner, higher value end product that meets environmental and industrial requirements. Hengye offers type 3A, 4A, 5A, 13X and specialty zeolites, which have different adsorption capabilities and selectivity and are used in a wide range of industrial processes such as natural gas purification, air separation, petroleum refining, industrial drying, and more. Depending on your requirements, our various molecular sieves can adsorb a range of contaminants from compounds such as water, which has a relatively small molecular diameter, to molecularly larger compounds such as heavy mercaptans and sulfides.

Activated alumina is commonly used in bulk dehydration processes and frequently used as a guard layer to protect more expensive adsorbents and catalysts. As an desiccant, activated alumina is most commonly used to selectively remove water from gases or liquids and can be applied in both PSA and TSA units.
Regenerable activated alumina relies on its physical adsorption properties to adsorb moisture and other contaminants from liquid or vapor streams and can be applied in both PSA and TSA units. Activated alumina can be used to purity various feed streams, such as removing fluorine from drinking water, for purifying hydrocarbon streams, or for drying liquids and gases. Activated alumina offers a high physisorption capacity while maintaining durability and is suitable for cryogenic air purification including use in air dryers and the purification of carbon dioxide, nitrogen, oxygen, and more.
