Molecular Sieve
Materials for nitrogen generation, oxygen removal, drying and gas purification. Explore Haina’s CMS grades and complementary adsorbent materials.

Match the sieve to the molecules you need to remove.
Zeolite molecular sieves use defined pore openings and adsorption affinity to separate impurities. Start with the feed composition and outlet target, then choose a grade for selective drying, hydrogen purification or air pretreatment.

Industry Applications

01 · ETHANOL & SOLVENTS
Ethanol and Solvent Production
Fuel ethanol plants and solvent producers use molecular sieves where residual moisture affects product quality or downstream use.
3A is a starting point for compatible ethanol and solvent streams. Product grade, water specification and throughput guide the selection.

02 · INDUSTRIAL HYDROGEN
Hydrogen Supply and Refining
Industrial hydrogen suppliers and refineries specify hydrogen purity for downstream production and refining. Where a site uses PSA, molecular sieves can form part of the adsorbent bed.
5A PSA-H is a candidate for compatible PSA duties. The photo shows a hydrogen production facility as industry context.

03 · INDUSTRIAL GASES
Industrial Air Separation
Industrial gas producers use adsorbents upstream of cryogenic air separation units that supply nitrogen, oxygen and other gases.
13X-APG is used for air pretreatment where water and carbon dioxide limits matter. Share your inlet conditions and contaminant targets.
Where Haina Fits
Ethanol and Solvent Production
Start with 3A for ethanol duty. Share inlet water, required outlet water, throughput and the regeneration method.
Hydrogen Supply and Refining
Review 5A PSA-H against the full feed analysis, pressure range, required purity and cycle design.
Industrial Air Separation
Consider 13X-APG for prepurification. Provide inlet conditions, contaminant loading and regeneration conditions.
