Table of Contents
Petrochemical & Refining
13X molecular sieve desiccants (pore size ~10Å) is widely used across industries due to its large pore structure and strong adsorption capacity. Below are its main applications and technical details:
Gas Drying and Purification
Air Separation Units (ASU): Removes H₂O and CO₂ before cryogenic air separation to prevent freezing and equipment blockages.
Industrial Gas Drying: Applied in compressed air, nitrogen, hydrogen drying to ensure high gas purity.
Natural Gas & LPG Dehydration: Lowers dew point to prevent pipeline corrosion and hydrate formation.
Chemical & Petrochemical Industry
Liquid Hydrocarbon Desulfurization: Adsorbs H₂S and mercaptans to improve fuel quality.
Catalyst Carrier: Used in petroleum cracking and hydrogenation to enhance catalytic efficiency.
Solvent Recovery: Captures VOCs like benzene and toluene, reducing emissions.
Environmental Protection & Waste Gas Treatment
Industrial Waste Gas Purification: Removes acidic gases such as SO₂ and CO₂ to meet emission standards.
Papermaking Wastewater Treatment: Composite sieves effectively remove color, suspended solids, and COD.
Pharmaceutical & Electronics Industry
High-Purity Solvent Dehydration: Ensures solvent purity (ethanol, isopropanol) for synthesis and electronic cleaning.
Moisture Protection for Electronics: Prevents moisture damage in precision components.
Other Specialized Applications
Oxygen Enrichment: In PSA oxygen generation, selectively adsorbs N₂ to produce high-purity O₂.
Food Packaging Desiccant: Prevents moisture-induced spoilage in food products.
With high adsorption capacity (static water adsorption ≥25%), excellent regenerability (thermal desorption at 200-350°C), and superior mechanical strength (attrition rate ≤0.2%), 13X molecular sieve remains essential in energy, chemical, and environmental industries.
