The pore size of 3A molecular sieves is 3Å (0.3 nm), allowing only smaller molecules such as H₂O (2.6Å) to enter the pore channels, while hydrocarbon molecules like methane (CH₄, 3.8Å) and ethane (3.8Å) are effectively blocked. This enables selective adsorption. Molecular sieves are widely used for removing impurities like H₂S and CO₂ from gases and serve as ideal adsorbents for deep dehydration of natural gas.
Why Deep Dehydration of Natural Gas Is Necessary:
• Prevention of Ice Blockages: In high-pressure pipelines or low-temperature conditions (such as LNG liquefaction), water vapor can freeze, leading to valve blockages and flow instability.
• Corrosion Inhibition: The coexistence of H₂O with H₂S/CO₂ forms acidic electrolytes, accelerating stress corrosion cracking in pipelines.
• Heating Value Optimization: Moisture dilutes the calorific value of the gas. After dehydration, the heating value can increase by 2–3% (by volume).
• Equipment Protection: Prevents turbine and compressor damage caused by liquid water impact—droplet erosion rates can be reduced by up to 90%.
JOOZEO’s 3A molecular sieves feature strong adsorption capacity and low attrition rate, making them a highly efficient choice for deep drying of natural gas.
