What is molecular sieve dryer?
What is molecular sieve dryer?
Molecular sieves are in the family of desiccants, also known as adsorbents, used for hydrocarbon drying, described as the removal of dissolved water from hydrocarbon gases and liquids. They may also be used for final product dehydration to achieve high levels of dryness to meet water quality specification.
Are molecular sieves drying agents?
Considered a general-purpose drying agent in polar and nonpolar media. This sodium form represents the type A family of molecular sieves. Effective pore opening is 4Å, thus excluding molecules of effective diameter >4Å, e.g., propane.
Can molecular sieves be reused?
3A Molecular Sieve regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 3A Molecular Sieve heat to 250ƒ. Keep 3A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.
What is the most common drying agent?
Common drying agents are anhydrous inorganic salts that acquire waters of hydration when exposed to moist air or a wet solution. For the most common drying agents such as sodium sulfate or magnesium sulfate, the crystals form larger clumps when they absorb water.
Is silica gel a molecular sieve?
Free moisture fits into the uniform pores of molecular sieve at a higher rate than in silica gel….Differentiators.
| Property | Silica Gel | Molecular Sieve |
|---|---|---|
| Structure | Amorphous with many irregular pores | Defined, with uniform crystalline pores |
What are the different sizes of molecular sieves?
Also SINOCATA offer specialty molecular sieves for your unique applications. About the form and sizes, A 4×8 mesh size of zeolite molecular sieve is normally used in gas phase applications, while the 8 x12 mesh size is common in liquid phase applications. The powder forms of the 3A, 4A, 5A and 13X sieves are suitable…
What can 3A EPG molecular sieve do for ethylene?
3A EPG Molecular sieve has an cryogenic separation effect in the ethylene plant and can do selective adsorption to the water and debris in the raw material gas. Special molecular sieve for ethylene can also realize deep dehydration and drying to a variety of gas and liquid at a lower temperature.
What can molecular sieve type 13X be used for?
Molecular Sieve Type 13X is capable of adsorbing the same compounds as types 5A, 4A, and 3A and is commonly used for air generation in the Medical Oxygen industry and air compressor systems, utilization as a catalyst carrier, and co-adsorption of CO2, H2O, and H2S for gas dryers and purifiers.
Why do you need an oxygen rich molecular sieve?
Removal of the residual ammonia and water in hydrogen and nitrogen protection gas after the ammonia decomposition and PSA enrichment oxygen. Oxygen-rich molecular sieve has high a separation performance of oxygen and nitrogen and sufficient oxygen production rate.
