 Petroleum Additives 1/16" Molecular Sieve 5A
Product introduction
 
Molecular sieve 5a is an effective absorbing solution for various applications. This most reliable desiccant can be used for:

Separating process of normal paraffin

Removing moisture and hydrocarbons from refrigerants

Drying of natural gas

Removing carbon dioxide from cracked gas and natural gas

Drying and purifying PSA oxygen

Drying and Separation of aromatics

Liquefied petroleum gas sweetening

Refinement of ethanol by drying moisture and carbon dioxide

Pressure Swing Adsorption process of oxygen and hydrogen

 
Zeolite molecular sieve is a aluminosiliate with uniform pores. These pore diameters are similar in size to small molecules. Thus molecules with diameter less than the pore size can enter molecular sieve and be adsorbed, while molecules with diameter bigger than the pore size can not go into molecular sieve and be excluded (Tab. 1). Moreover, molecular sieve pore size can be precisely adjusted through introducing of different metal ions such as Na+(4A, 13X), K+(3A), Ca+(5A, CaX), Li+(LiLSX, LiLX). This property enables molecular sieve to separate molecules of different size. Another important property of molecular sieve is it is easier to adsorb polar molecules other than non polar molecules, thus makes it possible to separate molecules by its polarity

To offer a slightly larger pore opening, calcium is used in an ion exchange to produce Type 5A molecular sieve. A sodium ion is exchanged with the slightly smaller calcium ion, which increases the pore size of the crystal. Type 5A is able to adsorb certain mercaptans while still small enough to block larger hydrocarbons from entering the crystal. These properties allows this molecular sieve to be utilized in LNG and LPG refining to remove sulfur compounds while allowing the desired hydrocarbons to pass through to the product stream. Type 5A is also useful for producing relatively pure streams of hydrogen or oxygen since it is able to adsorb nitrogen, carbon monoxide, and other contaminants.

Regeneration
1. Removal of water: it depends on the pressure, temperature and water content of the regeneration gas. Under normal circumstances, the dry gas at 200~350℃ will pass through the molecular sieve bed for 3~4 hours under the pressure of 0.3~0.5kg/cm to bring the outlet temperature to 110~180℃ and cool.
2. Removal of organic matter: replace organic matter with water vapor, and then remove water.
