Molecular Sieve 5A – How Are They So Beneficial?

Molecular Sieve – An Introduction

Just like Silica Gel and Activated Alumina, Molecular Sieve is another widely used adsorbent. Molecular Sieve is made up of numerous even-sized pores, which have the same diameter. These pores are designed in such a manner that only small molecules can pass through while the larger molecules will be left behind as they cannot be absorbed. Molecular Sieves mainly find use as desiccants in petroleum and natural gas industries, waste water treatment plants among others. Usually, the diameter of a molecular sieve is measured in terms of angstroms or nanometers. Molecular Sieves are available in different sizes like 3A, 4A, 5A, 10X, 13X and 13X-AS.

Molecular Sieve 5A

In this article, we will take a closer look at the Molecular Sieve 5A adsorbent. This type of Molecular Sieve consists of an alkali alumina silicate carbon manufactured as a Type A crystal structure. As the name suggests, this Molecular Sieve has a pore size of 5A or 5 angstrom. Water molecules having a pore size lesser than 5A like 3A and 4A are automatically adsorbed by this Molecular Sieve while those bigger than 5A are left behind. Materials with diameters larger than 5A include ISO compounds and different types of 4-carbon rings. They are generally not adsorbed by the 5A grade of Molecular Sieve.

Uses of Molecular Sieve 5A

The main use of Molecular Sieve 5A is in the liquid and natural gas industry. Molecular Sieve 5A is employed in the purification and separation of liquids and natural gases. This type of Molecular Sieve is perfect for splitting up normal and isomerous alkanes. It is used in adsorbing water vapour, carbon dioxide and other impurities from gas streams. The pressure swing for these gases can also be adjusted with the help of Molecular Sieve 5A. 

Another important utilization of Molecular Sieve 5A is in finding out the correct composition using volume, density, water content, strength and many other chemical compositions. 

Benefits of Using Molecular Sieve 5A

Molecular Sieve 5A
There are many benefits of using Molecular Sieve 5A. The first is that it can be regenerated by simply heating up to 200-300 degree Celsius. As it can be regenerated, this Molecular Sieve can be used again and again. This helps in saving money as well as time. Another advantage is that Molecular Sieve 5A is the best sieve for the purification of medical oxygen generator. The latter functions better with the help of Molecular Sieve 5A.

5A Molecular Sieves For Hydrogen Production about Desiccant and Zeolites

A desiccant is a substance which is mainly used in absorbing water. It is widely used in excluding humidity which usually degrades and damages the products that are sensitive to moisture.

A desiccant is a substance which contains the properties of hygroscopic nature. One of the vital characteristics of a desiccant is that it is a low surface vapour pressure. When the desiccant is dry and cool, its surface vapour pressure becomes low and it can attract moisture from air, especially when it is moist and pressure vapour is high. When the desiccant becomes hot and wet, its surface vapour pressure reaches its highest point and excludes water vapour to the surrounding of the air.

Zeolites are a volcanic kind of rock which are consisted of hydrated aluminosilicates of the alkali metals of the earth. Zeolites comprise of three dimensional frameworks of crystals of alumina, anions, or tetrahedrite silica which are strongly bonded from all the corners.

When the level of humidity in the air stream decreases below the saturation point of the zeolite, it starts to release moisture back into the air stream. Hence, it does not eliminate moisture completely. But it only retains or release the moisture, depending on the relative level of humidity of the air stream and the saturation point of the zeolite.

Molecular Sieve For Hydrogen Purification:

Molecular Sieve For Hydrogen Purification
The role of "molecular sieve for hydrogen purification" is that it helps in producing hydrogen which does not occur till the end of stream-methane process of reformation. Before the molecular sieve is made in use, the feed stock which looks more or less like a natural gas, has to undergo a process of hydrodesulfurization, a reformation of stream process, a process of heat recovery and a CO conversion process. The afore mentioned process-especially will further breakdown the complex form of structure of molecular feed-stock, preparing it for the last stage for purification of hydrogen.

Hydrogen Purification With The Help of 5A Molecules:

5A molecules are specialized in the separation of straight and chained-like form of hydrocarbons from one another. 13X molecular sieve is proficient in the exclusion of any additional CO2 or NH3, if found anywhere. At this point, it will count upon the materials used during the feed stock. There are more than 200 hydrogen which produces plants in the world which are listed in the link mentioned below. Hydrogen plays a pivotal role in many scientific and industrial applications in making the agent pure.

Applications:

It is applied in petroleum gas which is mainly liquid in form and is used in natural gas process.


It is used on the basis of the required amount of purification and specification.


The production of oxygen and hydrogen is depending mainly on the swing of the pressure in the process of adsorption.
