Things to Know While Purchasing Molecular Sieves for medical oxygen concentrator.!

Molecular sieves are used to remove water formed in chemical reactions, the water being capable of modifying the equilibrium of the said reaction. In the pharmaceuticals and fine chemicals industry, molecular sieves are typically used in the synthesis reaction of molecules. This is done to improve the yields and the quality of the final product.

A constantly-growing patient population needs an oxygen-rich air supply close at hand. Whether static or portable, these oxygen concentrating devices operate by passing ambient air through a molecular sieves column. The distinctive properties of the column then separate oxygen from nitrogen in the ambient air and release a flow of up to 94% pure oxygen.

For this application, Sorbead India has supplied the various Grades of Molecular Sieve (Molecular Sieve 3A, Molecular Sieve 5A, molecular

Sieve4A, and molecular Sieve13x) especially for medical oxygen concentrator designs.

Focus on some technical concepts while purchasing molecular Sieves for Medical Applications.

The separation of the various gases from ambient air is accomplished by a porous material known as a synthetic zeolite, which is also known as "molecular sieve". A combination of silica and aluminum organized into a crystalline network, zeolites selectively trap nitrogen molecules in their nanometre-scale cavities, while letting oxygen and other molecules through.

The working standard is the same for medical as with industrial oxygen systems where the air is passed through a set of columns to produce oxygen at 93-95% of purity.

The major difference for medical applications is that the feed flow rate of air being treated is significantly lower and the adsorption cycle time (time for adsorption before switching to desorption) is somewhat shorter than with many industrial systems.

Molecular Sieve 13X for Effective Humidity Control

Molecular Sieves - An Introduction

Molecular Sieves are one of the most commonly found desiccants. With their evenly-sized pores, they can absorb moisture/impurity molecules, which are of the same size. Due to the even size, larger molecules will not be absorbed while the same sized small molecules can easily make their way through.

While Molecular Sieves have many different uses, they are mainly utilized in the column chromatography process. Here the Molecular Sieves act as a stationary phase, attracting the different components of the mixture, which has to be separated. When the chromatography process begins, the components having the highest molecular weight will leave the Molecular Sieve bed first. This happens because the heavier molecules are unable to pass through the molecular pores. It is only after the larger molecules move that the smaller molecules will move forward. Molecular Sieves also find use as desiccants.

Molecular Sieve 13X in Moisture Controlling

There are various grades of Molecular Sieves available in the market. These include Molecular Sieve 3A, 4A, 5A and 13X among others. While all these grades of Molecular Sieves are useful for different purposes, Molecular Sieve 13X is mainly used for the effective control of moisture in packaging, oil and gas and other sectors. The Molecular Sieve 13X is known to have a pore size opening equal to that of the 10A grade. This makes it handy in while removing moisture from liquid and gas refinements as it helps in the effective absorption for bi-molecule and tri-molecules.

There are many other reasons as well why Molecular Sieve 13X is used across industries. Molecular Sieve 13X can effectively co-adsorb CO2 and H2O, H2O and H2S. Molecular Sieve 13X also finds use as a desiccant for medical and compressor uses. This type of desiccant is also used as a catalyze carrier in industries.

Other than effective moisture control, Molecular Sieve 13X is also widely used in the air refining process by removing carbon dioxide and water. It is employed in the Oxygen PSA (Pressure Swing Adsorption) process. One can also effectively use Molecular Sieve 13X desiccant for the successful removal of grease and solvents from different substances.This is one of the most popular uses of Molecular Sieve 13X Other uses include removal of mercaptans and hydrogen sulphide from natural gas using patented Zeochem technology and effective removal of mercaptans and hydrogen sulphide from hydrocarbon liquids.

All these uses prove the high efficiency of Molecular Sieve 13X in not only moisture control but other areas as well

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:

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.
