Things to Know When Purchasing Molecular Sieves.!

2018-09-10T03:09:00.000-07:00

Molecular Sieves are used to purify the gas streams & as absorbents to remove the water or decrease the humidity. in our blog post, we are focused on what are the things we need to know while purchasing absorbents.

Molecular Sieves working principles

The raw material s used in an industrial molecular Sieve has slightly small uniform pores. When other materials come in contact with the molecular sieve. The molecules that are the right size to fit the pores will be absorbed. Molecular sizes are measured in angstroms. Pore sizes molecular Sieve3A & molecular Sieve 4A will absorb the water while larges sizes remove larger hydrocarbons.

How a Molecular Sieve Works

The material used in an industrial molecular sieve has small uniform pores. When other substances come in contact with the molecular sieve, the molecules that are the right size to fit in the pores will be adsorbed. The molecules that are too large to fit will not. Molecular sieves function at the microscopic level; therefore their sizes are measured in angstroms. Pore sizes 3Å and 4Å will adsorb water while larges sizes remove larger hydrocarbons.

Molecular Sieve using raw Materials

In a strictly scientific sense, many regular desiccant dehumidifiers like lime, clay and silica gel also work by filtering molecules of water vapor, but marketable molecular sieves are made of synthetic crystalline alumina silicates. Unlike absorbents found in nature, the mechanism of pore size during manufacture produces selective adsorption characteristics.

The Benefits of Molecular Sieves

Molecular Sieves adsorbents usually adsorb the water much quicker than other adsorbents & same they can decrease the humidity to a much lower level than the standard silica gel. they are also more effective than natural adsorbents for applications that exceed normal room temperature when correctly used they can be effective in reducing water molecules as low as 1ppm in specialized containers or to 10% comparative humidity in packaging.

Molecular sieves typically adsorb water much faster than other desiccant air dryers and they can reduce the humidity to a much lower level than the standard silica gel. They are also more effective than natural desiccants for applications that exceed normal room temperature. When properly used, they can be effective in reducing water molecules as low as 1ppm in specialized containers or to 10% relative humidity in packaging.

Molecular sieve regeneration

While some molecular sieves that remove alcohols and aromatic hydrocarbons use pressure to regenerate the sieve, the molecular sieves that are used for water-adsorption are usually regenerated by heating. For most industrial purposes, these temperatures range from about 250° to 450°F, similar to baking temperature settings for a standard kitchen oven.

Drawbacks of Molecular Sieves

Prices are higher than other forms of adsorbents; however, molecular sieves are also more effective. The actual price per unit and final value will depend upon other factors such as the volume to be dehumidified and the level of dryness needed.

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

2018-09-10T03:00:00.000-07:00

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

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.

steel corrosion protection via Molecular sieve desiccant packs.!

2018-01-27T00:06:00.002-08:00

What is corrosion protection?

Corrosion protection is the use of hostile to consumption chemicals to avert harms to gear or office caused by destructive operators. To address the diverse types of erosion in various materials, Cor-Pro Systems offer the accompanying consumption security techniques to our customers.

steel corrosion protection via Desiccant method

According to DIN 55 473, the purpose of using desiccants is as follows: "desiccant bags are intended to protect the package contents from humidity during transport and storage in order to prevent corrosion, mold growth and the like

The desiccant bags contain desiccants which absorb water vapor, are insoluble in water and are chemically inert, such as silica gel, aluminum silicate, alumina, blue gel, bentonite, molecular sieves etc.. Due to the absorbency of the desiccants, humidity in the atmosphere of the package may be reduced, so eliminating the risk of corrosion. Since absorbency is finite, this method is only possible if the package contents are enclosed in a heat-sealed barrier layer which is impermeable to water vapor. This is known as a climate-controlled or sealed package. If the barrier layer is not impermeable to water vapor, further water vapor may enter from outside such that the desiccant bags are relatively quickly saturated, without the relative humidity in the package being reduced.

"A desiccant unit is the quantity of desiccant which, at equilibrium with air at 23 ± 2°C, adsorbs the following quantities of water vapor:

Calculation of required number of desiccant units

The number of desiccant units required is determined by the volume of the package, the actual and desired relative humidity within the package, the water content of any hygroscopic packaging aids, the nature of the barrier film (water vapor permeability).

Formula for calculating the number of desiccant units in a package (DIN 55 474):

n = (1/a) × (V × b + m × c + A × e × WVP × t)

Molecular Sieve 3A for drying various objects

Understanding Molecular Sieve

Molecular Sieves are one of the most commonly used desiccants for removing moisture from storage and packaging facilities. When we talk about molecular sieve, what comes to mind are Silica Gel balls/beads having uniform-sized pores. Silica Gel is one of the most well-known forms of Molecular Sieves. Others include Activated Carbon and Activated Alumina. The uniqueness of Molecular Sieve Desiccant is that it has all same-sized holes, which allow only molecules of the same size as the pores to pass through. The bigger molecules will not pass through as their size is different from the pore size of the molecular sieve. In this manner, molecular sieves absorb all the moisture present in packaging. Also Check: Want to buy Activated alumina for Transformer Oil Filtration then contact here.

The main use of molecular sieves is in chromatography, the process by which different components of any given mixture are separated for further analysis. In the chromatography process, the given mixture moves through a bed of porous semi-solid substance, (the molecular sieve) where the separation process takes place. As the mixture moves forward, the components with more molecular weight are absorbed first by the molecular sieve. The lesser weighing molecules are always absorbed later. This is how in chromatography, the high absorption powers of molecular sieves are successfully put to use.

Molecular Sieves are divided into various categories, depending on their usage. These include 3A, 4A, 5A, 10A, 13X among others. In this article, we will get to know more about Molecular Sieve 3A.

Molecular Sieve 3A- An Introduction

Molecular Sieve 3A gets its name on the basis of its pore size. This type of molecular sieve has pores the size of 3 Angstrom ( the measurement used for the pore size of molecular sieves) and will allow only the passage of water molecules with lesser size. So when it is placed alongside packed items, Molecular Sieve 3A will absorb all the vapour molecules and not allow dirt and other molecules with pore size more than 3A to pass through. Molecular Sieve 3A desiccant suppliers are witnessing high demand for this desiccant, given its high absorption capabilities.

MolecularSieve is generally an alkali metal aluminosilicate, having the potassium form of type A crystal structure. The pore size of 3 Angstrom is generated when some of the sodium ions from the 4 Angstrom sieve get replaced by potassium ions. Manufacturers of Molecular Sieve 3A advocate more use of this desiccant as it has regular high adsorption rate, high contamination resistance, greater crushing strength and more cyclic times in comparison to other desiccants. Molecular Sieve 3A is also successful in increasing the shelf life of many packed items like food products and pharmaceutical items because of the above-mentioned benefits.

Molecular Sieve Pellets/Beads for Effective Solvent Drying

2017-03-04T02:24:00.000-08:00

Molecular Sieve- A Brief Introduction

Molecular Sieves, like Silica Gel, are well-known desiccants used mainly for removing vapour molecules from oil, liquid and natural gas streams. Available in balls, beads and pellet form, these desiccants are nowadays more preferred to Silica Gel and Activated Alumina because they can absorb humidity molecules in a better manner. Molecular Sieves are also economically viable as they can take in more moisture molecules in lesser period of time and this helps in saving money.

Molecular Sieves are much in demand due to their uniform pore crystalline structure. This added with their large surface area speeds up the absorption process to a large extent. Molecular Sieves work by using the size exclusion principle. When water molecules come in contact with the Molecular Sieve, only those molecules which fit into the pores are absorbed while the larger molecules pass through. The pore size of Molecular Sieves are in the range of 3,4,5 and 10 Angstroms. When the absorption process is going on depending on the pore size, the water molecules will be absorbed or move forward. This is one of the biggest benefits of using Molecular Sieves as desiccants for removing water vapour.

The main difference while using Molecular Sieve and other desiccants like Silica Gel and Activated Alumina is that in Molecular Sieves, the absorbed molecules get trapped while in the others, the absorbed molecules are free to move away. This is why when Molecular Sieves are used, the water molecules are retained in the pores, freeing the remaining area of moisture.

Molecular Sieves pellets are widely used in drying oil and liquid gas streams and solvent drying because this desiccant can hold 22% of its own weight in water. Molecular Sieve beads also witness much demand because their absorption qualities are much superior to other desiccants. These qualities include adsorption possible based on molecular size, molecular affinity for the sieve crystal surface and finally the shape of the molecule.

Molecular Sieve Beads/Pellets in Solvent Drying

Among all the Molecular Sieves beads in use, the Molecular Sieve type 3A is generally used to dry dehydration solvents for electron microscopy. The solvents, which are generally made free from moisture molecules are the most commonly used ones like acetone, ethanol, and methanol. They are generally used in electron microscopy embedding work using epoxy resins, so it becomes very important that they have no traces of moisture in them. This is where the role of Moisture Sieve Beads and Pellets become crucial as they will remove all the traces of humidity from the solvents. What better way of solvent drying that Moisture Sieve beads and pellets.

When the bottles containing the solvents are opened, there are chances that they will pick up moisture from the surroundings so that is why Molecular Sieves are used to dry up the solvents. These dried solvents are used in the final stages of dehydration and embedding. The solvent and the water will be quickly adsorbed onto the molecular sieve surfaces as the small pores can only access the smaller water molecules.

Molecular Sieve 13X for Effective Humidity Control

2017-02-14T03:11:00.000-08:00

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

Molecular Sieve Adsorbents for Effective CO2 Removal

2016-12-27T21:37:00.003-08:00

What are Molecular Sieve Adsorbents?

When we think of adsorbents, the first thing that comes to mind is Silica Gel. This, however, is not the only adsorbent being used by companies to remove moisture from closed spaces. Molecular Sieve Adsorbents are high-quality desiccants, which are equally effective in maintaining optimum humidity levels. Molecular Sieve Adsorbents are basically crystalline alumino-silicates, commonly known as zeolites.

They are manufactured in such a manner that they have a porous crystalline structure. These pores can re-adsorb water or other polar molecules. With the help of strong ionic forces or electrostatic fields (which are due to the presence of cations such as sodium, calcium and potassium) and with enormous internal surface area of around 1‘000 m2 /g, molecular sieves can take in a large amount of water or other compounds. If the fluid, which is to be adsorbed is a polar compound, it can be adsorbed with high loading, even during very low concentrations of the contaminants. Molecular sieves adsorbents are therefore capable of removing many gas or liquid impurities to very low levels (ppm or less). Another popular positive factor about Molecular Sieve Adsorbents is that they can separate gases or liquids by molecular size or polarity. This is largely made possible by the fact that the pore openings of the Molecular Sieve Adsorbents have the same size as a wide range of products. As the water molecule size is smaller than the Molecular Sieve Adsorbents size, they will be easily absorbed thus maintaining optimum moisture levels.

Molecular Sieve Adsorbents for Carbon Dioxide Adsorption

One may think that Molecular Sieve Adsorbents are only used for water vapour adsorption. That is, however, not the only thing it is used for. Molecular Sieve Adsorbents are utilized for adsorption of other compounds as well. One of them is Carbon Dioxide. Molecular Sieve for CarbonDioxide removal is very common among companies.

For obtaining an adsorbent with typical molecular sieve properties one makes use of thermal processing of granulated carbonaceous material at temperatures of 970-980 degree Celsius. This is usually done in the presence of gases to prevent the oxidation of the carbon material. At temperatures of around −196° C, the adsorption takes place in its micro-pores, whereas nitrogen and argon are taken in at the same temperature at the surface of transitional pores and macro-pores only.

It is mainly oil and natural gas companies, which make use of Molecular Sieve Adsorbents to remove carbon dioxide. It is mainly used to remove CO2 from stream cracked gas, Liquid Petroleum Gas and different atmospheric gases. Mainly, Molecular Sieve 3A and 4A is preferred for the above mentioned purposes.

There are many reasons why Adsorbents 3A and 4A are widely used for carbon dioxide removal. The first being these adsorbents have a high and very rapid adsorption rate. Another factor is that molecular sieve adsorbents are known to have a consistent adsorption speed and have a higher contamination resistance. All these factors make Molecular Sieve adsorbents the ideal substance for removing carbon dioxide from oil and natural gas industries.

5A Molecular Sieves For Hydrogen Production about Desiccant and Zeolites

2015-10-21T03:21:00.002-07:00

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.
