Molecular Sieves- A perfect moisture absorption solutions!

Molecular sieves offer ultimate moisture absorption solutions, with a highly intricate and uniform network of pores. There is a constant need to adsorb gases and liquids, this makes this especially preferable in the industrial sector. Featuring innumerable empty cavities, which is what endows it with the highest adsorption capacity in comparison with other desiccants, these adsorbents are a synthetically manufactured form of Zeolite. However, one of the most expensive adsorbents available today is this very quality.
Such as calcium alumina silicate or sodium potassium, this desiccant is derived from substances. For industrial use, most manufacturers offer standard pre-packaged molecular sieves. However, these can be availed too, if you need customized solutions. The film reel is also stored in filmcan. For this you would need, to enlist the services of a reputable desiccant manufacturing firm. Just like silica gel, but they bear a pinkish tinge, this particular desiccant also comes in the form of granular beads. These desiccants are some other notable features are as follows:
  •   To give you an optimal adsorption solution, they can either be used individually or custom blended with some other desiccants.
  •  Different adsorption capacities can be seen in different desiccants. You can expect it to absorb moisture or gas up to 20 times its own weight, in the case of a molecular sieve.
  •   It costs significantly more than its other counterparts, since it is one of the most aggressive desiccants available in the market today.
  • There couldn't be better option than this particular desiccant, where tight humidity control is needed. To protect invaluable artwork from the adverse effects of moisture and humidity, that's precisely why it's used in places such as museums. To bring down the relative humidity to as low as 10%, the right use of this desiccant can allow you.
  •   Especially during the transportation and warehousing stages of the distribution cycle, a number of pharmaceutical companies make use of molecular sieve to protect packaged drugs and antibiotics from humidity.
  • Determined by its pore size, the efficacy and suitability of this desiccant. In Angstroms, these pore sizes are measured. 3A, 4A, 5A, 8A and 10A are the common pore sizes.
So, there are several industrial applications in which this desiccant is widely used, right from protecting expensive artwork to pre-purification of water to absorbing carbon dioxide. It can also be used with pharmaceutical products, since this desiccant is odourless. In addition, molecular sieves are very suitable for use in high temperature applications, with a melting point that is slightly less than 2900 degrees Fahrenheit. They are also used in chemical reactions since they are stable. However, one should always wear a dust mask and gloves while handling it, as safe as this desiccant is.

  1. The basic principle of operations starts with the wet gas entering the adsorption tower at the top which contains the molecular sieve dessicant. The gas exist the bottom of the vessel dry. While one tower is adsorbing, the other tower is regenerating. For regeneration, gas is heated up to 550 ˚F and is sent to the tower in regeneration to extract the water from the molecular sieves.
