Molecular sieve is extensively utilized in the process of purification of petroleum products. However, these products possess powerful compounds like hydrogen sulphide, mercaptan, carbon dioxide and water which ought to be taken away to get the unadulterated product. Since, the adsorption process is done by allowing the passage of gasoline product from the cot of zeolite for some time period according the quality of impurity needed to be taken away. The contaminants found in the adsorbent are effortlessly detached away from molecular sieve in the temperature range of 200 degree Celsius to 325 degree celsius. 13x molecular sieve based upon sodium brings perfect result while sweetening of mercaptans as well as other unnecessary compounds with the aid of purifying and drying specific types of gases and liquids.

The main objective of molecular sieve is to decrease or neglect the abundant water content to fixed level. However, 13x desiccant type X crystals shape possess pore size is very large compared to type A crystal. The aspect involved in neglecting the impurities cannot be found easily with A Type crystal since 13X is employed for specific dehydration process of taking away the mercaptan odorants from gases used in aerosol industry.  Since, it can easily absorb all kinds of materials that has molecular diameter of less than 10 angstrom. The mercaptan removal process is carried out easily from aerosol, LPG, natural gas and other hydrocarbons by making use of most specific pore size of molecular sieve type. 

Molecular sieve has the capability to adsorb the typical organic chemical found in countless of liquid and gaseous application so as to get high percent of clean and pure products at the end. While for natural gas sweetening and liquid hydrocarbons, removal of mercaptans and H2S is needed in process of dehydration to obtain the clean natural gas devoid of any sort of impurities. The molecular sieve adsorbent can be employed for wide range of applications depending upon its molecular size and shape. There are various kinds of molecular sieves beads form available like 3A, 4A, 54 and 13X. Other than beads form, the molecular sieve is also found in pellets.

The molecular sieve has been considered as the strongest adsorbents which are having powerful adsorption capacity with carbon dioxide, oxygen, water and other molecules which is less compared to its pore size. Moreover, all the molecular sieve adsorbents are available in powdered, pelleted and beaded form. The molecular sieve is a wonderful crystalline alumina silicate that has the amazing ability to serve as the adsorbent to gases and solvents. It carries out the separation and adsorbing process depending upon the size of molecules. 


Industrial Use:

  • Petrochemicals
  • Chemical Refineries
  • Natural Gas Manufacturing Industry
  • Industrial Gas Manufacturing Industry

Other Industrial Applications use of Molecular Sieve 13X:

  • Treatment of liquefied natural gas (elimination of H2O, CO, H2S and mercaptans.)
  • Sweetening of natural gas
  • Drying and purification of inert gas
  • Drying and removal of CO from air before the air liquefaction units
