Molecular Sieve for Mercaptan Removal
Mercapran Removal
Molecular sieve is widely used for the purification process of petroleum products. These products have strong compounds such as water, carbon dioxide, hydrogen sulphide and mercaptan that need to be removed to obtain the pure product. The adsorption process is carried out by passing the petroleum product from the bed of zeolite for the specific period of time depending on the amount of impurity required to be removed. The adsorbed contaminants can be easily removed from the molecular sieve at a certain temperature range i.e. from 200 °C and 325 °C. The sodium based Type 13X molecular sieve brings excellent outcome when removing mercaptan and other unwanted compounds with the help of drying and purifying certain types of liquids and gases.

The main purpose of molecular sieve is to reduce or eliminate the water content to the predetermined level. 13X desiccants contain Type X crystal structure and also has much larger pore size than the Type A crystals. The feature of removing the impurities that cannot be possible with Type A crystal, 13X is used for the desired dehydration process of removing the Mercaptan. It can adsorb all types of materials which have less than 10 angstrom molecular diameter. Mercaptan removal is done from natural gas, LPG and various other liquid hydrocarbons using the most appropriate pore size of the sieve type.

This adsorbent has the ability to trap the typical mercaptans in number of gaseous or liquid applications to obtain high percentage of pure and clean products. In case of liquid hydrocarbon and natural gas sweetening, removal of H2S and mercaptan is required in the dehydration process to get the clean natural gas without any kind of impurities.


  • Natural gas sweetening
  • Liquid hydrocarbon streams (LPG, butane etc)
  • Oil refining applications
