Calsit

Usage

  • to dry gases and liquids
  • to remove CO2, H2S, mercaptans from gases
  • to remove CO2, CO, H2S, CS2 and hydrocarbons from air for liquefying and rectification
  • to purify oxygen and for air separation at PSA process
  • to dry and purify the natural gas
  • for separation of n-alkanes by adsorption from branched and cyclic hydrocarbons in gaseous and liquid phase
  • as adsorbent in the gas chromatography
  • as packing at the cryosorption vacuum pumps
  • for purification and drying protective atmospheres of synthesis gases, gaseous and liquid hydrocarbons, rare gases, Na2O and hydrogen

General characteristics

Calsit is a synthetic type 5A zeolite with pores size 0.5 nm. The molecular sieves are crystalline aluminosilicates of alkali metals or alkaline earth metals. They have a 3-D crystal lattice with tetrahedrons SiO4 and AlO4 as its basic components, arranged to create a regularly alternating cavities. The dimensions of intra-crystalline cavities and entering pores into cavities are characteristic for the individual types of molecular sieves. The molecular sieves are free of toxic documents.

Calsit has 70 – 80% of sodium ions replaced by the calcium ions. Its chemical composition at dehydrated state expresses the formula CaO. Na2O . Al2O3 . 2 SiO2.

Packaging

The zeolites are packaged and delivered in metallic 20-liter- or 200-liter-containers. The water content in granulated packaged products is not more than 1.5 mass-%.

The guarantee period lasts 2 years from the date of production.
