POTASIT is a synthetic zeolite of type 3A having pore size of 0,3 nm. Molecular sieves are crystalline aluminosilicates of alkali metals or alkaline earth metals. They have a three-dimensional crystal lattice with basic structural units of SiO^-₄ and AlO^-₄ tetrahedrons so arranged, that regular alternating cavities are formed. The size of the intracrystalline cavities and of the intake opening – the pores to the cavities – are charakteristic for the individual types of molecular sieves. The molecular sieves are without toxic components.
POTASIT has 50-60 % of sodium ions exchanged by potassium ions. Its chemical composition in dehydrated state is given by the formula: K₂O . Na₂O . Al₂O₃ . 2 SiO₂.

Quality Parameters:

  RAK₄₃ – equilibrium adsorption capacity
This parameter is determining the capability of the zeolite to adsorb water vapour from air at 25°C and with 43% of relative humidity; the value is expressed as: water grams per 100 grams of anhydrous zeolite
  G 14/18 – spheres with diameter 1,4 – 1,8 mm

Application:

The product is used above all for:

	drying unsaturated hydrocarbons in dangerous or liquid phases (ethyelene, propylene, butadiene, acetylene)
	drying alcohols (methanol, ethanol)
	separation of CO from air in the production of N2 and O2
	as drying agent to insulate double – or triplex glass (windows)
	to dry polar liquid with small molecule diameter

Packaging and Storage:

Zeolites are packed and supplied in 20 litres or 200 litres packages. The maximum water content in granulated packed products is 1,5 wt.
