BF 7866 Sorbead WS
Water-resistant adsorbent, also known as KC-Trockenperlen® WS
BASF SorbeadTM WS water- resistant silica gel adsorbents have high capacity and protect other adsorbents and catalysts from water and moisture in a broad range of applications.
The patented BASF Sorbead line of highly efficient adsorbents are alumino-silicate gels in the form of hard, spherical beads, with a very high resistance to crushing and a low attrition rate. Sorbead adsorbents have a longer life than most other adsorbents and can reduce operating costs in most applications.
Sorbead WS is the only 100 % water-resistant adsorbent with a high adsorption capacity. It is most frequently used as a protective layer in combination with Sorbead R or other adsorbents such as molecular sieves, activated alumina, activated carbons and catalysts in order to increase the reliability of the system. The high capacity of Sorbead WS enables it to be used on a stand-alone basis as well. With its high resistance against hydrothermal aging and low regeneration temperature, Sorbead WS is ideal for applications where adsorbent regeneration with humid gas occurs (e.g. Heat-of-Compression and Blower-Purge air dryers, air separation plants).
