Silica Gel Adsorbent Desiccant
 |
Van Gas Technologies silica gel adsorbent desiccant beads consist of 97% silicon dioxide and 3% alumina. The bead shape, uniform particle size and high bulk density of this dry bed desiccant combine to ensure optimum gas flow without channeling. Also, minimal dusting occurs within the tower of the dryer due to the physical characteristics of this adsorbent desiccant. An immense network of inter-connecting microscopic pores exists within a single granule of silica gel. This network of pores attracts and retains moisture via physical adsorption and capillary condensation. Even once the silica gel adsorbent desiccant has become completely saturated, the beads appear to be and feel dry to the touch. Van Gas silica gel will fracture in the presence of liquid water. Therefore, it must be protected by a 10% to 15% pre-bed of activated alumina dry bed desiccant on the inlet side of the desiccant bed. This layer of activated alumina desiccant will act as a water buffer between the natural gas dryer inlet and the silica gel adsorbent desiccant. Van Gas silica gel is available in two variations; indicating and non-indicating. Dew Points to -40° F and lower may be achieved with silica gel adsorbent desiccant depending on the gas dryer design and operating conditions.
