  2. Desiccant - Wikipedia

    en.wikipedia.org/wiki/Desiccant

    One measure of desiccant efficiency is the ratio (or percentage) of water storable in the desiccant relative to the mass of desiccant. Another measure is the residual relative humidity of the air or other fluid being dried. For drying gases, a desiccant's performance can be precisely described by the dew point of the dried product. [1]

  3. Silica gel - Wikipedia

    en.wikipedia.org/wiki/Silica_gel

    Silica gel's high specific surface area—around 750–800 m 2 /g (230,000–240,000 sq ft/oz) [6] —allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other ...

  4. Activated alumina - Wikipedia

    en.wikipedia.org/wiki/Activated_alumina

    The compound is used as a desiccant (to keep things dry by adsorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al 2 O 3). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has.

    Another important use is as a desiccant. They are often utilized in the petrochemical industry for drying gas streams. For example, in the liquid natural gas (LNG) industry, the water content of the gas needs to be reduced to less than 1 ppmv to prevent blockages caused by ice or methane clathrate.

  7. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
