Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such as chemical bonding of water molecules. They are commonly encountered in foods to retain crispness. Industrially, desiccants are widely used to control the level of water in gas streams. [1]
Desiccation is widely employed in the oil and gas industry. These materials are obtained in a hydrated state, but the water content leads to corrosion or is incompatible with downstream processing. Removal of water is achieved by cryogenic condensation, absorption into glycols, and absorption onto desiccants such as silica gel. [1]
Dehumidifiers that work according to the absorption principle are well-suited for high humidity at low temperatures. They are often used in industry to achieve humidity levels below 35%. Because of the absence of compressor parts, desiccant dehumidifiers are often lighter and quieter than compressor dehumidifiers.
The lower compartment of the desiccator contains lumps of silica gel, freshly calcined quicklime, Drierite, molecular sieves, phosphorus pentoxide, (not as effective) anhydrous calcium chloride, or other desiccant to absorb water vapor. The substance needing desiccation is put in the upper compartment, usually on a glazed, perforated ceramic plate.
Twin Tower, or regenerative desiccant dryers, have two vertical tanks filled with media. The compressed air is passed through a pressure vessel with two "towers" filled with a media such as activated alumina, silica gel, molecular sieve or other desiccant material. This desiccant material attracts the water from the compressed air via adsorption.
What is The Pink Stuff and how does it work? Made mostly of baking soda, quartz, and soap, The Pink Stuff works as a mild abrasive that gently wears away stuck-on stains. The tiny quartz particles ...
