Solid Desiccant Dehydration Manufacturers

Solid desiccant dehydration also known as solid bed that employs the principal of adsorption to remove water vapor. The adsorbents used include silica gel, molecular sieve, activated alumina and activated carbon. The wet gas enters into an inlet separator to insure removal of contaminants and free water. The gas stream is then directed into an adsorption tower where the water is adsorbed by the desiccant. When the adsorption tower approaches maximum loading, the gas stream is automatically switched to another tower allowing the first tower to be regenerated. It generally specified if the dew point depressions consistently greater than 80oF are required. For large volumes of high-pressure gas, liquid dehydrating systems diethylene glycol and triethylene glycol are typically more economical if dew-point depressions of 40o to 50oF are required. It has an ability to provide extremely low dew points, dehydrate very small quantities of gas at a low cost and has an insensitivity to moderate changes in gas temperature, pressure and flow rate.
