As the industry leader in deliquescent desiccant technology, Van Air designed the PLD to be an economical and effective solution for gas dehydration. Operation of the PLD is simple. Wet gas enters the bottom of the vessel where gas velocity is reduced and flow direction is changed. In this area, heavier drops of entrained water are separated and fall into the large capacity claim area. The gas then moves upward through the bed of deliquescent desiccant tablets, which slowly dissolve as they adsorb moisture vapor.

Van Air HLSX regenerative desiccant dryers deliver extremely dry gas for critical applications and for preventing hydrate formation or freeze-ups in the harshest operating environments. Designed for natural gas service or compressed air applications in hazardous areas, all electrical controls on HLSX dryers are explosion-proof. Additionally, HLSX fittings, seals and valves have been designed for superior performance in gas service.

Landfill gas and biogas are generated during the anaerobic decomposition of organic matter, typically consisting of 60% methane and 40% carbon dioxide. Contaminant constituents often include sulfur dioxide, siloxanes and water vapor.

Historically these gases have been treated as waste by-products, being either flared or exhausted into the atmosphere.
