DRYER DESICCANTS

With more than 65 years of experience developing desiccant formulas, Van Air Systems is the original and leading manufacturer of deliquescent desiccants for drying compressed air and gases. From a definition standpoint, a desiccant is a hygroscopic substance used as a drying agent. Many are commonly encountered in packaging to keep the contents dry and free from mold or mildew. However, for many industrial uses, deliquescent desiccants are a dependable, cost-effective, and energy-free tool for a wide range of industrial drying applications. Van Air Systems offers a variety of adsorbent desiccants, including activated alumina, silica gel, and molecular sieve. These desiccants are used in point-of-use applications, as well as in regenerative drying applications.

DRYER DESICCANTS - 10BF

10BF is the most effective deliquescent desiccant from Van Air Systems. Formulated primarily for the dehydration of natural gas and for use in Van Air Systems Pipeline Dryers, 10BF is a dense hygroscopic tablet that absorbs water vapor. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolve, or deliquesces, until the desiccant is fully consumed. Van Air Systems deliquescent desiccants, including 10BF, are non-toxic and fully water soluble. In a properly sized Pipeline Dryer, 10BF will establish a relative humidity of 13%, which equates to a dew point depression of approximately 50-60°F.

Features & Benefits

For operative temperatures 100°F and lower
Cam be used to replace TEG systems
Prevents air and gas line freeze-ups
Up to a 63 degree dew point suppression
Up to a 13% equilibrium RH

Applications

Meets pipeline gas moisture specifications
Fuel gas & biogas dehydration
Instrument gas dehydration
Sales gas dehydration
Remote outdoor locations without electricity

DRYER DESICCANTS - 4UF

Natural gas or process gas dehydration at low pressures, low flow rates, and / or low temperatures can be very difficult. Most conventional salt-type absorbent desiccants are unable to adequately dry gas to low water content under these conditions. 4UF was developed to meet low dew point requirements when other desiccants or glycols cannot. 4UF can be used by itself or in combination with other grades of deliquescent desiccant, such as SP or 10BF Desiccant. In some applications, consumption is optimized when the process gas flows through the lower grade desiccant prior to the highly absorbent 4UF.

Features & Benefits

7 lbs H20 . MMSCF gas is attainable @ 50 PSIG & 60°F
20 lbs H20 / MMSCF gas is attainable @ 25 PSIG & 80°F
Used when gas line temperatures are below freezing
Up to a 4% equilibrium RH

Applications

Meets pipeline gas moisture specifications
Fuel gas & biogas dehydration
Lowers moisture content of biogas
Instrument gas dehydration
Remote outdoor locations without electricity

DRYER DESICCANTS - DRY-O-LITE

Dry-O-Lite, the industry-leading deliquescent desiccant, is a chemical drying agent specifically formulated for Van Air Systems single tower compressed air dryers and natural gas pipeline dryers. Dry-O-Lite is a dense hygroscopic tablet that absorbs water vapor from streams of compressed air or gas. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed. In a properly sized D-series Compressed Air Dryer or Pipeline Dryer, Dry-O-Lite will establish a relative humidity of 55%, which equates to a dew point approximately 20°F lower than the temperature of the compressed air or gas at the inlet of the dryer.

Features & Benefits

Up to 20 degrees dew point suppression
Low cost
Energy free
Environmentally friendly
Up to a 55% equilibrium RH

Applications

Industrial plant air
Abrasive blasting & painting
Portable air drying
Ready-mix & concrete plants
Wood products

DRYER DESICCANTS - ACTIVATED ALUMINA

Activated alumina is an aluminum oxide bead with an extremely porous structure and high surface area-to-mass ratio. Activated alumina has a wide variety of applications, including compressed air and gas drying. In compressed air and gas drying applications, activated alumina will achieve dew points -40°F to -100°F, depending on the dryer design. In compressed air desiccant dryers, a 1/8″ (2-5 mm) activated alumina bead is most commonly used. The 1/4″ (5-10 mm) activated alumina bead is typically used as a pre-bed for supporting large desiccant beds or as a buffer for silica gel beds. The 3/16″ (5-10 mm) bead is used when pressure drop and surface area requirements fall between the 1/8″ and 1/4″ material.

Features & Benefits

Low to zero dust discharge
High adsorption capacity
Low abrasion
High crush strength

Applications

Regenerative dryers
Acid removal
Process stream purification
Hydrocarbon adsorption

DRYER DESICCANTS - SPECIAL PURPOSE “SP”

SP is a leading deliquescent desiccant formulated primarily for the dehydration of natural gas for use in Van Air Systems Pipeline Dryers when the gas temperature is below 80°F. SP is a dense hygroscopic tablet that absorbs water vapor. The surface of the desiccant tablet dissolves slowly, forming a brine solution which drops from the surface. The tablet continuously dissolves, or deliquesces, until the desiccant is fully consumed. Van Air Systems deliquescent desiccants, including SP, are non-toxic and fully water soluble. In a properly sized Pipeline Dryer, SP will establish a relative humidity of 33%, which equates to a dew point approximately 30°F lower than the temperature of the gas at the inlet of the dryer.
