The dryer has controls and a system of valves that will switch towers on a regular basis without interrupting the flow of compressed air with molecular sieve.
Refrigerated air dryers can remove the water vapor from the compressed air, resulting in a dew point at system pressure of about 35 to 40 degrees F, which is adequate for most end uses inside a heated plant. But if the pipes are subject to temperatures below this dew point, water will condense or freeze inside the pipes. Therefore, lower dew points
Consider, as an example, a large desiccant air dryer recently found in a fertilizer plant during a compressed air audit. The specifications for the dryer with molecular sieve desiccant stated that typical compressed air consumption for cooling air purge should have been 2% of the compressed air flow through the dryer. But when measurements were tak
While on the topic of filtration I would like to interject my personal opinion that a heated type regenerative dryer should NOT be used with lubricated type air compressors with molecular sieve.
The primary design of the HOC Dryer with molecular sieve directs all the discharged air from the compressor to the HOC Dryer with molecular sieve . When using an HOC Dryer with molecular sieve , the compressor after-cooler is not used. Remember, we need the high temperature air for regeneration.
The trade off here is the blower consumes additional electricity but is decidedly more efficient than the air compressor itself. This also allows all of the compressed air to be utilized by the plant as none is required for Dryer with 4A zeolite regeneration.
Advantages of Externally Heated Regenerative Desiccant Type Dryers 4A molecular sieve include: Low dew points can be achieved without potential freeze-up. Activated Alumina desiccant 4A molecular sieve
In the internal type, heaters are embedded in the molecular sieve bed. This reduces the amount of purge air required for regeneration to less than 10%. The purge air plus radiant heat is used to regenerate the off line molecular sieve bed.
There are several different types of heat reactivated regenerative dryers with molecular sieve desiccant and below we discuss each type along with their advantages and disadvantages. In all heated type regenerative dryers with molecular sieve desiccant the heat source can be provided by either electric or steam with the most common being electric.
Other variations for standard pressure/temperature conditions are 14.7 psia and 32F. As such, these variations can cause confusion and result in a mis-match between the compressed air with Molecular Sieve supply and compressed air with Molecular Sieve demand.
The dryers work by adsorbing moisture on desiccant material such as alumina, silica gel molecular sieves. The desiccant material is contained in two packed towers which are alternately in service or being regenerated.
Although this technology can also be applied to the lower capacity range, the fact that thermal mass dryers with molecular sieve are already an excellent solution in this area means that the greater capacity range is expected to be the primary focus of development efforts.
