QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) |ALREADY GRADED A+
what are common desiccants? – ANSWER- activated alumina,
granular and bead type silica gel, and molecular sieves.
what are the four categories of air dryers? – ANSWERabsorption
adsorption
refrigeration
mechanical
when working on a dryer system what must you do before
performing maitenance? – ANSWER- depressurize and isolate
the complete system.
Define regeneration(reactivation) in gas and air dryer systems. –
ANSWER- term used for the process of removing the
accumulation of moisture from the dryer bed.<\/p>\n\n\n\n
2 | P a g e
what percent of dry air is used to regenerate a dryer bed? –
ANSWER- 10-15%
Describe the operation of an absorption dryer – ANSWERabsorption dryers use a chemical bond between the drying agent
and the gas stream being dried. Its different from a adsorption
dryer in that there is no film foundation. moisture is absorbed by
the absorption material and forms a solution.
Describe a chemical dryer also known as a solid dehydration
dryer. – ANSWER- this type of dryer cannot be regenerated,
must use deliquescents, which slowly dissolve or melt away as
they combine with the moisture they are absorbing, because of
this the bed must be replenished periodically because the
deliquescent is consumed by the drying process.
Describe liquid Dehydration – ANSWER- an absorbing
agent(ethylene glycol) is used to remove moisture, gas is
brought into contact with agent being sprayed through nozzels.
Describe Refrigeration dryers. – ANSWER- least expensive
method of dew point reduction, this is because there are no
absorption or absorption materials that require maintenace or
replacement. by cooling air in an aftercooler the air is less able
to hold moisture, so water can drop out of the stream and be
removed.<\/p>\n\n\n\n

In a Refrigerant circuit in a refrigeration dryer what happens to
the water? – ANSWER- because water freezes at 0C(32F) the
condensed water would freeze in this dryer if the controls were
set too cool the air too much. This type of dryer is capable of
lowering the dew point to 2 to 3 degrees celcius. lower temps
would cause it to freeze.
Describe Mechanical dryers. – ANSWER- use only mechanical,
physical means to cause moisture to fall out of the air stream.
these include devices that use intertia or mechanical
components, such as barriers and filters.
Define Liquid seperators – ANSWER- air enters a large vessel,
the reduction in velocity by the size of the dryer and the baffles
inside allows contaminants such as sand,oil,acids and other
liquids to slow down and drop to the bottom of the vessel where
they can be removed
Define a Centrifugal Separators – ANSWER- found downstream
of compressor aftercoolers the centrifugal separator uses
centrifugal force to throw incoming air or gas outwards causing
the heavy particles to drop to the bottom and be removed.
