Patent
·
OSTI ID:6812599
An improved drying system is described for removing moisture from air and like gases used in pneumatic systems to produce a product gas having a dew point of -40 to about -100 degrees Fehrenheit, which comprises: a heat exchange means having an inlet for receiving inlet gas from the pneumatic systems, and an outlet, for cooling the inlet gas to produce an outlet gas having a dew point of about 35 to 40 degrees F, the heat exchange means having a refrigerant flowing; a refrigerant system connected to the heat exchange means for supplying the refrigerant to the heat exchanger means, the refrigerant system having at least a compressor; a moisture separator means connected to the outlet of the heat exchanger means for removing condensed moisture contained in the cooled outlet gas; a moisture sorption means having at least one bed of moisture removal material, the sorption means having an inlet connected to the separator to receive gas having the condensed moisture removed, and an outlet for the removal of dried gas; and a purge system for selectively removing moisture from the bed of moisture removal material.
