SECTION 5 DBP BLOWER PURGE HEATED DRYER

5.8 EQUIPMENT SHUT DOWN
The Dryer can essentially be shut down under any
“
emergency conditions ” at any time in the cycle. It
is advisable to be fully familiar with the dryer and its
operation to avoid any possible hazard or injury as
the equipment is under pressure and may be hot.
When the system is shut down and the power
removed, the dryer bypass valve must be opened
and the outlet block valve must be closed to prevent
the vessel in adsorption becoming overloaded with
moisture.
FOR PLANNED SHUTDOWNS, IT IS
RECOMMENDED TO COMPLETE THE
REGENERATION PROCESS (HEATING AND
COOLING) PRIOR TO STOPPING THE DRYER.
This ensures that the full heating and cooling cycle
took place and that a fully regenerated bed will be
available when the system is re-started.
If a long shut down is planned it is recommended to
remove the process flow and fully regenerate both
vessels prior to shut down. The equipment should
then be left depressurized with the system inlet and
outlet block valves closed and the power removed.
To place the system in operation repeat the start up
procedure.
