Explain how to regenerate the desiccant dryer.

What will be an ideal response?


A desiccant dryer is used to remove moisture from compressor gases as they are passed over a chemical desiccant, which absorbs the water. The desiccant removes moisture from the compressed air. Only one dryer at a time is ever placed in service. Dryer 101 is equipped with a copper coil steam tracing designed to heat the dryer, vaporizing the moisture, and drying out the desiccant so it can be re-used. PIC-100 controls the pressure on the system by venting excess pressure back into the suction line. PCV-110 is a back-pressure regulator designed to reduce the 100 psig found at the instrument air header to a usable 20 psig for 3-15 psig valve actuator operation.
