Split Flow - No Purge Loss Compressed Air Dryer

The wet Air / Gas stream is split at the air dryer inlet through a differential distributor valve. Part of this air / gas stream is passed through an external heater and heated to a regeneration temperature of 160-180°C, then it is fed to the Adsorber desiccant tower A containing Silica gel or activated Alumina / Molecular Sieves under regeneration thus removing out the moisture from the desiccant bed.

A water cooled / air cooled aftercooler condenses the desorbed moisture which is discharged regularly through the automatic drain trap . after condensation This Air/ Gas stream joins the main incoming air stream and goes for drying to the other tower B under drying.

Normally a Cycle time of 8+8 hrs is utilized to complete one cycle of operation. After each operation the changeover is effected automatically.

This type of dryer provides an outlet Dew Point of -40 deg C. The Air dryer can be supplied with standard accessarie like simplex / duplex Prefilters / Afterfilters, Flowmeters, dew point meters etc. The system is fully automatic / semi automatic , with Timer / PLC controls with feedbeck to/ from main DCS.

APPLICATIONS --

- Instrument air dryers for power plants Refineries & Petrochemicals , chemical & fertilizer plantsetc.

- CNG Compressed Natural Gas Drying & conditioning plants , Gas Drayers.

- Hydrogen Gas Drier for generator Cooling Application.
