Our Air Dry GasMaster 21900NG high-pressure natural gas dryer is a fully automated, heat reactivated, twin tower desiccant dryer designed to provide dehydration and purification of high-pressure natural gas at a maximum stated flow rate of 250 SCFM at 400 psig. The dehydrator provides high levels of dryness by using filters and desiccant beds.
The GasMaster dries natural gas from an inlet condition of 7 lbs./MMSCF to 0.5 lbs./MMSCF (at flow and pressure). The unit uses a programmable logic controller to automatically control every function of operation, with gas path components made of stainless steel or other corrosion-resistant materials. Pressure vessels meet ASME pressure vessel code with a safety factor of 4.0. To minimize external support requirements, the GasMaster system purge is accomplished with internally controlled dry natural gas from the main flow downstream from the unit.
