DESCRIPTION

Natural gas dehydration at low pressures and low flow rates can be very difficult. Most conventional salt-type desiccants are unable to adequately dry gas under very low pressure (<75psi) or when stringent pipeline specifications (>7 lbs. H2O/MMCF) must be met.

DESI-DRI E was developed to meet dew points where other desiccants or glycols can not.

DESI-DRI E can be used by itself or in combination with other grades of desiccant, such as DESI-DRI C and DESI-DRI HPA. In this application the natural gas flows through the DESI-DRI HPA or C first removing the majority of the moisture and then through the DESI-DRI E to further reduce dew points.

FEATURES

DESI-DRI E tables have several advantages over the low pressure gas drying options.

7lb/MMCF attainable @ 50psi and 60ºF

20lb/MMCF attainable @ 25psi and 80ºF

Dryer gas for less cost than glycol towers in many instances.

Greater hygroscopicity means more H2O removed per pound of desiccant.

Hard dense tablets resist caking, channeling, blooming and dusting.
