DULEX™
MULTIPHASE EXTRACTION SYSTEM
DULEX™ Multiphase Extraction
System
ERE’s Dulex™ Multiphase Extraction Technology is a
system that can extract Hydrocarbon Contaminants
(LNAPL), Groundwater to create a cone of depression
which will influence and contain migrating hydrocarbons to the extracted well and Volatile Organic
Compounds (VOC’s), all from one well! With one
system you can extract from one or multiple wells at the
same time and reduce your site remediation clean up
time by half or less time than traditional pump & treat
systems.

OPERATION
ERE Dulex Multiphase high vacuum is applied to an
extraction tube placed down an extraction well, below
the static groundwater table, with the bottom end of the
tube at the elevation in which draw down is desired.
The top of the well casing is sealed to atmosphere. The
vacuum applied to the wellhead then begins to extract
the groundwater from the well until the well is drawn
down and the water surface in the well reaches the
bottom of the extraction tube. At this point, the tube
"breaks suction" and begins to apply the vacuum to the
air space in the well and surrounding soil. As
additional groundwater flows into the well, it is sucked
up by the extraction tube until it again breaks suction.
This process then continues indefinitely, with alternating slugs of groundwater, hydrocarbons and vapors
pulled up the extraction tube, out of the well and into
the process equipment. The extracted vapors and
groundwater then flow through piping from the well to
ERE TORNADO™ Cyclonic Air/ Liquid Separator.
There, the liquids, groundwater and product are
separated from the vapors by cyclonic action.
Oil/Water Separators such as ERE’s Olio-Sep™ are
used to separate the two phases allowing hydrocarbons to be captured in a storage recovery tank. The
effluent proceeds into other means of treatment such as
ERE V.O.Cease™ Air Stirpper and/or conventional
carbon treatment methods such as ERE’s vast line of
UltraSorbers™. Once contaminants are separated,
filtered and/or treated, the clean water can then be
recharged into the ground or discharged to the surface
water body or municipal sewage plant. The contaminated vapor continue on into the High Vac Pump. It is
then discharged, under pressure, out of the High Vac
Pump, and into the atmosphere. Secondary treatment
of vapors may be added. Contact your Local Environmental Regulatory Agency for permit requirements.
The typical limit for dual extraction is from wells less
than 25' deep. Extraction from deeper wells is
possible, but requires some additional fittings. Most
systems utilize a High Vacuum Pump as the vacuum
source because they can achieve the high levels of
vacuum required, typically 18-22 inches of mercury.
ERE Dulex Multiphase Extraction Technology has been
successfully implemented in well up to 55 ft in depth
without significant modifications in wellhead design.
