Mobile Dual Phase Extraction
At Talon/LPE, we have decades of combined experience in conducting MDPE services throughout Texas and have performed over 750 MDPE events in the past 5 years. This successful in-situ remedial strategy of hydrocarbon contaminated sites has spurred the utilization and growth of MDPE.
We consider this non-invasive remedial technology to be key in our toolbox of remedial options we provide. We utilize current technology and both, industry standard and site-specific remedial strategies to meet individual client site specific needs. With the ability to utilize down well ‘stingers’ or submersible pumps, and the ability to treat and dispose of extracted liquids onsite, Talon/LPE has both the expertise and equipment to meet your needs.
Enhanced Vacuum Technology Uses
Best described as High Vacuum Multiphase Extraction (HVME), this in-situ remediation process simultaneously removes multiple phases of VOC’s from both the vadose and saturated zones. It is used to enhance aerobic biodegradation when PSH has been eliminated or reduced.
This technology can be used on a multitude of different projects including: initial releases, site delineation (well installation, groundwater sampling), remediation (MDPE, bioremediation, dig & haul), sampling (groundwater and soil) site closures (Well Plugging).
Thermal Oxidation Unit (VAC)
With this unit, the recovered vapor is destroyed by a propane assisted thermal oxidizer which maintains a temperature of 1410°f. These units can generate vacuum up to 25” hg that can be applied directly to the extraction wells. These units can handle a higher flow rate of vapor phase VOC’s due to the increased destruction capacity of a thermal oxidizer.
Electric Catalytic Oxidation Unit (EC)
With this unit, the recovered vapor is destroyed by use of a platinum catalyst rather than applying direct heat as is the case for thermal oxidation units. Typical temperatures range from 500°f to 650°f. These units can generate vacuum up to 25” hg that can be applied directly to the extraction wells. These units do not require the use of supplemental propane to keep the oxidizer operating.
Benefits of MDPE
Mobile Dual Phase Extraction is cost effective, as it offers a "pay as you go" method of remediation. Furthermore, it can be utilized at any time during the "life cycle" of a site (i.e. emergency response, initial abatement, interim remediation, corrective action). This vacuum technology removes vapor, liquid and absorbed and dissolved phase VOC's simultaneously from entire soil columns from as many as five monitor wells. This technology is excellent for source removal, highly mobile and does not require utility hook ups.
