Mobile Dual Phase Extraction
At Talon/LPE, we bring decades of experience in delivering Multi-Phase Extraction (MDPE) services across the South Central United States. This in-situ remediation method has proven highly effective in treating hydrocarbon-contaminated sites, driving the expansion and adoption of MDPE technology. Talon/LPE offers a range of technologies and flexible durations, tailored to meet the specific needs of your site.
We consider this non-invasive technology a key component in our range of remediation solutions. By integrating the latest advancements and employing both industry-standard and customized strategies, we address the unique needs of each client’s site. Our approach includes the use of down-well ‘stingers’ or submersible pumps, allowing us to accelerate the removal of environmentally affected fluids.
Enhanced Vacuum Technology
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 enhancing aerobic biodegradation within the subsurface.
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). This technology is also suited for a wide variety of industries including: Petroleum Refineries, Pipelines, Chemical Manufacturing Facilities, Manufacturing Plans, Retail Gasoline Stations, and Bulk Fueling Stations.
Thermal Oxidation Unit (VAC)
With these units, 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 generate high flow rates with our large volume rotary – claw blower and process a higher flow of vapor phase VOC’s due to the increased destruction capacity of the thermal oxidizer.
Electric Catalytic Oxidation Unit (EC)
With these units, 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.
Internal Combustion Engine Unit (ICE)
With these units, the extracted vapors are consumed by the engine during the normal combustion process, eliminating the need for alternative power sources. The ICE remediation trailers generate vacuum through the engine, which pulls from the stingers installed in the recovery wells. These units are equipped with automated moisture separators and controllers, ensuring efficient dual-phase recovery of both liquid and vapor while maintaining strict emissions controls. Operating at 1800-2200 rpms, the trailers maintain off-gas emissions for volatile organic compounds (VOCs) below 1 lb. per event.
Benefits of MDPE
MDPE is a cost-effective remediation method, offering a "pay as you go" approach that can be implemented at any stage of a site's life cycle—whether for emergency response, initial abatement, interim remediation, or corrective action. This vacuum technology simultaneously removes vapor, liquid, and dissolved phase VOCs across multiple sources and media, targeting up to eight monitor wells at once. Its high mobility and effectiveness in source removal make it an ideal solution, without the need for stationary systems or utility hookups.
