Mobile Multi-Phase Extraction (MPE)

Drawing upon the extensive experiences gained during successful installation and operation of numerous fixed based remediation systems, Georgia Oilmen’s Services, Inc. (GOS) created Georgia Remediation Services, LLC. (GRS) to offer mobile remediation capabilities to industry and consultants. GRS is a wholly owned subsidiary formed by GOS in 2006. 
 
GRS operates a mobile multi-phase extraction (MPE) and thermal oxidation unit that can provide a variety of services. 

• MPE operation involves the extraction of subsurface vapors and liquids from a monitoring well(s) through a high-pressure vacuum system.
• Multiple mobile MPE events can provide for interim free product abatement measures, and may be a cost effective alternative to installing and operating a full scale remediation system for a short period of time. 
• MPE can be used for removal of large quantities of contaminated groundwater.
• Pilot testing data required for remediation system design can be complied during a MPE event. 
• Parameters including depth to water, influent organic vapor analysis (OVA), combustion temperature, wellhead vacuum, flow rate, vacuum radius of influence (ROI), and water table drawdown measurements are collected during each MPE event.  These parameters are presented within a report including influent concentrations and calculations of recovery rates.

 
Technical Specifications of GRS mobile MPE unit are as follows:
 

• 2 - Reitschle Zephyr VLR400 Rotary Claw pumps powered by 10 HP, 230/460/3/60 volt TEFC motors. 
• Actual flow is 500 ACFM @ 15”Hg and 480 ACFM @ 22” Hg. 
• Influent free product, petroleum contact water and vapors enter the system through a five port manifold before entering a 120 gallon phase separator equipped with level switches. 
• All liquids are transferred into a 500 gallon polyethylene holding tank also equipped with high & low level switches. 
• Liquids can then be transferred into a 2,000 gallon holding tank mounted on the transport truck.
• All liquids recovered are disposed of at a licensed wastewater recycling facility. 
• Vapors enter a 500 CFM thermal oxidizer that operates between 1,400 to 1,700^oF, ensuring 99.9 % vapor destruction. 
• All of these components are powered by a propane fueled generator. 
• The system is equipped with interlocks to ensure safe operation at all times, and a cellular autodialer alerts GRS personnel of any shutdowns.

 
GRS is committed to working with our clients to provide the ideal plan for MPE operation to fit individual project needs.  If you have a need for MPE services or would like additional information, please call Kurt Hausner or Mark Faas at (678) 225-4558.
