Membrane System for the Recovery of Volatile Organic Compounds from Remediation Off-Gases. Innovative Technology Summary Report
Membrane Technology and Research, Inc.'s (MTR's) membrane-based off-gas treatment technology separates the organic components from the off-gas stream, producing a VOC-free air stream that can be discharged or recycled to the gas-generating process. The membrane system produces a constant, high-quality air discharge stream irrespective of the feed-air composition. The system also produces a concentrated liquid VOC stream for disposal. Any water vapor present in the off-gas is removed as condensed dischargeable water. Benefits: Applicable to a broad range of off-gas generating sources. Target streams are off-gas from soil remediation by in situ vacuum extraction or air and steam sparging, and soil vitrification Suitable for remote sites: systems require minimal site preparation, little operator attention once installed, electrical power but no other utilities, and no expendable chemicals Minimizes waste volume: dischargeable air and water are produced, and VOCs removed from the feed gas ar e concentrated into a condensed liquid. No other waste streams result Treats off-gases containing both flammable and nonflammable and chlorinated and nonchlorinated VOCs Cost competitive with other technologies in the VOC concentration range 100-1,000 ppm and offers significant cost reduction at higher VOC concentrations Systems are easily moved and transported to new sites with a minimum of refurbishing or modification Generates no air emissions, minimizing permitting issues and speeding up the start of a clean-up operation Technology: Removal of VOCs from air streams with membranes is a relatively new technology.
