A summary of the cost effectiveness of innovative off-gas treatment technologies
- Los Alamos National Lab., NM (United States)
The following seven innovative treatment methods have been identified by the US Department of Energy`s (DOE) Office of Technology Development as demonstrating tangible success in the destruction and/or recovery of volatile organic compounds (VOCs) in the off-gas produced by a soil vapor extraction (SVE) system: (1) Gas-Phase Corona Reactor; (2) Silent Discharge Plasma; (3) Ozone-Enhanced Oxidation; (4) Photocatalytic Oxidation; (5) Thermatrix Padre{trademark} Regenerative Adsorbent System; (6) Brayton Cycle Solvent Recovery Heat Pump; and (7) Thermatrix{trademark} Flameless Thermal Oxidation. Life-cycle cost data for these innovative technologies were compared with those of three baseline treatment methods for controlling VOCs: Granular Activated Carbon, Thermal Oxidation, and Thermal Catalytic Oxidation. A sensitivity analysis was performed showing the dependence of cost on influent VOC concentration, inlet air flow rate, and duration of remedial action. For ease of comparison, and to illustrate how similar treatment methodologies responded to changes in input parameters, both baseline and innovative technologies were further grouped into three primary categories according to their functional processes: thermal, adsorption, and free radical technologies. Results of cost analysis indicated that the size of the treatment system in terms of the inlet air flow rate was the largest single determinant of system capital cost. However, as the duration of treatment increased, the capital cost became a less significant cost parameter than the system operational cost.
