Research output: Contribution to conferencePaper


The purpose of this analysis is to compare the cost of solar waste detoxification processes with conventional alternatives for the treatment of trichloroethylene (TCE) in air. The solar processes that were evaluated are high flux photothermal oxidation (PHOTOX), high flux thermal catalytic reforming (SOL TOX), and low flux photocatalytic oxidation (PHOCA T). The high flux processes, PHOTO X andSOL TOX, were based on dish concentrator technology. The low flux photocatalytic process was based on parabolic trough concentrating technology. The conventional alternatives are thermal oxidation, thermal catalytic oxidation, off-site carbon regeneration, and on-site solvent recovery. Analysis of the seven processes showed PHOCA T to be the most economical treatment method. PHOTO X showedslightly better economics relative to SOL TOX. Both were competitive, with the best conventional destruction process, thermal oxidation. Off-site carbon regeneration was the most expensive treatment method.
