3 SOLLECO <br /> ECAT 250 ELECTRIC CATALYTIC OXIDIZER <br /> WITH 250 CFM VAPOR EXTRACTION PACKAGE <br /> GENERAL INFORMATION FOR THE 250 ECAT <br /> The Electric Catalytic Oxidizer (SCAT) with Vapor Extraction is used for <br /> the remediation of soils with volatile organic compounds (VOC's) which are <br /> present from leakage or spillage. <br /> The SCAT is most effective when the soil vapor concentration is nominally <br /> between 500 and 3,500 parts per million by volume. The ECAT utilizes a <br /> catalyst cell and a 50% efficient heat exchanger to minimize utility <br /> consumption while remediating the soil. <br /> ECAT GENERAL DESCRIPTION <br /> The SCAT Oxidizer is skid mounted or trailer mounted and contains the <br /> following items: <br /> Entrained Liquid Separator — Vacuum Pump & Motor — Electrical Control <br /> Panel — Heating Elements — Oxidizer Chamber — CataIyst Cell — Heat <br /> Exchanger. <br /> Soil vapors are extracted with the vacuum pump through the entrained liquid <br /> separator, which removes the majority of the water brought up from the soil <br /> during the vacuum extraction process. Dilution air is added if necessary and <br /> the vapors are pushed through the heat exchanger where they are heated <br /> utilizing the catalyst exhaust. After pre-heating, the vapors proceed to the <br /> oxidizer chamber where the electric elements heat the vapors to their final <br /> catalyst inlet temperature of 650° F. The vapors come into contact with the <br /> catalyst at 650° F and combust into water vapor and carbon dioxide. The <br /> destruction efficiency for the standard ECAT is 95% or above. <br /> The SCAT oxidizer is described more thoroughly in the technical <br /> specification section of this document. <br />
