I <br /> SO L l�EC <br /> O <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 sols with volatile organic compounds (VOC's) which are <br /> present from leakage or spillage. <br /> The SCAT is most effective when the sol vapor concentration is nominally <br /> between 500 and 3,500 parts per million by volume The SCAT utilizes a <br /> catalyst cell and a 50% efficient heat exchanger to e utility <br /> consumption whle remediating the soil. <br /> ECAT GENERAL DESCRIPTION <br /> The ECAT Oxidizer is skid mounted or trader mounted and contains the <br /> • following items: <br /> Entrained Liquid Separator — Vacuum Pump & Motor — Electncal Control <br /> Panel -- Heating Elements — Oxidizer Chamber — Catalyst Cell — Heat <br /> Exchanger <br /> Soil vapors are extracted with the vacuum pump through the entrained liquid <br /> separator, which removes the majonty 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 /> utzlizmg the catalyst exhaust. Ater pre-heatmg, 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 ECAT oxidizer is described more thoroughly in the technical <br /> specification section of this document. <br /> I <br /> (0 <br /> I ` <br />
