SYSTEMS MODEL V4 U.S. PATENT 4846134 <br /> CANADIAN PATENT 1,287,805 <br /> 1.00 GENERAL <br /> It is the intent of these specifications to describe a "State of the <br /> Art" Soil Remediation and Tank Degassing System including an internal <br /> combustion engine capable of extracting hydrocarbon vapors from <br /> contaminated soil or storage tanks without the use of a compressor or <br /> pump and destruct such vapors as fuel in a controlled manner by the <br /> use of an on-board computer system. <br /> 2.00 DETAILED DFSCRIMON <br /> System shall conform to the following minimum requirements; <br /> 2.01 ENGM <br /> The engines shall be an industrial version; 2 each 460 CID Ford Model <br /> LSG-875. The engines shall be totally controlled by a single computer <br /> system described below and shall be capable of operating one week (168 <br /> hours) without need of servicing or operator. The engines shall be <br /> equipped with an automatic oil level device together with three (3) <br /> automotive type cartridge filters each. The engines serve as both a <br /> vacuum pump and as a means of destroying hydrocarbon vapors removed <br /> from the soil. Engine cooling shall be by means of an oversized <br /> radiator and zero-pressure coolant system to insure safety and long <br /> life. <br /> 2.02 FUEL CONTROL SYSTEK (Patent Pending) <br /> Supplemental fuel as may be required for proper combustion shall be <br /> either Propane (LPG) or Natural Gas. The control of the fuel to each <br /> engines shall be by the means of an electro/mechanical system including <br /> a Master Control Unit (MCU). The MCU shall adjust the supplemental fuel <br /> flow to compensate for changing influent hydrocarbon concentrations and <br /> maintain the air/fuel ratio at stoichiometric. <br /> 2.03 IGNMON SYSTEW <br /> ae ignition System shall be an electronic type, automatically adjusted <br /> by commands from the computer. <br /> 2.04 ELECTRrCAL POWER <br /> Electrical power shall be supplied by an on-board inverter system for <br /> "stand-alone" capability. Outside 120v, 60cyc power (dedicated service) <br /> • may be used as an option. <br /> V4/9/91-1 <br /> -ye vxrnr rur�nn r,nr0 AK?Ali rr\. ..r rrnnlln• -- <br />
