31604.DSK . <br /> WP-SFO <br /> 2. Automatically shut down the engine and alert the auto-dialer (supplied <br /> with vapor extraction system) if oil pressure is low, fuel supply is <br /> low, or coolant temperature is high. <br /> 3. Engine system shall operate continuously for up to 2 weeks without <br /> maintenance or delivery of supplemental fuel. During continuous <br /> operation, the engine exhaust temperature shall be consistently high <br /> enough for 99.9 percent THP destruction with:a vapor concentration <br /> of between 500 and 10,000 ppmv TPH at the well head. <br /> 4. The engine power output rating shall not exceed 50 horse when <br /> l <br /> operating ower <br /> p n <br /> ating at the design peak air flow of 100 scfm. <br /> 2.4 DESIGN REQUIREMENTS <br /> A. Control panel shall have the following gauges: <br /> 1. extracted vapor flow rate and vacuum <br /> 2. coolant temperature <br /> 3. oil pressure <br /> 4. rpm <br /> 5. hours of operation <br /> 6. alternator voltage <br /> 7. exhaust temperature <br /> 8. master shutdown/ignition switch with a key <br /> B. The influent and effluent pipes shall have 2-inch flanges. Engine exhaust <br /> shall be discharged out the top of a 15-foot-tall stackequipped with a <br /> flapper to prevent intrusion of rain. The frame shall include a hook for <br /> loading and unloading if the engine system is skid-mounted. For a �. <br /> trailer-mounted unit, the trailer shall be equipped with leveling jacks and a <br /> removable hitch. <br /> I <br /> C. The system shall be supplied with a spring-loaded, automatic vacuum relief { <br /> valve on the vapor/air intake to the engine to relieve vacuum by adding <br /> dilution air. <br /> D. Flow meters shall be provided at the locations shown on the Drawings. <br /> Flow meters shall be of the rotameter type with a range of 10 to 100 cubic <br /> feet per minute. <br /> E. Power and Controls: <br /> 1. The System Supplier shall be responsible for all wiring and controls <br /> internal to the engine system. <br /> 2. All control and operating equipment shall operate at low voltage <br /> (12V dc). <br /> 3. The system shall have an automatic controller for air-to-fuel ratio (for <br /> supplemental fuel). <br /> F. The system shall be equipped with a fire extinguisher and locking control <br /> panel door. <br /> 1 <br /> BAE31604.AS.T1 <br /> 13004 3 INTERNAL COMBUSTION <br /> ENGINE SYSTEM f <br />
