CM <br /> WM�� <br /> 7 _-M IM"RIF <br /> GENER)LL SPECIFICATIONS <br /> The 14.11C conuists of a vacuum Punip/compre';Sor and clecLric <br /> motor, COMP10te with recycle 100P and dilution air valve and a <br /> silencer on tho intake air., a ThOx with all necosDary controls and <br /> interlocks for safe operation; a CatOx with a recuperative heat <br /> exchengor, a 5-kW olectric prehoater with thormocouplo <br /> temperature controller, and j_rtage catalyst ,jection; and weather <br /> proof instrument cabinet. <br /> Off-Plots supplied by the customer: <br /> 1 . Either natural gas or propane for tho pilot flame <br /> id enrichment fuel to the ThOx, at a pressure that shall be <br /> ecided with the cuntomer (but generally In the r4nge of 2 to 5 <br /> 2. Electric power to the unit as follows: <br /> a. 230V single phase, <br /> 25 A circuit for preheaters <br /> b. 115V, 20 A circuit for controls <br /> c. Power for VCU electric drive motor: usually 5 <br /> hp, 3-phase, or 3 hp single phase <br /> Ca4city a <br /> nd efficiency. The MMC will eperate with a <br /> destruction efficiency of ydrocarbons exceeding 90%. <br /> Higher <br /> destruction efficiencies are routine under most conditions; when, <br /> however, the combustible content of tho axtracted vent gas is low <br /> (Say below 1000 ppmv) , then it is more economical to operate at a <br /> minimum off Iciency of 901. At all times the M.Mic can mnot an <br /> altGrnative operating limit of a maximum. Sydrocarbon emission <br /> rate of 10 lb/day. <br /> Instrumentation and- controls. The MMC has local indicatin,� <br /> Instruzents, and controls sufficient for unattended operation. <br /> An option is ays12able that includes a continuous, on-line F.I.D. <br /> art recorder. <br /> This option could be expanded at modest cost to include a data <br /> ulator and telephone moden so that .(a) a central office <br /> ACCUM <br /> could obtain Xey operating and analytical data routinely, and/or <br /> an alarm wiuld be triggered in a central office if key <br /> levels were exceeded. <br /> 2 <br />
