B. CONTROL TECHNOLOGY
B1. MANUFACTURER/SUPPLIER:
     Siemens Westinghouse
     1007 Mansell Road
     Roswell, GA 30076
     (707) 552-8527
B2. TYPE:    Siemens, SINOx, SCR and oxidation catalyst system.
B3. DESCRIPTION:
      The add-on air pollution control equipment consists of a reactor housing with two catalyst beds.
    The first bed contains a proprietary SCR catalyst for NOx and the second bed contains an
    oxidation catalyst for CO and hydrocarbons. The subject equipment uses a feed
    forward/predictive emission monitoring system to provide emissions control during rapid load
    change periods. The system is programmed with NOx vs. engine load data during startup and
    the computer uses this information to determine the right quantity of ammonia to inject into the
    catalyst bed. In addition, the catalyst bed has a "sponge effect" feature that minimizes NOx and
    ammonia spikes by absorbing these spikes during load changes followed by gradual desorption
    thereafter. Key parameters that  affect the efficiency of the SCR/oxidation catalyst system include
    the following: operating temperature (the permit requires > 500 degrees Fahrenheit), ammonia
    flow rate to the SCR (the permit requires < 0.7 gallons/hour), residence time, engine air/fuel ratio
   (for this application, the air/fuel ratio should be 32:1 at peak load), and back pressure.

B5. WASTE AIR FLOW TO CONTROL EQUIPMENT:                                                     FLOW RATE:
      ACTUAL CONTAMINANT LOADING:                                                                      BLOWER HP: HP
B6. WARRANTY:     Equipment and components - 1 year; Process requirements - 3 years
B7. PRIMARY POLLUTANTS:
     The control equipment is used to reduce NOx, CO, and ROG emissions from the engine.
B8. SECONDARY POLLUTANTS:
      There is a small quantity of ammonia emitted from the air pollution control equipment
     (i.e., ammonia slip). Permit conditions limit the ammonia emissions to not more than 0.331 lb/hr
     and 10 ppm.
B9. SPACE REQUIREMENT:
      The subject control equipment (including ancillary equipment) requires approximately
     100 square feet of floor space with an additional 90 square feet of floor space required for
     the ammonia storage tank. The size of the control equipment is directly related to the exhaust
     gas flowrate.
B10. LIMITATIONS:
        The exhaust gas temperature should be maintained between 340-850 degrees Fahrenheit
      in order to ensure complete reaction of ammonia and NOx. Also, the SCR has been
      demonstrated with liquid and solid fuels, but not with digester gas or landfill gas.

B12. OPERATING HISTORY:
        The subject equipment has been in continuous operation since April 1996. During this period
      the engine typically operated at 80-95% capacity.

        DESTRUCTION EFFICIENCY:                                                                OVERALL EFFICIENCY:
        PERFORMANCE DATA:
      The subject engine was source tested by Air Nova, Inc. in January and March 1997. The
      source test reports have been analyzed by the New Jersey Department of Environmental
      Protection (Bureau of Technical Services) and compliance with permit limits has been
      demonstrated. In addition to the local permitting authority, the District's Source Testing &
      Engineering Section has also evaluated the complete source test report. The following data
      (corrected to District standards) provides the results from the March 1997 tests.
      Emissions Data (four 1-hour tests):
      NOx = 16.5, 13.9, 14.0, 15.6
      CO = 26.5, 25.8, 25.1, 24.8
      NH3 = <0.1, <0.1, <0.2, <0.1
      Load = 98%, 98%, 96%, 97%
      NOx, CO, and NH3 are reported as ppm @ 15% O2, dry, 1-hour average
      VOC emissions information is not included because the source test method used is not
       consistent with AQMD methods.
B14. SOURCE TEST CONDITIONS/PERFORMANCE DATA:
        Stack Emission Testing Requirements:
         (1) Three 1-hour tests in accordance with N.J.A.C. 7:27-8.4(c) for NOx, CO, VOC, and
               ammonia.
         (2) Source tests shall be conducted within plus or minus 5% of full load.
               The manufacturer of the air pollution control equipment designed the system to meet the
               permit limits during all operating conditions except startup and shutdown.

6. COMMENTS
APP. NO.:     1-96-4371
In January 1997 a NOV was issued because the engine exceeded the concentration and mass emission rate limits for VOC. The catalyst array (which had been coated with lubricating oil during startup and break-in) was then cleaned and checked and the engine was retested in March 1997. A review of the March source test indicated compliance with VOC emission limits. For this type of control equipment, regular catalyst maintenance is necessary to ensure high efficiency operation.

The maximum uncontrolled NOx, CO, and VOC emissions from the subject engine are as follows:

NOx = 5.51 lbs/hr (0.8 gram/BHP-hr)
CO = 12.42 lbs/hr (1.8 grams/BHP-hr)
VOC = 6.90 lbs/hr (1.0 gram/BHP-hr)
