Table 32 to Subpart UUU of Part 63—Requirements for Performance Tests for HAP Emissions From Sulfur Recovery Units Not Subject to the New Source Performance Standards for Sulfur Oxides
As stated in § 63.1568(b)(2) and (3), you shall meet each requirement in the following table that applies to you.
For . . . You must . . . Using . . . According to these requirements . . .
1. Each new and existing sulfur recovery unit: Option 1 (Elect NSPS). Measure SO2 concentration (for an oxidation or reduction system followed by incineration) or the concentration of reduced sulfur (or SO2 if you use an instrument to convert the reduced sulfur to SO2) for a reduction control system without incineration. Data from continuous emission monitoring system. Collect SO2 monitoring data every 15 minutes for 24 consecutive operating hours. Reduce the data to 1-hour averages computed from four or more data points equally spaced over each 1-hour period.
2. Each new and existing sulfur recovery unit: Option 2 (TRS limit). a. Select sampling port's location and the number of traverse ports. Method 1 or 1A appendix A to part 60 of this chapter. Sampling sites must be located at the outlet of the control device and prior to any releases to the atmosphere.
b. Determine velocity and volumetric flow rate. Method 2, 2A, 2C, 2D, 2F, or 2G in appendix A to part 60 of this chapter, as applicable.
c. Conduct gas molecular weight analysis; obtain the oxygen concentration needed to correct the emission rate for excess air. Method 3, 3A, or 3B in appendix A to part 60 of this chapter, as applicable. Take the samples simultaneously with reduced sulfur or moisture samples.
d. Measure moisture content of the stack gas. Method 4 in appendix A to part 60 of this chapter. Make your sampling time for each Method 4 sample equal to that for 4 Method 15 samples.
e. Measure the concentration of TRS. Method 15 or 15A in appendix A to part 60 of this chapter, as applicable. If the cross-sectional area of the duct is less than 5 square meters (m2) or 54 square feet, you must use the centroid of the cross section as the sampling point. If the cross-sectional area is 5 m2 or more and the centroid is more than 1 meter (m) from the wall, your sampling point may be at a point no closer to the walls than 1 m or 39 inches. Your sampling rate must be at least 3 liters per minute or 0.10 cubic feet per minute to ensure minimum residence time for the sample inside the sample lines.
f. Calculate the SO2 equivalent for each run after correcting for moisture and oxygen. The arithmetic average of the SO2 equivalent for each sample during the run.
g. Correct the reduced sulfur samples to zero percent excess air.sa Equation 1 of § 63.1568.
h. Establish each operating limit in Table 30 of this subpart that applies to you. Data from the continuous parameter monitoring system.
i. Measure thermal incinerator: combustion zone temperature. Data from the continuous parameter monitoring system. Collect temperature monitoring data every 15 minutes during the entire period of the performance test; and determine and record the minimum hourly average temperature from all the readings.
j. Measure thermal incinerator: oxygen concentration (percent, dry basis) in the vent stream. Data from the continuous parameter monitoring system. Collect oxygen concentration (percent, dry basis) data every 15 minutes during the entire period of the performance test; and determine and record the minimum hourly average percent excess oxygen concentration.
k. If you use a continuous emission monitoring system, measure TRS concentration. Data from continuous emission monitoring system. Collect TRS data every 15 minutes for 24 consecutive operating hours. Reduce the data to 1-hour averages computed from four or more data points equally spaced over each 1-hour period.
