24、sents hazardous air pollutant (HAP) and volatile organic compound (VOC) emission test results from gasoline loading operations at bulk gasoline terminals. These tests were conducted for the American Petroleum Institute (MI) to provide more accurate HAI? emission estimates from bulk gasoline terminal
25、s employing emissions control equipment. Current procedures typically assume that control efficiencies for HAPS are equal to the control efficiencies for total VC. For this study, MI sponsored HAP emission testing at 33 buk gasoline terminals around the United States. Each test measured emissions fr
26、om facilities with a vapor control system. Emission tests from 23 carbon adsorption units (with VOC emission factors ranging from 0.7 to 70 milligrams of VOC/liter gasoline loaded), eight thermal oxidizers, and two refrigeration units were included. Control efficiencies for eight HAP compounds were
27、derived for carbon adsorption units and thermal oxidizers (no control efficiencies are reported from the refrigeration units due to the limited data collected). Table ES-1 summarizes the average control efficiencies found in this study. The results from the carbon adsorption units indicate that cont
28、rol efficiencies for HAPs average over 99% and are insensitive to the total VOC control efficiency of the treatment unit. This is observed even at VOC control efficiencies below 90%. These conclusions are illustrated in Figure ES-1. The limited data from the thermal oxidizer emission tests indicate
29、that the control efficiencies for HAPs are similar to the control efficiencies for total VOCs. Finally, the HAP control efficiencies presented in this report have been used to develop HAP emission factors. Derivation of these emission factors is dependent on facility operation parameters (e.g., vapo
30、r balancing, bottom loading) and gasoline speciation characterization (i.e., HAP content in gasoline). These HAP emission factors can be used to determine HAP emissions based on the volume of gasoline loaded at a facility. ES-1 STD.API/PETRO PUBL 347-ENGL 1998 W 0732290 Ob11873 698 Total VOC 97.30 8

35、s (VOCs) and volatile organic hazardous air pollutants (HAPs) from gasoline loading operations at bulk gasoline terminals. The results of these emission tests have been used to develop new controlled emission factors for HAPs at bulk gasoline terminals. In developing the emission factors presented i
36、n this report, API followed the most recent EPA procedures for preparing AP-42 emission factors PA, 1992). In preparing this report, NI followed the suggestions for submitting emission factors to EPA as outlined in the draft report “Public Participation Procedures for EPAs Emissions Estimation Guida
37、nce Materials” PA, 1994). During the development of the Gasoline Distribution National Emission Standards for Hazardous Air Pollutants (NESHAP), it was estimated that of the 1,024 bulk terminals, approximately 70 percent were controlling VOC emissions from the loading racks. Additionally, it was est
38、imated that 63,520 megagrams (Mg) of VOC and 3,460 Mg of HAP are released from loading racks at bulk terminals on an annual basis .2 To estimate the HAP emissions from bulk terminals, it was previously assumed that the relative HAP and VOC compositions of the vapor stream after control are equal to
39、the relative compositions prior to control. This study was launched to measure HAP emissions and test the validity of this assumption. The objective of this study is to measure emissions from the loading of gasoline cargo tanks at loading facilities (i.e., bulk terminals) and present a method for de
40、termining emission factors for these sources. The emission factors apply to loading facilities which utilize carbon adsorption units or thermal oxidizers to reduce gasoline emissions. Section 2 presents the test methods used for the study. Section 3 evaluates the quality of each of the 33 tests incl
41、uded in the study. Section 4 presents the results of the emission tests and summarizes the calculated control efficiencies for HAPs. Section 5 presents example calculations illustrating the development of emission factors using the test results and currently available bulk terminal emission informat
42、ion. A discussion of sensitive parameters that may impact these results is also presented in 1-1 STD-APIIPETRO PUBL 347-ENGL L99B 0732290 OblL87b 3T7 Section 5. Section 6 lists the references used or referred to in this report. Appendix A contains the sampling and analytical protocols used in this s
43、tudy. Appendix B presents detailed information on the 20 data sets used to calculate the emission factors. Appendix C presents detailed information on the 13 data sets excluded from the emission factor calculations. 1-2 SECTION 2 TEST METHODS For this study, API sponsored HAP emissions testing at 33
44、 bulk gasoline terminals around the United States. Each test measured emissions from facilities with a vapor control system. Emission tests from 23 carbon adsorption, eight thermal oxidizers, and two refrigeration units were included. This section describes the sampling and analytical procedures use

SAMPLING TECHNIQUES Simultaneous with the VOC emissions testing, testing was performed for selected HAPS using a test protocol developed by API for this study.3 Six gas samples were extracted (three inlet samples simultaneous with three outlet samples) at set two hour intervals during the first s
46、ix hours of the VOC emissions test. EPA Method 18, Section 7.1 sampling procedures were followed. To prevent contamination, new Teflon“ tubing and new Tedlar bags were used for each test. After the initial sampling, all Tedlar“ bag gas samples were sub-sampled into SUMMA“ polished canisters followin
