23、 11771:2011-04 3Introduction This Intenational Standard describes the measurement procedures necessary to determine the mass emission of substances from stationary sources. Empirically generated data are necessary to determine the uncertainty that can be associated with a stated result and to enable
24、 the verification of emission measurement reports. This Intenational Standard also describes the measurement procedures necessary to determine emission factors. An emission factor is a value that relates the quantity of a pollutant released with an activity associated with the release of that pollut
25、ant. Emission factors are useful when the operational conditions and time period for which they are representative is known. Emission factors are used to calculate and report mass emissions for both emission inventory and non-inventory uses. Inventory uses can include: emission trading; compiling po
26、lluting release and transfer registers; air quality modelling; air quality management; compliance with national emission limits. Non-inventory uses can include: developing site-specific emission estimates; developing control strategies; risk assessments; deciding appropriate permit limits. The most
27、commonly used methodology for compiling an emission inventory is to combine information on the extent to which an activity takes place (quantified by activity data a) with representative values of the emissions or removals per unit activity, called emission factor F. The basic equation providing the
28、 emission as a mass emission rate m is given by based on a limited number of emission measurements; representative of a restricted pe riod of process operating time; representative of a limited range of process operating conditions; representative of a limited sample of process units commonly used.
29、Emission factors are numerical estimates with uncertainties that can include systematic and random components, e.g. measurement uncertainty, fluctuations in pollutant emission control efficiency, and variability in process operation. The numerical uncertainty associated with a particular emission fa
30、ctor, for a single source, can be estimated provided that there is sufficient, high quality, source test data to estimate statistically the underlying variability of the more important influencing factors. Uncertainty also arises from the use of an emission factor applicable to one activity, process
31、, technology or installation being used to represent a situation for which it is unsuitable. In many cases, it is not possible to quantify the uncertainty introduced through inappropriate use of emission factors, and this situation is discouraged. Emission factors should be used with caution. Altern
32、ative means exist for estimating emissions that can be more appropriate under some circumstances. A material balance can provide an adequate quantification of emissions in situations where a high percentage of material is lost to the atmosphere (e.g. carbon and sulfur in fuel, solvent loss in an unc
33、ontrolled coating process). Material or mass balance determinations can also account for fugitive emissions not easily measured otherwise. In contrast, material balances may be inappropriate where material is consumed or chemically combined in the process, or where losses to the atmosphere are a sma
34、ll portion of the total process throughput. Data from frequent and representative source-specific emissions measurements or continuous emission monitoring systems can provide measures of actual pollutant emissions from a source. Site-specific measurement data from a limited number of emissions measu
35、rements, while improving the certainty of the emission data, represent only the conditions existing at the time of the testing or monitoring. To improve the estimate of longer-term (e.g. daily, monthly, yearly) emissions, conditions under which tests occur should be representative of the sources exp
36、ected range of operations. NOTE 2 Even in the absence of representative source-specific data, emission information from process control technique and abatement system vendors, particularly emission performance guarantees or emission measurement data from similar equipment can still be a better sourc
37、e of information than source-category emission factors. This International Standard requires the use of supporting standards not all of which are yet available. EN ISO 11771:2010 (E) DIN EN ISO 11771:2011-04 51 Scope This International Standard specifies a generic method for the determination and th
38、e reporting of time-averaged mass emissions from a specific installation or of a family of installations (or common source type), using data collected by measurements, and by establishing: mass emission rates by the simultaneous meas urement of concentration and gas flow, using standardized manual o
39、r automatic methods, and also the estimation of the uncertainty of the measurements; time-averaged mass emission rates using time series of mass emission rate values, their uncertainty characteristics, and also the determination of the expanded uncertainty of the average; time-averaged emission fact
40、ors for a specific installation or of a family of installations and their associated uncertainty characteristics; a quality management system to assist the process of inventory qu ality assurance and verification. This International Standard is applicable to the determination of emission factors for
41、 stationary sources including emissions from industrial processes where calculation from fuel and raw material is not practical, for greenhouse gases, and air pollutants including fine particulate material. This International Standard does not address compliance monitoring in the context of emission
42、 control regulations. This International Standard requires the use of measurement-based methods and calculation-based methods that use measurement data. It covers the planning and execution of the measurement programme to collect data, selection of sampling methods, calculation of results, estimatio
43、n of uncertainty, determination of emission factors, and the reporting of information in a form that enables users to apply them. This International Standard specifies how to: generate time-averaged mass emission rate data of a known quality, for a defined period of time, and a documented set of ope
44、rational conditions; generate complete data sets representative of a known time period (i.e. a calendar year) by filling gaps in mass emission rate data series and combining data sets numerically; NOTE 1 Time series data can be available for only a limited elapsed period (i.e. weeks, months, or year
45、s) and can be available only for a discrete process whereas inventories can be necessary which average over a different period (i.e. for a calendar year). calculate emission factors for a known time period; calculate time-averaged emission factors of a known quality for a known source type. The meas
46、urement of emissions from vehicular, area or fugitive sources is not specifically covered. However, this International Standard can be used for quantification of emission factors for those sources provided that measurements of emissions are available. NOTE 2 Emission fluxes from fugitive and area so
47、urces can be directly measured using optical open-path techniques. The results from these measurements can be treated in an analogous way to the measurements described in this International Standard to determine time-averaged emissions and emission factors.
