Fugitive and diffuse emissions of common concern to industry sectors - Standard method to determine diffuse emissions of volatile organic compounds into the atmosphere

This document specifies the framework for determining emissions to the atmosphere of Volatile Organic Compounds (VOCs). It defines a system of methods to detect and/or identify and/or quantify VOC emissions from industrial sources. These methods include Optical Gas Imaging (OGI), Differential Absorption Lidar (DIAL), Solar Occultation Flux (SOF), Tracer Correlation (TC), and Reverse Dispersion Modelling (RDM). It specifies the methodologies for carrying out all the above, and also defines the performance requirements and capabilities of the direct monitoring methods, the requirements for the results and their measurement uncertainties.
This document specifically addresses, but is not restricted to, the petrochemicals, oil refining, and chemical industries receiving, processing, storing, and/or exporting of VOCs, and includes the emissions of VOCs from the natural gas processing/conditioning industry and the storage of natural gas and similar fuels.
This document addresses diffuse VOC emissions to atmosphere but excludes the emissions of VOCs into water and into solid materials such as soils. It is complementary to EN 15446 [9], which covers detection, localization of sources (individual leaks from equipment and piping), and quantification of fugitive VOC emissions within the scope of a Leak Detection and Repair Programme (LDAR).
This document has been validated for non-methane VOCs, but the methodologies are in principle applicable to methane and other gases.
This document defines methods to determine (detect, identify and/or quantify) VOC emissions during the periods of monitoring. It does not address the extrapolation of emissions to time periods beyond the monitoring period.

Fugitive und diffuse Emissionen von allgemeinem Interesse für Industriebereiche - Verfahren zur Bestimmung diffuser Emissionen flüchtiger organischer Verbindungen in die Atmosphäre

Dieses Dokument legt einen Rahmen zur Bestimmung von Emissionen flüchtiger organischer Verbindungen (VOCs) in die Atmosphäre fest. Es legt ein System von Verfahren zur Erkennung und/oder Identifizierung und/oder Quantifizierung von VOC Emissionen aus industriellen Quellen fest. Diese Verfahren umfassen die optische Gasdetektion (en: Optical Gas Imaging (OGI)), Differential Absorption Lidar (DIAL), Solar Occultation Flux (SOF), Tracer Korrelation (en: Tracer Correlation (TC)) und inverse Ausbreitungs¬rechnung (en: Reverse Dispersion Modelling (RDM)). Das Dokument legt die Methodik für die Ausführung der genannten Verfahren fest und definiert darüber hinaus die Leistungsanforderungen und Möglichkeiten dieser direkten Messverfahren sowie die Anforderungen an die Ergebnisse und ihre Messunsicherheiten.
Dieses Dokument richtet sich vor allem, aber nicht ausschließlich, an die petrochemische, ölverarbeitende und chemische Industrie, die VOCs transportieren, verarbeiten, lagern und/oder exportieren und zielt auch auf VOC Emissionen aus der Erdgas verarbeitenden/aufbereitenden Industrie und die Lagerung von Erdgas und ähnlichen Brennstoffen. Die in diesem Dokument festgelegten Verfahren wurden an Anlagen auf dem Festland validiert.
Dieses Dokument ist anzuwenden für diffuse VOC Emissionen in die Atmosphäre, nicht jedoch für VOC Emissionen in Wasser und feste Materialien wie Böden. Es ergänzt EN 15446 [9], das normierte Verfahren zur Erkennung, Lokalisierung von Quellen (einzelne Leckagen aus Anlagen und Rohrleitungen) und Quantifizierung fugitiver VOC Emissionen innerhalb des Anwendungsbereichs des Programms für Leckerkennung und -reparatur (en: leak detection and repair, LDAR).
Dieses Dokument wurde für Nichtmethan VOCs validiert, die Methodik ist jedoch grundsätzlich auf Methan und andere Gase anwendbar.
Dieses Dokument legt Verfahren zur Bestimmung (Erkennung, Identifizierung und/oder Quantifizierung) von VOC Emissionen während der Überwachungszeiträume fest. Es behandelt nicht die Extrapolation von Emissionen auf Zeiträume über die Überwachungszeiträume hinaus.

Émissions fugitives et diffuses concernant les secteurs industriels - Méthode normalisée pour la détermination des émissions diffuses de composés organiques volatils dans l'atmosphère

Le présent document spécifie le cadre pour la détermination des émissions dans l'atmosphère de composés organiques volatils (COV). Il spécifie un système de méthodes pour détecter et/ou identifier et/ou quantifier les émissions de COV provenant de sources industrielles. Ces méthodes comprennent l'imagerie optique de gaz (OGI), le lidar à absorption différentielle (DIAL), l'occultation solaire par le flux (SOF), le traçage gazeux (TC) et la modélisation inverse de la dispersion (RDM). Il spécifie les méthodologies permettant de mettre en œuvre tous les éléments ci-dessus, ainsi que les exigences de performances et les capacités des méthodes de surveillance directe, les exigences relatives aux résultats et leurs incertitudes de mesure.
Le présent document traite plus particulièrement, mais sans s'y limiter, de la pétrochimie, du raffinage du pétrole et des industries chimiques qui reçoivent, traitent, stockent et/ou exportent des COV, et inclut les émissions de COV provenant de l'industrie de traitement et de conditionnement du gaz naturel et du stockage du gaz naturel et de combustibles similaires. Les méthodes spécifiées dans le présent document ont été validées sur des installations terrestres.
Le présent document est applicable aux émissions diffuses de COV dans l'atmosphère, mais il ne s'applique pas aux émissions de COV dans l'eau et dans les matériaux solides tels que les sols. Il complète l'EN 15446 [9], méthode normalisée pour la détection, la localisation des sources (fuites individuelles d'équipements et de tuyauteries) et la quantification des émissions fugitives de COV dans le cadre d'un programme de détection et de réparation des fuites (LDAR).
Le présent document a été validé pour les COV non méthaniques, mais la méthodologie est en principe applicable au méthane et à d'autres gaz.
Le présent document spécifie les méthodes permettant de déterminer (détecter, identifier et/ou quantifier) les émissions de COV pendant les périodes de surveillance. Il ne traite pas de l'extrapolation des émissions sur des périodes postérieures à la période de surveillance.

Ubežne in razpršene emisije skupnega pomena za industrijske sektorje - Standardna metoda za določevanje razpršenih emisij hlapnih organskih spojin v ozračje

Ta dokument določa okvir za določanje emisij hlapnih organskih spojin (VOC) v ozračje. V njem je opredeljen sistem metod za zaznavanje in/ali identifikacijo in/ali količinsko opredelitev emisij hlapnih organskih spojin iz industrijskih virov. Te metode vključujejo optično odkrivanje plina (OGI), diferencialni absorpcijski LIDAR (DIAL), zasenčenje sončnega toka (SOF), korelacijsko metodo s slednim plinom (TC) in obratno disperzno modeliranje (RDM). Dokument določa metodologije za izvedbo vsega zgoraj navedenega, v njem pa so opredeljene tudi zahteve glede zmogljivosti in zmožnosti neposrednih metod spremljanja, zahteve za rezultate in njihove merilne negotovosti.
Ta dokument med drugim posebej obravnava petrokemično industrijo, industrijo rafiniranja nafte in kemično industrijo, ki sprejemajo, predelujejo, shranjujejo in/ali izvažajo hlapne organske spojine, in vključuje emisije hlapnih organskih spojin iz industrije predelave/kondicioniranja zemeljskega plina ter skladiščenja zemeljskega plina in podobnih goriv.
Ta dokument obravnava razpršene emisije hlapnih organskih spojin v ozračje, vendar izključuje emisije hlapnih organskih spojin v vodo in trdne materiale, kot so tla. Dopolnjuje standard EN 15446 [9], ki zajema odkrivanje, lokalizacijo virov (posamezne točke puščanja iz opreme in cevi) ter količinsko opredelitev nezajetih emisij hlapnih organskih spojin v okviru programa za odkrivanje in odpravo puščanja (LDAR).
Ta dokument je bil odobren za nemetanske hlapne organske spojine, vendar se lahko metodologije načeloma uporabljajo za metan in druge pline.
V tem dokumentu so opredeljene metode za določanje (zaznavanje, identifikacijo in/ali količinsko opredelitev) emisij hlapnih organskih spojin v obdobjih spremljanja. V njem niso obravnavane ekstrapolacije emisij na časovna obdobja zunaj obdobij spremljanja.
