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 von flüchtigen organischen Verbindungen in die Atmosphäre

Dieses Dokument legt einen Rahmen zur Bestimmung von Emissionen flüchtiger organischer Verbindungen (VOC) in die Atmosphäre fest. Es definiert ein System von Verfahren zur Erkennung und/oder Identifizierung und/oder Quantifizierung von VOC Emissionen aus industriellen Quellen. 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 an die petrochemische, ölverarbeitende und chemische Industrie, die VOC 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.
Dieses Dokument gilt für diffuse VOC Emissionen in die Atmosphäre, schließt jedoch VOC Emissionen in Wasser und feste Materialien wie Böden aus. Es ergänzt EN 15446 [9], das die Erkennung, Lokalisierung von Quellen (einzelne Leckagen aus Anlagen und Rohrleitungen) und die Quantifizierung fugitiver VOC Emissionen innerhalb des Anwendungsbereichs des Programms für Leckerkennung und  reparatur (en: leak detection and repair, LDAR) abdeckt.
Dieses Dokument wurde für Nichtmethan VOC 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 définit 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 précise les méthodologies permettant de mettre en oeuvre tous les éléments ci-dessus, et définit également les exigences de performance 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.
Le présent document traite des émissions diffuses de COV dans l'atmosphère, mais exclut les émissions de COV dans l'eau et dans les matériaux solides tels que les sols. Il complète l'EN 15446 [9], qui couvre 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 les méthodologies sont en principe applicables au méthane et à d'autres gaz.
Le présent document définit 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.
