DIN EN 17928-1
Gas infrastructure - Injection stations - Part 1: General requirements
Gasinfrastruktur - Einspeiseanlagen - Teil 1: Allgemeine Anforderungen
Brief description
This document describes functional requirements of stations for the injection of biomethane, substitute natural gas (SNG) and hydrogen fuel gas into gas transmission and distribution systems operated with fuel gases (natural gas, biomethane, SNG, hydrogen fuel gas, fuel gas mixtures, etc.) in accordance with European technical rules that ensure the interoperability of systems. Figure 1 describes the general approach including all the relevant functions that can be installed in different configurations. [Figure 1 - Example of an injection station with gas purification] This document also applies to refeeding stations that feed such gases back into upstream gas supply networks, [Figure 2 - Refeeding station] This document represents the state of the art at the time of its preparation. This document does not apply to injection stations operating prior to the publication of this document. This document specifies common basic principles for gas infrastructure. Users of this document are expected to be aware of more detailed national standards and/or codes of practice in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) gives: - clarification of all legislations/regulations applicable in a member state; - if appropriate, more restrictive national requirements; - a national contact point for the latest information.
