prEN 1918-1 Viešoji apklausa

Komentavimo iki data 2025-08-05

Dujų infrastruktūra. Požeminė dujų saugykla. 1 dalis. Funkcinės rekomendacijos dėl saugyklų vandeninguose sluoksniuose

This document covers the functional recommendations for design, construction, testing, commissioning, operation, maintenance and abandonment of underground gas storage (UGS) facilities in aquifers up to and including the wellhead. It specifies practices, which are safe and environmentally acceptable. For necessary surface facilities for underground gas storage, EN 1918 5 applies. In this context “gas” refers to flammable gas: — which is in a gaseous state at a temperature of 15 °C and under a pressure of 0,1 MPa (the stored product is also named fluid); — which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements. This comprises: — gas not in liquid phase under subsurface conditions; — methane-rich gases; — natural gas; — biomethane; — synthetic methane; — hydrogen of various purities; — any mixtures of the gases above; — hydrocarbon gas in liquid phase under subsurface conditions such as; — ethylene; — liquified petroleum gas (LPG). NOTE 1 Correspondingly the EN 1918 series can be considered where applicable for underground storage of any other fluid e.g. helium, carbon dioxide, compressed air, rDME (renewable dimethyl ether) and hydrogen transport fluids (such as ammonia and LOHC). This document is not intended to be applied retrospectively to existing facilities. NOTE 2 Correspondingly this document can be considered for major conversions in case of significant change of gas composition.

Gamtinės dujos. Aiškinamasis žodynas (ISO/DIS 14532:2025)

ISO 14532:2014 establishes the terms, definitions, symbols, and abbreviations used in the field of natural gas. The terms and definitions have been reviewed and studied in order to cover all aspects of any particular term with input from other sources such as European Standards from CEN (The European Committee for Standardization), national standards, and existing definitions in the IGU Dictionary of the Gas Industry. The definitive intention of ISO 14532:2014 is to incorporate the reviewed definitions into the ISO/TC 193 source standards.
