DANSK DSF/ISO/FDIS 20675 PDF

This International Standard defines terms and describes classifications related to biogas production by anaerobic digestion, gasification from biomass and power to gas from biomass sources, biogas conditioning, biogas upgrading and biogas utilization from a safety, environmental, performance and functionality perspective, during the design, manufacturing, installation, construction, testing, commissioning, acceptance, operation, regular inspection and maintenance phases. Biogas installations are amongst others applied at industrial plants like food and beverage industries, waste water treatment plants, waste plants, landfill sites, small scale plants next to agricultural companies and small scale household installations. 1.2 Explanation of the scope Biogas is produced by making use of one or more of the following types of installations: – Biomass storage and preparation (see Table 1 for more detail). – Biomass to biogas processes (see Table 1 for more detail): – Anaerobic digestion – Gasification from biomass – Power to Gas from biomass sources – Biogas, biomethane and syngas storage and management (including flares). – Biogas treatment: – Biogas de-watering and cleaning (e.g. hydrogen sulphide and siloxanes) – Biogas to biomethane process: – Upgrading – Combined upgrading and liquefaction – Biogas and biomethane applications: – Raw material for chemical processes – Transportation fuel (liquefied or compressed) – Biogas combustion processes, as far as it concerns applications which are directly and specifically used for biogas: – Boilers used for locally produced biogas. – Burners used for locally produced biogas. – Furnaces used for locally produced biogas. – Lightening by locally produced biogas. – Flares. – Combined Heat and Power (CHP) installations, such as: – Micro gasturbines. – Fuel cells. – Gas engines. – Biogas and biomethane distribution: – Compression and pressure regulation installations. – Injection into the pipeline: – Public grid. – Private grid (e.g. raw biogas and treated biogas). – Liquefaction. – Re-fuelling stations. – Process and safety control. – Digestate storage and digestate conversion (separation of minerals) including manure conversion and conversion of sludge. The following topics are excluded from this International Standard: – Boilers, burners, furnaces and lightening in case these are not specifically applied for locally produced biogas. – Gas fuelled engines for vehicles and ships. – The public gas grid. – Specifications to determine biomethane quality. – Transportation of compressed or liquefied biogas. – Transportation of biomass or digestate. – Assessment and determination whether biomass is sourced sustainably or not.
