沼气 - 沼气生产 调节 升级和利用 - 术语 定义和分类方案

[中文适用范围]： 本文件从安全、环境、性能和功能的角度定义了与厌氧消化沼气生产、生物质气化和生物质来源发电、沼气调节、沼气升级和沼气利用相关的术语和分类。 、安装、施工、试验、调试、验收、运行、定期检查和维护等阶段。 沼气装置主要应用于食品和饮料行业等工业工厂、废水处理厂、废物处理厂、垃圾填埋场、农业公司旁边的小型工厂以及小型家庭装置。 本文件不包括以下主题： ——锅炉、燃烧器、熔炉和照明设备，如果它们不是专门用于本地生产的沼气； ——车辆和船舶用燃气发动机； ——公共燃气网； ——确定生物甲烷质量的规范； ——压缩或液化沼气的运输； ——生物质或沼渣的运输； ——评估和确定生物质的来源是否可持续。 本文件还描述了以下内容以供参考： ——确定尺寸的参数（例如小型、中型或大型）； ——确定安装类型的参数（例如家用、工业）； ——描述技术类型的参数； ——制定沼气装置健康、安全和环境保护指南的术语和流程。 注：有关范围的说明，请参阅附录 A。 [外文原描述]： ISO 20675:2018 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, among 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. The following topics are excluded from this document: - 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. ISO 20675:2018 describes the following for information purposes as well: - the parameters to determine the size (e.g. small, medium-sized, or large scale); - the parameters to determine the type of installation (e.g. domestic, industrial); - the parameters to describe the type of technique; - terms and processes in order to develop health, safety and environmental protection guidelines for biogas installations.
