摘要
考虑深圳市目前及潜在天然气气源的多样性、燃气互换性、天然气类别及燃具适应性,对深圳市天然气基准气的选择进行了探讨。深圳市使用的天然气应符合GB 17820—1999《天然气》中一、二类天然气的技术指标,以及GB/T 19207—2003《液化天然气的一般特性》中甲烷体积分数的要求,对照GB/T 13611—2006《城市燃气分类和基本特性》确定基准气类别。深圳市目前使用的天然气(澳洲LNG、新疆LNG)符合12T范围,考虑潜在天然气气源,深圳市天然气的基准气类别宜选择12T。
Considering the multiplicity of existing and potential natural gas source in Shenzhen City, gas exchangeability, natural gas category and gas appliance adaptability, the selection of reference natural gas in Shenzhen City is discussed. The natural gas utilized in Shenzhen City should accord with the technical indexes of category 1 and 2 natural gas in Natural Gas （ GB 17820 - 1999 ） and the requirement for methane volume fraction in General Characteristics of Liquefied Natural Gas （ GB/T 19207 - 2003 ）. The reference gas category is determined against Classification and General Characteristics of City Gas （GB/T 13611 -2006）. The existing Australian LNG and Xinjiang LNG utilized in Shenzhen City accord with 12 T. In consideration of potential natural gas source, 12 T should be selected as the reference natural gas in Shenzhen City.
