石油圈中国石化新闻网讯 据OGJ网12月5日消息 美国能源部向国会提交的一份报告中建议，阿巴拉契亚甲烷储存和分配中心的开发将为附近马塞勒斯和尤蒂卡页岩中的低成本天然气提供重要市场，同时将石油化工项目吸引到墨西哥湾以外地区，那里95%现有的美国产能都集中在那里。 美国证券交易委员会里克佩里在12月4日的国家石油委员会说：“我们的报告显示，美国在抢占全球石化市场很大份额方面有着巨大的潜力，我们也有潜力使石化产品多样化，在阿巴拉契亚建设产能是一个千载难逢的机会。” 报告指出，美国现在是世界上最大的天然气生产国，而且还有天然气凝析液乙烷的优势，乙烷在石油化工生产中尤其有用。报告称，阿巴拉契亚盆地的乙烷生产预计到2025年持续快速增长至640000桶/日，是5年前的20多倍。 报告称，美国能源信息局的数据显示，俄亥俄州、宾夕法尼亚州和西弗吉尼亚州的天然气产量增长如此迅速，以至于它们在美国天然气总产量的合计份额从2008年的2%跃升到2017年的27%。 该报告称，阿巴拉契亚气液化石油气的加工和分馏能力已迅速提升，以适应天然气产量的增加，但阿巴拉契亚地区目前缺乏用于连接供应和需求来源（包括天然气凝析液NGL的储存）枢纽的实体系统。 能源部表示，它通过与目前已经应用于墨西哥湾沿岸和二叠纪盆地的现有枢纽进行比较，检验了该地建立枢纽的潜力，这些枢纽占了美国在阿巴拉契亚以外地区NGLs增长的大部分。此外，该报告的市场分析强调说，阿巴拉契亚枢纽的发展可以为美国提供竞争优势，以增加其在全球石化市场的份额，同时不与墨西哥湾沿岸的扩张冲突。 王磊 摘译自 OGJ 原文如下： Development of an Appalachian methane storage and distribution hub would provide an important market for low-cost natural gas from the nearby Marcellus and Utica shales while attracting petrochemical projects to an area outside the Gulf Coast, where 95% of existing US capacity now is concentrated, a US Department of Energy report to Congress suggested. “Our report shows there’s significant potential for the US to grab a large share of the global petrochemical market,” US Sec. of Energy Rick Perry told the National Petroleum Council on Dec. 4. “We have the potential to diversify our petrochemical footprint. Building capacity in Appalachia is a once-in-a-lifetime opportunity.” The report pointed out that the US now is the world’s largest gas producer, with an additional benefit of more natural gas liquids including ethane—particularly useful in petrochemical manufacturing. Appalachian basin ethane production is projected to continue rapid growth through 2025 to 640,000 b/d, more than 20 times greater than just 5 years ago, the report said. It said that figures from the US Energy Information Administration show production in Ohio, Pennsylvania, and West Virginia have increased so rapidly that their combined share of total US gas production has jumped to 27% in 2017 from just 2% in 2008. Gas liquids processing and fractionating capacity in Appalachia has increased rapidly to match this gas production increase, but the Appalachian region currently lacks other physical systems for a hub that would connect supply and demand sources, including NGL storage, the report said. It examined the potential for a hub there by comparing it to existing hubs that already serve the Gulf Coast and Permian basin, which account for most of the US growth in NGLs outside of Appalachia. In addition, market analysis from the report emphasizes that the development of an Appalachian hub may offer a competitive advantage for the US to increase its global petrochemical market share while not conflicting with Gulf Coast expansion, DOE said.
