中国石化新闻网讯 据碳氢加工网8月15日消息，根据钱尼尔项目工程总监Judy Clark透露，到2020年，按产能计算，这家液化天然气运营商将成为全球第二大液化天然气运营商。目前，钱尼尔约占美国运营或在建LNG出口能力的一半。 Clark女士的发言集中在钱尼尔开发两个液化天然气站点（萨宾帕斯和科珀斯克里斯蒂）时所面临的几个挑战，并提及了对科珀斯克里斯蒂LNG终端的扩建。到2020年，钱尼尔的液化天然气产能预计将超过3100万吨/年。这包括萨宾帕斯的五条液化生产线和科珀斯克里斯蒂的两条液化生产线。该公司还在萨宾帕斯开发第六条生产线——通过最终投资决策并完全获得批准，总产能450万吨/年，并在科珀斯克里斯蒂开发第三条生产线(2022年完工)，以及一个产能950万吨/年的中型液化天然气项目。在萨宾帕斯和科珀斯克里斯蒂站点的建设过程中，钱尼尔面临着几项工程和无法控制的挑战。主要挑战之一是无法控制的市场变化。克拉克表示：“当萨宾帕斯站点建成时，它最初是作为一个进口终端，美国页岩气生产的开始彻底改变了美国液化天然气行业的市场动态。这一转变导致了在现有设施上增加新的液化生产线的额外投资。” 钱尼尔在萨宾帕斯和科珀斯克里斯蒂必须克服的其他挑战包括： •地质/土壤条件差 •必须合并多个废物管理单元(如铝土矿处置区、污泥放置区、危险废物处置区) •必须清除地下管线和其他障碍 •排水系统需要改善 •必须穿过现有管道 •需要保护海洋海草 另一个主要因素是自然力量。这两个地点都处在三场飓风的路径上：丽塔、艾克和哈维。然而，这两个地点都没有遭受任何重大破坏。在飓风哈维袭击期间，科珀斯克里斯蒂站点仅损失了大约一周的施工时间。 科珀斯克里斯蒂站点还将在三条生产线之外进行扩展。钱尼尔计划开始第三阶段的工作(例如，CCL第三阶段)，包括建造7条中型LNG生产线。该项目的最终投资决策计划于2020年开始，并将于2025年开始运营。一旦完成，第1-7号生产线的总产能将达到9500吨/年。 裘寅 编译自 碳氢加工网 原文如下： Cheniere to become the second-largest LNG operator by 2020 According to Judy Clark, Director, Project Engineering, Cheniere, the LNG operator will become the second-largest LNG operator by capacity by 2020. At present, Cheniere accounts for approximately half of US LNG export capacity in operation or under construction. These facts were discussed during the Rice Global Engineering and Construction Forum (RGF) roundtable. Held monthly on the Rice University campus in Houston, Texas, the RGF roundtable discusses the latest challenges and opportunities facing the contracting side of the global engineering and construction industry. Ms. Clark’s discussion focused on several challenges that Cheniere faced in developing two LNG sites—Sabine Pass and Corpus Christi—and a sneak peek at the expansion of the Corpus Christi LNG terminal. By 2020, Cheniere expects to have more than 31 MMtpy of LNG capacity operational. This includes five liquefaction trains at Sabine Pass and two liquefaction trains at Corpus Christi. The company is also developing a sixth train at Sabine Pass—FID greenlighted and fully permitted, with a total capacity of 4.5 MMtpy—and a third train at Corpus Christi (completion by 2022), along with an 9.5-MMtpy mid-scale LNG project. During the construction of Sabine Pass and Corpus Christi, Cheniere faced several engineering and uncontrollable challenges. One of the major challenges was uncontrollable market changes. “When Sabine Pass was built, it was originally set up as an import terminal,” said Mr. Clark, “the onset of US shale gas production completely changed market dynamics for the US LNG industry. This shift led to additional investments in adding new liquefaction trains to the existing facility.” Additional challenges Cheniere had to overcome at Sabine Pass and Corpus Christi included: •Geology/poor soil conditions •Multiple waste management units had to be incorporated (e.g., bauxite disposal area, sludge placement area, hazardous waste disposal) •Underground distribution piping and other obstacles had to be cleared •Drainage improvements were needed •Existing pipelines had to be traversed •Needed to preserve marine seagrass. Another major factor was Mother Nature. Both sites were in the path of three hurricanes: Rita, Ike and Harvey. However, neither site succumbed to any major damage. The Corpus Christi site only lost approximately one week of construction time during Hurricane Harvey. The Corpus Christi site is also being expanded beyond three liquefaction trains. Cheniere plans to begin Phase 3 work (e.g., CCL Stage 3), which includes the construction of seven midscale LNG trains. FID on the project is scheduled for 2020, with operations to begin in 2025. Once completed, Trains 1–7 will have a total capacity of 9.5 MMtpy.
