原标题：NextDecade优化Rio Grande LNG项目
中国石化新闻网讯 据全球能源新闻网7月15日报道，液化天然气开发公司NextDecade公司正在优化其Rio Grande LNG项目(RGLNG)。在对该项目做最终投资决定之前开发活动的整个过程中，NextDecade一直在努力减少RGLNG对环境的影响。
RGLNG最初的前端工程和设计基于6条液化天然气生产线，每条LNG生产线每年可生产450万吨液化天然气供出口。在2015年和2016年被联邦能源管理委员会(FERC)选中并提交申请的技术，在五年的许可期内得到了发展;如今，液化天然气生产线的效率更高，生产更多液化天然气的同时，二氧化碳当量(CO2e)的总排放量也更低。多个优化方案已经被确定，这将导致一个世界级的液化天然气项目的交付，只需5条而不是6条每年能够生产2700万吨的液化天然气生产线。
与NextDecade最初的六条生产线项目相比，这些优化措施的实施将为环境和社区带来诸多好处，其中包括：（i）减少约21％的CO2e排放；（ii）缩短整个27 mtpa项目的建设时间，（iii）减少设施占用空间；以及（iv）预计道路交通量的减少。
NextDecade董事长兼首席执行官马特·沙茨曼(Matt Schatzman)表示，“对我们所有的利益相关者来说，这是一个极其积极的发展，因为这些优化带来的环境效益是显著的。除了实现减排目标之外，这些优化措施还将减少项目的占地面积，交通量和施工进度，并显示我们对里奥格兰德河谷社区的持续承诺。
由于进行了这些优化，NextDecade将在适当时候退出第6条生产线，因为RGLNG现在仅用5条生产线就能生产出相同的计划LNG量。第6条生产线的未来发展将要求NextDecade获得FERC，美国能源部以及对出口项目具有管辖权的任何其他相关联邦或州机构的授权。

NEXTDECADE TO OPTIMIZE RIO GRANDE LNG PROJECT
NextDecade Corporation is optimizing its Rio Grande LNG project (RGLNG). Throughout the course of its pre-FID development activities, NextDecade has worked diligently to reduce the environmental impacts of RGLNG.
The original front-end engineering and design for RGLNG was based on six LNG trains each capable of producing 4.5 million metric tonnes per annum (mtpa) of LNG for export. The technologies that were selected and filed with the Federal Energy Regulatory Commission (FERC) in 2015 and 2016 have evolved over the five-year permitting period; the LNG trains are now more efficient and will produce more LNG with lower total carbon dioxide equivalent (CO2e) emissions. Multiple optimizations have been identified that will lead to the delivery of a world-class LNG project capable of producing 27 mtpa with just five LNG trains instead of six.
Implementation of these optimizations will result in several environmental and community benefits when compared with NextDecade’s original six-train project including (i) approximately 21 percent lower CO2e emissions, (ii) shortened construction timeline for the full 27 mtpa project, (iii) reduced facility footprint, and (iv) an expected reduction in traffic on roadways.
“This is an extremely positive development for all of our stakeholders, as the environmental benefits from these optimizations are significant,” said Matt Schatzman, NextDecade’s Chairman and Chief Executive Officer. “In addition to the emissions reductions we will achieve, these optimizations will reduce the project’s footprint, traffic, and construction schedule, and demonstrate our ongoing commitments to the community in the Rio Grande Valley.”、
On account of these optimizations, NextDecade will, in due course, vacate Train 6 as RGLNG is now capable of producing the same planned total LNG volumes with just five trains. Future development of Train 6 will require NextDecade to secure authorization from FERC, the U.S. Department of Energy, and any other relevant federal or state agency with jurisdiction over the export project
