记者从中国海油获悉,由中国自主设计建造的全球单罐容量最大的液化天然气储罐群——中国海油盐城“绿能港”项目6座27万立方米液化天然气储罐近日在江苏盐城全部建设完工,标志着中国规模最大的液化天然气储备基地全面建成。
中国海油盐城“绿能港”项目位于江苏省盐城市滨海港工业园区,项目包含4座22万立方米液化天然气储罐和此次建设完成的6座27万立方米液化天然气储罐,总罐容达250万立方米,可满足千万户家庭8个月的生活用气,是国家天然气产供储销体系建设及互联互通重点规划项目。
储罐是液化天然气接收站的关键装备,不仅存储的介质为-162℃的液化天然气,还需经受火灾、爆炸、地震等极端工况考验,设计建造工艺十分复杂。中国海油气电集团副总经理李峰介绍:“盐城‘绿能港’的10座液化天然气储罐全部采用中国海油自主技术设计建造,项目国产化率达98.3%,其中12项技术成果填补了国内空白,达到世界领先水平,6座27万立方米储罐为全球首次建设,储罐高约65米,直径100.6米,可同时叠放3架C919客机,罐容相当于614个标准游泳池大小,可存储1.69亿立方米天然气。”
The reporter learned from China National Offshore Oil (CNOOC) that the world's largest single tank capacity of liquefied natural gas storage tank group, designed and built by China's own CNOOC Yancheng "Green Energy Port" project six 270,000 cubic meters of liquefied natural gas storage tanks have recently been completed in Yancheng, Jiangsu Province, marking the completion of China's largest liquefied natural gas reserve base.
Cnooc Yancheng "Green Energy Port" project is located in Binhai Port Industrial Park, Yancheng City, Jiangsu Province. The project includes four 220,000 cubic meters of LNG storage tanks and six 270,000 cubic meters of LNG storage tanks completed this time, with a total tank capacity of 2.5 million cubic meters, which can meet the domestic gas consumption of tens of millions of households for 8 months. It is a key planning project for the construction and interconnection of the national natural gas production, supply, storage and marketing system.
Storage tank is the key equipment of LNG receiving station, not only the storage medium of -162℃ LNG, but also the test of extreme conditions such as fire, explosion, earthquake, etc., the design and construction process is very complicated. Li Feng, deputy general manager of China Sea Oil & Gas Power Group, introduced: "Yancheng 'Green Energy Port' 10 liquefied natural gas storage tanks are all designed and built by CNOOC's independent technology, the project localization rate of 98.3%, of which 12 technical achievements fill the domestic gap, reaching the world's leading level, six 270,000 cubic meters of storage tanks for the world's first construction, storage tanks about 65 meters high, 100.6 meters in diameter, Three C919 airliners can be stacked at the same time, and the tank capacity is equivalent to 614 standard swimming pools, which can store 169 million cubic meters of natural gas."
