蓬莱站 | “法国液化空气烟台制造基地”项目：99.999999%！超高纯度氮气背后的技术含量

　　　Manufacturing Base of Air Liquide Group in Penglai: 99.999999%, the Technical Content behind Ultra-high Purity Nitrogen Gas

　　法国液化空气烟台制造基地项目是世界五百强企业法国液化空气集团在亚太地区布局的唯一一个高端装备制造基地项目，也是在国内建设的首个氢能装备制造基地。项目占地145亩，总建筑面积5.2万平方米，主要生产空分精馏塔、空分冷箱等高端空气分离设备及氢能产业相关设备。项目达产后，年可实现销售收入20亿元、税收2.4亿元，产品实现30-50%出口。该项目历经三个百日攻坚，比计划提前3个月建成，目前已正式投产。

　　This project is the only high-end equipment manufacturing base of Air Liquide Group, a world top 500 company from France, in the Asia-Pacific region, and also the first hydrogen energy equipment manufacturing base built in China. The project covers an area of 145 acres, with a total construction area of 52,000 square meters, mainly producing high-end air separation equipment such as air fractionation distillation tower and air fractionation refrigeration box, and hydrogen energy industry-related equipment. After the project reaches full capacity, it can achieve annual sales revenue of 2 billion RMB and taxes of 240 million RMB, with 30-50% of products being exported. Having been through 300 days of intensive efforts, the project was completed three months ahead of schedule, and has now been officially put into production.

　　项目具备四大特点。一是空分制造能力高。能够制造全球最大5000吨/天产能的超大型空分设备。二是工艺技术水平高。采用立式双层径向流等120多项专利技术生产空气分离核心装置，规整填料、吸附纯化、低温精馏和内压缩流程先进高效。三是分离气体纯度高。项目生产的空分设备可以分离出高纯度的氧气和氩气，以及ppb级的(十亿分之一)超高纯度氮气(纯度达到99.999999%)，满足集成电路和芯片行业严苛的气体纯度要求。四是产品运行可靠性高。运用最先进的自动化控制技术，使各单元装置始终在最佳和最经济点运行，保障了设备的高稳定性和高可靠性。

　　The project possesses four major features.

　　High air fractionation manufacturing capability. It can manufacture ultra-large air fractionation equipment with world’s largest capacity of 5,000 tons per day.

　　High level of process technology. Over 120 patented technologies, such as vertical double radial flow, are used to produce core air separation device. The processes of regular packing, adsorption purification, low-temperature distillation, and internal compression are advanced and efficient.

　　High separation gas purity. The air fractionation equipment produced by the project can separate high-purity oxygen and argon, as well as ultra-high purity nitrogen (with a purity of 99.999999%) at the ppb level (one billionth), meeting the stringent gas purity requirements of the integrated circuit and chip industry. High product operating reliability. By using the most advanced automation control technology, the individual units will always be operating with the most optimal and economical status, ensuring the high stability and reliability of the equipment.
