蓬萊站 | “法國液化空氣煙臺制造基地”項目：99.999999%！超高純度氮氣背后的技術含量

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

　　法國液化空氣煙臺制造基地項目是世界五百強企業法國液化空氣集團在亞太地區布局的唯一一個高端裝備制造基地項目，也是在國內建設的首個氫能裝備制造基地。項目占地145畝，總建筑面積5.2萬平方米，主要生產空分精餾塔、空分冷箱等高端空氣分離設備及氫能產業相關設備。項目達產后，年可實現銷售收入20億元、稅收2.4億元，產品實現30-50%出口。該項目歷經三個百日攻堅，比計劃提前3個月建成，目前已正式投產。

　　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.

　　項目具備四大特點。一是空分制造能力高。能夠制造全球最大5000噸/天產能的超大型空分設備。二是工藝技術水平高。采用立式雙層徑向流等120多項專利技術生產空氣分離核心裝置，規整填料、吸附純化、低溫精餾和內壓縮流程先進高效。三是分離氣體純度高。項目生產的空分設備可以分離出高純度的氧氣和氬氣，以及ppb級的(十億分之一)超高純度氮氣(純度達到99.999999%)，滿足集成電路和芯片行業嚴苛的氣體純度要求。四是產品運行可靠性高。運用最先進的自動化控制技術，使各單元裝置始終在最佳和最經濟點運行，保障了設備的高穩定性和高可靠性。

　　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.
