河南平顶山生产基地于2019年投产,采用拥有完全自主知识产权的专利技术,在国际上首次将己二酸制造过程中产生的工业尾气进行回收和纯化,主产电子级氧化亚氮。目前产量达到18000吨/年,为全球最大的电子级N2O气体生产商。该项目具有节能减排、循环经济、保证安全、降低成本、替代进口等多重优势,获得美国保尔森基金会主办的第四届可持续发展城市奖“特别提名奖”。
绿菱气体2024年在安徽阜阳投资兴建第二个高纯氧化亚氮工厂,2025年正式投产,一期产能可以达到12000吨/年。
The Pingdingshan production base in Henan commenced operations in 2019, utilizing patented technologywith fully independent intellectual property rights. For the first time globally, it recovers and purifies industrial waste residue gas generated during the production of adipicacid to produce electronic-grade nitrous oxide (N2O). It is currently the world’s largest producer of electronic-grade N2O gas ,with an annual production capacity of 18000 tons.The project boasts multiple advantages, such as energy conservation, emission reduction,circular economy, enhanced safety, cost reduction, and import substitution. It was awarded the “Special Nomination Award” at the 4th Sustainable City Award, sponsored by the Paulson Institute.
In 2024, Linggas invested in the construction of its second HPG N2O plant in Fuyang, Anhui. The plant is scheduled to begin operations in 2025, with a Phase 1 production capacity of 12,000 tons per year.
