河南平頂山生產基地于2019年投產，采用擁有完全自主知識產權的專利技術，在國際上首次將己二酸制造過程中產生的工業尾氣進行回收和純化，主產電子級氧化亞氮。目前產量達到18000噸/年，為全球最大的電子級N2O氣體生產商。該項目具有節能減排、循環經濟、保證安全、降低成本、替代進口等多重優勢，獲得美國保爾森基金會主辦的第四屆可持續發展城市獎“特別提名獎”。
        

        綠菱氣體2024年在安徽阜陽投資興建第二個高純氧化亞氮工廠，2025年正式投產，一期產能可以達到12000噸/年。

      The Pingdingshan production base in Henan commenced operations in 2019, utilizing patented technology with fully independent intellectual property rights. It is the first in the world to recover and purify industrial exhaust gases generated during the production of adipic acid, producing electronic-grade nitrous oxide (N?O). Currently, production capacity has reached 18,000 tons per year, making it the world's largest producer of electronic-grade N?O gas.

      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.
