Linggas High-Purity Nitrous Oxide (N2O) Pingdingshan Plant Begins Operations

The high-purity nitrous oxide plant in Pingdingshan, invested and constructed by Linggas, will officially begin operations in September 2020. The plant achieves a purity level of 99.9995% and is designed with an annual production capacity of 18,000 tons, with the first phase producing 6,000 tons. This makes it the world’s largest production line for electronic-grade nitrous oxide.

Our strengths:

1. Technological Innovation: Leveraging patented technologies with fully independent intellectual property rights, we have achieved, for the first time internationally, large-scale recovery and purification of nitrous oxide from industrial tail gases containing adipic acid, while ensuring safe and stable large-scale production.

2. Production Safety: This approach abandons the conventional technology for ammonium nitrate decomposition, thereby eliminating various safety risks associated with the procurement, storage, production, and transportation of ammonium nitrate raw materials.

3. Extensive experience: In 2014, Linggas completed the construction of the world’s first industrial-scale facility for the recovery and purification of adipic acid tail gas. After years of operation, the company has accumulated rich production experience, and its products have been recognized by internationally renowned manufacturers in the semiconductor and flat-panel industries, successfully achieving commercial production.

4. Strict quality control: We rigorously implement all requirements of ISO9001 and have established a comprehensive quality control system, with a customer-centric approach to ensure that we meet customer needs.

5. Rapid Supply: We provide customers with comprehensive gas supply solutions and can design tailored gas supply processes based on their varying consumption levels and gas supply requirements.

6. Circular Economy: Effectively reduces greenhouse gas emissions while maximizing the utilization of waste gases, thereby conserving natural resources and energy. This provides a solution for the recovery of nitrous oxide tail gases from adipic acid production facilities, enabling environmental protection and emission reduction, and serving as a model for the circular economy.

7. Reduced Costs: Compared to traditional manufacturing processes, production costs have been significantly reduced, enabling us to offer customers products with higher cost performance and lowering production costs across the entire semiconductor and flat-panel industries.
