HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

We are absolutely thrilled to announce the successful commissioning of the 8000/11000 air separation project located in Kunyu, Xinjiang, which was officially put into operation in 2023. This remarkable milestone is not only a testament to the hard work of our engineering and technical team but also a significant boost to the regional industrial ecosystem. Specifically, the project is designed to deliver a steady supply of 8,000 cubic meters of high-purity oxygen and 11,000 cubic meters of high-purity nitrogen per hour—outputs that will directly support key local industries such as coal chemical, metallurgy, and new energy, effectively addressing the long-standing demand for industrial gases in southern Xinjiang and laying a solid foundation for the region’s sustainable economic development.

The seamless operation of this project is underpinned by our scientifically proven and mature air separation technology. The entire process follows a precise, multi-step workflow to ensure optimal efficiency and gas quality. Initially, ambient air is drawn into the system through high-efficiency filters, which eliminate 99.9% of dust, aerosols, and other solid impurities to prevent equipment wear and gas contamination. Next, the filtered air is compressed to a specific pressure by a low-energy centrifugal compressor, then cooled down through a heat exchanger that reuses cold energy from the subsequent separation process—an energy-saving design that minimizes waste. Once cooled to -196°C, the air is converted into a liquid state, which is then sent to a fractional distillation tower. In the tower, liquid air is gradually heated, and since oxygen and nitrogen have distinct boiling points (-183°C for oxygen and -196°C for nitrogen), they vaporize at different stages and are collected separately, ensuring the final products meet ultra-high purity requirements.

Beyond its reliable operational principle, our air separation system boasts a suite of competitive advantages that set it apart in the market. First and foremost is its exceptional gas purity: the oxygen produced reaches over 99.6% purity, suitable for high-demand scenarios like steelmaking and medical applications, while the nitrogen achieves 99.99% purity, ideal for inert gas protection in chemical reactions and electronic component manufacturing. Energy efficiency is another key strength—equipped with an advanced frequency conversion control system and waste heat recovery device, the equipment reduces overall power consumption by 15% compared to traditional air separation units, translating to significant long-term cost savings for users. Additionally, the system features an intelligent monitoring platform that enables real-time tracking of key parameters such as pressure, temperature, and gas output. Coupled with our redundant design for core components, the annual failure rate is kept below 0.5%, ensuring 24/7 uninterrupted gas supply even in harsh industrial environments.

The success of the Kunyu project is no accident—it builds on our over two decades of specialized experience in the global air separation industry. Over the years, we have established a strong track record of serving more than 500 clients across 30 countries and regions, spanning critical sectors including metallurgy (e.g., collaborating with major steel groups in Southeast Asia), chemicals (supporting petrochemical plants in the Middle East), and renewable energy (supplying gases for hydrogen fuel cell production in Europe). Our service model is built around customer-centricity: we start with a detailed on-site assessment to understand unique operational needs, then provide customized solutions from equipment design and on-site installation to personnel training. After commissioning, our global after-sales team offers 24-hour technical support, with spare parts warehouses strategically located in Asia, Europe, and North America to ensure timely maintenance. Whether you are planning a large-scale industrial gas project or need technical upgrades for existing equipment, our team of 200+ certified engineers is ready to deliver professional support. We warmly welcome you to contact us for detailed project cases, technical specifications, or customized solution consultations—let us partner to drive your operational efficiency and growth.If you want to know more information, please contact us freely:
