Company profile
Henan Xinlianxin Shenleng Energy Co., Ltd. has worked in the gas industry for more than 40 years and integrates R&D, production, transportation, sales and service. Its five production bases are located in Xinxiang in Henan, Manas in Xinjiang, Jiujiang in Jiangxi, Wuyang in Henan and Guigang in Guangxi. The company was listed on China’s New Third Board in October 2014 under stock code 831177. Its product portfolio includes high-purity and electronic-grade carbon dioxide, electronic-grade carbon monoxide, high-purity methane, high-purity carbonyl sulfide, electronic-grade sulfur dioxide, ultra-pure ammonia, standard gases, mixed gases, rare gases and dry ice. The company serves machinery manufacturing, chemical production, food processing, photovoltaics and semiconductor industries with gas products and one-stop solutions. Products are described as exported to nearly 20 countries and regions including Japan, Korea, Australia, the Middle East and Southeast Asia. R&D infrastructure includes a Henan provincial enterprise technology center, a Shanghai R&D center, a CNAS laboratory and engineering technology centers for fertilizer-tail-gas resource utilization and cryogenic gas separation. The company states that it has undertaken seven national, provincial or ministerial science and technology programs and holds more than 100 national patents. It has led or participated in preparation of 11 national standards covering products including electronic-grade CO2, CO and COS. Its coal-chemical tail-gas resource-utilization work has received first-, second- and third-prize Henan Science and Technology Progress Awards. The CNAS laboratory is listed at 1600 square metres and uses instruments including helium-ionization gas chromatography, moisture meters, oxygen analyzers and ICP-MS for specialty-gas analysis. The company lists ISO 9001, ISO 14001, ISO 45001, FSSC 22000 and GB/T 23001 management-system certifications within its full-lifecycle quality-management framework. Its R&D model combines independent development with external cooperation and is organized around core-technology research, high-end product development and process optimization. The company’s strategy distinguishes scale development in bulk gases from stronger R&D in specialty gases and places electronic specialty-gas localization among its development directions. Its national production-base network, in-house food-grade transport fleet and multi-source operating model are used to support continuous gas supply for customers with different volume and purity requirements.
Exhibits
The gas portfolio spans specialty gases, food and medical gases, bulk gases, standard gases and mixtures and hydrogen energy, with supply formats selected for different customer consumption patterns. For high-consumption sites, the company offers installation, operation and maintenance of on-site gas-generation equipment, while industrial parks can receive continuous oxygen, nitrogen, carbon monoxide and other gases through dedicated pipelines. Large-volume users can receive liquid oxygen, liquid nitrogen and liquid carbon dioxide by dedicated low-temperature tank trucks, while mobile or lower-volume customers can use cylinders, Dewar flasks or container tanks. High-purity methane is positioned for semiconductor CVD, epitaxial growth and etching or cleaning processes. The methane route uses proprietary cryogenic distillation to remove trace moisture, oxygen, nitrogen and hydrocarbons and is described as reaching stable 6N purity. The company operates two air-separation units rated at 80,000 Nm3/h each, providing feedstock for bulk gases and downstream rare-gas extraction. Rare-gas production combines cryogenic separation with chemical purification to recover and refine gases from air into higher-value specialty products. High-purity neon is specified at 99.999 percent, or 5N, with annual capacity of 110,400 Nm3 and is used as a working medium for lithography-machine lasers. The 5N neon system is stated to have commenced operation in April 2024. Ultra-high-purity ammonia reaches 99.99999 percent, or 7N, for photovoltaic and semiconductor manufacturing and has annual production capacity of 5,000 tons. The 7N ammonia production line is also stated to have been commissioned in April 2024. Electronic-grade carbon dioxide is supplied for semiconductor processes including chip cleaning, photoresist development and Chemical Vapor Deposition. The electronic-grade CO2 facility is listed at 10,000 tons per year and uses multi-stage fractional distillation and deep purification to control moisture, oxygen, hydrocarbons and metal ions. The resulting electronic-grade CO2 is described at 5N to 6N purity, compliant with SEMI international standards and certification requirements of mainstream wafer fabs. The specialty-gas catalog lists carbon monoxide at 99.5 to 99.999 percent for chemical, metallurgical, pharmaceutical-synthesis, semiconductor, monitoring and research applications. Methane is listed at 99.9 to 99.9999 percent for applications including semiconductor use, fuel and chemical feedstock. Electronic-grade carbon dioxide is listed at 99.999 and 99.9999 percent for electronics, semiconductor manufacturing, flat-panel displays and photovoltaic cells. Sulfur dioxide is available at 99.9, 99.99 and 99.999 percent for uses including integrated-circuit manufacturing, while carbonyl sulfide is listed at 99.9 and 99.99 percent for chemical, semiconductor and petrochemical applications. The catalog also lists ultra-high-purity oxygen at 99.999 and 99.9999 percent for photovoltaics, panels, LEDs and integrated circuits. Krypton is supplied at 99.999 and 99.9999 percent for electronics, lighting, laser, medical and semiconductor uses, and xenon at 99.999 to 99.9999 percent for lighting, semiconductor, LCD, medical and aerospace applications. Neon is listed at 99.999 percent for applications including electronics, laser technology and cryogenic cooling, while helium is listed at 99.999 and 99.9999 percent for aerospace, nuclear, research, advanced manufacturing and medical fields. Hydrogen is listed from 99.97 to 99.9999 percent and is used as a clean-energy source and raw material in chemicals, automotive fuel, semiconductors and LEDs. At normal temperature and pressure, the hydrogen page describes H2 as colorless, odorless and highly flammable and only sparingly soluble in water. Hydrogen density is listed as 0.089 g/L at 101.325 kPa and 0°C, approximately one fourteenth of the density of air. The hydrogen page places the gas within the company’s specialty, food and medical, bulk, mixture and hydrogen-energy product structure rather than treating it as a stand-alone supply category. The solution page describes on-site gas production, pipeline supply, bulk-liquid delivery and cylinder or Dewar supply as four distinct delivery modes chosen according to consumption level and operating conditions. The same solution framework links installation and operation of customer-site generation equipment with dedicated pipelines, cryogenic tank-truck logistics and portable container formats. Semiconductor customers are served with ultra-high-purity gas products and services intended to meet strict requirements for purity and stability and support yield and process reliability. Photovoltaic applications use high-purity specialty gases with the stated goals of improving yield and cell efficiency and reducing cost. Other application fields include food and pharmaceuticals, petrochemicals, metallurgy and machinery manufacturing, hydrogen energy and environmental protection. Environmental services cover waste-gas and wastewater treatment, gas detection, atmospheric monitoring and pollution-source monitoring and include carbon-dioxide recovery projects. The company provides application guidance, gas-solution consultation, periodic on-site facility inspection and maintenance, gas-safety training and technical services through its professional service team. Its supply model combines gas sources from multiple production bases with a single-point multi-source operating approach to maintain continuous product availability. Quality control covers R&D, production delivery and after-sales service within a full-lifecycle quality-management system, while a separate safety-management system is used for process-safety and risk control. The R&D platform combines independent research and external cooperation, five listed system-building areas, national standards, patents and CNAS analytical capability to support high-purity and electronic specialty gases. The overall semiconductor-facing supply therefore links upstream air separation, rare-gas recovery, deep purification and laboratory analysis with named electronic gases for lithography, CVD, cleaning, photoresist development, epitaxy and other manufacturing steps.
