Jiangsu Long Membrane Hi-Tech Co., Ltd. has been officially recognized as a national-level Specialized, Sophisticated, Distinctive and Innovative “Little Giant” Enterprise by the Ministry of Industry and Information Technology of the People’s Republic of China.
Valid from July 1, 2024 to June 30, 2027, this recognition reflects the company’s specialized expertise, technological innovation and development potential in the field of high-performance membrane materials and membrane-separation solutions.
National-Level Specialized, Sophisticated, Distinctive and Innovative “Little Giant” Enterprise
Built on Long-Term Membrane Research
Jiangsu Long Membrane is supported by the Institute of Membrane Science and Technology at Nanjing Tech University. The company focuses on the research, production and application of high-performance membrane materials, while integrating equipment design, system manufacturing, complete solution development and market services.
The company’s technology journey can be traced back to 2005, when Professor Jin Wanqin’s team began researching advanced membrane materials. A core patent was granted in 2009, followed by the successful construction of tubular and flat-sheet membrane pilot lines. In 2016, scaled production lines with annual capacities of 50,000 square meters of tubular membranes and 100,000 square meters of flat-sheet membranes were established.
From Scientific Research to Industrial Solutions
Our development is guided by a clear principle: stay close to science and stay close to engineering. By connecting material innovation with real industrial requirements, we transform membrane research into practical and scalable separation solutions.
Proven Engineering and Application Capabilities
In 2014, the team delivered China’s first demonstration project using membrane technology for VOC recovery and treatment. This was followed by further breakthroughs in solvent recovery, azeotropic-mixture separation and production-process optimization for the beverage industry.
The company has accumulated more than 350 engineering cases across VOC recovery and treatment, liquor-production process transformation, azeotrope separation, oxygen-enriched combustion, membrane-based dust-removal systems and wet electronic chemical purification.
Its membrane-separation technologies serve customers in new energy, integrated circuits, biopharmaceuticals, petrochemicals, food processing, liquor production and functional beverages. Project experience includes cooperation with major enterprises such as Sinopec, CNOOC, Sinochem, SEMCORP, Gusu Food, King’s Luck Brewery and CITIC Guoan Wine.
Innovation Recognized at the National Level
Jiangsu Long Membrane is also recognized as a National High-Tech Enterprise, a Jiangsu Gazelle Enterprise, a Nanjing Gazelle Enterprise and a Nanjing Leading Technology Enterprise. The company and its supporting technology team have received honors including the Second Prize of the National Science and Technology Progress Award and the First Prize for Technological Invention from the China Petroleum and Chemical Industry Federation.
The company’s solvent-recovery membranes and related technologies have also been technically appraised as reaching an internationally advanced level. These achievements demonstrate a sustained ability to connect fundamental research, membrane-material development, equipment engineering and commercial implementation.
Advancing Membrane Technology for Future Industries
The national-level “Little Giant” recognition represents both an important achievement and a new starting point. Jiangsu Long Membrane will continue advancing industrial applications in carbon dioxide capture, hydrogen separation, olefin monomer recovery, low-concentration solvent recovery, organic azeotrope separation, natural-product extraction and wet electronic chemical purification.
Through focused research, responsible engineering and close cooperation with customers, we will continue delivering efficient membrane-separation products and integrated solutions for demanding industrial applications.
