Jiangsu Nine Heaven High-Tech Co., Ltd. is located in Nanjing Pukou Economic Development Zone, established in December 2011. It is a national high-tech enterprise integrating scientific research, production, sales and service.

Relying on the Institute of Membrane Science and Technology of Nanjing University of Technology, Jiutian High-tech has established a close industry-university-research cooperation. It has a technology research and development team LED by academicians and chief scientists of the national "973" project. Among them, the company has 4 doctors and 20 masters. The company focuses on the research and development, production and sales of pervaporation membrane separation technology and products, which are used for organic solvent dehydration in chemical, pharmaceutical, electronic, energy and other industries. Compared with the traditional separation technology, the new pervaporation membrane separation technology can achieve fine separation at the molecular level, saving energy by more than 30% to 50%, which is a typical energy-saving and environmental protection technology, and is known as the "crown pearl" in the field of separation technology ".

At present, only Germany GFT-IKTS and Japan Mitsui Shipbuilding two companies can provide molecular sieve pervaporation membrane dehydration of commercial products. Through years of research and development, Jiutian Gaoke has taken the lead in realizing the industrialization of NaA-type molecular sieve pervaporation membrane in China, with a market share of 61% in the pharmaceutical industry. The company has undertaken more than 20 major provincial and ministerial-level special projects, such as the national 863 project, the transformation project of scientific and technological achievements in Jiangsu Province, and the industrial transformation and upgrading project in Jiangsu Province. It has a number of international advanced pervaporation membrane separation technology, independent intellectual property rights and proprietary core technology, applied for more than 130 patents and authorized nearly 100 patents, including 33 invention patents and 6 software copyrights.
