Recently, the results of the 23rd China Patent Award were announced. Jiangsu Jiutian High-tech Co., Ltd. (hereinafter referred to as Jiutian High-tech) won the China Patent Excellence Award for its invention patent "A Process and Device for Improving the Yield of Isopropanol Produced by Acetone Hydrogenation (ZL 201310364054.1)!
The China Patent Award is the highest award in the field of patents in my country. It is co-sponsored by the State Intellectual Property Office and the World Intellectual Property Organization. It is the only government department award in my country that specifically rewards inventions and creations granted patent rights. It mainly considers the technical advancement of patents., Application and protection measures, social benefits and development prospects and other related qualities.
The winning patent relates to a process for increasing the yield of isopropanol from the hydrogenation of acetone. In the process of acetone hydrogenation to produce isopropanol, isopropanol, water and acetone are easy to form a ternary azeotrope, which is directly sold as waste liquid after dehydration and separation by traditional azeotropic distillation, extractive distillation and other processes, resulting in a lower yield of isopropanol and high production costs.
Through continuous technological innovation, Jiutian Gaoke introduced pervaporation membrane separation technology in the process of acetone hydrogenation to produce isopropanol. The membrane permeation method was used to dehydrate the mixed components of isopropanol, acetone and water, so that acetone was refluxed to the previous reactor to participate in the hydrogenation reaction, thus solving the ternary azeotropic problem formed by isopropanol, water and acetone, and greatly improving the acetone conversion rate and isopropanol yield!
Process flow is shown as follows:
▲Complete equipment for pervaporation membrane
The patented technology realizes the process reengineering of acetone hydrogenation to produce isopropanol, optimizes the production process of isopropanol, the process is simple and easy to operate, reduces production energy consumption and cost, reduces carbon emissions, improves the yield of isopropanol, and the process does not introduce the third component, avoiding environmental pollution. Many sets of industrial equipment have been established in Jiangsu, Shandong and other places. Compared with traditional processes such as azeotropic distillation and extractive distillation, the water in isopropanol can be separated more effectively, the conversion rate of acetone can reach 99.9, and the yield of isopropanol can reach 99.5.
As the first national high-tech enterprise in China to realize the research and development, production, sales and service of inorganic pervaporation membranes, Jiutian Hi-Tech focuses on the design, delivery and service of organic solvent separation solutions with membrane products as the core. The company has always been around the core patent technology, continuous research and development, and gradually realized a number of separation technology industrialization and large-scale promotion and application!
