By strengthening the transmission, heat transfer and mass transfer in the chemical process, the equipment size of the chemical process is greatly reduced, the process flow is simplified, the number of devices is reduced, the unit energy consumption, waste and by-products are significantly reduced, and the purpose of energy saving and consumption reduction in the chemical process is achieved. Our company has rich design experience and industrialization performance, and has successful cases in many large-scale chemical enterprises in China.
As an energy recovery system, the heat exchange network is widely used in oil refining, chemical, metallurgy, pharmaceutical and other enterprises, and plays an important role in reducing energy consumption and improving energy utilization rate of enterprises. However, the energy efficiency of the distillation separation process is only 5%. Therefore, it is of great practical significance to use thermal integration technology to reduce the energy consumption of distillation and reaction distillation systems, and has produced good economic benefits for enterprises.
Reactive distillation organically couples the chemical reaction and the distillation process, which can promote the reaction and separation each other, which can not only significantly improve the reaction conversion rate, but also effectively improve the separation ability. The application of reactive distillation technology not only significantly improves the reaction conversion rate, but also reduces the separation load and energy consumption of subsequent products, and even avoids the complex and energy-consuming azeotropic separation process, and achieves significant economic benefits.
By using the difference of Hanson's solubility constant between adsorbent materials and impurities and the principle of pore molecular identification, the specific selective capture of organic impurities with similar properties can be realized, and the purity of chemicals can be increased from 99.60% to 99.99%-99.999%, and the technical indicators are at the leading level in China.
Based on the high-efficiency double-layer impregnated wire mesh filler, the thermal coupling integration technology and the system closed-cascade precision distillation purification technology are developed, which are applied to the purification process of high-purity electronic-grade chemicals, which saves more than 40% energy compared with the traditional technology, and solves the contradiction between multi-stage distillation and energy consumption.
After years of research and development, it now has high-purity solvents for lithium battery electrolytes, including dimethyl carbonate, methyl ethyl carbonate, diethyl carbonate, ethylene carbonate, propylene carbonate, as well as high-purity electronic grade isopropanol, NMP and other solvent refining and purification technologies, successfully realizing the industrial application of 10,000 tons, breaking the long-term monopoly of foreign technology and breaking through the bottleneck of ultra-high purity chemical production technology.
