Reactor, separator and other chemical equipment is the base of the chemical production process, and it is closely related to the safety, energy consumption and efficiency of the whole process. Overall, the current development trend of the international chemical equipment presents polarization and miniaturization is large.
Large scale equipment mainly for petrochemical or coal chemical process, the current high performance of large chemical equipment in our country is still mainly rely on imports, its R & D and production has been the attention of all walks of life. But in addition to large chemical enterprises, China is also in the tens of thousands of small and medium-sized chemical enterprises, suitable for these small and medium-sized enterprises of small equipment, micro chemical technology should be vigorously developed.
Due to the lack of talent and lack of funds, China's small and medium-sized enterprises generally have the problems of chemical process technology and equipment behind, resulting in low process efficiency, high energy consumption, heavy pollution, poor product quality. In particular, there are many problems in the design of new equipment, process design and process control, and the safety of chemical production process is poor, it is difficult to meet the needs of sustainable development. Can effectively solve these problems, has become China's chemical industry, especially small and medium enterprises to achieve a new type of industrialization and leap forward development of the key.
In the recent 20 years, the development of chemical process intensification technology has injected new impetus and vigor into the related chemical industry. Micro chemical technology with process enhancement and miniaturization, and the heat and mass transfer performance, good safety, easy to process control and direct amplification, can significantly improve the safety and efficiency of production, the rapid advance of the practical process of laboratory results. Because of this, micro chemical technology has attracted great attention of academic and industrial circles, is considered to be a revolutionary technology in twenty-first Century chemical industry.
At present, Bayer, BASF, Switzerland Lonza, American companies such as Corelle have set up a special charge of micro chemical technology department, the development and promotion of the micro chemical equipment products. Some domestic research institutions have made important progress in micro reaction technology. Micro channel response technologies such as the Dalian Institute of development has achieved 80 thousand tons / year of operation, two ammonium hydrogen phosphate in industrial production of 5000 tons of magnesium hydroxide flame retardant test and tons of petroleum sulfonate production demonstration industrial operation test. The National Key Laboratory of chemical engineering and chemical engineering, Tsinghua University, successfully developed a ten thousand ton membrane dispersion micro structure reactor to prepare monodisperse nano calcium carbonate and 150 thousand tons / year of wet process phosphoric acid purification industrial device. All these fully demonstrate the feasibility and superiority of the application of micro chemical technology in industrial scale.
In 13th Five-Year, “ ” period, chemical industry should pay more attention to improve process efficiency, to achieve energy saving, green and safe production, accelerate the breakthrough in equipment miniaturization and micro chemical technology.
In the field of separation can be a priority in two aspects: first, the design of a new type of high efficiency separation efficiency of the distillation equipment and separation of packing; two is to develop a high permeability, high selectivity of the new membrane separation materials. The development and application of new type high efficiency reaction equipment such as micro reactor, super gravity and so on in the field of reactor. For the micro reactor, which focuses on the field of fine chemical industry to carry out demonstration research, such as the traditional chemical technology upgrading (new reaction processes including traditional reaction equipment difficult to achieve), &mdash gas chlorination, nitration, sulfonation, on oxidation, peroxidation, amidation and rearrangement of typical strong exothermic and explosive the liquid and liquid liquid; — reaction process, as well as nanomaterials etc..
“ &rdquo, 13th Five-Year; we need to strengthen the power to overcome the technical difficulties of micro reaction, including micro reaction system optimization design and advanced manufacturing technology, intelligent control technology and micro reactor corrosion and plugging technique etc.. Therefore, it is essential to strengthen the basic research of micro chemical engineering and technology, and to solve the key problems in the field of micro chemical engineering and technology. At the national level, should be added to the enterprise to promote micro reaction technology, as well as other chemical process can be achieved to strengthen the process of safety and energy saving and emission reduction of advanced chemical technology.
The successful development and application of micro chemical technology will have a significant impact on the entire field of chemical and chemical industry. In 13th Five-Year, “ ” period, micro reactor technology is expected in the fine chemical industry, nano materials and micro reaction technology new process based on widely used.
