Chemical engineering is penetrating into many fields - Sidelights on seminars on the development strategy of chemical engineering and industrial chemistry
Under the impetus of the rapid development of modern science and technology, chemical engineering disciplines are undergoing profound changes in academic connotations and research objectives in recent years. At the same time, they are also expanding their application fields and infiltrating fields such as biology, materials, and the environment. At a seminar on strategic development of chemical engineering and industrial chemistry held in Yinchuan recently, the participating experts reached a consensus. Facing the needs and challenges of the chemical industry, the new scientific concept and knowledge system has become a strong driving force for chemical engineering and will be The 21st century has played an important role in the national economy. In view of chemical engineering being broadened from the study of conventional systems to the study of unconventional and extreme processes, Professor Zhu Ziqiang of Zhejiang University believes that at least the following two aspects can be considered: First, the process is subject to extreme operating conditions such as high temperatures, Chemical process and chemical unit operation under high pressure or low temperature, transfer process, separation process, chemical reaction process under supercritical conditions, and phase behavior and phase equilibrium and hydrothermal synthesis of binary and multicomponent systems near the critical point, The process under simulated geological conditions, etc. Second, the overall nature of the material and its nature on the nanometer and micrometer scales will have more differences. The nanometer and micrometer materials have many superior performances and are happy to be adopted by all walks of life. The key lies in the ways to obtain the particles of various materials. Therefore, the research contents of such projects are reciprocally interdisciplinary and urgently need to be solved. Professor Zhu Ziqiang pointed out that the basic theory of chemical engineering established over a long period of time is a valuable asset, but it is still difficult to solve the chemical engineering and industrial chemistry problems under extreme conditions, and it needs to accumulate and innovate in research practice. Identify new methods that are suitable for effectively guiding the solution of chemical engineering and industrial chemistry under extreme conditions. Some may also draw lessons from research results and theories in chemistry, mathematics, physics, and biology to accelerate the innovative development of chemical engineering theory. Spiral rise. At present, on the global scale, the boundaries between chemical and chemical engineering have become increasingly blurred. Many experts at the meeting believe that our country should also try to blur this concept. Chemical and chemical engineering studies on the transformation of substances and their processes are one of the important foundations of the national economy. Chemistry is the study of the laws of chemical reactions of substances, the discovery of new reactions, the creation of new processes, and the regulation of processes by chemical plants, enabling the existing processes to be realized in engineering, ensuring that the reaction conditions and environment in the entire reaction system can be Meet the process requirements. Material transformation must go through processes, processes, and engineering to achieve industrialization. Therefore, chemistry and chemical industry together create a variety of related process industries. The combination and mutual penetration of chemical engineering and life sciences, materials science, information science and other high-tech fields will create creative breakthroughs in basic research and engineering applications. In terms of research methods and methods, it focuses on the integration and interpenetration of multiple disciplines and proposes creative research methods to promote the development of basic theories of chemical engineering. Prof. Xu Nanping of Nanjing University of Technology proposed to explore the topic of material chemistry engineering practice. There are three main research directions: interface and molecular simulation, chemical engineering research in material design and preparation, and material-based process engineering and integration technology. The basic research idea is: through molecular modeling and necessary experimental research, the relationship between the structure, performance and preparation of materials, and the process simulation of process design, production and processing are revealed within the scope of molecular and mesoscopic dimensions. It lays a theoretical foundation for application; introduces the theory and method of chemical engineering into the design and preparation of materials, and solves the design and preparation of important new materials in the process industry through chemical engineering studies of functional-microstructure-preparative quantitative relationships. The formation and application of the new materials industry lays the foundation for theory and technology. Based on theoretical research results, based on the development of new materials, combined with the country's major needs, through the process integration and process optimization, the formation of independent intellectual property rights, the national economy Significant results with significant impacts, to achieve the direct contribution of theoretical research to social development. Researching and developing green technologies and technologies and protecting the ecological environment are the tasks and goals for the continuous development of chemical science and technology. Professor Jin Yong, an academician of the Chinese Academy of Engineering, presented the concept of eco-chemical engineering. At present, sustainable development is an urgent task that is widely concerned, and research and development of advanced science and technology that breaks through conventional thinking patterns are the basis for the development of a circular economy. In the design of new products and the research and development of new technologies, traditional industry restrictions should be broken down and production should be organized according to the principles of natural ecology. For example, the phosphorus industry is an important bulk chemical production process in China. In the past, whether yellow phosphorus or phosphate fertilizer production would bring serious environmental problems, extending the industrial chain through research and development of link technologies can fully utilize resources. In this way, pollution is eliminated and obvious economic benefits are obtained.
