Abstract：“Transference processes and reaction engineering” is the disciplinary basis of process industry and process engineering, which provides an important theoretical guarantee for the modernization of process engineering research and design.In recent years, due to the characteristics of China process industry, resource and environmental problems have become prominent.In order to solve the energy and environmental problems, the ideas of "transference processes and reaction engineering" and "three circle one net" with complementary and synergistic effects were put forward, hoping to fundamentally solve the resource, energy and environmental problems arising from the process industry.The socalled "three circle" refers to the new technology meets the environmental requirements (one circle); material and energy realize the circulation (two circles) within the industry and equipment; resources and energy realize the circulation (three circles) and matching of the whole society, crossindustry and crossregion. “one net” refers to the construction of coalbased clean gas energy network to achieve selfsufficiency of clean energy and ensure energy security in China.Coal is the main energy source in China. The direct utilization of coal has resulted in energy waste, air pollution and water pollution. Therefore, the clean and efficient conversion of coal, as a necessary energy source, coal is fundamentally to achieve clean and efficient transformation.Blast furnace is an important equipment in iron and steel industry. In recent years, some blast furnaces are facing the risk of demolition due to the problems of excess capacity of crude steel, scrap recycling and difficulty in repaying capital investment, which will inevitably lead to waste of fixed assets. Therefore, how to find a way out for large and mediumsized blast furnaces is a realistic problem in front of the iron and steel industry. Besides ironmaking, the functions of energy conversion and solid waste conversion of blast furnaces have not been brought into full play. Therefore, the blast furnace into a gasification furnace to coal gasification in the blast furnace were proposed to transform, and use gas purification technology and waste heat recovery technology to achieve clean conversion of coal, and finally form a clean gas energy network. The process industries, especially the energy industry and heavy industry, with the help of “transference processes and reaction engineering” and “three circle one net” concept were hoped to develop. To make China iron and steel industry develop from output first to equipment function upgrading, equipment upgrading and product structure expansion.To upgrade industry, break through industry barriers, realize the transformation of excess iron and steel to coalbased clean energy, and help the process industry "overtake in bends".
