Under the theme of some scientific issues for emission reduction in process industry, the 363rd Session of Xiangshan Science Conferences was held from 8 to 10 December in Beijing.
In its Framework for Socioeconomic Development during the 11th Five-year Plan Period, Chinese government sets a clear target for cutting energy consumption per 10,000 yuan of GDP. In terms of emission reduction, however, it only sets forth an objective for total emission control of the chemical oxygen demand (COD) and SO2, without due attention to, and exploration of, its energy costs and energy saving mechanism, making it difficult to put this national policy into practice.
While producing over 1/6 of the national GDP, China's process industry consumes more than 50% of the country¡¯s energy source. In addition, as a major source of pollution, the industry includes different sectors producing numerous kinds of pollutants. The difficulty and energy consumption with which these pollutants are addressed are much different. For instance, although low in COD, hard-degradable organic toxicants with very low concentration are extremely hazardous. To treat them would use a large amount of energy.
Due to lack of data concerning energy consumption for controlling various kinds of pollutants, it is difficult to establish a scientific, rational and qualitative index system in this regard so as to evaluate energy saving and emission reduction efficacy of the industry in a really quantitative manner and to work out a scientific solution. This makes it hard to implement the national policy for emission reduction.
To deal with this problem, efforts should be made to combine the process industry with that of new materials and new energy sources by using the approach of chemical engineering thermodynamics. In this way, a systematic model would be set up for evaluating the energy efficiency and emission reduction efforts of various high energy consumption industries and new energy industries, offering scientific criteria for the in-depth studies of energy consumption to deal with complicated and variable pollutants of China¡¯s process industry. Through exploring new ideas for the development of China's traditional industries and the new energy source integrated process industry, scientific evidence will be provided to the government for policy-making.
Keeping this in mind, the 363rd session of Xiangshan Science Conferences convened from December 8 to 10 at the Xiangshan Hotel in Beijing. Under the theme of "scientific issues for emission reduction in the process industry," experts and scholars from various disciplines were invited to have in-depth discussions on the following topics:
1. Energy consumption costs and energy saving mechanism for the treatment of biorefractory organic pollutants;
2. Clean process technologies and resources reuse of high energy-consuming and polluting industries;
3. Key scientific issues for the development of new energy industries;
4. Approaches for evaluating traditional energy-intensive industries in a scientific, objective and quantitative way.
