"In the face of a strong 'environmental storm', the steel industry must consolidate its goals, form a consensus, and unswervingly take energy-saving, emission-reduction and low-carbon development as a strategy and direction, and unswervingly take the road of energy conservation and emission reduction, each Enterprises must not hesitate to pass the environmental protection." This is the mobilization order issued by Zhang Changfu, vice president and secretary general of China Iron and Steel Association, to the steel industry during the “2014 Fifth China Steel Energy Conservation and Emission Reduction Forum”. Relevant leaders from the National Development and Reform Commission, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection have exchanged views with more than 300 representatives on energy conservation and emission reduction policies, countermeasures and experience.
Review: The energy saving and emission reduction of the steel industry is remarkable.
Li Xinchuang, dean of the Metallurgical Industry Planning and Research Institute, used a set of data to illustrate the achievements of the steel industry in energy conservation, emission reduction and carbon emission during the 12th Five-Year Plan period. In the first three years of the “Twelfth Five-Year Plan”, GDP energy consumption and carbon dioxide emissions decreased by 9.03% and 10.68%, and chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides decreased by 7.8%, 7.1%, 9.9% and 2.0%. Li Xinchuang said that the steel industry must achieve the "Twelfth Five-Year Plan" binding target, the situation is grim and the task is arduous.
Li Xinchuang believes that during the "Twelfth Five-Year Plan" period, the steel industry's achievements in energy conservation and emission reduction are manifested in five aspects.
First, the pollutant emission performance indicators have dropped significantly. The energy conservation and emission reduction level of the steel industry has been significantly improved. The sulfur dioxide emissions per ton of steel, ton of steel smoke, the consumption of new water per ton of steel, and the discharge of wastewater per ton of steel have all dropped significantly. A large number of advanced enterprises in clean production, energy saving and emission reduction have emerged.
Second, the rate of compliance with energy-saving limits for each process has been further improved. In 2013, the key statistical enterprises' coking and electric furnace process energy consumption limit value has reached 100%, the sintering process energy enterprise limit value has increased by 7.3%, and the iron and steel process energy enterprise limit value has increased by 1.2%. The limit rate of energy consumption enterprises in the converter process increased by 18.8%.
Third, the energy consumption per ton of steel continues to decline, but the task of completing the energy conservation goal is still lagging behind. In 2013, the key statistical enterprises' total energy consumption per ton of steel was 592 kg of standard coal/ton, down 2.2% from 2010; as of April 2014, it dropped to 590 kg of standard coal/ton; as of April 2014, the completion was completed. 59% of the progress of the 12th Five-Year Plan.
Fourth, the energy efficiency level has been further improved. The specific performance is in three aspects: First, continue to increase the elimination of backward production capacity. In 2011, in 2013, the cumulative elimination of ironmaking capacity was 50 million tons and steelmaking capacity was 46 million tons, achieving energy conservation and consumption reduction from the source, and improving energy efficiency. Second, the level of energy recovery and utilization has been further improved. The utilization rates of high, coke and converter gas have continued to increase; the proportion of self-generation and the recovery of converter gas have increased year by year; the development of facilities to high parameters, large capacity and high efficiency. The third is the deep integration of industrialization and informationization, the improvement of enterprise automation and informationization, and the gradual improvement of enterprise energy management.
Fifth, the use of market mechanisms to promote energy-saving emission reduction effects began to show. First, guide enterprises to save energy and reduce emissions through price changes. Since 2013, we have launched pilot projects on carbon emission reduction in seven provinces and cities, and tried to use market mechanisms to effectively promote energy conservation and emission reduction. Second, the system reform will achieve a win-win situation for energy supply and demand. The nationwide direct purchases of electricity increased from 40 billion kWh in 2012 to 120 billion kWh in 2013. The third is to guide all types of funds into the field of energy conservation, emission reduction and carbon reduction through flexible and varied ways. With the help of the platform of the capital market, through the development of energy-saving and environmental protection industries, the “12th Five-Year” contract energy management model has entered a period of rapid development, effectively alleviating the pressure on corporate funds.
Li Xinchuang said that in order to complete the energy-saving indicators and nitrogen oxide emission reduction targets, it is necessary to adopt structural adjustment, technological progress and intensified management, and rely on legal standards, economic guidance, and necessary administrative means.
At present: The energy saving and emission reduction situation of the iron and steel industry is severe.
“The poor efficiency and scattered enterprise layout will affect the investment of iron and steel enterprises in energy conservation and emission reduction,” said Li Zuojun, deputy director of the Resource and Environmental Policy Institute of the Development Research Center of the State Council.
It is very appropriate to describe the current steel industry with mixed feelings. When China's steel output has become the world's number one for 18 consecutive years, China's steel companies are facing long-term main business losses. According to statistics, since 2012, China has become the world's largest emitter. China's carbon emissions account for 29% of global emissions, the United States accounts for 16%, the European Union accounts for 11%, and currently 65% of global carbon emissions increase annually from China. It is an indisputable thing that China has become a processing factory for industrial manufacturing in developed countries, but the voices of developed countries, including developing countries, that require China to undertake emission reduction obligations are also growing. In order to fulfill its obligations as a responsible big country, the Chinese government solemnly promises that by 2020, the carbon intensity per unit of GDP will be 40% to 45% lower than that in 2005.
Li Xinchuang said that a series of energy-saving emission reduction policies, the improvement and implementation of standard specifications, steel enterprises will face the challenge of multiple assessments of energy consumption intensity, total energy consumption and stricter energy efficiency standards.
The future: the steel industry must face the “environmental storm”
Li Xinchuang proposed that under the new situation, enterprises should adapt to multiple assessment pressures, consider the development of corporate energy strategy; change the conventional energy-saving concept to achieve energy system optimization; Continuously improve energy efficiency; actively respond to greenhouse gas emission reductions; conduct in-depth environmental diagnosis, and implement environmental protection reforms; give full play to energy conservation and emission reduction consultation and technology platform.
Li Xinchuang believes that not the implementation of more energy-saving projects will certainly bring about better energy-saving effects, and should focus on optimizing and optimizing the configuration. For example, the systemicity of technology choice, the effectiveness of technology choices, the rationality of project decisions, and the normative nature of project implementation can play a crucial role in scientific energy use.
According to Zhang Changfu, in 2013, the comprehensive energy consumption per ton of steel for key large and medium-sized steel enterprises has dropped to 591.7 kg of standard coal/ton, a decrease of 14.8% compared with 2005. Indicators such as water use, sulfur dioxide, and smoke dust emissions also dropped significantly. It can be seen that under the circumstances that the external economic environment continues to deteriorate and the production and operation of steel enterprises are difficult, the industry's energy conservation, emission reduction and environmental protection levels are constantly improving.
Zhang Changfu fully affirmed the achievements of the Metallurgical Industry Planning and Research Institute in promoting energy conservation, emission reduction and green development in the steel industry. Zhang Changfu said that the hospital is well-known in the industry and is a powerful research institution. For a long time, they have established a good cooperation and exchange platform for government agencies, steel companies, energy-saving and environmental protection enterprises. Zhang Changfu hopes that with the joint efforts of all of you, the energy saving and emission reduction work of the steel industry will be pushed to a new height.
