Steel industry calls for

On July 13, he wenbo, party secretary and executive vice President of China iron and steel association, said on the "2019 (10th) China steel energy conservation and emission reduction BBS" that for the increase of steel industry output, we should pay more attention to whether the clean capacity is enough, and the social incentive mechanism must be directed to those enterprises with advanced environmental protection level.Ultra-low emission is a new starting point for the green development of iron and steel industry. However, there are still many technical problems in the actual implementation, which need to be solved by cooperation and joint efforts within and outside the industry.

More attention should be paid to clean capacity

So far this year, steel industry profits have been disappointing.Statistics show that the industry's profit reached 54.86 billion yuan in the first quarter of 2019, down 36.7% year-on-year.Recently, iron ore prices soared, crude steel production soared, steel prices downward pressure, steel mill profits were further compressed, the first half of this year, steel industry profits are not optimistic.

Statistics show that steel production increased by 37.44 million tons in the first five months, 98% of which was used to meet the domestic steel consumption demand, 2/3 of which was to meet the construction demand.In fact, he noted, one notable phenomenon should be of concern: steel production in the first five months of this year grew 10.2 percent, but steel association members, which account for nearly 80 percent of the country's total steel production, increased 6.2 percent, while non-members increased 23 percent, accounting for 54 percent of the total increase in production.The cleanliness of this growth is worth investigating.

"Our concern is not only whether there is excess capacity, but whether there is enough clean capacity."He stressed that given the demand for steel, the right way to reduce the environmental impact is to give full play to manufacturers that have achieved ultra-low emission standards while limiting production capacity with high emissions.

Implement "differentiated management"

In the government work reports of the state council in 2018 and 2019, it was clearly proposed to accelerate the transformation of the steel industry to ultra-low emissions.However, in the context of the declining profits of the steel industry, a large amount of capital investment is still needed to push forward the transformation of ultra-low emissions, which is bound to increase the burden on enterprises.

"Governments at all levels are stepping up inspections and inspections.So far this year, we have invested billions of yuan in the transformation of ultra-low emissions, and will continue to invest, but the profit is still decreasing. In June this year, our profit per ton of steel fell to about 100 yuan, and even less since July.""Our company is just like other companies," an official from a large steel company in hebei told the China securities journal.

He wenbo pointed out that the utilization rate of production capacity is an economic issue, while the actual emission level is an environmental and ecological issue."Some steel enterprises that invest a lot in environmental protection report that in order to achieve ultra-low emissions, their environmental protection operating costs have reached 260 yuan to 270 yuan per ton."He wenbo said the implementation of ultra-low emissions is a necessary measure for the green development of the steel industry, and phased production limits in some areas are also a necessary protective measure at the current stage of development.In the process of forced production limits, it is crucial to implement "differentiated management" for enterprises with different levels of environmental protection. The regulatory mechanism must encourage innovators and protect advanced productivity.

Liu bingjiang, director of the department of atmospheric environment at the ministry of ecology and environment, echoed he's view. He said the steel industry should be differentiated in heavy pollution weather management, and companies should be classified into A, B and C levels according to their process equipment, treatment measures, organized emission limits and transportation modes.Companies that achieve ultra-low emissions are classified as A, while others are classified as B and C."A-level enterprises are limited or not limited, and c-level enterprises are limited. There is A gap between different levels of emission reduction measures.We will allow enterprises that invest more in environmental protection to enjoy benefits and avoid losses. We will encourage the best to eliminate the worst and reward the best to punish the worst, thus creating a level playing field for good to drive out bad."

Green development requires concerted efforts

In April this year, the ministry of ecology and environment and five other ministries and commissions jointly issued the opinions on promoting the implementation of ultra-low emissions in the steel industry (hereinafter referred to as the opinions), which not only sets clear requirements for ultra-low emissions after end-treatment, but also calls for strengthening pollution control in the whole process, the whole system and the whole industrial chain.

Emissions from the steel industry are still huge.Data show that in 2018, sulfur dioxide, nitrogen oxide and particulate matter emissions from China's steel industry totaled 1.06 million tons, 1.72 million tons and 2.81 million tons respectively, accounting for about 7%, 10% and 20% of the country's total emissions of major pollutants.Iron and steel enterprises in the beijing-tianjin-hebei region and its surrounding areas, the Yangtze river delta and the fen and wei plains account for 30%, 21% and 4% of the country's total production capacity respectively, with a total of 55%.The production capacity of the top 20 cities (12 key regions) accounted for 51% of the country's total production capacity, with an average PM2.5 concentration of 50 micrograms per cubic meter, 28% higher than the national average.

"At present, more than 60 enterprises in key areas of the steel industry are implementing ultra-low emission transformation, with a total crude steel production capacity of about 260 million tons."Liu bingjiang said the transformation of ultra-low emissions of steel should be carried out step by step, not in step.New reconstruction and expansion projects (including relocation) shall be constructed at a high level in accordance with ultra-low emission targets.By the end of 2020, 60 percent of the existing steel capacity in key regions, or 340 million tons, will be upgraded.By the end of 2025, the remaining production capacity in key regions (150 million tons) and large and medium-sized steel enterprises in non-key regions (270 million tons) will have basically completed the transformation of ultra-low emissions.

He wenbo said ultra-low emissions are a new starting point for the green development of the steel industry.Upgrading and upgrading of ultra-low emissions will bring about a green development revolution of investment scale, r&d and innovation, and the whole process and industrial chain of steel manufacturing system.This will inevitably require and facilitate us to further innovate technology and improve management level. It will also lead to revolutionary changes in the traditional steel manufacturing industry.

However, in his view, the "opinions" related requirements represent the global steel industry in the era of the most stringent emission targets and requirements for ecological protection.However, there are still many technical problems in the implementation.

"For example, time is needed to verify whether flue gas desulfurization, denitrification and dust removal technologies can reach ultra-low emission standards in a long-term and stable manner.Desulfurization of blast furnace gas essence and other technologies still need to be innovated and broken through, which requires the cooperation and joint efforts of both inside and outside the industry.He wenbo introduces, in investigation process, the innovation that also hears a lot of enterprises to reflect management new technology and application have difficulty and risk quite quite, transform investment huge, run cost is high.

The steel company officials also said it is urgent to work out a scientific, reasonable and stable standard to reduce the waste of enterprise and social resources as we push forward the transformation of ultra-low emissions in the steel industry.

Planning institute party committee secretary, director li xinchuang metallurgy industry, said the ultra-low emissions by up to existing technical corresponding emission limit value as ultra-low emission limit value to determine the basis, so not happen again in the future a period of time changes, the selection of the focus of the enterprise management process puts forward very high requirements, should be "one pace reachs the designated position".

He further said that in the long run, the implementation of ultra-low emissions reform will help promote green development of the steel industry and win the battle to protect the blue sky.Therefore, the steel industry must be responsible and responsible in promoting ultra-low emission upgrading and green development.
