The CPC Central Committee and the State Council attach great importance to the development of the Yangtze River Economic Zone. In recent years, General Secretary Xi has made many field visits and made important instructions. Various ministries and commissions have also issued a series of policies and measures to comprehensively promote green manufacturing and reduce the impact of industrial development on the ecological environment. China Chemical Newspaper launched a survey on dyestuff and intermediate industries around the theme of green chemical industry development in the Yangtze River Economic Zone. At the end of the research interview, we will launch a series of reports on dyestuff and intermediates industry research, combing some phenomena and problems found by the research team, and typical practices of some enterprises for the reference of the industry.
Lianyungang & ldquo; 12 & middot; 9 & rdquo; major explosion accident, Yibin & ldquo; 7 & middot; 12 & rdquo; major explosion fire accident, ringing water & ldquo; 3 & middot; 21 & rdquo; three typical safety accidents of extraordinarily large explosion accident, and environmental pollution problems of three chemical parks (Yanwei Port, Duigou Port and Chenjiagang) in Guanhekou, northern Jiangsu, are all related to dyes. Intermediate production is closely related. Safety and environmental protection, this Damocles sword hanging high on the head of dyestuff and intermediates industry, how can it stop falling? In the dyestuff and intermediates industry research of China Chemical Newspaper, a number of key dyestuff enterprises have expressed that they should & ldquo; dredging combination & rdquo; not & ldquo; only blocking & rdquo;.
In July, when the research team exchanged with North Jiangsu, it was found that most of the dyestuffs and intermediates enterprises in the local parks were still in a state of suspension. Affected by the suspension of production, the price of domestic dyestuff intermediates once rolled upward, and the price of dyestuffs also rose. The printing and dyeing industry association of Keqiao District, Shaoxing City, located in the downstream dyeing and printing concentrated areas, even issued an Initiative to jointly resist the abnormal and sharp rise in the price of dyestuffs and chemicals. While domestic supply is tight, the balance of the international market has also been broken. Small-scale intermediates have even become a topic of discussion in the national high-level dialogue. Zhuo Chuang, an information analyst, also said in an exchange with the research team that this situation has sent a good signal to India, an international competitor, to speed up the layout of related products and improve the market competitiveness of its products.
& ldquo; & lsquo; & 3 & middot; & 21 & rsquo; after the big explosion accident, the frequency of special inspection for safety and environmental protection has increased significantly, and the production of dyes and intermediates has stopped and the price has risen, resulting in a serious shortage of some raw materials, which has brought adverse factors to the sustainable and stable development of the industry; in the long run, it has a negative impact on dyes and intermediates. In terms of the competitive environment of the whole industrial chain, the advantages outweigh the disadvantages. However, we hope that our country will be more equal in law enforcement and fairer in law enforcement. & rdquo; said Xu Wanfu, general manager of Zhejiang Runtu Co., Ltd.
On the one hand, because many dyestuff and intermediate enterprises are located in northern Jiangsu, it is difficult to determine the time for their resumption of production; on the other hand, many dyestuff industries, especially intermediate products, involve dangerous processes such as nitration, sulfonation and chlorination, which are under the state's key supervision. Some chemical parks are in the process of approval-ldquo; one-size-fits-all-rdquo; Set it to prohibit access.
Zhao Weiguo, chairman of Jiangsu Jinji Industrial Co., Ltd., told the research team that Lianyungang & ldquo; 12 & middot; 9 & rdquo; explosion accidents, especially the sound water & ldquo; 3 & middot; 21 & rdquo; after the accident, the safety of nitrification process has been raised to an unprecedented high level, even the tendency of nitration reaction is “ one-size-fits-all & rdquo; 。 Nitrification is an indispensable process for the production of dyes, pesticides and pharmaceutical intermediates, while dyes, pesticides and pharmaceuticals are all industries closely related to the national economy and people's livelihood, & ldquo; Elimination & rdquo; nitration process will be a heavy blow to China's dyestuff industry.
In this regard, many top executives of key enterprises have said that dangerous technology can not be & ldquo; only plugging not sparse & rdquo;.
Xu Liguo, deputy general manager of Shandong Changyi Zaohu Salinization Co., Ltd., pointed out that many parks and localities now talk about “ nitrate & rdquo; color change. But in fact, nitrification can also achieve safety and environmental protection, we should be rational.
& Although nitrification process is dangerous as an exothermic reaction, the definition of its danger needs to be distinguished according to the specific process conditions. It has to be admitted that some old nitrification technologies are indeed dangerous processes, but some reactions that are not so dangerous should not be treated differently by ‘ one-size-fits-all ’. In the process of project construction screening, we should first select intrinsically safe processes, and prohibit unsafe processes from starting. In addition, the government should set aside time for enterprises to adjust their transformation and relocation. If the industry is prohibited from production, it will inevitably lead to the lack of commodities in society and the rise of prices, which will lead to some manufacturers who do not have safety regulations to make profits, illegal production, and ultimately bring greater harm. & rdquo; Xu Liguo said.
According to the follow-up of dyestuff and intermediates research group of China Chemical News Agency in recent years, the dyestuff industry has greatly improved in terms of technology upgrading and & ldquo; three wastes & rdquo; treatment. How to guide enterprises to maintain the sustainable development lifeline of safety and environmental protection through the way of “ combination of dredging and blocking &rdquo _________?
As the dyestuff industry is a typical fine chemical industry, industry experts suggest that, taking the fine chemical industry park as an example, the park should promote the treatment of waste salt, waste acid, bulk solid waste and VOCs, classify and implement enterprises in the park, treat both symptoms and symptoms, strengthen the training of employees'knowledge of safety and environmental protection, or through knowledge competition. We should further improve the level of safety and environmental protection awareness, build a green development ecological chain, and implement the concept of environmental friendliness in park planning, spatial layout, energy utilization and resource utilization. YesAs far as enterprises are concerned, the obsolete technology should be eliminated compulsorily and the level of intelligent control of plant automation should be improved. Risk assessment should cover the whole process of process.
In addition, the dyestuff backbone enterprises surveyed unanimously reflect that they hope to improve and refine the industry standards as soon as possible. The fine chemical industry has its particularity, but the relevant government safety management departments mostly apply the relevant regulations and regulations of large-scale petrochemical industry when formulating laws and requirements. Petrochemical industry equipment is generally a large, continuous set of production equipment, starting and stopping steps are long, the process is complex, is a strong systematic operation process. But the fine chemical process and process are basically independent. This has led to many specifications that are not suitable for the fine chemical industry.
Jiang Neng, general manager of Hongguang Special Chemical Co., Ltd. in northern Sichuan, suggested that the supervision and management mode at the national level should be changed to abandon “ one-size-fits-all ” the phenomenon of slow and indiscriminate actions such as disorderly actions, omissions and frequent closures. The phenomenon of excessive actions should be changed from supervision and punishment after the event to pre-guidance and norms, and follow-up understanding and tracking during the event. Concern, after-the-fact persuasion, punishment and other comprehensive control and implementation measures; reduce overlap and cross-examination, the current various countries, industries and local safety inspection, supervision is excessive, some do not have a professional level of inspection so that chemical enterprises are overwhelmed, overwhelmed, tired of coping with, and then to a certain extent affect the production of enterprises.
