Problems existing in industrial development
The particularity of the dye and dye intermediates industry determines In view of the high dependence of production on water resources and the consideration of product transportation costs, companies are mostly located along rivers and seas, and the “chemical industry along the river” was formed. Over the years, the development model that is unscientific, unenvironmental, and eager for quick success and quick success has caused the dye and dye intermediate industry in the Yangtze River Economic Belt to accumulate some backward production capacity. This is mainly reflected in the environment of the Yangtze River Economic Belt’s dye intermediates-dyes-textile printing and dyeing industry chain. Concerns about protection and production safety still exist. Judging from the research, there are still many areas for improvement in the dye and intermediate companies in the Yangtze River Economic Belt.
Two levels of production safety status
Dye and dyes in the Yangtze River Economic Zone The dye intermediates industry research team found during on-site visits and surveys that although most companies have significantly improved their device safety and intelligence levels through technological transformation and process improvement, the overall safety level has reached a new level. However, there are still some companies that follow extensive production methods, and the polarization of dye and dye intermediate companies in the Yangtze River Economic Zone in terms of production safety has become increasingly obvious.
A group of advanced enterprises continue to strengthen safety research and update technology to provide preventable and controllable scientific guarantees for production. For example, Longsheng Research Institute uses reaction calorimeter to evaluate the safety and risk of chemical processes, which can effectively prevent and control accidents caused by sudden interruption of the cooling system and a sharp increase in reaction heat due to sudden power outages, misoperations and other special circumstances. explode. However, the research team also found that in the face of rapidly expanding market demand, some companies failed to establish and practice the concept of green development, failed to maintain the bottom line of safe development, crossed the red line of safety production, and indifferent to intrinsic safety and environmental friendliness. In 2019, the “March 21” extremely large explosion accident at Xiangshui Tianjiayi Company killed 78 people. In 2018, Yibin Hengda Technology Co., Ltd. suffered a major explosion and fire accident on “7·12”, killing 19 people. In 2017, the “12·9” major explosion accident at Lianyungang Juxin Biotechnology Co., Ltd. killed 10 people. These safety production accidents not only caused huge losses to the lives and property of the people, but also seriously affected the image of the dye and dye intermediate industry. The achievements of advanced enterprises in safety production construction were submerged in the dark clouds of these explosions.
The level of environmental protection shows a trend of downstream>midstream>upstream
At present, The overall environmental protection level of the dye and dye intermediate industry in the Yangtze River Economic Belt shows a trend of downstream > midstream > upstream. The most typical ones in the lower reaches are Zhejiang and Shanghai. Runtu Co., Ltd. has invested more than 1.5 billion yuan in environmental protection in recent years, focusing on process improvement and “three wastes” treatment. Through process transformation, it has eliminated high-pollution, high-energy consumption, and high-emission products, and the emissions of various wastes have been significantly reduced. Taizhou Qianqian Chemical Co., Ltd., a subsidiary of Haixiang Pharmaceutical, has overcome the problem of salt-alkali resistance of reactive brilliant blue KN-R, achieved effective recovery of solvents, and significantly reduced wastewater emissions.
The industrial technology level in the middle and upper reaches of the Yangtze River is relatively backward, and the environmental protection level is uneven. There are not only problems such as process pollution, but also involve a series of problems such as water transportation, affecting ecological waterways. of construction. For example, Yibin Hengda Technology Co., Ltd. introduced fine chemical products and rushed into production without basic production conditions, causing a major safety accident that killed 19 people. After the accident, the company’s illegal sewage discharge situation came to the public attention. The lack of corporate self-discipline, weak environmental supervision by government departments, inconsistent law enforcement standards, and low costs of environmental violations are the main reasons why dye and dye intermediate companies in the middle and upper reaches of the Yangtze River have frequent ecological and environmental problems, and the environmental protection level of companies lags behind those of companies in the lower reaches of the Yangtze River.
Some backward production capacity will be transferred to areas with weak supervision
With the recovery The Yangtze River ecological battle and the entry of chemical companies into the park are continuing to advance, and a large number of chemical companies are relocating. In this process, the backward production capacity of the dye and intermediate industries has been transferred to the west, north, and to towns. Following Ningxia and Inner Mongolia, Jilin and Heilongjiang in the northeast, Gansu, Qinghai and even Xinjiang in the northwest have become important target areas for new projects of dye and intermediate companies.
During the visit, the investigation team found that some companiesFormulate precise law enforcement rules (or systems) under the �》, further clarify operating rules and standard scales, reduce discretion as much as possible, and effectively standardize law enforcement behaviors; strengthen law enforcement capacity building, continuously improve law enforcement conditions and equipment, and promote the standardization of environmental supervision capabilities . It is recommended to strengthen the investigation of “loose and polluting” enterprises; improve the transparency of corporate environmental information disclosure, and establish a list of untrustworthy enterprises; the local government gradually transforms “investment attraction” into “investment selection” and establishes an industrial undertaking environmental assessment system, starting from natural resources, Geographical location, environmental capacity, economic foundation, economic structure, market capacity, environmental risks and other indicators are comprehensively considered to ensure that the introduced industries serve the local economy on the premise of meeting ecological requirements.
Sixth, we advocate mergers and reorganizations to maintain market stability.
Mergers and reorganizations are expected to become an effective way to reform the supply-side structure of the dye and intermediates industry and achieve high-quality development. Now is the brewing period of the “14th Five-Year Plan”. Industry development requires planning first. This is also the source guarantee for the green development of the dye and intermediate industry. Through the formulation of scientific and reasonable plans, the dye and intermediate industry can be guided to achieve green and green development. Sustainable development is an important and necessary task. To this end, it is recommended that the national macro-decision-making department further improves policies and measures to promote the transformation and upgrading of the dyes and intermediates industry, and coordinates the high-quality development layout of the dyes and intermediates industry. Timely revise and publish the national industrial structure adjustment guidance catalog and the catalog of outdated safety technology and equipment, resolutely close and exit those that do not meet the requirements, curb blind, disorderly and illegal development, promote the transformation and upgrading of industries to high-end, eliminate backwardness, vacate the cage and replace the bird, Realize the conversion of old and new driving forces and improve the overall development level of the industry. Encourage leading enterprises to merge and reorganize backward enterprises, improve the process technology and intrinsic safety of backward enterprises, build a green development ecological chain, prevent sudden changes in output and maintain market stability with stable growth and high quality.
The seventh is to jointly cultivate professional and technical talents.
In order to adapt to the rapid development of the dye and dye intermediate industry and meet the strong demand for dyes and intermediates in the domestic and foreign printing and dyeing textile markets, the first priority is to pay close attention to the safety of front-line employees of the enterprise. Environmental awareness and technical level have improved qualitatively from the current primary stage. It is recommended to build chemical vocational colleges in key provinces in the dye and dye intermediate industry in the Yangtze River Economic Belt, to offer specialized courses and related majors, and to strengthen the training of professional talents.
The eighth is to resume export tax rebates for dyes and dye intermediates to enhance competitiveness in the international market.
In order to enhance the international competitiveness of my country’s dye industry, enhance the potential for enterprise development, reverse the passive situation of international competition, and guard against the “hollowing out” of the industry in my country’s construction of a world dye power, The industry hopes to resume the export tax rebate policy for dyes and intermediates, and recommends that relevant national departments provide full export tax rebate rates for dyes and intermediates products. In view of the fact that the technical level of dye intermediates such as resorcin and o-phenylenediamine in my country is comparable to the world’s first-class, such as Zhejiang Hongsheng Company’s technology for preparing resorcin by hydrolysis of m-phenylenediamine, which is currently the most advanced in the industrial production of resorcin. Competitive process routes, product quality is superior to foreign levels. In response to various factors such as the 25% punitive tariff imposed by the United States on my country’s resorcinol and o-phenylenediamine, the competitive pressure on domestic enterprises has increased unprecedentedly. In order to stabilize their international market position, domestic enterprises are encouraged to better expand the international market. , grasping the international voice of the dye and intermediate industry, proposes to increase the export tax rebate rate for resorcinol and o-phenylenediamine from the current 10% to 13%. At the same time, the export tax rebate policy for dyes and intermediates will be restored to promote the green and high-quality development of the dyes and intermediates industry.
