The Green Development Road of Shanxi Yongxin Coal Coking Co., Ltd.

With the deepening of spring, full of green is everywhere in Jinnan.

Shanxi Yongxin Coal Coking Co., Ltd. (hereinafter referred to as "Yongxin Coking"), deep in the Taiyue Mountains and surrounded by tall pines, is more fresh and refreshing against the blue sky and white clouds.

Being in the factory, you can't see the smoke flying and smell the pungent smell, which completely subverts and reshapes the mindset and inertia cognition of traditional coal coking enterprises in your mind. This is the most intuitive visual image of this "green factory".

Walking into one workshop after another, advanced environmental protection facilities and equipment run in parallel and efficiently, which is the best annotation to the green development of Yongxin Coking Company.

Guided by green development

Why did Yongxin Coking shake off "a piece of dust"? The answer is not difficult to find.

Walking into the intelligent explosion-proof control room of the factory, a group of employees are monitoring the operation in front of the computer. The screen wall shows that the inspection robot shuttles back and forth in the coke oven basement, and the detection data is transmitted to the control room synchronously. Everything about the "safety index" of coke oven production is under control.

Yongxin people are proud of the intelligent platform of unorganized emission control integration, which really deserves its reputation. Here, 23 sets of high-efficiency fog guns are installed in the fully enclosed coal char storage greenhouse, and the fog guns adopt three-stage linkage to automatically control the dust escape, and 24 sets of high-efficiency dry fog curtains installed at the entrance and exit of the greenhouse adopt infrared induction to automatically control the dust escape; 28 dust detection devices have been installed in the factory. Detection facilities and sweepers transmit dust alarm signals through GPS, which can directly command sweepers to control dust in the factory.

It is worth mentioning that the air quality data of the factory area is also connected with the data of various air quality monitoring points in Linfen City in real time. The data comparison shows that the air quality index of the factory area is better than the average level of the whole city.

These are just the tip of the iceberg of this "green factory".

As the core unit of industrial manufacturing process, green factory is the core object of practicing green development concept and realizing green transformation and upgrading, and it is also an important starting point for green transformation. As a private enterprise with circular economy integrating coking, chemical product recovery, methanol production from coke oven gas and ammonia production from methanol purge gas, Yongxin Coking has always adhered to the green development concept of "making unremitting efforts to become a resource-saving and environment-friendly modern coal chemical enterprise" for many years. Niu, the general manager of the company, said that since the Ministry of Industry and Information Technology organized the recommendation of green manufacturing list on 20 17, the company has actively promoted the implementation of various environmental protection and energy-saving projects, set up a green factory management team, and improved and improved the level of green manufacturing one by one according to the General Rules for Green Factory Evaluation and the requirements for green factory evaluation. "In recent years, a total of 670 million yuan has been invested in environmental protection and energy conservation, and more than 30 technical transformation and construction of environmental protection facilities have been implemented with high standards."

On June 29th, 2020 10, Yongxin Coking Company was successfully selected as a national-level green factory, becoming the only independent coking enterprise in the province that won this honor. "This is a recognition and affirmation of our unswerving and unremitting efforts in safety, environmental protection, energy saving and quality for many years." Niu Ruping said.

Supported by technological innovation

The traditional coking industry is characterized by high energy consumption, high emission and high pollution, which has great potential for energy saving and carbon reduction.

For Yongxin Coking Company, the application of new technologies and new processes is endless-

Through CDQ and CDQ power generation projects, the energy consumption level of the factory was suddenly reduced. The data show that in 20 16 and 20 19 years, the company completed and put into operation10.2 million tons/year dry quenching waste heat power generation and 600,000 tons/year dry quenching devices respectively, saving 86,000 tons of standard coal every year.

The implementation of the technical transformation of "zero discharge" of factory wastewater has also achieved remarkable results. As the first high-concentration brine treatment plant with complete process chain in China, the zero-emission coking wastewater project can save 439,200 tons of water every year, and the zero-emission chemical brine plant can save 558,400 tons of water every year.

Through the technical transformation of sulfuric acid production from coking desulfurization waste liquid, the operation parameters and stability of the whole plant are in the forefront of similar devices in China. The recycling of sulfur resources is realized through the acid production project from waste liquid, which fundamentally solves the waste of sulfur resources in the traditional desulfurization process and the secondary environmental pollution of desulfurization by-product waste liquid. The produced sulfuric acid can be used as raw material for deamination of coke oven gas to produce ammonium sulfate, which can effectively recover sulfur resources.

The intelligent safety inspection project of 5G robot is developed with advanced 5G communication technology, which realizes uninterrupted intelligent inspection of coke oven bottom and real-time detection and alarm of toxic and harmful gases, greatly reducing the time of personnel in dangerous areas. 65438+ 10 In June, 2022, this technology has obtained the patent of utility model in China National Intellectual Property Administration.

…………

The comparison of groups of data objectively reveals the benefits brought by technological innovation to Yongxin Coking Company in terms of safety, environmental protection, energy saving and quality.

Driving industrial green development with scientific and technological innovation is the key to promoting high-quality economic development. Over the years, Yongxin Coking Company has carried out the green transformation of extensive production mode from the source, and successively implemented 6.5438+0.2 million tons/year CDQ waste heat power generation, coke oven flue gas white smoke desulfurization and denitrification high emission and ultra-low emission transformation, coke oven unorganized smoke control transformation, VOCs control, 600,000 tons/year CDQ, desulfurization waste liquid acid production, zero discharge of high-salt inorganic wastewater, zero discharge of coke oven wastewater and six-parameter air micro-monitoring. Advanced, practical and effective projects such as the integrated intelligent platform for dust and VOCs unorganized emission management, control and treatment, and LDAR technology have realized a truly odorless, clean and bright factory area and enhanced the market competitiveness of enterprises.

Take circular development as the core

Comprehensive utilization of resources is regarded as an effective means to promote the fundamental transformation of resource utilization mode, vigorously save and intensively use energy resources and develop circular economy, and is a solid guarantee to implement the requirements of industrial green development.

As a pilot enterprise of circular economy in Shanxi Province, Yongxin Coking has long been committed to building an integrated green and low-carbon circular coal chemical enterprise. Over the years, we have continuously invested funds, constantly improved the industrial chain, and strived to achieve "eat dry and squeeze clean" and "zero discharge" of solid waste and wastewater, and built a complete industrial chain with close connection between upstream and downstream.

In the upstream, in order to facilitate clean coal transportation and reduce the impact of transportation on the environment, the company invested in the construction of Yongxin railway special line; The downstream extends the industrial chain with power generation, methanol and synthetic ammonia, forming a complete industrial chain of "coal mining-coking-power generation-methanol-synthetic ammonia". Through the construction of circular economy, zero discharge of wastewater, full recycling of solid waste and ultra-low emission of flue gas will be realized.

In order to further promote the development of the whole coking industry chain, Yongxin Coking also vigorously develops the carbon-based new material industry. At present, a series of products, such as microcrystalline coke, carbazole, anthraquinone and permanent solid, are being developed downstream of coal tar, which will create a new pattern of circular economy industry of coal coke and chemical industry.

Traditional advantageous industries are the "ballast stones" to stabilize Linfen's economic operation. At the beginning of this year, the Economic Work Conference of the Municipal Party Committee pointed out that industries should strive for progress steadily, improve quality and increase efficiency, and traditional advantageous industries should strengthen chains and forge long boards, aiming at "double lines" and high-end low-carbon development.

As one of the transformation benchmarks of coking enterprises, Yongxin Coking is a veritable "chain owner" enterprise with its strong strength and leading position in the industrial chain. Giving full play to its leading and supporting role will help the upstream and downstream enterprises in the industrial cluster to benefit widely, thus driving the regional economic development.

Green is the background color of high-quality industrial development. Yongxin coking is a bright green color for Linfen to build a high-quality modern industrial system. (Sun,)
