After the baptism of the financial crisis and changes in the structure of market demand, the company was acutely aware that the traditional coking product structure could not meet the market demand for “drilling†and must extend to the fine chemical industry such as deep processing of tar and deep processing of crude benzene. This establishes two main lines.
One of the main lines is to make products thin. Domestic coking companies generally adopt the traditional acid-washing method to make benzene. After the company built a 100,000-ton-class benzene hydrogenation unit, it replaced the previous refined benzene plant that used benzene to produce benzene. The new device uses crude benzene as raw material to produce pure benzene, toluene and xylene. It is currently one of the most advanced crude benzene refining technologies in the world. It can reduce COD emissions by 22.5 tons per year and reduce annual wastewater discharge by 1.67 million tons.
While improving the environmental benefits, the economic benefits of the company have also greatly increased. By "incubating" in a benzene hydrogenation unit, the purity of the above three benzenes can reach 99.9%, and the yield can be increased by 2%. It can also meet the needs of high-end customers such as styrene and TDI (toluene diisocyanate) production companies. According to conservative calculations, it can generate more than 100 million yuan each year.
In the past few years, the 7.63-meter and 7-meter large-scale coke ovens of the Coking & Chemical Co., Ltd. of Pingmei Coal have been completed and put into operation. With the enlargement of the coke oven, the output of crude tar produced during the coke smelting process is also increasing day by day, and the annual output reaches 340,000 tons. The processing capacity of the existing coal tar processing system is far from meeting the needs of production, and a large amount of crude tar is incapable of being processed and forced to be exported directly. After scientific demonstration, the company started a tar deep-processing project. The first-phase construction scale is 500,000 tons. Through advanced international technology, deep tar processing will be carried out to produce a variety of fine chemical products. The annual sales income after the project is put into production can reach 1.4 billion yuan.
The second line is to make the product fine. The company holds a production and sales balance meeting every month, adjusts the structure of some products in time according to market conditions, and produces more fine chemical products with high added value and good sales. Due to technical reasons, many domestic coal tar processing companies no longer process common medium-temperature bitumen, and their prices are often lower than raw materials (tar), affecting corporate profits. Pingdingshan Iron and Steel Co-Coke Co., Ltd. improved the asphalt production process to improve the quality of the modified asphalt, resulting in a "higher price" and also avoiding the disadvantages of medium-temperature asphalt that is not easy to store in summer (softening point is low). Nowadays, the price per ton of modified asphalt produced by the company is higher than that of medium-temperature asphalt by 100 yuan, and it can earn 2.5 million yuan more in one year.
Previously, the company's degummed oyster oil was mainly used to produce fuel oil. After full market research this year, they used most of the degreasing oil to produce carbon black oil with a relatively high added value. Although the production of fuel oil and production of carbon black oil are similar, the production cost per ton of carbon black is about 50 yuan more than the production cost per ton of fuel oil, but the market price of carbon black oil is higher than 200 yuan per ton of fuel oil. . Deduction cost factors, more than 150 yuan per ton of carbon black oil than fuel oil.
According to the plan, the company will build two sets of 500,000 tons of tar deep-processing projects and two sets of 100,000 tons of benzene hydrogenation equipment in the future, and its fine chemical industry will develop rapidly in the 21st century.
In the past two days, at the construction site of the 500,000 tons/year tar deep-processing project of Pingdingshan No. 5 Co., Ltd., the reporter saw the construction vehicles shuttle and the construction of surrounding roads proceeded intensely. The scenes were intense and busy. This is a microcosm of the development of tar deep processing in Pingdingshan Iron and Steel Coking Co., Ltd., and actively exploring the development of fine chemicals.
