Make by-products a source of corporate profits

Business News Agency February 15th Shaanxi Shaanxi Coke Chemical Co., Ltd. is a joint-stock diversified company established in November 2002 based on the original coking plant in Shaanxi Province. It mainly produces metallurgical coke. After joining Shaanxi Coal Industry Group in June 2006, we took advantage of the strong financial strength and coal resources of Shaanxi Coal Chemical Group to form 2 million tons/year of coke and 200,000 tons/year of coke oven gas to methanol in the fourth quarter of 2010. Such production capacity has become the largest coking enterprise in the west, and the scale efficiency and risk resistance capacity of the enterprise have been significantly enhanced.

However, we also encountered many difficulties. On the one hand, the price of coke products is difficult to increase due to the country's tightening of real estate control, the insufficiency of steel companies' operating capacity, and overcapacity in the coke industry. On the other hand, as the country reorganizes coal resources, the international crude oil price continues to rise and drives coal and other resources. The price of products has risen and the cost of enterprises has risen sharply. If you do not take effective measures, losses are inevitable.

To cope with the unfavorable situation, this year's Shaanxi Coke Company relies on its blended coal technology for many years to deploy coking coal, fat coal and lean coal scientifically, and adjust and optimize coking process parameters to produce high-quality coke, significantly reduce costs and ensure coke Plates do not sustain losses.

At the same time, we must intensify the commissioning of a 200,000-ton/year coke oven gas methanol plant and strive to produce products in March and April. Because the methanol produced by coke oven gas is a resource utilization of exhaust gas, the cost of methanol is at least RMB 1,000/ton lower than the cost of pure methanol. Once the methanol plant is produced normally, even if it only produces 100,000 tons of methanol for the whole year, it will bring at least 150 million yuan in profits to the company.

Not only that, because of the large amount of carbon monoxide and carbon dioxide consumed in the production of methanol, the hydrogen content in the methanol plant pool is as high as 95%, which is a great pity for both venting and burning. After repeated demonstrations, we decided to use this portion of hydrogen and the existing 13,000 m3/hour air separation plant to build a 70,000 tons/year ammonia plant. The feasibility report of this project has been approved by Shaan Coalification Group and the preparatory work for the project is currently underway. After it is put into operation, it can bring 140 million yuan of profits to the company each year.

In addition to the existing tar, benzene, ammonium sulfate and other chemical products, these by-products will bring about 300 million yuan in profits this year. The company will form a pattern in which the main products of coke don't sustain loss and profit from chemical by-products. Under the premise of improving the market for coke, the company's annual profit can reach more than 400 million yuan.
