On November 2, China's first million-ton large-scale blue-carbon production enterprise, Shaanxi Coal Chemical Group Shenmu Energy Development Co., Ltd. was established. Its establishment has opened a prelude to the consolidation of Shaanxi's blue-carbon enterprises, marking the former charcoal industry known as “high energy consumption, high pollution, smallness, chaos, and bad” and stepping into the grouping, intensification, and resource integration. The use of circular economy development track.

The company is located in the Ningtu tower carrier energy industrial concentration area in Shenmu County, Yulin City. It is a joint venture formed by five companies, namely Shanxi Coal Chemical Group Shenmu Coal Chemical Industry Co., Ltd. and Shenmu Lianzhong Coal Chemical Industry Co., Ltd. The new company will invest 2 billion yuan to build 2.6 million tons/year of blue carbon, 300,000 tons/year of calcium carbide, 4 x 50 megawatts (one period of 2 x 50 megawatts) of coke oven gas power generation and coal tar hydrogenation and other large coal char Electrochemical integration project.

According to the plan, about 1.5 billion cubic meters per year of coke oven gas produced from 2.6 million tons/year of blue charcoal will be used for power generation, except that a small part is used for the drying and heating of raw coal and baking of white ash; white ash, blue carbon, and electricity As a calcium carbide raw material, 300,000 tons/year of calcium carbide is produced; calcium carbide products are supplied to the nearby Shenmu Beiyuan Chemical Co., Ltd.; polyvinyl chloride is produced; coal tar directly produced by the production of blue carbon is directly supplied by Shenmu Tianyuan Chemical Co., Ltd. and Shenmu Rich Oil Energy. Technology Co., Ltd., and the use of medium-temperature coal tar hydrogenation technology, the production of high value-added gasoline, diesel and other chemical products. This formed a complete and closed circular economy chain, which saved resources, protected the environment, and reduced costs.

Blue carbon is the main raw material for the production of calcium carbide, synthetic ammonia, and ferroalloys. In 2007, China had nearly 300 companies producing blue carbon, with a production capacity of about 23 million tons, and 70% of them were concentrated in the Yulin area of ​​Shaanxi. Due to the small scale, dispersive layout, and backward technology, about half of the enterprises' coke oven gas and coal tar are not recycled, resulting in greater waste of resources and environmental pollution. In order to change this situation, since 2007, Shaanxi Province has closed nearly 200 companies of the company, and eliminated more than 10 million tons of backward production capacity per year. In 2008, in line with the principles of grouping, intensive, and favorable for the recovery and utilization of coal tar and coke oven gas, Shaanxi Province re-planned 30 production capacities of 600,000 tons/year or more, process technology, furnace height, environmental protection facilities, and energy consumption. The blue carbon companies whose indicators meet the entry requirements have promoted large enterprises to integrate local resources through mergers and reorganizations. Shaanxi Coal Chemical Group Shenmu Energy Development Co., Ltd. has emerged as the times require.
