随着先进工艺技术的不断运用,特别是循环经济理念的融入渗透,榆林市兰炭产业已经从过去单纯以兰炭生产为主逐步向拓展下游产业链方向发展,既生产兰炭,又利用焦油加氢制取清洁燃料油、焦炉煤气制取甲醇或做燃料,实现了一举三得。“京府”:开展资源循环综合利用2008年,京府煤化工集团公司积极响应政府号召,关停整合了18家小兰炭企业,投资13亿元自主建设新尧兰炭集中区。以兰炭生产为上游龙头,配套建设金属镁厂、兰炭尾气发电厂、硅铁厂、电石厂、洗煤厂、石灰厂和免烧砖厂等8个子项目。形成了上下游相对接、多种产品相支撑;资源循环综合利用、产业链条延续完善;清洁环保、节能减排的循环经济链条。年设计生产能力兰炭96万吨、焦油10万吨、金属镁2万吨、发电3.5亿度,电石30万吨,硅铁10万吨,石灰
With the continuous use of advanced technology, especially the integration of circular economy into the infiltration, Yulin City, blue carbon industry has been purely from the past blue carbon production gradually expand the direction of the downstream industry chain development, both producing blue charcoal, but also the use of tar Hydrogenation to make clean fuel oil, coke oven gas made of methanol or fuel, achieved three goals. “Beijing government ”: comprehensive utilization of recycling resources In 2008, Beijing Coal Chemical Industry Group actively respond to the call of the government, shutting down the integration of 18 small blue charcoal enterprises, 1.3 billion yuan investment to build new Yao Lan carbon concentration area. To blue carbon production as the leading bureaus, supporting the construction of magnesium metal plant, Lancang tail gas power plant, ferrosilicon plant, calcium carbide plant, coal washing plant, lime plant and unburned brick factory eight sub-projects. Formed a relative upstream and downstream, a variety of products phase support; comprehensive utilization of resources recycling, industrial chain continued perfect; clean and environmental protection, energy saving and emission reduction chain of circular economy. Annual production capacity of 4,700 tons blue charcoal, tar 100,000 tons, 20,000 tons of magnesium, generating 350 million degrees, 300,000 tons of calcium carbide, 100,000 tons of ferrosilicon, lime
