榆林推动煤化工产业迈向高端
2017-08-11 11:26:42 中国青年网
神东、陕北2个亿吨级煤炭清洁高效利用示范基地、世界最大的镁产业基地、国内最大的兰炭生产基地、国内最大的甲醇生产基地、国内大型火电基地、国内煤制烯烃第一大市,一个个耀眼的“名片”是榆林转型发展中收获的累累硕果。一个个行业领先、国内第一、世界首个,榆林全面转型升级的“骨架”已搭起,抢占发展先机的“发动机”已轰然而鸣。
榆林煤化转型高端化
榆林将煤化产业向纵深、精细、高端的不断推进,也是多年来地方政府坚持从产业布局理念到制度机制,再到管理服务创新的结果。
“榆林版煤制油”值得大书特书。陕北煤炭资源整合后,原来落后产能采掘工艺所生产的块煤被粉煤所代替,新采掘工艺下煤矿煤炭产量的70%形成了粉煤。原本以块煤为原料的炼焦产业,使得块煤市场价格高昂,而粉煤市场价格一路低迷。打通粉煤炼焦工艺,是民营企业家多年的梦想。国家级开发区榆神工业区引进孵化的陕西富油能源化工企业攻克了我国粉煤炼焦提取煤焦油的难关,该项目得到了我国第四大能源巨头陕西煤业集团的鼎力支持。目前陕煤已经启动了“富油”的扩大升级版。一旦大规模的商业化得以推广,榆林地方煤炭粉煤产能的相对过剩问题将得到彻底解决。而从煤到焦油、再到榆林版煤制油的全新产业链条,形成良性大规模转化的商业路径,其商业价值无法估量。目前,已有神木富油与大连理工大学合作将粉煤炼焦提油成功;浙江大学流化床煤干馏与锅炉结合,煤气生产甲醇,回收煤焦油,兰炭作为锅炉燃料发电,已取得中试成功;被称为“榆林版”煤制油的陕西天元化工已经获得巨大经济效益。相关资料显示,陕西地方能源巨头延长、陕煤与地方民营企业参股合作的煤炼焦项目,几年前早已展开,近两年的趋势是煤焦油制汽柴油。延长石油在靖边以煤油气为原料的综合实验探索已经取得成功,目前正利用新技术在榆神开发区上马新的煤制油化工项目。目前,榆林已具备卖煤先取油的大规模工业产业推广条件,正在引导大面积推广。
榆林市能源局统计的数据显示,2016年榆林煤炭产量共计3.61亿吨,电力就地转化的煤3000万吨,“十三五”时期达到6000万吨。在未来五年,榆林市的主要目标之一便是加快兰炭产业转型升级,煤炭转化率达到50%,中高端煤化工产品产能突破3000万吨,建成国家级煤炭清洁高效利用示范区。
陕西的煤化在陕北,陕北的煤化在榆林。历经多年以科技为核心的创新转型,榆林正在向千亿吨级国家大型煤炭基地、三千万千瓦国家大型煤电基地、千亿吨级高端煤化工基地、百亿吨级新型材料基地、千万千瓦级新能源基地迈进。
