焦化行业 如何转型升级

2017-08-28 07:26:50   中国青年网

山西永鑫焦化有限责任公司始建于2003年,是集炼焦、化产回收、焦炉煤气制甲醇等为一体的循环经济民营企业,是我省循环经济试点企业,省级企业技术中心。近年来该公司的三条生产线基本保持了正常运行,但在环保方面遇到了压力:已建成的环保设施在连续运行过程中间断性出现一些问题,特别是运行成本要远高于项目调研和立项期间的预算,从运行管控上还需持续优化;公司正在实施的一些环保项目,技术的论证还不是很清晰。

环保压力是我省焦化行业普遍面临的问题,技术装备水平、产能利用率、融资等也成为制约焦化行业长期向好的因素。焦化行业是能源资源消耗和污染物排放重点产业之一,去年以来,我省环保部门通报处罚的超标排污企业中,焦化企业占到较大比重,处罚金额重,社会营销大。随着国家对环境治理监管力度不断加大,节能减排已成为影响我省焦化行业产量和效益增长的主要原因之一。

其次是技术装备水平偏低。当前我省焦化企业总体设备仍以普通4.3米焦炉为主,与5.5米以上大机焦炉设备相比,同产量下4.3米焦炉开关炉门次数多,排污量相对较高;且不能配套炭化室多段加热等先进技术,生产效率相对较低。第三是产能利用率不高。2016年全国焦炭产量4.48亿吨,产能利用率66.1%;我省建成焦化产能约1.4亿吨,产量8189万吨,产能利用率56.4%,低于全国9.7个百分点。

此外,融资问题相对突出。2016年以来焦化全行业增速,产量、价格、效益全面回升,企业发展信心大幅增强,实施技术改造的意愿强烈。但由于多年亏损,企业资产负债率普遍较高,金融机构对煤焦钢行业自2015年以来一直采取抽贷和严控新贷政策,融资渠道受阻。

节能减排、转型升级、提质增效才是出路

7月下旬,一套总投资达1.5亿元、综合了焦炉烟气脱硫脱硝和余热回收工艺的环保装置在山西焦化集团有限公司成功完成单机试车,这不仅标志着该企业烟气脱硫脱硝技术达到国内先进水平,也为焦化行业废气深度治理提供了一个成功样本。近年来,我省最大的独立焦化企业山西焦化坚定不移地走绿色发展、循环发展、低碳发展道路,像这样瞄准行业领先水平并不惜重金“砸”向环保项目的大手笔已成新常态。

我省焦化行业的总体发展思路是:坚持“稳焦兴化、焦化并举、上下联产、以化领焦”,围绕“节能减排、转型升级、提质增效”,下一步要加快环保提标改造,加大节能投入,提升全行业低碳绿色发展水平;稳步推进现代化大型焦化项目建设,不断提高焦炉技术装备水平;着力延伸焦化化产品深加工产业链,培育壮大化产品深加工产业;严格控制焦炭总产能,优化调整产品结构,引导部分企业向化工焦和洁净焦转型,积极探索化解产能过剩新途径。
