年度回顾 | 水泥行业积极应对“减碳”大考

2023-12-29 15:02:54

水泥行业应认清形势变化,捕捉低碳大势带来的商业模式变革机会。

由于产业规模大、窑炉工艺特点等原因,水泥行业是工业能源消耗和碳排放的重点领域,是我国碳减排任务最重的行业之一。

资料显示,水泥行业的碳排放量约占全国碳排放总量的13%,因此,水泥行业实现碳达峰对工业,乃至全社会如期实现碳达峰目标至关重要。

观察今年水泥行业发展,碳减排无疑是一个重要的关键词。在高库存、高成本、产能严重过剩的当下,水泥企业越来越清楚地意识到,低碳、绿色是未来发展的核心要素。

政策方向明确 水泥行业低碳发展势不可挡  

2月,工业和信息化部发布的《工业节能监察办法》正式施行,理顺工业节能监察职责分工,健全工业节能监察体系,为各级工业节能监察部门开展工作提供制度保障。2月16日,最高人民法院发布《最高人民法院关于完整准确全面贯彻新发展理念为积极稳妥推进碳达峰碳中和提供司法服务的意见》,以及11件司法积极稳妥推进碳达峰碳中和的典型案例,进一步总结审判经验,指导各级人民法院正确审理各类涉碳纠纷案件。  

4月,国家标准化管理委员会、发改委、工信部等十一部门联合印发《碳达峰碳中和标准体系建设指南》,提出将围绕基础通用标准,以及碳减排、碳清除、碳市场等发展需求,基本建成碳达峰碳中和标准体系。

7月,中央全面深化改革委员会第二次会议审议通过了《关于推动能耗双控逐步转向碳排放双控的意见》,提出要立足我国生态文明建设已进入以降碳为重点战略方向的关键时期,完善能源消耗总量和强度调控,逐步转向碳排放总量和强度双控制度。能耗双控逐步转向碳排放双控调整,标示着系统化、体系化地全面推动建材行业绿色低碳转型发展的宏观环境已经建立。

10月,生态环境部发布《关于做好2023—2025年部分重点行业企业温室气体排放报告与核查工作的通知》,其中详细介绍了水泥熟料生产碳排放量计算公式。

11月,国家发展改革委印发《国家碳达峰试点建设方案》。11月24日,国家发展改革委等部门联合发布了关于加快建立产品碳足迹管理体系的意见,水泥行业的碳排放核算由此将“有迹可循”。

探索减碳路径 打好转型升级组合拳

如何才能有效的大幅削减单位水泥的二氧化碳排放量,既不影响水泥的使用性能和运作方便,还能保持比较低廉的水泥生产成本?水泥行业展开了对碳减排路径的路径的探索。

替代燃料

有数据显示,如果在水泥生产中使用40%的替代燃料,每生产100万吨熟料将少排放约10万吨二氧化碳。近年来,海螺水泥、天山股份、华新水泥、塔牌集团等不少水泥企业都在加快推进非化石能源替代燃料,推行能源结构绿色化。  

3月,洛阳中联就地取材开始从当地香菇基地回收废菌棒和废树枝,通过破碎机破碎,皮带运输到热盘炉,在热盘炉内燃烧;燃烧后热量通过分解炉进入旋风筒内进行热交换,从而达到生物质燃料替代化石燃料的目的。  

生物质燃料使用后有效地减少原煤的使用,从而达到节能降碳的效果,不仅可节约成本,而且低碳环保。根据目前使用情况分析每小时使用3吨的生物质燃料,可降低1吨原煤,从而减少2.25吨CO2排放,仅当地生物质燃料每年就可减排2370吨CO2。  

CCUS

碳捕集利用与封存(CCUS)是指将二氧化碳从工业过程、能源利用或大气中分离,直接加以利用或注入地层,以实现二氧化碳永久减排,是我国实现碳达峰碳中和不可或缺的关键技术,在水泥行业应用十分广泛。

4月,豪瑞(Holcim)在发布2023年气候报告时承诺,将于2030年前投资20亿瑞士法郎(折合22亿美元)用于碳捕集技术,重点关注成熟技术,并承诺每年捕集超过500万吨二氧化碳。

6月,青州中联年产20万吨二氧化碳全氧燃烧富集提纯示范项目开工仪式顺利举行。

12月,海南省首个年捕集利用6万吨二氧化碳项目落户华润水泥(昌江)有限公司,该项目将使用碳捕集利用与封存技术,将捕碳、固碳、用碳产业化,实现二氧化碳资源化利用。

光伏发电

光伏发电作为一种绿色清洁能源,能够提供可再生的电力,有效缓解水泥企业面临的降碳压力。

2023年,水泥企业光伏项目迎新进展的新闻层出不穷。

冀东水泥赞皇公司2MW光伏发电项目成功并网、华润电力弥渡水泥厂举行分布式光伏项目开工、铜陵上峰二期4MW分布式光伏发电项目通过验收顺利并网、将乐金牛光伏发电停车场启用……

此外,还有台泥英德厂启用中国水泥行业最大储能系统;投资2900万元,塔牌集团新型储能项目开工;新疆天业联手国电投建设运营200MW光伏储能项目;葛洲坝水泥公司储能电站项目并网成功……

其他碳减排方式

除上述路径之外,今年国内水泥企业继续加大了节能技改、余热发电、原材料替代等方面的投入力度。

在节能技改方面,预热器5改6,2023年在水泥行业掀起了一波广泛的关注度。据东方希望重庆水泥生产技术负责人介绍,2022年9月份,东方希望重庆水泥3号线“5改6”项目完成,今年4月份2号线“5改6”项目也完成。改造完成后,东方希望重庆水泥吨熟料能耗指标下降明显,整体能耗水平位居行业前列。

“重庆东方希望水泥预热器‘5改6’项目的成功,可以说意味着‘5改6’项目已经能在水泥企业大范围推广。”西南科技大学副教授齐砚勇曾对中国水泥网表示。

在水泥行业,除近年建设的个别水泥企业以外,绝大多数5000t/d生产线都是5级预热器。齐砚勇表示5级预热器中,一级筒的废弃热量有不少水泥厂根本就用不完,经过余热发电后,废弃热量无法得到充分利用。但如果采用6级预热器,回收回窑的热量更多,剩余热量也刚好能满足生料工序的烘干,这对于节能减排有较大的意义。  

此外,余热发电技术虽然已经成为国内水泥企业的标配,但作为降低企业生产能耗的关键手段之一,2023年国内水泥企业仍在不断深入探索提高余热发电效率的方式,并取得了显著成效。

例如2023年8月,克州天山水泥公司举行余热发电建设项目开工启动仪式,项目选择10MW汽轮机+12MW发电机组+AQC锅炉+SP锅炉主机装备配置,建成后,电站可一键启停、智能运行,年发电量4408万千瓦时,年均降低碳排放3700吨。

在原材料替代方面,国内水泥企业开始更多的尝试用钢渣等工业固废部分替代石灰石,也为水泥行业进一步降低碳排放,提供了可行之策。

践行“双碳”目标 水泥企业如何走好转型路

2023年,水泥企业紧跟国家政策的引导,发挥科技创新的作用,持续在原燃料替代、碳捕集、光伏发电、储能、固危废处置、碳资产管理等方面不断实现突破,努力答好“双碳”的时代课题,助力水泥行业迈向绿色低碳循环发展。

11月,台泥宣布最高以新台币266亿元(折合人民币约60.5亿元)的金额,提高对土耳其OYAK水泥合资公司和葡萄牙Cimpor水泥合资公司的持股。这次台泥扩大持股,主要着眼于两家公司领先全球的低碳水泥研发与生产技术。台泥董事长张安平表示,未来不懂碳的公司无法生存,而低碳绝对是国际化市场。

水泥行业减碳潜力巨大,加快转型升级,迈入绿色低碳高质量发展阶段,有效实行节能减排和应对气候变化,可谓任重道远。

水泥行业应认清形势变化,捕捉低碳大势带来的商业模式变革机会,大力推动“低碳+数字化”的运营转型,探索可能的绿色增长新机遇,从更高层次、更系统化地推动形成现代化建材产业体系。

In view of the problems of declining profits of cement enterprises hindering green transformation and narrowing the space for energy saving and carbon reduction, Ye Jiayuan proposed that cement enterprises should not forget to innovate no matter how difficult it is. Innovation should not only be limited to low-carbon areas, but also open up ideas and plan digital upgrading and intelligent transformation as early as possible according to their own conditions. In the implementation of digital and intelligent transformation, it should be linked with low-carbon as far as possible. If digital intelligence leaves the foothold of low carbon, digital intelligence is likely to be hollow, and it is likely to become a castle in the air, which is not useful, but a burden for enterprises.
