近日，四川启明星铝业有限责任公司传来重大进展：其电解铝节能及环保绩效升级改造项目 168 台电解槽全部完成通电调试，并实现满负荷稳定运行。作为四川省 2024 年重点推进的绿色制造项目，这一突破标志着企业在降本增效、低碳转型的道路上迈出关键一步，为西南地区铝工业高质量发展树立新标杆。

技术革新驱动产业升级
该项目自 2024 年 3 月启动以来，以 “能效对标国家标杆、环保争创行业 A 级” 为目标，对现有电解槽及配套设施进行系统性改造。通过联合贵阳铝镁设计院研发的平衡铝流电解槽技术、高导母线节能技术等 16 项行业前沿成果，企业实现铝液综合交流电耗在设备启动期降低 600 度以上。改造后，年节电能力达 7100 万度，相当于减少标煤消耗 2.5 万吨，CO₂排放量同比削减 3.95 万吨，颗粒物、二氧化硫等污染物年减排量超 900 吨，直接降本增效 3600 万元。

全流程绿色化改造
项目总投资近 8 亿元，重点围绕电解车间、焙烧车间等核心环节展开升级。通过优化电解槽结构、革新烟气治理工艺，企业构建起 “上位双烟道负压收集 + 三级脱硫脱硝” 的全流程污染防控体系。其中，焙烧烟气处理系统新增沸石吸附与催化燃烧装置，脱硫效率提升至 98% 以上，氮氧化物排放浓度低于 50 毫克 / 立方米，各项指标均优于环保绩效 A 级企业标准。

产能置换释放新动能
项目严格遵循国家产能置换政策，通过淘汰同规模老旧产能，实现 “等量替换、质效提升”。改造后，企业电解铝年产能维持 12.5 万吨不变，但产品结构向高端铝液、圆铝杆等深加工方向延伸，配套建设的雨污分流系统及智能化仓储物流体系，进一步强化了与下游新能源、高端制造产业的协同能力。

区域协同助力双碳目标
作为眉山市 “千亿级铝基新材料产业集群” 的重要组成部分，启明星铝业的技术突破为区域产业升级注入新动能。项目建成后，企业能效水平跃升至《电解铝单位产品能源消耗限额》标杆行列，预计每年可减少标煤消耗 3.9 万吨，相当于种植 200 万棵云杉的碳汇能力。未来，企业将持续深化与西安交大等科研机构的合作，探索铝灰资源化利用、绿电直供等创新模式，为成渝双城经济圈绿色发展提供产业示范。
