为了企业发展钻研技术改造

——记2017年沈阳五一劳动奖章获得者、沈阳化工集团石蜡化工有限公司乙烯分厂孙章

14年来,他对企业真诚奉献、不计名利;对工作脚踏实地、真抓实干,不断攻克生产难关。他刻苦钻研,大胆实践,积极开展技术改造;他团结同事共同前进、富有爱心,深受领导和同事的尊重……他就是2017年获得了沈阳五一劳动奖章的沈阳化工集团石蜡化工有限公司乙烯分厂厂长助理孙章。

勤奋学习,攻坚克难

孙章2003年参加工作,作为生产一线的岗位工人,他虚心学习,努力做好本职工作,在很短的时间内就学会了整个装置的工艺流程及岗位操作法,很快由一名泵工成为主要岗位的主操,他所在的班组当年在分厂生产竞赛中夺得第一名。

2010年1月,分厂进行停工检修。因急冷器抽出结焦影响生产,他带领工人不畏严寒,在70米高的急冷器内奋战一天一夜没合眼,终于将结焦部位清理干净,并将管线合口、设备封闭,保证了装置检修如期开车。事后,他与分厂和技术部门人员分析急冷器结焦的原因,提出了工艺流程改造,调整生产操作指标,下达了严格的工艺操作规程,严格控制生产操作参数,延缓了急冷器的结焦时间。

胆大心细,大胆实践

一次,他在检查DCS画面时,发现两个缓冲罐的液位之和下降了约0.1%,十分异常。他立即组织岗位人员到现场检查,发现油气急冷器抽出阀门发生内漏,导致在塔外循环的油品窜入塔内,如不及时处理,整个装置将会被迫停工。他当机立断,根据生产运行情况,调整分馏系统的操作流程,切换下来该阀门去检修,保证了装置稳定生产未受影响。

2012年11月末,他在现场检查生产运行时,看到油浆泵电流持续超高,经过化验分析油浆密度及固含量都不超标。油浆泵是保证生产稳定的关键设备,电流持续超高会严重影响生产安全。他带领岗位工人到生产现场反复检查设备,发现有一个控制阀的声音不正常,经拆开检查发现是阀板丢失导致电流过大。他提出将控制阀拆下换为限流孔板后,油浆泵电流恢复正常,保证了装置的运行安全。

刻苦钻研,孜孜以求

2013年9月开始,急冷器出入口的压差持续上升,严重影响装置的安全运行,如果更换催化剂需要一大笔费用。如何攻克这个难关,是决定生产装置稳定运行的关键。孙章利用周末时间到省市图书馆查阅资料,又主动放弃休息时间与助剂厂家交流,选择合适的助剂来缓解结焦问题,还编制了特种助剂注入施工方案,并设计了注入点及注入量,有效缓解了急冷器压差升高的问题。

多年来,孙章完成了10余项技术改造项目,为装置长周期稳定运行作出了贡献。他还提出了诸多合理化建议,为企业节省了资金,创造了效益。2013年,他响应公司提出的节能降耗号召,提出了“利用CPP余热水作为装置冬季采暖”的合理化建议,当年冬季仅CPP装置就节约采暖费用45万元。2014年,他提出了“减少罐区输入流转、增加原料直供装置”的持续改进建议,并做出了工艺调整方案,项目实施后,每年可为企业降低加工成本260万元。
