1.总论
1.1主要设计依据
编制本项可行性研究依据的主要文件如下:
(1)《辽宁省本溪市企业投资项目备案确认书》
(2)《本溪北营钢铁(集团)建设10万m3焦炉煤气柜项目建议书》
(3)本溪北营钢铁(集团)有限公司与中冶京诚工程技术有限公司签订的《本溪北营钢铁(集团)有限公司建设100000m3干式焦炉煤气柜工程设计合同》1.2本溪北营钢铁(集团)有限公司概况
1.2.1企业概况
北营公司位于辽宁省本溪市平山区北台工业园区,为北钢集团的核心单位,地理位置和交通条件十分优越。
现拥有资产总额182亿元,员工2.7万人,2005年销售收入总额113亿元,同口径实现税金5.75亿元,直接利用外资额3200万美元。
北营公司的主要设备有:
300m2、360m2烧结机各一台,4座420m3高炉,9座530m3高炉,4座50吨氧气顶吹转炉、3座120吨顶底复吹转炉,及与之相配套的CAS-OB炉、LF炉、VOD炉及RH炉等炉外精炼设施;4台方坯连铸机、4台板坯连铸机、1台方矩形坯连铸机;2条棒材生产线,4条线材生产线,1条热轧中宽带钢生产线;1条1780热轧生产线。
现已形成年产800万吨生铁、750万吨粗钢、900万吨钢材(根据市场调节品种)的综合生产能力。
北钢集团下属辽宁北方煤化工公司利用北营公司剩余的焦炉煤气、高炉煤气已建成年产61万吨尿素、3万吨甲醇项目。
1.2.2现有煤气产量、利用情况及建设焦炉煤气柜的必要性
1.2.2.1现有煤气产量、利用情况
北钢集团下属北营钢铁集团新区建有4×72孔4.3m焦炉四座,按设计指标生产时,小时产焦炉煤气89,400m3/h,焦炉自身加热使用高炉煤气,89400m3/h焦炉煤气除化产自用25000m3/h外全部外供。
焦炉煤气主要用户是煤化公司、1780热轧以及三铁、四烧等一些零星用户。
1.2.2.2新区建设干式焦炉煤气柜的必要性
北钢集团已形成年产800万吨生铁、750万吨粗钢、900万吨钢材的综合生产能力,轧材能力大于粗钢能力,可以根据市场需要调节产品品种。
为炼铁需要有焦炉8座,年产焦炭能力297.4万吨。
全厂生产分三个区,老区东部有高炉四座、焦炉二座;老区西部有高炉三座、焦炉二座;新区有高炉6座,焦炉4座。
各区边界有山河相隔,中心距离约1.5公里,区域之间有铁路管网相连。
为充分利用煤气杜绝放散,稳定管网压力,除炼钢设有回收转炉煤气的气柜以外,老区东部已建有10万m3干式焦炉煤气柜一座,2万m3干式焦炉煤气柜一座,老区西部已建有10万m3干式焦炉煤气柜一座,5万m3干式焦炉煤气柜一座,新区已建有16.5万m3干式焦炉煤气柜一座,但尚未建焦炉煤气柜。
为发展循环经济,尽可能的利用低热值的高炉煤气,发电厂烧单一高炉煤气,利用蓄热式技术,高线、中宽带烧单一高炉煤气,利用复热式技术焦炉用高炉煤气加热,置换出尽可能多的珍贵的焦炉煤气用于化肥生产尿素、甲醇,使之从燃料提升为化工原料。
