编制本项可行性研究依据的主要文件如下：

（1）《辽宁省某市企业投资项目备案确认书》

（2）《某北营钢铁（集团）建设10万m3焦炉煤气柜项目建议书》

（3）某北营钢铁（集团）有限公司与中冶京诚工程技术有限公司签订的《某北营钢铁（集团）有限公司建设100000m3干式焦炉煤气柜工程设计合同》1.2某北营钢铁（集团）有限公司概况

1.2.1企业概况

北营公司位于辽宁省某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。
