1. 编制说明

依据大庆石化公司炼油厂一套常减压装置基础设计，减压塔、常压塔工程图。施工现场环境条件及我公司现有机械能力，特编制本方案。 2．工程概况

大庆石化公司炼油厂650万吨/年一套常减压装置安全节能改造工程，在炼油厂老区装置区内，占地24000m2。

该装置新增塔类设备5台，其中最大的塔类设备减压塔T-201安装后顶部标高76.85m，重 1135t，呈现了设备高、重、大的特点。该装置由大庆石化工程公司设计，大庆石化工程质量监督站质量监督，大庆石化工程有公司监理，大庆石化建设公司施工总承包，大庆石化机械厂主体设备制造施工。 3. 编制依据

3.1 大庆石化公司炼油厂一套常减压装置设备布置图 3.2 减压塔、常压塔基础设计工程图

3.3 石油化工建设工程施工安全技术规范GB50484-2008 3.4 大型设备吊装工程施工工艺标准SH/T3515-2003 3.5 利勃海尔，LR1400型400t履带吊技术性能表 3.6 250t履带吊技术性能表 4.设备吊装主要技术参数

序设备号 位号 1 2 名称 规格 材质 设备净重 （t） 1135 470.15 T-201 减压塔 T-102 常压塔 Φ9800/Φ6200×67094 S32168+Q345R Φ6800/Φ5800×70874 S11306+Q345R 5.吊装工艺及施工程序

减压塔、常压塔在工厂下料预置切割滚成弧形板，运入现场围板，立置组对焊接成型，减压塔分6大段吊装，常压塔分成4个吊装段进行安装具体分段位置详见分段示意图。现场预制在暂设平台上进行。

现场预制需采用400t履带吊配合，两塔10段吊装采用400t履带吊完成。 其中减压塔下段立置组成吊装段时为倒装完成，正式安装时需采用400t履带吊主吊。250t吊配合翻个，第一次放平，再由400t履带吊主吊250t吊配合完成翻转，250t吊摘钩，400t履带吊主吊，转向，起钩，安装就位。
