1、 1 脱硫装置稳定塔设计 摘 要 本次设计主要针对 120 万吨/年催化汽油加氢脱硫装置稳定塔。 加氢脱硫过程作为原油后续加工的一项重要的加工过程， 脱硫装置稳定塔设备显 得尤为重要。因此严格要求该塔体在各个载荷工况下的强度必须合格。 本设计前部分对塔的各个结构件进行分析介绍， 并且确定了该结构件的结构以及 受力状态，确保该结构件适用于该塔体。该塔采用的是浮阀塔塔盘，一共 25 块塔盘， 塔径为 1900/3000 mm，塔高为 33047mm。主要设计参数为：设计压力 1.3MPa，设计 温度 275 等。承受的载荷有内压、地震载荷、风载荷，由于存在变径段，因此该塔 需要对不同直径塔段及该塔

2、段的封头的厚度进行计算和校核， 同时设计计算该塔体的 裙座。 进而对塔体的地震载荷，风载荷等进行稳定性校核。在满足强度要求的同时，还 需校核塔体的裙座，地脚螺栓，塔体与裙座的焊接处的强度，确保整个塔体的强度合 格。 最后绘制了装配图和两张零部件图。 关键词：关键词：稳定塔，原油加工，厚度设计，强度校核 2 The Design of Desulfurization Stability Tower Abstract This design mainly aims at of the stability tower 1.2 million tons/year of catalytic gasoli

3、ne hydrodesulphurization unit. Hydrogenation desulfurization process is an important process for subsequent processing of crude oil. The stability tower is particularly important. So the strength of the tower body must be qualified under various load conditions. We have introduced each structures of

4、 the tower and found the structure and stress state of the structure. The tower is flower valve tray. There are 25 pieces of tower tray and the diameter is 1900/3000mm, the height is 33047mm. For main design parameters, the design pressure is 1.3MPa. The design temperature is 275 . Carry loads of in

5、ternal pressure, seismic load and wind load, as the different diameter, so we should design the thickness of the different diameter of the tower and the shell cover, and then we should check it. At the same time, design and calculation of the tower body skirt Then we check the seismic load and the w

6、ind load of tower body. While the strength requirement is qualified, we still need to check the tower body skirt, anchor bolts, tower body and the skirt of the strength of the welds ensure that the whole tower body strength is qualified. Finally draw the two pieces of parts drawing and a piece of assembly drawing. Keywords: Stability Tower Crude Oil Processing Design of the Thickness Strength Check 3 目 录 1 前言前言 1 2 稳定塔的工艺流程及结构简图稳
