抽提蒸馏塔与再沸器的平面布置及管道设计

Layout and Piping Design of Extractive Distillation Tower and Reboiler

以某公司0.55Mt/a芳烃抽提装置为例,介绍了抽提蒸馏塔与其中段再沸器、塔底再沸器的平面布置及管道设计的特点。满足工艺要求并在工艺校核后,确定再沸器的安装高度。采用支耳处设置弹簧、取消螺栓孔以及增加聚四氟乙烯板等方法,来消除竖向和横向应力,为同类设备的管道设计工作提供参考。

This paper gives an example of 0.55Mt/a aromatics extract unit to present the equipment layout and piping design of extractive distillation tower,middle section reboiler and bottom reboiler.The installing height of middle section reboiler need to meet the process demands and checking.Using spring support,canceling bolt holes and putting Polytetrafluor ethylene at the supporting plate of reboiler can eliminate vertical and horizontal stress.These will provide a good reference for the pipe engineering design of similar equipment.
