重整装置原设计处理量为15万吨/年,由于原料限制,实际处理量只有12万吨/年左右,故设备没达到满负荷运转。另外,实际使用的脱戊烷塔是由原稳定塔改装的,塔的高度虽满足了设计要求,但塔板的开孔率比设计开孔率大,因此造成操作状态不佳,塔盘上的泄漏现象很严重,致使塔的分离效果差,回流量有时不能正常建立,严重影响产品的质量。经化验分析,塔顶带走大量芳烃,这对生产芳烃的装置是极不经济的。在1981年大检修时,对该塔的部分塔盘进行了堵孔,即1～30层的开孔率由11.2％
The original designed capacity of the reformer was 150,000 tons / year. Due to the limitation of raw materials, the actual capacity of the reformer was only 120,000 tons / year, so the equipment did not reach full capacity. In addition, the actual use of the pre-de-pentane tower is modified by the original stability of the tower, although the height of the tower to meet the design requirements, but the opening of the plate than the design hole rate, resulting in poor operating conditions, the tray Of the leakage is very serious, resulting in poor tower separation, reflux sometimes can not be established normally, seriously affecting the quality of the product. Laboratory analysis, the top of the tower to take away a large number of aromatic hydrocarbons, which is the production of aromatic hydrocarbons is extremely uneconomical. Overhaul in 1981, the tower part of the tray was blocked, that is, 1 to 30 layers of the hole from 11.2%
