摘　　要：针对中国石油化工股份有限公司塔河分公司催化重整车间苯抽提装置预分馏塔再沸器内漏问题,从设备制造和工艺操作两方面进行了原因分析,断定温差应力和反复交变载荷作用是导致内漏的症结所在。在检修过程中采用补焊堵漏技术并进行水压试验,同时优化工艺操作条件,很好地解决了再沸器的内漏问题,延长了再沸器的运行周期。The prefractionator reboiler in aromatic extraction unit in SINOPEC Tahe Company experienced leakages. The cause analysis in respect of equipment fabrication and unit operation concluded that the internal leakage was the result of effect of differential temperature stress and frequent duty shirtings. The repaire welding, hydraulic testing and optimization of operating conditions have solved the leaking problems and extended the operating cycle of the reboiler.
