| Abstract: | 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. |
