A brief introduction was made on the general situation of styrene unit and refined styrene tower of SINOPEC Anqing Branch.The reasons for frequent leakage of the reboiler of the refined styrene tower were analyzed.It was concluded that the solid impurities generated during the maintenance construction entered the refined styrene tower still led to frequent leakage of the reboiler.In addition,the increase in polymer content in the tower also accelerated the leakage of the reboiler to a certain extent.
