| Abstract: | Because there is sulfolane,water and steam in the feed of EA-303 vertical heat exchanger,which resulted in tube problems occurred frequently.The main reasons are medium erosion and flushing,and the welding specification.The remodelling for EA-303 is performed in terms of operation,material and technique after analyzing and studying.Better effect was achieved to ensure life time extension of the exchanger. |
