Abstract
Severe tube damage was discovered in a heat exchanger in which tubes made from 90/10 CuNi (UNS C70600) had thinned and collapsed. The main cause of the failure was severe tube thinning due to hydrogen sulfide (H2S) corrosion. Sulfur was introduced into the shell side of the exchangerthrough a diisopropanolamine solution arrying more than the allowable percentage of H2S over a long time period.
