Hydrogen Effect on Remaining Life of Hydroprocessing Reactors
Source abstract
Abstract
Old vintage 2.25Cr-1Mo steels used for high-temperature/pressure hydroprocessing reactors have a high potential for temper embrittlement. The cracks caused by hydrogen embrittlement (HE) have been experienced in a stainless steel (SS) overlay and base metal of hydroprocessing reactors. In this paper, the temper embrittlement behavior during long-term service is discussed using the results of isothermal temper embrittlement tests up to 30,000 h of exposure. HE susceptibility of base metals, i.e., the thresohld stress intensity factor KIH, and hydrogen-assisted crack growth rate behavior are also discussed. Based on the experimental data obtained, the remaining life assessement of a 2.25Cr-1Mo steel hydroprocessing reactor was analyzed from knowledge of HE.
