ADISCUSSION ON THE PROBLEMS PRESENT IN IN  SERVICE  HYDROGENATION REACTORS

Abstract

Abstract: Thispaperintroduces materialandstructureofthe hydrogenation reactors, and analysesthe problems presentin use of hydrogenation reactors. Main factors which can lead to stoppingworkof reactors, are hydrogen attack, hydrogen embrittlement, temper embrittlement andstripsof overlap weldinglayer,andsomeproposalsare putforward forsafeoperation ofre actors. Finallyitissuggested thatitbe notenough only by advancing the reactor material,and adoptingthe new design and structureof reactorisimperative.

Key words: hydrogen attack, hydrogen embrittlement, strip ofoverlap welding layer
