Fabrication and Examination for Hot-wall Hydrotreating Reactor(2)

This article described the brief situations of fabrication & development of hot wall hydrotreating reactor operation, dissertates structure character (plate and plate welding) in emphases of hot wall hydrotreating reactor and six significant problems which required to be solved, including hydrogen attack, hydrogen brittleness, high temperature & pressure hydrogen sulfide attack, crack due to sulphide stress crossion, stripping of overlayers and damage due to tempering brittleness of Cr-Mo steel,and the characters of welding material and main material which are used to solve the above six problems. It also described main fabrication points and nondestructive examination requirements, analyses the last headway of hot wall hydrotreating reactor.
