| Abstract: | To counter the invalidity of 1Cr18Ni9Ti tubes of HTS reboiler from corrosion in the CO2 removal unit of ammonia plant,a study on the essential cause of porous corrosion of reboiler tubes in hot potassium carbonate solution has been carried out by dynamic analogue at high temperature and high temperature plus back pressure methods; and the corrosion mechanism was to be clarified As follows from the foremetioned work,a treatment plan has been put forward. |
