| Abstract: | The reasons of a large numbers of welding seam splits in the regenerator/third stage cyclone system of heavy oil catalytic cracking unit are analysed. Correlated countermeasures to prevent splits and several reparation plans for occurred splits are proposed. The split states in regenerator of the heavy oil catalytic cracking unit of Daqing Petrochemical Complex and the key technology and measures of reparation are summarized. |
