| Abstract: | The three explosive factors exist during the urea pro- duction process in the urea plant, many extra large explosion events have occurred with severe loss; in this theme the event hidden trouble scope & reason and the utilzation limitation concerning the present prevention measures are analyzed in detail; the author now presents the new technology of hydrogen removal, which can prevent the explo- sion event from occurrence substantially, and should be the strong as- surance for the "safety production" and "operation without worry". |
