| Abstract: | The corrosion causes of condenser-cooler in sulfur recovery unit are analyzed. The main corrosion factors are stress corrosion, fatigue crack corrosion, pore scale corrosion, acid corrosion, sulphuration corrosion, tec.. Based on the analytic results, some measures for corrosion protection are suggested, e.g. improvement of connection structure between heat exchanger and pipeline plate, treatment of welded stainless steel pipeline and plate, proper design of unit to prevent corrosion, application of anticorrosive materials and proper operation technology. |
| Keywords: | sulfur recovery unit condenser-cooler corrosion countermeasures |
