Heat exchanging equipment

Shell-and-tube heat exchangers and condensers with expansion joint on the shell for sulfuric acid productions

 

These heat exchangers are intended for cooling sulfuric anhydride (SO 3 ) and heating sulfurous anhydride (SO 2 ) while producing sulfur acid via contact process.
