AB  - This research aimed to study the effect of 0.1 M of HCl, H<sub>2</sub>SO<sub>4</sub> and NaCl solutions at 61&deg;C on the 2 4
thermal performance and corrosion behavior of commercially pure copper tubes in the used Shell and Tube Heat
Exchanger (STHE). The tests are performed with a counter-flow arrangement for 120 h. The flow rates for the
tube side solution (aqueous solution) and shell side solution (tap water) adjusted and kept constant at 150 and
50 L h<SUP>-1</SUP>, respectively. According to the obtained results, the greater decrease in thermal performance is
observed in HCl solution than in H<sub>2</sub>SO<sub>4</sub> solution and finally in NaCl solution with a decrease in percentage &epsilon;
were (11.6, 10.1 and 6.9), respectively. Besides, the results of visual inspection of the interior tubes walls
degradation and variation of the used aqueous solution characteristics are showed that the HCl acid solution
is more corrosive than H<sub>2</sub>SO<sub>4</sub> acid and NaCl salt solutions. The XRD analysis results revealed that the corrosion 2 4
products are formed by more than one reaction mechanism and formed different hydrated and complex corrosion
products.
