Observations and data regarding the intense corrosion and deposit phenomena of the carbon steel tube bundle of the heat exchanger are presented. The bundle ensures the cooling of the light fraction C1 - C5 from the top of the distillation column which carries out the removal of pentane and smaller derivates into the RC equipment. Chemical and mineralogical analyses confirm the aggressive action of the fluids flowing through the exchanger. Tests have been done in order to replace the carbon steel with austenitic stainless steel into the manufacturing process of the tube bundle. The corrosion behaviour of the selected metallic materials in recycled cooling water and technological fluids was monitored.
