Iraq has a huge network of pipelines, transport crude oil and final hydrocarbon products as well as portable water. These networks are exposed to extensive damage due to the underground corrosion processes unless suitable protection techniques are used.
Chromium (VI) is commonly found in large quantities in wastewater, which is toxic to animals and humans and known to be carcinogenic, and that is why the recovery of chromium content in wastewater is necessary for environmental and economic reasons.Experimental measurements have been tested for prepared solution and the effluent of the General Company for Electrical Industries in batch ion exchange
Corrosion of carbon steel in acid (HCl) - salt (Na2SO4) solutions under flow conditions was investigated for a range of rotation velocity, 0 – 2000 rpm, and temperature, 32oC- 52oC, by using rotating cylinder electrode (RCE).The corrosion rate was determined by using both weight loss method and electrochemical polarization technique.
