Experimental Investigation of Rate of Corrosion in the Reboilers in Refinery and Petrochemical Factories

Akbar Darvishi*

To prevent the rate of corrosion, as well as to maintain various devices, a series of materials are used as inhibitors. If these materials are used, the lifespan of tools and devices will be increased and economic costs will be reduced. In this study, a new inhibitor that can be used instead of hydrazine was used. This inhibitor is called levoxin-15 and can be used to prevent corrosion caused by oxygen in steam tanks. In addition, the results illustrate that with increasing the concentration of hydrazine from about 20 mg/l to 30 mg/l and also the concentration of levoxin-15 from about 78 g/ m³ to about 88 g/m³, the operating time increases significantly. Also, results state that with increasing acidity from about 11 to 15, the relative corrosion rate will increase almost as a quadratic function to about 178 times.
