STUDY OF ATMOSPHERIC CONTAMANTION CORROSION RATE MONITORING IN INDUSTRIAL ENVIRONMENT NEAR THE REFINERY

One of the most common form of corrosion is Atmospheric Corrosion that depends on humidity, dust & gaseous impurities, which favor condensation of the humidity on the metal In this case study during 100 days , we use c. s coupons for monitoring that located in horizontal & vertical form. The rates of atmospheric corrosion in coupon no. 1 & 9 are generally upper than the others. Those coupons installed in aeration near the Zinc Product :fiu:tory. The rates of atmospheric corrosion in coupon no. 6 is generally lower than the others coupon . this coupon installed in the west of CCR unit . In NACE standard , this area is in T4 & T5 corrosion environment but in my case study the rate of corrosion is very lower than above mention ( C2 corrosion environment (NACE)) whit corrosion rate between 1 0 to 200 gr/m2 per years , of cause the rate of corrosion in first location ( coupon No. 1 & 9) increase about 100 % and we must attention this place.
