Investigating MIDEA Corrosion Treatment on Carbonic Simple Steel in Amin Unit of Isfahan Refinery

α-MDEA corrosion characters in addition to operatory situation depend on its density. In this survey we investigate applying density effect of 10% to 30% weight on solvent corrosion situation on carbonic simple steel on collision or temperature different situation. Results shows that carbonic simple steel corrosion Rate is minimum in 10% density, but its passio film is unstable. Pasio film for stable in 37% density and stable on different temperatures and even on collision, because it's produce low corrosion rate in different temperature, density or collision, in this phase show that α-MDEA density minimum for creating acceptable situation of pasio film is equal to 31 wt%. In this density there is not any possibility for making Iron oxide and creating flow increase on the polarization curves passio Region.
