It is found that the inhibition efficiency (IE) and coverage ratio of urea at 1.5 g/L increase by increasing the concentration of urea until reach 99.46% and 0.994, respectively. The corrosion rate is reduced with increasing the concentration of inhibitor until 1.5g/L; however, after that the corrosion rate increases. Urea inhibitor acts as a cathodic inhibitor.
The effect of the new natural corrosion inhibitor known as an aloe vera (mannose–6– phosphate) on... more The effect of the new natural corrosion inhibitor known as an aloe vera (mannose–6– phosphate) on the corrosion inhibitor for mild steel in (1 wt. % NaCl) was investigated by using potentiodynamic polarization measurement. Obtained results revealed that this compound was very good inhibitor and behave better in NaCl solution. Polarization studies showed that the aloe vera behaves as mixed type of inhibitor for mild steel in sodium chloride solution. The inhibition efficiency reached (81.81%) at concentration of (75 µml).
The methanation reactor in the state company of fertilizers south region in Basrah is modeled and... more The methanation reactor in the state company of fertilizers south region in Basrah is modeled and simulated. The one-dimension heterogeneous catalytic reaction model is predicated. The mole fraction, temperature, and pressure profiles are predicted by using a such model. Also, the profile of the effectiveness factor of the reactions are evaluated and it is reported that it decrease with the length of reactor. The results of simulated model show a good compatibility with the available industrial data.
