Application of Complex Surfactant Based on Cottonseed Oil as CO[sub]2[/sub]-Corrosion Inhibitor and for Removing Thin Oil Slicks from Water Surface
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 9
Abstract
The corrosion inhibition and adsorption behavior of sulfated fatty acid diethanolamine (SFADC) as complex surfactant on carbon steel in CO2-saturated 1% NaCl solutions was investigated using LPR corrosion rate. Inhibitor efficiency increased with increase in SFADC concentration. Maximum inhibition efficiency of the surfactants is observed at concentrations around its critical micelle concentration (CMC). The adsorption characteristics of the inhibitor were approximated by Langmuir isotherm. Petroleum-collecting and dispersing properties of the synthesized complex surfactant in diluted and undiluted form in waters of varying salinity (distilled, fresh and sea waters) have been studied.
