Abstract

The properties of trioctylmethyl ammonium dodecanedioate (TAD) as a corrosion inhibitor (CI) of API 5L X52 steel in production water (PW) were evaluated in steady state using weight loss and polarization techniques within a Reynolds number (NRe) interval ranging from 500 to 40,000. The highest obtained IE was 87 % at 100 ppm with NRe = 2500, whereas the lowest IE was 15 % at 10 ppm with NRe = 4000. TAD was classified as a mixed-type CI of API 5L X52 steel in PW. The \(\Delta G_{\text{ads}}^{^\circ }\) data established a relationship between the NRe and the adsorption process, confirming the occurrence of physical adsorption phenomena.
