Toward a Preliminary Mechanistic Understanding of Co-Evaporation and Co-Condensation of Top-of-the-Line Corrosion Inhibitors

The mass transfer of continuously injected corrosion inhibitor (a complex organic mixture) for top-of-the-line corrosion (TLC) mitigation has been the subject of multiple research topics. These include the evaluation of the initial atomization of the inhibitor and the partitioning characteristics between the liquid and gas phases, as well as the effective performance of inhibitors at various distances from the injection point. However, current TLC modeling programs do not account for these effects, and a significant gap currently exists between the requirements of TLC inhibitors and accurate TLC modeling with corrosion inhibitors. To build a foundation for a mechanistic understanding of the mass transfer of TLC inhibitors, this paper reviews the recent progress in the study of the co-evaporation and co-condensation of organic mixtures with surfactants. During the evaporation and condensation process, a new phase is created. This paper discusses the use of surface tension as a promising new TLC inhibitor evaluation criterion, in addition to overall volatility, to improve TLC models.
