Abstract

There are some processes, such as corrosion, scale deposition, wax deposition and clathrate hydrate formation, which reduce the efficiency of transport processes in oil and gas pipelines. Strong efforts are being carried out to find better methods for preventing them. For instance, to avoid corrosion it is common to add specific molecules that form protective films on pipeline surfaces. However, it has been observed that the use of these corrosion inhibitors can induce wax deposition, and thus may exacerbate at least one of the other undesirable phenomena. In this work, by using molecular dynamics techniques we have studied the processes associated with the deposition of alkanes on a hematite surface, and the subsequent growth of an alkane crystal. Analogous calculations have also been performed for the adsorption of oleic imidazoline, which is used as a corrosion inhibitor. (C) 2000 Elsevier Science B.V. All rights reserved.
