Wax formation and deposition in subsea crude oil piepline is most important problem in cold environments faced by petroleum industry. Significant research is been going on at industrial as well as academic levels to develop additives which are able to break the wax crystal structure or at least weakens it. Addition of cloud point depressants has been found to be an effective way of dealing with waxes. The main focus of this project is chemical control of wax gel formation by using cloud point depressants (pour point depressants) and to find the action mechanisms of cloud point depressants on Model oil systems. Novel cloud point depressants were used and dosed in model wax oil system. Glass vesel experiments were performed on it and samples were analyzed using spectrfluorometer, NMR and GC apparatus to identify the mechanisms of these inhibitors.
