There exist different kinds of natural active components in crude oil, such as organic acids, ester, nitrogen containing heterocyclic compounds (NCHC) and so on.Most studies have been reported on synergism for lowering IFT between organic acids and added surfactant, however, few reports are given on that of nitrogen containing heterocyclic compounds (NCHC).For this purpose, the separation method of NCHC in Daqing crude oil is firstly established and then its synergistic effects with alkyl benzene sulfonate for lowering interfacial tension are investigated.
