Emulsification of Indian heavy crude oil using a novel surfactant for pipeline transportation

Abstract The most economical way to overcome flow assurance problems associated with transportation of heavy crude oil through offshore pipelines is by emulsifying it with water in the presence of a suitable surfactant. In this research, a novel surfactant, tri-triethanolamine monosunflower ester, w...
