Effects of Block Copolymer Demulsifiers on Langmuir Films of Heavy and Light Crude Oil Asphaltenes

Three different n-heptane (n-C7) asphaltenes were extracted from three crude oils, two heavy and one light, and their film-forming properties at the air–water and heptane–water interfaces were investigated using a Langmuir trough. Surface pressure–area isotherms, compression–decompression cycles, an...
