  • Treatment of viscous crude oils
    Patent number: 4915819
    Abstract: Asphaltenes and/or wax and/or water are removed from crude oil by contacting the crude oil with an organic solvent to dissolve the crude oil and precipitate asphaltenes and/or wax and separate the oil and water. Solvent is then separated from the deasphalted and/or dewaxed and/or dehydrated crude oil.Removing asphaltenes, wax and/or water reduces the viscosity of the crude oil and it can then be transported, e.g. by pumping through a pipeline, with less expenditure of energy.
    Type: Grant
    Filed: September 9, 1988
    Date of Patent: April 10, 1990
    Assignees: The British Petroleum Compan plc, Intevep SA
