Patent number: 5677267Abstract: A thixotropic thermal insulating fluid includes a heavy hydrocarbon, water and oleophilic clay, wherein said heavy hydrocarbon is present in an amount of between about 75% to about 92% by volume of the fluid, said water is present in an amount of between about 5% to about 15% by volume of the fluid, and said oleophilic clay is present in an amount of between about 3% to about 10% by volume of the fluid. The fluid may be prepared by mixing water in an amount of between about 5% to about 15% by total volume of the fluid with oleophilic clay in an amount of between about 3% to about 10% by total volume of the fluid so as to provide a substantially homogeneous first gel product; and mixing said first gel product with a heavy hydrocarbon in an amount of between about 75% to about 92% by total volume of the fluid under agitation for a time sufficient to provide a second thixotropic gel product.Type: GrantFiled: November 16, 1995Date of Patent: October 14, 1997Assignee: Intevep, S.A.Inventors: Simon Suarez, Carlos Rios, Ignacio Layrisse, Jose Gregorio Tovar

Patent number: 4915819Abstract: 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: GrantFiled: September 9, 1988Date of Patent: April 10, 1990Assignees: The British Petroleum Compan plc, Intevep SAInventors: Maria L.

Patent number: 4806231Abstract: The salt content of crude oil is reduced by washing crude oil containing residual salt water with wash water of lower salinity than the water present in the crude oil and allowing the resulting mixture to settle into a layer of crude oil of reduced salt water content and a layer of saline water. The quantity of wash water employed is greater than 7.5% by volume of the crude oil.The saline water may be recycled and a proportion removed from the recycle stream and a corresponding quantity of water of lower salinity added.Washing with relatively large quantities of water results in the formation of a less stable emulsion. Consequently, less severe conditions are required to break it to recover the desalted crude oil.Type: GrantFiled: May 18, 1988Date of Patent: February 21, 1989Assignees: The British Petroleum Company p.l.c., Intevep S.A.Inventors: Maria L. Chirinos, David E. Graham, Ignacio Layrisse, Alan Stockwell
