| 20110162722 | PROCESS FOR REDUCING THE RESTART PRESSURE OF STREAMS SELECTED FROM WAXY CRUDE OILS, WATER-IN-CRUDE EMULSIONS AND DISPERSIONS OF HYDROCARBON HYDRATES - For reducing the restart pressure of streams selected from waxy crude oils, water-in-crude emulsions and dispersions of hydrocarbon hydrates, at least partially structured, a mechanic disturbance is applied, in flow-stop conditions, on the streams, The temperatures are lower than the WAT (Wax Appearance Temperature) for the waxy crude oils and water-in-crude emulsions. The temperatures are laso lower than the forming temperatures of said hydrates and pressures higher than the forming pressure of said hydrates, for the dispersions of hydrocarbon hydrates. | 07-07-2011 |
| 20090101540 | PROCESS FOR THE CONVERSION OF HEAVY CHARGES SUCH AS HEAVY CRUDE OILS AND DISTILLATION RESIDUES - Process for the conversion of heavy charges such as heavy crude oils, tars from oil sands and distillation residues, by the combined use of the following three process units: hydroconversion with catalysts in slurry phase (HT), distillation or flash (D), deasphalting (SDA), characterized in that the three units operate on mixed streams consisting of fresh charge and recycled streams, by the use of the following steps:
