DE-ASPHALTING PROCESS WITH A SOLVENT OF RESIDUAL HYDROCARBON OILS |
| 摘要 |
An asphaltene-containing residual hydrocarbon oil is deasphalted by means of a light hydrocarbon solvent. Heating of the resultant asphaltic phase for solvent removal is effected by heat exchange with the deasphalted oil previously subjected to sufficient heating in a furnace heated by flame. Fouling of the plant is thus avoided. |
