Method for increasing the mobility of waxy crude oils |
| abstract |
The mobility of waxy crude oils is increased by cooling a mixture of the crude oil and an amphipathic additive from a temperature higher than the nucleation temperature of the crude oil at a rate less than 10* F. per hour to a temperature at which nucleation of wax particles causing high pour point is virtually complete. Preferred amphipathic additives are alkylated phenols and copolymers of ethylene with polar organic compounds such as acetate or acrylate esters. The increased mobility is characterized by reduced pressures required to start flow through a pipeline and reduced pressure drop in a pipeline after flow has commenced. |
