| 摘要 |
A use of a fluorocarbon polymer as a surface of a vessel or conduit in a paraffinic froth treatment (PFT) process, for reducing fouling. The foulant comprises asphaltenes. The surface has an average water contact angle of greater than 90 degrees, a standard deviation of water contact angles divided by the average water contact angle of less than 0.1, and impurities of less than 1000 ppmw. The fluorocarbon polymer may be a polytetrafluoroethylene (PTFE)-based polymer. The surface may be substantially free of colorants, fillers, and plasticizers.
