REDUCING FOULANT CARRY-OVER OR BUILD-UP IN A PARAFFINIC FROTH TREATMENT PROCESS

摘要

A use of a foulant collector in a vessel or conduit in a paraffinic froth treatment (PFT) process. The foulant comprises asphaltenes. The foulant collectors are purposed to reduce build-up in the vessel or conduit and/or to reduce downstream foulant carry-over in the process. The surface of the foulant collectors may have an average water contact angle of less than 90 degrees. Additionally, together with such foulant collectors , a fluorocarbon polymer may be used as a surface of a vessel or conduit in the PFT process, for reducing fouling.
