Dehydration and desalting of heavy and viscous crude oil produced by in situ combustion. V.V. Popp and V.D. Dinulescu. SPE Production Facilities., May 1997, 12(2), 95--99.

The dehydration and desalting of heavy crude oil produced by in situ combustion with thermochemical and gas-stripping stages is discussed. Indirect heating of oil through concurrent contact with recirculated water from the process, heated with metal heaters, will preclude temperature variations caused by flow fluctuations in the feeding of the plant during the thermomechanical process. At the same time, the amount of mechanical impurities is decreased. Process efficiency is increased by the flue-gas-stripping stage. 4 refs.
