During a conventional heavy oil treating process, free water and the larger droplets of water in the emulsion are removed by application of heat, chemicals and residence time. The remaining emulsion usually contains small droplets of water (up to 10% BS & W).
The Flash Treater® has been designed to break that remaining emulsion (whether it is a slop feed or the outlet of a conventional treater) which may otherwise be impossible or too expensive to treat. Recovery of this untreatable heavy oil can effectively payout the Flash Treater® quickly.
The Flash Treater® recycles hot dry oil from its outlet to the incoming stream of wet oil. This hot oil will cause the majority of the incoming water to vaporize. The recycling of hot oil, the large volume of oil in the vessel, and the baffled heating path enable the Flash Treater© to handle substantial slugs of water and emulsion without foaming and unstable operation.
