UPGRADING AND EXTRACTION OF HEAVY OIL BY SUPERCRITICAL WATER

摘要

A method of producing a product oil stream comprising the steps of mixing the liquid product in the product mixing tank for a mixing residence time to produce a mixed liquid product, maintaining the mixed liquid product in the product separation tank for a separation residence time, separating upgraded hydrocarbons from the mixed liquid product in the product separation tank, where the separation residence time allows the upgraded hydrocarbons to separate from and float on top of a water layer in an inlet section of the product separation tank, operating the product separation tank such that the upgraded hydrocarbons flow over a weir, the weir configured to separate the inlet section from an oil collection section, withdrawing the product oil stream from the oil collection section, where the product oil stream comprises upgraded hydrocarbons, and withdrawing a spent water from the inlet section of the product separation tank.
