  • Method for removing water from crude oil containing same
    Patent number: 4789461
    Abstract: A method and apparatus for removing residual water from heavy crude oil comprising a casing, an inlet for admitting liquid crude oil into the casing so as to establish a liquid surface in the casing, an outlet passage for discharging dehydrated liquid crude oil from the casing, a heater in the casing for maintaining the liquid oil at a distillation temperature for evaporating water and light hydrocarbons, a vapor outlet for discharging a mixture of water vapor and light hydrocarbons evaporated from the crude oil, a spray device above the surface of the liquid in the casing for spraying incoming crude oil onto and in heat exchange contact with the surface of the heated oil in the casing, whereby water and light hydrocarbon vapors are distilled from incoming crude oil upon contact with the surface of the heated liquid crude oil.
    Type: Grant
