Heated inclined separation pressure vessel

A heated inclined separation pressure vessel, comprising:

• a shell having a longitudinal axis for receiving oil in which water is emulsified, gas is entrained and solid particulate is present, for the purpose of separating the water, gas and solid particulate from the oil;
• means for supporting said shell such that the axis is at an oblique angle to the horizontal, whereby the shell has an upper and a lower end;
• a lower head closing the lower end;
• an upper head closing the upper end;
• an elongated sleeve extending coaxially into the shell, the sleeve being closed at the upper end with a head and having an open lower end located at an intermediate position between the ends of the shell;
• an emulsion nozzle adjacent to the upper end for admitting emulsion to the elongated sleeve;
• a water nozzle adjacent to the lower end to purge water from the shell;
• a gas nozzle adjacent to the upper end to remove gas from the oil;
• an oil nozzle adjacent to the upper end to remove clean oil from the shell;
• a heat source comprising:
• an elongated heat tube bundle extending coaxially through the sleeve, the heat tube bundle having a plurality of heat tubes, the bundle having a lower end and an upper end, the lower end being an evaporator section and the upper end being a condenser section;
• a furnace wherein heat pipe fluids are evaporated.
