ABSTRACT:
An apparatus for separating vaporous mixtures of hydrocarbons, water and emulsifier derived from the remediation of wellbore fluid, such as a mud containing solid particulate material in which the vaporous mixture is quenched with a hydrocarbon stream which is at a temperature above the boiling point of water and below the boiling point of the hydrocarbons in the vaporous stream. Most of the hydrocarbons in the vaporous stream and substantially all of the emulsifier are condensed into the hydrocarbon quench to form an oil stream. The water is recovered from the hydrocarbon quench as a vaporous stream and quenched with water. The quenched water and any residual heavier hydrocarbons are separated by phase separation.
