Abstract:
An apparatus for recovering and separating a mixed vaporous stream comprising hydrocarbons, water and emulsifier comprising:a first contact line in which a vaporous mixture of hydrocarbons, water and emulsifier is contacted with a liquid hydrocarbon to condense a portion of said vaporous hydrocarbons and emulsifier,a first vessel connected to said first contact line to collect said condensed hydrocarbons and emulsifier, and separate vaporous water therefrom,a first cooler connected to said first vessel to cool said condensed hydrocarbons and emulsifier from said first vessel,a filter positioned between said first vessel and said first cooler,said first cooler being connected to said first contact line to return a portion of said condensed hydrocarbons and emulsifier to said first contact line,a second contact line to receive vaporous water from said first vessel and to contact said vaporous water with liquid water to condense said vaporous water,a second vessel connected to said second contact line to collect said condensed water and remove non-condensibles,a second cooler connected to said second vessel to cool said condensed water, said second cooler being connected to said second contact line to return a portion of said condensed water to said second contact line anda kiln having a vapor collecting zone connected to said first contact line.
