  • Method and apparatus for the purification of a hydrocarbon-containing stream
    Patent number: 9890336
    Abstract: A method for removing sulfolane from hydrocarbon streams by serial separation using raffinate wash column and at least one raffinate wash drum. The separation may be particularly useful in retrofitting existing separation facilities to produce motor fuels meeting the specifications requiring lower sulfolane content. A method is provided for the purification of a hydrocarbon-containing stream having a sulfolane therein. The method includes separating a first sulfolane-depleted stream from a hydrocarbon stream in a first counter-current separation unit and then separating a second sulfolane-depleted stream from the first sulfolane-depleted stream in a second counter-current separation unit. The first and second counter-current separation units are preferably different and chosen from a raffinate wash column or at least one raffinate wash drum. An apparatus for performing the methods is also described.
