Liquid hydrocarbon treating (LPG/PP/BB) - ADIP process

Applications: Besides its use as a regenerative process for the reduction of H2S to very low levels in gases, the ADIP process is also used to selectively reduce H2S and COS to very low levels in liquid hydrocarbons, such as propane-propylene (PP), butanebutene (BB), LPG and NGLs. The process is based on regenerative absorption with an amine solvent in contact with the acidic feed. Removal of CO2 is also possible. H2S removal from LPG or NGLs down to 20 ppmwt or lower, and COS removal down to 5 ppmwt as sulphur are achievable.

Description: In liquid hydrocarbon treating (LPG, for example) the feed stream is contacted counter-currently with lean ADIP in a packed liquid/liquid extractor column. If COS is present in the LPG, removal of COS is achieved by a mixer/settler system. The lean ADIP solvent passes first through the mixer/settler system before entering the extractor. Co-current and counter-current mixer/settlers are used for COS removal. The treated LPG then passes through a coalescer to separate entrained ADIP solution. The rich ADIP solvent is flashed to remove entrained and/or dissolved hydrocarbons before passing to the regenerator. Stripping of the rich solvent is identical to that done in gas treating.
