Separation of conjunct polymer from volatile regenerant for ionic liquid regeneration

A process for separating conjunct polymer from an organic phase comprising:

• separating a mixture comprising an ionic liquid phase comprising ionic liquid and the organic phase comprising the conjunct polymer and at least one silyl or boryl compound in a gravity separator into a first ionic liquid stream and a stream comprising the organic phase containing ionic liquid;
• separating the stream comprising the organic phase containing ionic liquid in a coalescer into a second ionic liquid stream and an organic stream having an unreacted silane or borane compound;
• and
• separating the organic stream in a fractionation column into at least a first overhead fraction comprising unreacted silane or borane compound and a bottoms fraction comprising the conjunct polymer and at least a portion of the at least one silyl or boryl compound wherein separating the organic stream in the fractionation column into at least the first overhead fraction comprising unreacted silane or borane compound and the bottoms fraction comprising the conjunct polymer and the at least the portion of the at least one silyl or boryl compound comprises separating the organic stream in the fractionation column into at least the first overhead fraction comprising unreacted silane or borane compound, the bottoms fraction comprising the conjunct polymer and the at least the portion of the at least one silyl or boryl compound, and a fraction comprising at least a second portion of the at least one silyl or boryl compound;
• and either
• passing the bottoms fraction through a first adsorption zone containing an adsorbent comprising alumina, silica, aluminosilicate, activated carbon, and combinations thereof;
• recovering the at least the portion of the at least one silyl or boryl compound;
• or
• passing the organic stream through a second adsorption zone containing an adsorbent comprising alumina, silica, aluminosilicate, activated carbon, and combinations thereof;
• recovering a stream comprising unreacted silane or borane compound and the at least one silyl or boryl compound;
• separating the stream comprising unreacted silane or borane compound and the at least one silyl or boryl compound in a fractionation column into at least a second overhead fraction comprising the unreacted silane or borane compound and a second bottoms fraction comprising the at least a portion of the at least one silyl or boryl compound.
