Hachmuth, H K; Hovis, K W

A method is described for controlling the temperature or pressure in the hydrocarbon phase of an acid catalyst settler vessel in a catalytic alkylation process, the method comprising: (a) introducing alkylation reactor effluent into the settler vessel; (b) continuously separating the effluent, in the settler vessel, into the upper portion and the lower portion; (c) continuously removing hydrocarbon as product from the upper portion; (d) continuously removing catalyst from the lower portion; (e) processing a portion of the catalyst removed in a catalyst rerun vessel; (f) recycling hot hydrocarbon vapor and hot catalyst vapor from the rerun vessel to the settler vessel; and (g) apportioning the amount of hot hydrocarbon vapor and hot acid catalyst recycled to the hydrocarbon phase to maintain the temperature or pressure with hot hydrocarbon vapor and hot acid catalyst vapor in excess of the amount suitable for recycle to the hydrocarbon phase, recycled to the acid catalyst phase.
