Abstract
In a process for isomerizing a hydrocarbon feed in the presence of a metal halide catalyst and a hydrogen halide in which the reaction effluent is separated into a first liquid phase and an uncondensed first vapor phase, including hydrogen halide and noncondensable hydrocarbon gases, the first liquid phase is further separated into a second liquid phase and an uncondensed second vapor phase, including hydrogen halide, the uncondensed second vapor phase is recycled to the isomerization reaction and a portion of the uncondensed first vapor phase is at least intervally removed from the process to prevent buildup of noncondensable hydrocarbon gases in the system, improved operation is attained by passing an absorption liquid including a portion of the second liquid phase, from the second separation, a portion of the hydrocarbon feed or mixtures thereof, through the uncondensed vapor phase prior to venting the latter, to absorb hydrogen halide from the uncondensed first vapor phase, and absorption liquid utilized to absorb hydrogen halide from the uncondensed first vapor phase is recycled to the isomerization reaction.
