Claim:
1. A process for removal of trace chloride contaminants in a reactor effluent in a catalytic dehydrogenation process, the process comprising: compressing the reactor effluent, comprising trace chloride contaminants, hydrocarbons having 3 to 5 carbon atoms and from about 5 to 500 wppm polynuclear aromatics, in a compressor to provide a compressed effluent; cooling or heating the compressed effluent to a temperature above the dew point of the compressed effluent, but below polymerization temperatures of the compressed effluent, to produce a cooled or heated compressed effluent, wherein the temperature to which the compressed effluent is cooled or heated is between 93° C. and 300° C.; introducing the cooled or heated compressed effluent into a chloride remover; adsorbing trace chlorides contaminants present in the cooled or heated compressed effluent in the chloride remover, to provide a treated effluent; and cooling the treated effluent in a cooler to produce a cooled treated effluent.
