Methods and apparatuses for isomerization of paraffins
Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of compressing a C4− hydrocarbons-containing stabilizer vapor stream to form a compressed C4− hydrocarbons-containing stabilizer stream. A C4 hydrocarbons-containing feed stream that comprises unbranched C4 hydrocarbons is contacted with a chloride-promoted isomerization catalyst in the presence of hydrogen to form a branched C4 hydrocarbons-containing reaction zone effluent. At least a portion of the compressed C4− hydrocarbons-containing stabilizer stream is combined with the branched C4 hydrocarbons-containing reaction zone effluent to form a C4 hydrocarbons-containing combined stream. The C4 hydrocarbons-containing combined stream is separated into a C3− hydrocarbons-containing stabilizer vapor stream and a C4 hydrocarbons-rich product stream that comprises branched C4 hydrocarbons.
