Integration of an organic chloride decomposition reactor on the isomerization/deisobutanizer C5 drag stream

A process for producing i-butane comprising:

• sending a feed stream comprising butanes, hydrogen and an organic chloride to a butane isomerization reactor containing an isomerization catalyst to convert a portion of normal butanes in said feed stream to iso-butanes in an isomerized stream;
• sending said isomerized stream to a stabilizer column to produce a butane stream containing normal, iso-butanes and C5 hydrocarbons;
• and
• sending said butane stream to a deisobutanizer column to produce an isomerized upper stream comprising iso-butanes, an NC4 rich side draw stream, and a bottoms stream comprising a mixture of butanes, C5 hydrocarbons and said organic chloride;
• and
• sending said bottoms stream to an organic chloride decomposition reactor to produce an organic chloride decomposition stream comprising hydrogen and HCl.
