Abstract
Processes and apparatuses for separating chlorides from a butane product stream by removing chlorides from a portion of said feed stream in a rectification section of the separation zone. The rectification section may be in a rectification column which may be combined with a stripper column. Alternatively, a wall may be used to provide the rectification section in a fractionation column. The processes and apparatuses can be used in both new designs and revamped designs.
