Processes for isomerizing hydrocarbons
Processes and apparatus for isomerizing hydrocarbons are provided. The process comprises isomerizing at least a portion of the hydrocarbon feed stream comprising at least one of C4 to C7 hydrocarbons in the presence of an isomerization catalyst and hydrogen under isomerization conditions to produce an isomerized stream. The isomerized stream is stabilized in a stabilizer to provide a stabilizer off-gas stream comprising chlorides and a liquid isomerate stream. At least a portion of the stabilizer off-gas stream is contacted with a dried feed stream to remove chlorides from the stabilizer off-gas stream. The dried feed stream is not cooled before absorbing the chlorides. A portion of the dried feed stream may bypass the absorbing section. A chiller is disposed on top of the vessel with the absorbing section.
