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 Cto Chydrocarbons in the presence of an isomerization catalyst and hydrogen under isomerization conditions to produce a 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 an exchange stream to provide an absorber overhead stream and absorber bottoms stream comprising chlorides. The absorber bottoms stream is passed to the isomerization reactor. The liquid isomerate stream is passed to a deisohexanizer column to provide an isomerate product and deisohexanizer side stream.

Processes and apparatus for isomerizing hydrocarbons

Processes and apparatus for isomerizing hydrocarbons are provided. The process comprises isomerizing the hydrocarbon feed stream in the presence of an isomerization catalyst and hydrogen in an isomerization zone under isomerization conditions to produce an isomerized stream. The isomerized stream is stabilized in a stabilizer column to provide a stabilizer off-gas stream and a liquid isomerate stream. The stabilizer off gas stream is passed to a net-gas scrubber to obtain a net gas scrubber off-gas stream comprising hydrogen and C-Chydrocarbons. The net gas scrubber off-gas stream is contacted with an absorber liquid feed comprising Cto Chydrocarbons in an absorber column to provide an absorber overhead stream comprising predominantly hydrogen and an absorber bottoms stream comprising predominantly light ends, the light ends comprising C-Chydrocarbons. The absorber overhead stream is passed to the isomerization zone as make-up hydrogen.
