Abstract
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.
