Processes and apparatuses for heating a feed stream for a reactor which has a charge heater. At least one process stream provides heat so that a pre-heated feed stream passed to the charge heater is a vapor stream. The process stream may be the heated stream from the outlet of the charge heater. Alternatively, the process stream may be the effluent stream from the reactor that has been heated.

Processes and apparatuses for heating a hydrocarbon feed stream for a reactor

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 providing a feed stream comprising C, Cand C+ hydrocarbons. The feed stream is separated to produce a first stream rich in Cand Chydrocarbons and a second stream rich in benzene and C+ hydrocarbons. The first stream is isomerized in the presence of isomerization catalyst and hydrogen in an isomerization zone under isomerization conditions to produce an isomerized stream. The second stream is contacted with a benzene saturation catalyst at benzene saturation conditions to produce a saturation effluent stream comprising cyclohexane.

This present disclosure relates to processes and apparatuses for transforming feedstock with high levels of benzene into a low-benzene content product that is suitable for gasoline blending. The benzene rich reformate stream is split in a reformate splitter and the benzene in the benzene rich reformate is saturated in a benzene saturation unit and the gases like hydrogen and LPG are recovered.
