retrofitting isomerization process using pinch analysis

Isomerization process is a quite excellent process for high-quality gasoline production# this paper aims at studying a new scenario for improvement of gasoline quality, reduction of co2 emission, and production of pentane solvent# the ron of case study is 85-87 and the case has two furnaces that produce 2#85×107 kg co2/year# in this scenario, instead of the ipsorb technic (adsorption section), separation using distillation columns is applied and co2 emission is reduced with eliminating the two furnaces# the calculated rons are 82#5 and 89#06 for the base-case study and new scenario showing 8% increase ron and the capacity of gasoline production increases by 16#6%# the other advantage of the suggested scenario is the production of pentane solvent commonly used for different industrial applications#
