Abstract: The process design of the first imported 600 kt/a light naphtha isomerization unit is presented. The performances of various catalysts are analyzed and compared, the advanced Pt/Cl-Al2O3 catalyst is selected for this project and one through process flow is adopted. In this process, the design values for liquid yield is 97.01—97.28%, RON of isomerization product is 83.1—83.5, RVP of isomerization product is 100—103 kPa and energy consumption of the unit is 684.06 MJ /t(feed), all these values show that this unit is the most advanced one of the same type units in China.
