Abstract

Abstract: The simulation and optimization were conducted for a 567kt/a light naphtha isomerization unit using Pt/Cl-Al2O3 low reaction temperature isomerization catalyst. Based on the once through mode (OT) for isomerization reaction, the best flowsheet of de-isopentane (DIP) + (OT)+de- isohexane (DIH)+de-pentane (DP) was finally selected. The design RON of product is 91.23/90.77 (SOR/EOR), the design RVP is 96.50/95.15kPa (SOR/EOR), and the design product yield is 97.22/97.50 (SOR/EOR) lv%. The ideas and analysis methods in this paper can be used as reference for similar units in China.

Key words: C5/C6, isomerization, light naphtha, process design, flow optimization
