Abstract

Abstract: UOP Penex-DIH low temperature isomerization technology was first adopted in 300 kt/a C5/C6 isomerization unit of SINOPEC Tahe Company to produce the gasoline blending component with RON≥85 using the C5/C6 light naphtha at the top of the pre-distillation column as raw material. This paper mainly summarizes the composition of raw oil and its impurities, operating conditions, properties of isomerized products, material balance and energy consumption of the unit from 2015 to 2018, and analyzes the existing problems in the operation, and puts forward suggestions for improvement and optimization.

Key words: light naphtha, low temperature isomerization, isohexane, octane number, vapour pressure
