Abstract

Abstract: In order to prepare high purity isobutane product from C4 fractions, a new process that combines extractive distillation, hydrogenation and product separation systems was designed. The best process flow scheme and operation parameters were determined by simulation, providing guidance for on-site operation of the plant. By optimizing the heat exchange network, the steam consumption was reduced by 20%, the cooling water consumption was saved by 2000 t/h, and an accumulative economic benefit of 50 million RMB was created annually. This route has become a new way for the rational utilization of C4 resources in China.

Key words: C4 fraction, extraction, hydrogenation, separation, isobutane
