摘要

Abstract

A two-stage blade-packing rotating packed bed (TSBP-RPB) was designed and developed for the intensification of continuous distillation. The mass transfer parameters of the TSBP-RPBwere investigated using a chemisorption system. Continuous distillation experiments were conducted in the TSBP-RPB by the methanol-water binary system. Experimental results showed that values of the effective interfacial area and liquid-side mass transfer coefficient of the TSBP-RPB were 93-337 m

·m

-3

and 0.05-0.19 cm·s

-1

respectively. The height of equivalent theoretical plate (HETP) of the TSBP-RPB ranged from 1.9 to 10 cm. Moreover

the TSBP-RPB is easy to be manufactured

which shows great potential for the application of continuous distillation.
