Abstract

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 m²·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.

Key words: Two-stage blade-packing rotating packed bed, Mass transfer, Distillation
