Characterization of Novel Carbon Foam Corrugated Structured Packings with Varied Corrugation Angle

Abstract

Carbon foam was utilized to develop corrugated structured packing in distillation for the first time. The hydrodynamics and mass transfer performance of CFP-400X and CFP-500W with 60 and 75°corrugation angle were determined by total reflux experiments. The results indicate that increasing the corrugation angle will improve the capacity but decrease the mass transfer efficiency. Comparisons among CFP-400X, SCFP-500X, BX-500, and B1-500X were made with respect to the performance of hydrodynamics and mass transfer. CFP-400X shows advantages in terms of capacity and efficiency compared with the other two metal packings. SCFP-500X exhibits a higher mass transfer efficiency than CFP-400X because of its superior wettability of test liquid which is supported by the liquid flow behavior experiment.
