Abstract
The use of non-selective hollow fibers as a new type of structured packing materials in a distillation column was studied for olefin/paraffin separation. The < 40 cm long column yielded > 8% enrichment of propylene from a 30% propane/70% propylene mixture; and > 20% enrichment of iso-butane from a 50% n-butane/50% iso-butane mixture. It has the height of a transfer unit (HTU) as low as 10 cm and an overall mass transfer coefficient > 0.01 cm/sec with the transfer resistance mainly coming from the vapor phase. The low HTU was due to the high mass transfer area per unit volume, over 1100 sq m/cu m. The compatibility between hollow fiber polymer and light hydrocarbon solvent on the separation performance in the distillation process was also studied. The effect of morphology of hollow fibers on the separation efficiency in olefin/paraffin distillation is presented. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montréal, Quebec, Canada 8/23-27/2009).
