Abstract
A novel adsorption–distillation hybrid scheme is proposed for propane/propylene separation. The suggested scheme has potential for saving up to ∼50% energy and ∼15–30% in capital costs as compared with current technology. The key concept of the proposed scheme is to separate olefins from alkanes by adsorption and then separate individual olefins and alkanes by simple distillation, thereby eliminating energy intensive and expensive olefin-alkane distillation. A conceptual flow schematic for the proposed hybrid scheme and potential savings are outlined.Keywords
