Development and Applications of Custom Amorphous Fluoropolymers (CAF)

摘要

Ethylene and propylene are the major chemical industry raw materials and consume a great deal of energy during production. The separations of these materials are some of the costliest, most energy intensive, and most technically difficult separations in the industry. The technology currently employed for the separation of ethylene and propylene from paraffins is distillation and is estimated to consume 250 trillion BTU/year of energy. A membrane based olefin-paraffin separation technology has the potential to provide substantial economic benefit to petrochemical industry and drastically reduce the energy required. Membrane processes utilizing facilitated transport membranes have been extensively studied for separating olefin/paraffin mixtures. While separations have been demonstrated in the laboratory, problems with membrane stability have prevented development of commercial systems..
