Title: Enhanced Oxidative Dehydrogenation of Ethane with Facilitated Transport Membranes for Low Cost Production of Ethylene

Abstract

This SBIR program has been extremely successful. We have met or exceeded all of the key objectives. We have successfully demonstrated the product and process feasibility. Compact Membrane Systems proposed a membrane separation technology which can efficiently separate ethylene from ethane in the presence of H 2O and CO 2. The CMS ethylene/ethane separation will significantly improve the economics of the Oxidative Dehydrogenation (ODH) process. We have developed membranes with high ethylene flux and high ethylene/ethane selectivity. These membranes have also shown good resistance to high concentration CO 2 and CO. Economic analysis shows at least **% cost savings compared with conventional distillation used for ethylene/ethane separation. Given our success to date, we have been able to establish key direct partnerships with other collaborators. The primary objective of the Phase I program was to develop a stable membrane that is capable of providing very efficient and cost effective production of ethylene from ethane. The CMS fluorinated membrane developed during this program was found to be able to provide very good C 2H 4/C 2H 6 selectivity and outstanding C 2H 4 permeance. With the development of the fast and highly selective ethylene CMS membrane, we have achieved all our Phasemore » I program objectives. This is especially true of the estimated cost of ethylene production that is projected to be over **% less than the conventional method (distillation) at scale applications (** Nm3/h). The final result is better than the Phase I goal of 30% less. In summary, during the Phase I, we developed a CMS membrane with a high C 2H 4 permeance good C 2H 4/C 2H 6 selectivity. The stability and anti-fouling ability of the CMS membrane was demonstrated by exposing the membrane to a C 2H 4/C 2H 6 mixture gas for 7 weeks. A membrane based ODH production and separation system was designed and the economic and engineering evaluation using the VMGSim models predicted a cost of $***. As previously stated this is at least a 35% cost reduction from the conventional methods and higher than the Phase I goal (25% cost reduction). The successful Phase I research attracted the interest from several major industrial players who are willing to provide partnership and support of further research. Successful development of the fluoropolymer membranes for C 2H 4/C 2H 6 separation in the process of ODH will provide significant benefits to the public: 1. Development of a highly economically profitable use of shale gas resource; 2. More economic growth and job creations based on the rich shale gas resource in US; 3. Huge energy savings compared with the conventional production of ethylene.« less
