SBIR Phase II: Multilayer Membrane-Based Permeation for Cost-Effective Olefin/Paraffin Separation

该SBIR第二阶段项目的重点是烯烃/烷烃分离。乙烯和丙烯的产量比任何其他有机化学品都大。一种新的膜系统正在开发中，该系统具有高烯烃回收率、极高的烯烃通量、与传统的促进传输膜相比大大提高了烯烃/烷烃的选择性和长期运行稳定性。在第二阶段，将演示一个实验室原型。将该膜系统集成到一个烯烃装置中，将以更节能和经济的方式大幅提高乙烯、丙烯和丁二烯的质量。用这种膜工艺，只需少量的后处理，就可以很容易地生产聚合级烯烃。经济分析表明，将拟议的膜系统纳入乙烯装置可以显著降低整个装置的资本和运营成本。由于降低了能耗，这种膜过程将相应地减少温室气体二氧化碳的排放。

This SBIR Phase II project focuses on olefin/paraffin separation. Ethylene and propylene are produced in larger quantities than any other organic chemicals. A new membrane system is under development, which provides high olefin recovery, extremely high olefin fluxes, drastically improved olefin/paraffin selectivities over conventional facilitated transport membranes, and long-term operation stability. During Phase II, a laboratory prototype will be demonstrated. Integration of this membrane system into an olefin plant will drastically improve ethylene, propylene and butadiene in a more energy efficient and economical way. Polymer-grade olefins can be easily produced with this membrane process with minor post-treatments. Economic analysis showed that incorporation of the proposed membrane system into an ethylene plant can drastically reduce capital and operating costs of the entire plant. As a result of reduced power consumption, this membrane process will correspondingly reduce emission of greenhouse gas CO2.
