*** 9761414 Lyon This Small Business Innovation Research Phase I project is directed at development of a liquid absorbent process for the selective separation of xylene isomers from mixed-isomer streams. The program builds on previous Bend Research work aimed at the separation of N2 from natural gas. Focus will be on the development of liquid absorbents for the separation of p-xylene from mixed-xylene streams, which are produced in petrochemical plants during the cracking of petroleum fractions. In Phase I, candidate absorbents will be screened and their performance evaluated using an in-depth economic and engineering model developed in previous work. In Phase II, the performance of the best absorbents will be optimized to achieve the properties and performance needed for a successful commercial process. This process promises to offer major cost advantages for the production of p-xylenes. More than 5 billion pounds of p-xylenes are consumed annually. Because it should be applicable to other types of separations such as ethylene/ethane, propylene/propane and branched/straight-chain olefin isomer separations, it could streamline petrochemical manufacturing processes by debottlenecking existing facilities. ***

*9761414里昂这个小型企业创新研究第一阶段项目旨在开发一种液体吸收工艺，用于从混合异构体流中选择性分离二甲苯异构体。该计划建立在之前Bend Research旨在从天然气中分离氮气的工作基础上。重点将放在开发液体吸收剂，用于从混合二甲苯蒸气中分离对二甲苯，这些混合二甲苯蒸气是石油化工厂在石油馏分裂解过程中产生的。在第一阶段，将筛选候选吸收剂，并使用先前工作中开发的深入经济和工程模型评估其性能。在第二阶段，最好的吸收剂的性能将得到优化，以实现成功的商业过程所需的性能和性能。这一工艺有望为对二甲苯的生产提供重大的成本优势。每年消耗的对二甲苯超过50亿磅。由于它应该适用于其他类型的分离，如乙烯/乙烷、丙烯/丙烷和支链/直链烯烃异构体分离，它可以通过消除现有设施的瓶颈来简化石化生产流程。***
