New Pressure Swing Adsorption Processes

提案标题：新的变压吸附工艺建议编号：CTS-0327089首席研究员：菲利普·万卡特机构：普渡大学该项目的目标是基于精馏设计，为一种新的变压吸附(PSA)方案开发一个局部平衡理论。将使用商业模拟器对这一过程进行广泛的模拟。将对一些不同的变压吸附过程进行详细的计算机模拟，以确定新程序的适用范围。这项建议的研究建立在专利和公开文献中先前工作的基础上，以开发改进的变压吸附工艺，以提高弱吸附组分的回收率和强吸附组分的纯度。潜在地，这些工艺与目前的工艺相比具有显著的优势。拟议的研究将使用详细的模拟来描述分离问题，对于这些问题，新工艺与现有工艺相比是一个改进。减少压缩的新程序将包括在这些新的周期中。这个项目的设计也是为了产生更广泛的影响。除了对研究生的教育有益之外，还将开发新的方法来教授研究生和最终的本科生吸收。PSA和变温吸附的高级吸附模拟器将被引入到研究生水平的化学工程选修课中，使用计算机实验室作为讲座的一部分。成功研究的结果将是新的PSA设计，在商业化之前准备好进行中试工厂测试。

Proposal Title: New Pressure Swing Adforption ProcessesProposal Number: CTS-0327089Principal Investigator: Phillip WankatInstitution: Purdue UniversityThe objective of this project is to develop a local equilibrium theory for a novel pressure swing adsorption (PSA) scheme, based on a distillation design. Extensive simulations of the process will be done with a commercial simulator. Detailed computer simulations will be done for a number of different PSA processes to determine the range of applicability of the new procedure. Research in this proposal builds on prior work in the patent and open literature to develop improved PSA processes to increase the recovery of the weakly adsorbed component and purity of the strongly adsorbed component. Potentially, these processes have significant advantages compared to current processes. The proposed research will use detailed simulations to delineate separation problems for which the new processes are an improvement compared to existing processes. The new procedure for reducing compression will be included in these new cycles. This project is also designed to have a broader impact. In addition to being educationally beneficial for the graduate students, new methods to teach graduate and eventually undergraduate students adsorption will be developed. An advanced adsorption simulator for both PSA and temperature swing adsorption will be introduced into a graduate level chemical engineering elective using a computer laboratory as part of the lecture course. The results of successful research will be new PSA designs that are ready for pilot plant testing before commercialization.
