New Regeneration Methods for Adsorption

摘要建议编号：9710553建议类型：研究人员发起的首席研究人员：菲利普·C·万卡特隶属关系：普渡大学这笔赠款是通过化学和运输系统司界面、运输和分离计划的分离和净化计划子要素授予的。首席研究员是普渡大学的菲利普·C·万卡特博士。本研究将对一种新的吸附柱再生方法进行评价。该方法使用热的纯吸附蒸汽来加热色谱柱。当被吸附的蒸汽在吸附剂上冷凝时，蒸汽中可用的潜热被用来加热色谱柱。使用冷惰性吹扫气体将吸附物从热床中吹出。与正常的蒸汽再生不同，加热和吹扫步骤是分离的。通过冷凝从吹扫气体中回收纯吸附物。净化气体在新的再生床中被净化并回收。将使用溶质运动理论(局部平衡分析)和数值解来预测再生。吸附剂的再生是控制商业系统成本的能源密集型步骤。建议的技术将显著降低能源需求，提高再生率，并提高工艺效率。这将对各种气体吸附和分离技术产生影响。

Abstract Proposal No: 9710553 Proposal Type: Investigator Initiated Principal Investigator: Philip C. Wankat Affiliation: Purdue University This grant is awarded through the Separations and Purification Program sub-element of the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The principal investigator is Dr. Philip C. Wankat at Purdue University. The research will evaluate a new method for the regeneration of adsorption columns. The method uses hot pure adsorbate vapor to heat the column. The latent heat available in the vapor is used to heat the column when the adsorbate vapor condenses on the adsorbent. A cold inert purge gas is used to purge the adsorbate out of the hot bed. Unlike normal steam regeneration, the heating and purge steps are decoupled. Pure adsorbate is recovered from the purge gas by condensation. The purge gas is cleaned in a newly regenerated bed and recycled. Solute movement theory (local equilibrium analysis) and numerical solution will be used to predict regeneration. Regeneration of adsorbents is an energy intensive step that controls the cost of commercial systems. The proposed technology should significantly reduce energy requirements, improve regeneration rates and enhance process efficiency. This would have an impact on various gas adsorption and separation technologies.
