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.

摘要 提案编号： 9710553 提案类型： 研究者发起的主要研究者： Philip C. Wankat隶属关系： 普渡大学 该补助金通过化学和运输系统司界面，运输和分离计划的分离和纯化计划子要素授予。首席研究员是Philip C.普渡大学的Wankat该研究为吸附柱的再生提供了一种新的方法。该方法使用热的纯吸附质蒸气来加热柱。当被吸附物蒸气在吸附剂上冷凝时，蒸气中可用的潜热用于加热柱。使用冷惰性吹扫气体将吸附物从热床中吹扫出来。与常规蒸汽再生不同，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质。吹扫气体在新再生的床中被清洁并再循环。溶质运动理论（局部平衡分析）和数值解将用于预测再生。 吸附剂的再生是控制商业系统成本的能量密集步骤。拟议的技术将大大减少能源需求，提高再生率和提高工艺效率。这将对各种气体吸附和分离技术产生影响。
