Absorption Of Co2 Through Hollow Fiber Membranes Using Aqueous Solutions Of Various Absorbents, Praveen Babu Kosaraju
Absorption Of Co2 Through Hollow Fiber Membranes Using Aqueous Solutions Of Various Absorbents, Praveen Babu Kosaraju
Theses
Absorption behavior of CO2 was studied in different hollow fiber membrane modules fabricated using Celgard (polypropylene) and poly(4-methylpentene-1) microporous hollow fibers. Pure water, aqueous solutions of poly(amidoamine) (PAMAM) dendrimer of generation zero and monoethanolamine (MEA) were used as the absorbent; the absorbent solution flowed through the fiber bore, the gas mixture of C02 and N2 flowed countercurrently on the shell side. The system consisted of absorption in one module and stripping with Helium in another module of the same fibers. The absorption characteristics of the dendrimer solution and the MEA solution were studied in the modules built of Celgard …

JTRP Technical Reports
This is Volume 2 of the Final Report for the project titled “Performance-Related Specifications for Concrete-Bridge Superstructures” dealing with the topic of High-Performance Concrete (HPC). The investigation of high-performance concrete included the development of optimized concrete mixtures and identifying their performance characteristics related to durability for the purpose of using these characteristics in performance–related specifications in the state of Indiana. The research effort described in this report was divided in two phases. Phase I was focused on development of concrete mixtures optimized with respect to selected performance-related parameters. During this phase, ten optimum concrete mixes have been identified from 45 …
