This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical absorption has been considered as a promising technology for carbon dioxide (CO2) capture from different industrial waste gases. However, this technology has not been widely commercialized due to its high capital and operational costs, especially the cost for solvent regeneration. Studies have been focused on developing more efficient gas/liquid contactors or superior solvents that require less energy for regeneration. Aqueous ammonia (NH3) has been recently studied as a CO2 absorption solvent in many traditional gas/liquid contactors due to its lower cost and low energy requirement for solvent regeneration compared to traditional amine solutions. Since membrane contactors offer more advantages than traditional gas/liquid contactors, it could be more efficient and economic to capture CO2 using aqueous ammonia as a solvent in a membrane contactor. However, little research has been reported in this field. The main objective of this research is to investigate the CO2 absorption performance of aqueous ammonia in a hollow fiber membrane contactor. In order to achieve this research goal, a number of lab-scale CO2 absorption experiments were conducted using aqueous ammonia and monoethanolamine (MEA) as absorption solvents in a membrane contactor fitted with polytetrafluoroethylene (PTFE) hollow fiber membranes at ambient temperatures. The CO2 absorption performance was evaluated in terms of the volumetric overall mass transfer coefficient (KGav) under different operating parameters. The absorption performance of aqueous ammonia was compared to that of MEA solvent under the same experimental conditions. The longterm membrane stability was evaluated by continuously running the CO2 absorption experiments using aqueous ammonia as a solvent for up to ten hours.

Download or read book Modeling and Experimental Study of Carbon Dioxide Absorption stripping in Gas LLiquid Membrane Contactor written by Nihmiya Abdul Rahim and published by . This book was released on 2015 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas consists primarily of methane (CH4) but it also contains considerable amounts of contaminating compounds mainly carbon dioxide (CO2). The presence of CO2 reduces the heating value of the gas and due to its acidic character causes several operational problems. Hence the removal of CO2 from natural gas is crucially important. The focus of this research work is to investigate the potential for the energy efficient and effective separation of CO2/CH4 gas mixture via lean solvent and regenerating of the rich solvent through absorption/stripping mechanism taking place in a hollow fiber gas liquid membrane contactor process (GLMC) which combines the advantages of membrane technology with those of absorbent liquid. In a gas liquid membrane contactor the microporous membrane acts only as an interface between the gas and liquid phases. In this study primarily polyvinylidene fluoride (PVDF) hollow fiber membranes were fabricated via thermally induced phase separation (TIPS) method and the fabricated membranes were characterized using several membrane characterization techniques in order to optimize the membrane fabrication conditions. Then the membrane that had optimal performance was used in GLMC and absorption/stripping experiments were carried out in order to find the optimum operation window that gives higher absorption/stripping performance. Various absorbent liquids like different amino acid salts (AAS) and aqueous ammonia solutions were used as absorbent liquid other than conventional absorption liquids. To improve the stripping performance, enhanced CO2 desorption (based on pH-shift) was studied. Furthermore, a comprehensive mathematical model of GLMC was developed. viii The characterization studies revealed 28% PVDF membrane extruded at high temperature provides the optimum performance and addition of ethanol to the coagulation bath reduces the performance of the membrane. The absorption/stripping studies revealed module configurations and adopted operating parameters have great influence in absorption/stripping performance of GLMC. Further it has been identified AASs are potential absorption liquids in GLMC applications because it have lower potential of membrane wetting due to its high surface tension and good recyclability than the conventional absorption liquid while providing the same absorption performance. The absorption/stripping studies using aqueous ammonia revealed it can be used in GLMC applications. However the two main problems extensive membrane wetting and ammonia slip from the solution have to be overcome successfully. Enhanced CO2 desorption (based on pH-shift) studies revealed by reducing the CO2 rich solution pH the absorption liquid can be regenerated effectively. Finally the developed mathematical model well describes the GLMC process.
