Abstract:

Processes for separating oxygen are crucial to many other processes, primarily due to the relevance of its component gases in many industrial processes. Nitrogen is used in the petrochemical industry, while argon is used as an inert gas mixture in welding and other electrical gadgets such as the light bulb. Argon, Oxygen (O2) and Nitrogen (N2) are all used in medical and industrial processes, including integrated gasification combined cycle (IGCC), oxyfuel combustion, ammonia, glass, and metal.

Abstract:

This thesis describes a novel microchanneled membrane that was fabricated using a mesh-templating phase inversion process. The microchanneled membrane showed remarkable oxygen flux, good mechanical strength and thermal compatibility. Control of the fabrication parameters and the formation mechanism are discussed. Further improvement in the oxygen flux was achieved by changing materials and coating catalysts. Finally, the different mechanisms of oxygen permeation in microchanneled membranes were studied regarding gas diffusion, and contributions from the microchannel walls.

Abstract:

This thesis is relying on modeling of MIEC membranes inside a gasifier and it seeks to find an appropriate configuration to use in gasification setup for pure oxygen production and use it inside the gasifier in a gasification process. Application of pure oxygen instead of air can play a key role in gasification processes. Since conventional methods for separation of oxygen such as cryogenic distillation are energy intensive and some of them cannot provide full purity for oxygen, an alternative method can be a good option. This substitute method which is the focus of this study, can be achieved

Abstract:

Ceramic membranes made from mixed ionic and electronic conductive oxide materials have received much attention over the last decade due to their ability to separate oxygen from air at 100 % selectivity. The flux through these mem- branes may be optimized by reducing their thickness. A porous support of the same composition is applied to ensure sufficient mechanical stability. The pro- cessing of these so-called asymmetric membranes is addressed in this work; for the technology to become attractive from a commercial point of view, a reliable and cost-effective processing procedure needs to be e

Abstract:

Dense ceramic oxygen separation membranes can pass oxygen perm-selectively at elevated temperature and have potential for improving the performance and reducing the cost of several industrial processes: such as the conversion of natural gas to syngas, or to separate oxygen from air for oxy-fuel combustion in electricity generation (to reduce NOx emissions and facilitate CO2 sequestration). These pressure-driven solid state membranes are based on fast oxygen-ion conducting ceramics, but also need a compensating flow of electrons.

In order to reduce the amount of pollution that is generated by burning fossil fuels alternative energy sources should be explored.

Other environmental concerns are slag dusting and chromium escape to the atmosphere.

碩士<br>國立成功大學<br>航空太空工程學系<br>102<br>The characteristic design of a Texaco gasifier, with a coaxial coal-slurry oxygen-jet nozzle and an outer annular oxygen-jet, has a significant influence on the gasification process. For the fuel-oxidant coaxial jet nozzle, the central oxygen-jet flow impinges on the coal-slurry stream and assists in the atomization of the coal slurry. The outer oxygen-jet, which splits the oxygen intake stream into two, makes an influence of the flame position and causes an effect of the gasification efficiency and coal conversion rate. In the study, numerical simulations of

Abstract:

碩士<br>中原大學<br>化學工程研究所<br>90<br>The plasma deposited nitrogen-containing polymers onto commercial poly-4-methyl-1-pentene (TPX) membrane and their application in O2/N2 separations were investigated. The first part of this study is the comparison of plasma-polymerized films from pure C2H2, C2H2/N2, C2H2/NH3, pure C2H6, and C2H6/N2 mixtures under the same operating condition. It was found that O2/N2 separation performance was drastically improved by nitrogen-containing plasma polymer. Highly cross-linked film was deposited from acetylene-based rather than ethane-based plasmas. Thus, the separ
