Chapter 3: Capture of CO2 127 Figure 3.11 Principle of the Clean Energy Systems cycle. The combustion of the fuel and oxygen is cooled by injection of liquid-water, which is recycled in the process. is needed on this proposed power cycle, but it shows significant potential for low capital cost and high efficiency. 3.4.5 Techniques and improvements in oxygen production Oxygen is the key requirement for any oxy-fuel combustion system. It is also a key technology for pre-combustion CO2 capture (see Section 3.5). In the next paragraphs, existing large- scale O2 production methods are described first, followed by emerging concepts aimed at reducing the energy consumption and cost. The very large quantities of oxygen required for CO2 capture using the techniques of oxy-fuel combustion and pre-combustion de-carbonization can only be economically produced, at present, by using the established process of oxygen separation from air by distillation at cryogenic temperatures (Latimer, 1967). This is a technology that has been practiced for over 100 years. 3.4.5.1 Cryogenic oxygen production Oxygen can be pumped as liquid and delivered as a high- pressure gas at up to 10 MPa. Pumped oxygen plants have largely replaced the oxygen gas compression systems. They have virtually identical power consumptions but in a pumped cycle, a high-pressure air booster compressor provides a means of efficiently vaporizing and heating the liquid oxygen stream to ambient temperature. Current plant sizes range up to 3500 tO2 d-1 and larger single train plants are being designed. Typical power consumption for the delivery of 95% O2 at low pressure (0.17 MPa, a typical pressure for an oxy-fuel application) is 200 to 240 kWh/tO2. There are numerous process cycle variations particularly for the production of oxygen at less than 97.5% purity which have been developed to reduce power and capital cost. Note that adsorption and polymeric membrane methods of air separation are only economic for small oxygen production rates. In a typical cryogenic air separation plant (Castle, 1991; Figure 3.12), air is compressed to a pressure of 0.5 to 0.6 MPa and purified to remove water, CO2, N2O and trace hydrocarbons which could accumulate to dangerous levels in oxygen-rich parts of the plant, such as the reboiler condenser. Two or more switching fixed bed adsorbers are used, which can be 3.4.5.2 High temperature oxygen ion transport membranes regenerated by either temperature or pressure swing, using in each case, a low pressure waste nitrogen stream. The air is cooled against returning products (oxygen and nitrogen) in a battery of aluminium plate-fin heat exchangers and separated into pure oxygen and nitrogen fractions in a double distillation column, which uses aluminium packing. Ceramic mixed metal oxides have been developed which exhibit simultaneous oxygen ion and electron conduction atPDF Image | CARBON DIOXIDE CAPTURE AND STORAGE
