| Presentation Title |
Electrical capacitance tomography and multiphase flow measurement |
| Abstract |
| Among various industrial tomography modalities, electrical capacitance tomography (ECT) is the most mature and has been used for many challenging applications, in particular for multiphase flow measurement. ECT is based on measuring very small capacitance and reconstructing the permittivity distribution in a cross section of an industrial process, such as a multiphase flow. Compared with other tomography modalities, ECT has several advantages of no radioactive, fast response, both non-intrusive and non-invasive, withstanding high temperature and high pressure and of low-cost. Because of very small capacitance to be measured (much smaller than 1 pF) and the “soft-field” nature, ECT does present challenges in circuit design, and solving the inverse problem. Our latest AC-based ECT system can generate online images typically at 100 frames per second with a signal-to-noise ratio (SNR) of 73 dB. Examples of industrial applications include the measurement of gas/oil/water flows, wet gas separation, pneumatic conveyors, cyclone separators and fluidised beds for pharmaceutical manufacturing and clean use of coal by circulating fluidised bed combustion and methanol-to-olefins conversion. During this talk, ECT will be discussed from principle to industrial applications, together with demonstration of an AC-based ECT system. |
