Topic : ” Ultrasonic Tomography system for Liquid/Gas bubble Column”
Liquid/gas column or widely known as bubble column can be found extensively used in chemical industries such as in process bio-reaction, oxidation, hydrogenation, chlorination and alkylation. Several methods available for monitoring the bubble column, but most techniques encountered difficulties to measure large and irregular shaped bubbles. Therefore, there is a need for alternative monitoring instrument for liquid/gas column. Ultrasonic process tomography has been widely explored for imaging industrial two-phase flows, especially in liquid/gas applications. Several ultrasonic tomography setups have been constructed as monitoring tools for liquid/gas column. However, it is observed that mostly the setups have limitations of low spatial resolution due to limited number of measurement. In order to deal with the problems, this thesis focuses on the design and development of an ultrasonic tomography system that will employ a transceiver sensor arrangement to increase the number of measurement. Using signal processing circuitries to collect information from the sensor data; and Visual C++ as the software platform, the system performs real-time imaging on an experimental liquid/gas column. A novel image reconstruction technique namely Adjacent Criterion Method (ACM) was proposed to enhance the image spatial resolution. A number of experiments consist of static and dynamic profiles were used to evaluate the performance of the system. Several attempts to reconstruct 3D images of gas profiles have been carried out and some comparisons with the actual profiles had been made.
