“…ERT is suitable for visualizing the cleaning process as the electrodes which monitor fouling are mounted almost flush onto the interior of equipment surfaces where fouling occurs. Wang and Yin [22] summarized possible algorithms that could be utilized for identifying the endpoint of a CIP process. Hou [8] utilized ERT to monitor the removal of shampoo from pipework at 15 • C, a lower temperature than those typically used in a CIP process; and identified issues with monitoring the wall where there were no electrodes with conventional circular designs.…”

This paper investigates the feasibility of using Electrical Resistance Tomography (ERT) to visualize surface deposit during a Cleaning-In-Place (CIP) process, which is a common problem in various industries. A pilot scale cleaning rig with a purposely designed ERT test section was used for monitoring the pre-rinse CIP stage of cleaning milk paste adhering to a test section. The ERT test section comprises a CIP-ERT multi-linear sensor consisting of 4 planes of 8 electrodes. The Industrial Tomography System (ITS) P2000 ERT system was used to collect voltage data, which were processed in a MATLAB based ERT toolkit. Three dimensional (3-D) images were reconstructed using the L-curve Tikhonov method. A feasibility study was conducted to evaluate the performance of the CIP-ERT sensor. Image analysis showed that ERT is suitable for monitoring and visualizing the CIP process for the materials which foul similarly to milk pastes. The success of this work contributes to a time/energy efficient industrial process as the cleaning process can be visualized and over cleaning can be avoided.

In spite of decades of study and investigation, the research on tomography and electrical resistance tomography (ERT) in particular, remains to be focus of immense scientific significance. ERT provides the ability to measure conductivity distribution inside a process plant and delivers time evolving multidimensional information. Such important and otherwise inaccessible information enhances critical process knowledge whilst improving the design and function of the process equipment. ERT has been employed in a variety of fields including chemical engineering. This paper reviews previous research carried out on the application of ERT within the chemical engineering arena. The applications are classified based on the objective of ERT measurements, the unit operations ERT has been utilized on, the media under examination, and also other technologies and data processing techniques used in combination with ERT. The objective of this taxonomy is to offer the reader with a broad insight into the current situation of ERT related research and developed applications in the chemical engineering field and to assist in the identification of research gaps for future investigation.
