“…Among these, ERT is the most attractive method owing to its inherent simplicity, high-speed capability, and rugged construction of the tomographer. ERT is sufficiently robust to cope with most industrial environment, hence it is widely used in various chemical engineering processes, including bubble columns (Wang et al, 2001), solid-liquid filtration (Vlaev et al, 2000), polymerization (Kaminoyama et al, 2005), cyclonic separation , photoreactors (Zhao et al, 2008), and in the mixing processes (Holden et al, 1998;Stanley et al, 2002;Ricard et al, 2005;Stanley, 2006;Stanley and Bolton, 2008;Pakzad et al, 2008aPakzad et al, , 2008b.…”

“…These are either mounted on a baffle, dip-pipe or around the pipe or vessel circumference. The most common method is electrical resistance tomography (ERT) which enables the visualization of three-dimensional conductivity distributions within the process unit in real time [145]. ERT is a relatively simple and inexpensive technique.…”

“…The measurement of gas and solids distribution in a 30-L laboratory vessel [148] has been demonstrated as well as the cavern formation in the mixing of opaque xanthan gum solutions [149]. ERT has been used to investigate the impact of hydrodynamic characteristics on the single-feed semi-batch crystallization rate of barium sulfate [145].…”

Online monitoring of polymerization reactions is not only important due to the high exothermic nature of most polymerization systems; the data gained also provides information on product composition and quality and control possibilities thereof. Many inline and online methods are still in development and are better suited for application on the laboratory or pilot-plant scale. Industrial polymerization plant environments pose additional technical and financial challenges and constraints for the use of such systems. Available methods and current developments are reviewed with regard to their practicability and usefulness under these aspects.

“…Combining two ionic materials into a solution can sometimes form a solid, which often causes large variations in electrical conductivity. By monitoring the conductivity change using EIT, the crystallization reaction process can be monitored [24][25][26][27]. The reconstructed conductivity tomogram can help to identify the reaction endpoint and ensure the chemical reactions are controlled precisely, aiming to improve the production yield.…”

One contribution of 10 to a theme issue 'Super-sensing through industrial process tomography' . Electrical tomography is a relatively new imaging technique that can image the distribution of the passive electrical properties of an object. Since electrical tomography technology was proposed in the 1980s, the technique has evolved rapidly because of its low cost, easy scale-up and non-invasive features. The technique itself can be sensitive to all passive electrical properties, such as conductivity, permittivity and permeability. Hence, it has a huge potential to be applied in many applications. Owing to its illposed nature and low image resolution, electrical tomography attracts more attention in industrial fields than biomedical fields. In the past decades, there have been many research developments and industrial implementations of electrical tomography; nevertheless, the awareness of this technology in industrial sectors is still one of the biggest limitations for technology implementation. In this paper, the authors have summarized several representative applications that use electrical tomography. Some of the current tomography research activities will also be discussed.This article is part of the themed issue 'Supersensing through industrial process tomography'.
