Review of Tomography Papers 8th World Congress of Chemical Engineering
28/10/2009
Gary Bolton (Senior Applications Engineer), Industrial Tomography Systems) recently attended the 8th World Congress of Chemical Engineering in Montreal, Canada, where he had the opportunity to meet with ITS users from Canada, Australia and the UK.
A number of papers were presented demonstrating the use of ITS technology. Bawadi Abdullah from the recent group of Prof. Soji Adesina, University of New South Wales, presented a paper using Electrical Resistance Tomography (ERT) to characterise the hydrodynamics of multi-phase stirred tank reactors. The stirred reactor was fitted with a novel gas entrainment impeller and filled with a 3-phase mixture of water, alumina and air. ERT was used to determine the effects of stirring speed and alumina loading on radial and axial gas distribution.
Chirag Dave, also from the group of Prof Adesina, presented a paper on the application of ERT to bubble columns to investigate the performance of various coalescence-inhibiting solutions.
Uka Oguh, a University of Birmingham EngD student sponsored by Johnson Matthey Catalysts (Billingham, UK) presented a paper on the novel concept of spectroscopic ERT. Measurements were performed on a 3-phase gas-solid-liquid system and it was shown that the two dispersed phases, gas and solids, could be differentiated by collecting electrical measurements at a range of injection current frequencies.
Paper details:
- ERT measurements of gas hold-up distribution in a bubble column with coalescence inhibiting solutions, B. Abdullah, C. Dave, T.H. Nguyen, C.G. Cooper & A.A. Adesina
- Hydrodynamics characterisation of multiphase stirred tank reactors using electrical resistance tomography, C. Dave, B. Abdullah, D.V.N. Vo, T.H. Nguyen, C.G. Cooper & A.A. Adesina
- Gas-liquid-solid characterisation – novel frequency sweep spectroscopy technique using ERT, U.I. Oguh, J.F. Hall, G.T. Bolton, M. Castillo & E.H. Stitt
BHR 14th International Conference on Multiphase Production Technology
Earlier this year ITS attended the 14th International Conference on Multiphase Production Technology hosted by BHR in Cannes France. This was an opportunity to demonstrate the capabilities of the z8000 platform with the new ITS flow loop. The scope of the conference is to highlight new research and developments in the area of multiphase flow.
Tillman Growth from the Institute of Thermodynamics, Leibniz University of Hanover presented a paper demonstrating the use of electrical capacitance tomography to measure gas volume fractions and flow patterns. His paper won the BP award for the most outstanding contribution to the conference. The details of the paper are as follows:
"Effects of dissolving and degassing phenomena on multiphase oil and gas boosting"
T. Groth 1, M. Reichwage 3, D. Mewes 2, A. Luke1
1 Institute of Thermodynamics, Leibniz University of Hanover, Germany
2 Institute of Multiphase Processes, Leibniz University of Hanover, Germany
3 Bornemann Pumps, Obernkirchen, Germany

12th International Conference on Environmental Remediation and Radioactive Waste Management
ITS also attended the 12th International Conference on Environmental Remediation and Radioactive Waste Management. Gary Bolton (Senior Applications Engineer) presented a paper on:
"Measurement of Solid-Liquid Mixtures Using Electrical Tomography Measurement Techniques"
Bolton, G. Stanley, S "Measurement of Solid-Liquid Mixtures Using Electrical Tomography Measurement Techniques" - Proceedings of the 12th International Conference on Environmental Remediation and Radioactive Waste Management October 11-15, 2009, Liverpool, UK.
The event also marked the launch of a new startegic partnership between ITS and Energy Solutions to develop new and existing opportunities in the nuclear sector.
