Abstract:The present study provides some important thermodynamic and kinetic data for the CO2 hydrate formation in flow system. Images were obtained dynamically using Magnetic resonance imaging (MRI) system, with a fast spin-echo multi-slice scan sequence (FSEMS). The CO2 hydrate dissociation rate was quantified using MRI mean intensity of liquid water. The saturation of residual liquid water, CO2 hydrate and CO2 gas during the dissociation of CO2 hydrate were also quantified using MRI data. The highest CO2 hydrate saturation was 58% in the first process, and 26% for the second process in this investigation. (C) 2013 The Authors. Published by Elsevier Ltd.
