The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

SINOPSIS

Plasma technologies for the destruction of ozone-depleting substances are reviewed. Particular attention is paid to the PLASCON process, based on an argon plasma produced by a dc plasma torch, which is used to destroy halons and chlorofluorocarbons in Australia and the UK. Three different approaches to modelling the destruction of ozone-depleting substances in a thermal plasma are presented: chemical equilibrium, chemical kinetic and fluid dynamic. Chemical equilibrium modelling does not accurately predict the products of the destruction process; however, the equilibrium mixing temperature is shown to be well correlated with the destruction and removal efficiency. The ratio of the feed rate to the plasma power also predicts the destruction and removal efficiency for a given oxidising gas. Chemical kinetic calculations are shown to give a good prediction of the products of the destruction process, while fluid dynamic modelling, which takes into account turbulent mixing and recirculating flow phenomena, is required to calculate concentrations of the different species within the reaction zone. The importance of interconversion of different ozone-depleting substances during the destruction process is demonstrated, and it is shown that the use of steam rather than oxygen as the oxidising gas in the process greatly reduces interconversion and improves destruction performance. Keywords: plasma waste destruction, thermal plasma, CFC, chlorofluorocarbon, halon, Montreal Protocol.
