Effect of agglomerate size on oil removal during microwave treatment of oil contaminated drill cuttings / Igor S. M. Pereira in Industrial & engineering chemistry research, Vol. 50 N° 16 (Août 2011)

M. Pereira, Auteur ; John P. Robinson, Auteur ; Sam W. kingman, Auteur Année de publication : 2011 Article en page(s) : pp. 9727-9734 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Cutting  Pollution  Microwave Résumé : This paper presents new observations on the effects of agglomerate size on microwave treatment of drill cuttings. A continuous pilot scale microwave heating system was used at power levels from 17 to 42 kW and material throughputs from 190 to 300 kg/h. It was found that oil is preferentially removed from smaller agglomerates and that feed materials larger than 1 mm required up to 15% more energy to be remediated to the same levels of residual oil as < 1 mm particles. A further observation was a threshold energy consumption, below which there is no appreciable removal of oil from the coarser sizes. The industrial implications of this variation in efficiency are discussed, and explanations for these observations are presented based on interactions with the electric field and mass transfer.
