Abstract |
The report gives results of using liquefied-gas solvents in a pilot plant study to extract oil from mill scale (a steel mill by-product) and bleaching clay (a vegetable oil filtering media). The process, operated on a semi-batch cycle, involved two extractors and a solvent recovery system. The results of the extraction experiments demonstrated the feasibility of condensed gas extraction. Preliminary economics indicate attractive payback on full-scale plants: about 23 months for a mill scale extraction facility and 17 months for a bleaching clay plant. |
