The data collected in forms are intended exclusively for processing user requests and will not be used for any other purpose, always safeguarding their confidentiality, under the terms of the protection conferred by the aforementioned regulation. A supercritical fluid is a phase that occurs for a gas at a specific temperature and pressure such that the gas will no longer condense to a liquid regardless of how high the pressure is raised. The neatness of this process is that the combustion products are relatively gentle compared with ignition which produces a range of sulfur and nitrogen oxides.

Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent.Extraction is usually from a solid matrix, but can also be from liquids. Supercritical water provides a method to oxidize sewage in a closed system which will burn out all the organics in a wet waste stream. Ionic Liquid and Supercritical Fluid Hyphenated Techniques for Dissolution and Separation of Lanthanides, Actinides, and Fission Products, oai/?verb=GetRecord&metadataPrefix=oai_dc&identifier=info:ark/67531/metadc839287 International Image Interoperability Framework (IIIF) 94,000+ Vectors, Stock Photos & PSD files. The research project consists of the following tasks: Study direct dissolution of lanthanide oxides, uranium dioxide and other actinide oxides in [Tf solvation strength, no IL loss during back-extraction, and no organic solvent introduced into the IL phase. Find & Download Free Graphic Resources for Supercritical Fluid. This project is investigating techniques involving ionic liquids (IL) and supercritical (SC) fluids for dissolution and separation of lanthanides, actinides, and fission products.
