Numerical investigations have been carried out for a postulated enclosure fire scenario instigated due to methanol pool ignition in a chemical cleaning facility. The pool fire under consideration is radiation-dominated and poses a risk to the nearby

Uranium is used as a fuel for nuclear power plant and can be extracted from different ores, mainly acidic (silicious ore) and alkaline (carbonate ore). Recovery of uranium through acid leaching from silicious ore is well established, whereas, alkalin

In this paper, the liquid emulsion membrane extraction of molybdenum(VI) has been conducted in static mixer. The performance in LEM mode is compared to a conventional solvent extraction mode. The rate of extraction in LEM mode is found to be signific

Suitability of TBP for recovery of uranium(VI) from dilute HNO3 using LEM extraction is investigated. TBP co-extracts significant amount of HNO3 along with U(VI). Beyond a critical time, extraction of U(VI) ceases due to attainment of critical acid l
