Publication number: 20190336959Abstract: The present disclosure provides a process for treatment a spent ionic liquid, comprising: mixing the spent ionic liquid with a first fluid medium and water to obtain slurry comprising a solid fraction and a liquid fraction; separating the solid fraction from slurry to obtain a filtrate and a residue comprising hydrated ionic solids; followed by drying the residue comprising the hydrated ionic solids at a temperature in the range of 60° C. to 120° C. to obtain treated ionic solids; and evaporating the filtrate to recover the fluid medium. The process of the present disclosure further comprises a step of contacting the treated ionic solids with at least one second fluid medium to separate an active ionic liquid.Type: ApplicationFiled: December 6, 2017Publication date: November 7, 2019Applicant: Reliance Industries LimitedInventors: Vibhuti DUKHANDE, Visvanath KOTRA, Parasuveera UPPARA, Pavankumar ADURI, Suresh IYENGAR, Prashant TANGADE, Akhilesh YADAV
