The higher boiling point also extends the flexibility of the process in terms of the feedstock composition by allowing for the processing of components with higher boiling point ranges. The normal boiling points of NMP and sulpholane are 475 K and 560.5 K, respectively [23]. In the sulpho...
A method for recycling N-methylpyrrolidone (NMP) from a gas by utilizing a high boiling point solvent, comprising: spraying a high boiling point solvent into an absorption apparatus from the top of the absorption apparatus, pumping an NMP-containing gas into the absorption apparatus from either ...
An organic electrolytic solution according to an embodiment of the present invention includes: a lithium salt; an organic solvent containing a high dielectric constant solvent and a low boiling point solvent; and a compound represented by formula (1): where each of R1 and R2 is independently a...
Furthermore, the recovered NMP and absorption solvent with the high boiling point can be reused. According to the method disclosed by the invention, the NMP in the gas can be efficiently recovered, and the recycling of the solvent with the high boiling point and the NMP can be realized, ...
This invention relates to an improved process for the exraction of special boiling point (SBP) solvents from naphtha range petroleum fractions which comprises, (a) Dearomatizating a naphtha range petroleum fractions by passing countercurrently N-methylpyrolodone (NMP) containing water in an amount ...
