| Abstract: | A promising new process for the regeneration of solvents with ionic liquid by molecular distillation has been proposed. The
main advantage of this process compared with the classic stripping of acids with alkali solution is that the volatile organic
acid is recovered with a yield of about 88 % in the form of free acid, not as its salt. Furthermore, improvement on the yield
of the stripping can be assumed. The consumption of chemicals in stripping by molecular distillation is reduced. |
