| titleOfInvention | Process for the purification of ethyl tert-butyl ether combining a membrane process and a distillation |
| abstract | We describe a process for separating a mixture containing in particular ethyl tertiary butyl ether (abbreviated as ETBE), ethanol and C₄ hydrocarbons, in which the mixture to be separated is introduced into a debutanizer from which collects the C tête hydrocarbons at the top with a fraction of ethanol and at the bottom the purified ETBE; an ethanol-rich phase is drawn off laterally, which is sent to a permeation zone, the dense film of the membrane of which is constituted by a polymer of NN-dimethylaminoethyl methacrylate (abbreviated to DMAEMA) or a copolymer of DMAEMA with N- vinylcaprolactam (abbreviated NVCL) and / or with N-vinylpyrrolidone (abbreviated NVP); the ethanol-depleted retentate from this permeation zone is returned to the debutanizer and the permeate comprises in particular separated ethanol.n n n This process can be integrated into an ETBE manufacturing process, in which in particular the ethanol separated by the permeation step is recycled to the etherification reactor. The debutaniser can be replaced by a catalytic distillation column. |
