| titleOfInvention | Continuous method for separating a c4 cut |
| abstract | The invention relates to a continuous method for separating a C4 cut (C4) by means of extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK). A separating wall (TW), forming a first partial region (A), a second partial region (B) and a lower common column region (C), is arranged in the longitudinal direction of the extractive distillation column (EDK). According to said method, a head flow (C4H10) comprising butane is separated from the first partial region (A), a head flow (C4H8) comprising butene is separated from the second partial region (B), and a flow (C4H6) comprising the hydrocarbons from the C4 cut is separated from the lower common column region (C), said hydrocarbons dissolving more easily in the selective solvent (LM) than the butane and the butene. |
