Abstract

A METHOD IS PROVIDED FOR SEPARATING A C4 FRACTION (2) BY MEANS OF EXTRACTIVE DISTILLATION USING A SELECTIVE SOLVENT (1) BY WAY OF COUNTER-FLOW OF THE C4 FRACTION (2) AND OF THE SELECTIVE SOLVENT (1) IN A LIQUID PHASE IN A DISTILLATION UNIT (KI, KII), WHILE SEPARATING A HEAD FLOW (3) COMPRISING THE BUTANES AND BUTYLENES FROM THE C4 FRACTION AND A BOTTOM FLOW (6) COMPRISING THE SELECTIVE SOLVENT AND THE REMAINING COMPONENTS OF THE C4 FRACTION, WITH THE EXCEPTION OF THE BUTANES AND BUTYLENES, THE SELECTIVE SOLVENT BEING OUTGASED FROM THE FRACTION IN AN ADDITIONAL STEP, CHARACTERIZED IN THAT ENERGY IS EXTRACTED FROM THE DISTILLATION UNIT (KI, KI I) BETWEEN THE EXTRACTION POINT FOR THE HEAD FLOW (3) AND THE EXTRACTION POINT FOR THE BOTTOM FLOW (6).
