<p>ENERGY CONSERVATION IN A BUTADIENE PROCESS A method is provided for the conservation of energy in a butadiene recovery and purification process in which part of the heat necessary for operation of the final butadiene finishing column is obtained by heat exchange with the hot vapor of the polar solvent used in the extractive distillation of the butadiene, the heat being that obtained by condensation of the hot polar solvent vapor to liquid.</p> |
