1,3 Butadiene Process by BASF SE/ Lurgi GmbH

1,3 Butadiene is recovered from a crude C4 stream from olefins plants by extractive distillation. N-methylpyrrolidone (NMP) as the selective solvent substantially improves the volatilities of the components. Different process configurations are available. The C4 cut enters the pre-distillation tower, … Continue reading
