Plant #1 > BD - BN1
The BD plant produces high value-added butadiene through the use of the mixed C4 produced from the naphtha cracking plant as raw material. Over 99.5 wt% of high-purity butadiene products are produced through the stages of the first, second extractive distillations and BD refining. Butadiene is primarily used as raw material for synthetic rubber.
■ Production process
01 MTBE Process (R2 Refining Process)
As c4 Raff passes through the R2 high-purity refining process, it eliminates iso-Butene by MTBE using MeOH.
02 BN1 Process
It is a refining process wherein Butene-1 is refined at 2 towers with high boiling point and 2 towers with low boiling point. Products generated from C4 Raff2 mtbe and butenone mtb are used as raw material for butenone.
