BASF Butadiene Extraction Technology
The value of reliability
BASF Butadiene Extraction Technology based on NMP (N-methylpyrrolidone) as solvent defines the state-of-the-art technology for recovery of high purity butadiene.
The BASF Butadiene Extraction Technology process offers:
Low investment costs
Low operating costs
Highly innovation driven
Unmatched in operations
Tailored customer solutions
Since the solvent does not react with other products in the process, the BASF Butadiene Extraction process causes negligible fouling. Carbon steel provides ample resistance in all sections of the process. Furthermore, the process solvent is an excellent one for trace polymers created in all butadiene extraction processes. This keeps the equipment clean.
Compared to competing processes, the BASF Butadiene Extraction process builds up substantially fewer residues and impurities. For example, tar is not built up at all. Disposal costs are correspondingly lower. The BASF Butadiene Extraction process produces minimal wastewater.
Selective hydrogenation (e.g. BASF SELOP® Hydrogenation) can be integrated into the process in order to transform waste C4 streams into valuable butadiene, butenes and/or butanes. This boosts butadiene and raffinate yield to 100% or more.
