Butadiene is commonly recovered from mixed C4 streams using solvent extraction. Butadiene is a monomer prone to polymerization, and the most common limitation during butadiene production is the formation of polybutadiene through unwanted polymerization. Tars consisting of solvent degradation products, and often antifoams, also contribute to fouling.

The Nalco Water solution offers chemical treatment, extensive performance monitoring, sample analysis and system audits (upon request) to mitigate the impact of butadiene polymerization.  Our programme does not guarantee elimination of risk as there are numerous mechanical and operational parameters that operators must follow that are outside of our scope.

Nalco makes no warranties with respect to crystalline polymers, including but not limited to popcorn polymer and other crystalline polymers as well as polybutadiene peroxides. Customer is solely responsible for controlling oxygen ingress as well as identifying and remediating any stagnant areas or piping segment that are open to the process but that do not have flow through it “e.g. dead-legs.” Customer is solely responsible for complying with applicable laws and protocols for the safe handling, transportation, and storage of butadiene/Crude C4 as described in the Butadiene Product Stewardship Guidance Manual published by the American Chemistry Council.
