BUTADIENE
Solution

Butadiene

Nalco Champion pioneered process additives and treatment solutions for butadiene purification processes. Our industry-first innovations include antifoulants and antifoams tailored for extractive distillation technologies, comprehensive popcorn polymer management practices and environmentally friendly passivation programs. Our technical consultants have unmatched experience in butadiene processing and can assist your plant in reaching improved throughput and reliability of operations.

BUTADIENE ANTIFOULANTS

Nalco Champion is a global leader in controlling and mitigating the fouling of butadiene plants. We offer chemical treatment programs for all major butadiene extraction processes and isoprene extraction units. Our programs are adjusted to specific designs, customer requirements and plant limitations, and have been validated over more than twenty years of successful application. 

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. Vapor spaces with high butadiene concentrations are also vulnerable to popcorn polymer fouling.

The Nalco Champion solution offers:

  • A comprehensive treatment program for extraction section fouling control
  • An effective popcorn polymer control program
  • A Mechanical, Operational, and Chemical (MOC) approach to problem solving

In addition to our chemical program, we provide extensive performance monitoring, sample analysis and Best Practice Gas Analysis (BPGA).


BUTADIENE ANTIFOAMS

Foam control is integral to successful butadiene extraction. To be effective, antifoams must be insoluble in the extraction media and well dispersed at the liquid gas interface. Nalco Champion Fortis™ program offers a number of antifoams for the butadiene extraction process. These proven, high-performance antifoams are also cost competitive against commodity offerings.


BUTADIENE PASSIVATION

Foam control is integral to successful butadiene extraction. To be effective, antifoams must be insoluble in the extraction media and well dispersed at the liquid gas interface. Nalco Champion Fortis™ program offers a number of antifoams for the butadiene extraction process. These proven, high-performance antifoams are also cost competitive against commodity offerings.

Unwanted polymerization (fouling) during butadiene purification is a constant challenge for plant operators. During new equipment commissioning or turnaround, carbon steel equipment (tanks, towers, packing, pumps, exchangers, lines, etc.), can develop a red surface rust coating. Red rust (haematite) accelerates the breakdown of peroxides to peroxy radicals that serve as polymerization initiators.

Another problem encountered in areas where butadiene concentrates, such as the purification section of a butadiene plant, is the presence of popcorn polymer. Popcorn polymer contains active free radicals in the polymer matrix.  If not passivated or “killed,” residual popcorn polymer remaining in the tower can promote further popcorn growth.

Nalco Champion passivation technology is:

  • Effective at low temperatures
  • Easy to apply
  • Easy to monitor
  • Nontoxic

The Nalco Champion passivation procedure includes two steps. The first step is popcorn polymer passivation with an effective popcorn polymer inhibitor. The second step, using the Nalco Champion non-toxic metal passivator, converts the red rust to black rust (magnetite), deactivating the red rust.
