Butadiene — Extraction & Distillation
Butadiene extraction and distillation can require treatment to manage unwanted polymer formation and associated deposits. The approach is selected for the process section, solvent system and observed fouling behavior.
Discuss your application
Identify the fouling mechanism
Establish where polymer forms, where it accumulates and how conditions influence the problem. Deposit analyses and equipment observations help identify the treatment requirement.
Available treatment functions include polymerization inhibition with dispersion, and inhibition with oxygen-scavenging functionality. Select the combination for the application.
Review the process conditions
Extraction and distillation sections can have different solvent environments, residence times and treatment-distribution requirements. Evaluate chemistry against the actual stream and addition system.
- Process route, extraction solvent and stream composition
- Temperature profile and deposit locations
- Existing treatment and addition points
- Pressure drop, heat transfer and cleaning history
- Finished-product requirements and downstream restrictions
Agree on an evaluation
Define baseline observations and criteria for reviewing a treatment change. Assess deposit behavior alongside product quality and operating conditions.
Discuss product selection
Share the application, operating conditions and requirements that matter to your evaluation. Product-specific properties, use guidance and handling information are provided in the relevant product data sheet and safety data sheet.
