丁二烯装置添加剂

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.

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

Define baseline observations and criteria for reviewing a treatment change. Assess deposit behavior alongside product quality and operating conditions.
