Visbreaking & Coking Applications

Visbreaker and delayed-coker additive selection starts with the operating problem. For fouling-related applications, process treatments can be reviewed against the feed, affected equipment and unit conditions before an application-specific evaluation.

Application and function

The documented treatment scope includes fouling control in delayed cokers and visbreakers. Identify where deposits form and how they affect operation before choosing a chemical approach.

Fouling control and liquid-yield improvement are separate evaluation questions. Define the specific objective and review the feed and operating history alongside the proposed treatment.

Information for selection

  • Feed characteristics and changes associated with deposit formation
  • Affected equipment, operating conditions and fouling history
  • Existing chemical treatment, injection arrangement and evaluation objective

Evaluation and technical review

Establish a baseline for the fouling problem and agree how treatment response will be observed. Record feed and operating changes when reviewing the result.

The proposed formulation and supporting documentation should be reviewed for the service, with broader process-performance objectives evaluated separately.
