Hydrotreating — Fouling Control

Antifoulant selection for hydrotreating requires a review of the stream, deposit problem and catalyst requirements. Hydrocarbon heat-exchange antifoulants provide a starting point for discussion; suitability for the specific unit must be established before selection.

Application and function

Deposits in heat-exchange equipment can affect operation. Available treatment approaches include dispersion of contaminants in hydrocarbon heat-exchange streams, with selection guided by deposit information.

Review the proposed formulation against the unit’s catalyst requirements and operating configuration. Application-specific compatibility is part of the technical assessment.

Information for selection

  • Feed composition and available deposit information
  • Heat-transfer trends, pressure-drop history and operating conditions
  • Catalyst requirements, injection options and existing treatment

Evaluation and technical review

Agree compatibility checks and evaluation criteria before introducing a treatment. Record site fouling indicators alongside feed and operating changes.

The technical review should determine whether a documented formulation is appropriate and what additional application evidence is needed.
