Grace technical service engineers regularly visit refineries to review unit operating data, evaluate catalyst management and unit performance, as well as provide specific recommendations to optimise unit operation. Grace can provide expert advice on operational problems concerned with the mechanical integrity of the FCCU. For example, issues such as cyclone performance, stripper efficiencies, circulation problems, transfer line problems, slurry circuit fouling, or high unit erosion can be analysed by our technical service experts.

Grace has introduced an independent critical review service to provide a health check on FCC operations. This feature has been widely appreciated and has assisted with shutdown planning and capital expenditure.

Grace provides regular on-site and off-site workshops specifically created for FCC process engineers covering the following key topics:
- Feedstock Properties
- Heat Balance
- Mass Balance
- Pressure Balance
- Unit Optimisation
- Operating Modes
- Resid Processing
- Troubleshooting Strategy
