  • How to eliminate erosion and abrasion caused by catalyst fines in FCCU?

    This entry describes how an installed Neles erosion/abrasion resistant ceramic valve solution has helped a customer improve FCC unit performance and profitability. In this particular case eroding 2″ to 10″ valves in a refinery’s fluid catalytic cracking (FCC) unit were causing problems that degraded both productivity and profitability. Neles application engineers analyzed the problem and provided a solution that quickly paid itself back many times over.

  • Upgrading FCC-unit valve controllers without disruption

    In the fluid catalytic cracking (FCC) unit of a large refinery built in the 1940s in the US, a variety of control valve types and brands, along with their proprietary valve controllers, had been installed over the years. This had led to production inconsistency and disruption. The unit wanted to have one type of controller with multiple bracket designs to fit the wide variety of valves in the plant.
