Under what circumstances is it cost effective to revamp the FCC main fractionator so that the amount of heavy FCC naphtha feed to ULSD hydrotreaters can be increased while still meeting finished ULSD product flash and distillation requirements? Are most ULSD hydrotreaters designed with a three-product stripper using a fired heater, or is a simple steam stripper adequate?

The stripper design depends on the available stripper feed temperature and extent of heat integration.
Best option is talk to your licensors since design varies from designers to designers.
