NAPFINING™ and NAPFINING™ HiTAN technologies employ the FIBER FILM® Contactor as the mass transfer device and utilize caustic as the treating reagent to remove naphthenic acid compounds mainly from jet fuel, kerosene, diesel, condensate and crude oil streams.

NAPFINING™ technologies were first licensed in 1977 and to date Merichem has granted 75 unit operating licenses world-wide. The non-dispersive FIBER FILM® Contactor achieves reduced capital expenditure and less plant space requirements compared to most treating alternatives, making NAPFINING™ and NAPFINING™ HiTAN the technologies-of-choice. In addition, onstream factor between routine turnarounds is 100% whereas electrostatic precipitators (ESPs) are much less reliable and incapable of processing high TAN (> 0.1 mg KOH/g) feeds.
