MERICAT™ II technology employs the FIBER FILM® Contactor as the mass transfer device and utilizes a caustic/catalyst/air mixture as the treating reagent to remove hydrogen sulfide and sweeten mercaptan compounds in jet fuel, kerosene and gasoline/naphtha streams.

MERICAT™ II technology was first licensed in 1986 and to date Merichem has granted 43 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 MERICAT™ II the technology-of-choice. In addition, the FIBER FILM® Contactor is a built-in pre-wash which protects and extends the life of the carbon bed and in many cases negates the need for a separate upstream pre-wash stage altogether.
