MERICAT^™ II and MERICAT^™ J technologies are proven solutions for sweetening heavy mercaptans contained in kerosene, jet, middle-distillate and condensate.

When used with Merichem Technologies’ proprietary FIBER FILM^® Contactor high-efficiency mass-transfer device, these technologies reduce the CAPEX and space requirements associated with conventional solutions.

MERICAT^™ II Advantages

Used with a carbon bed, this technology is typically applicable to the treatment of kerosene, jet fuel and middle-distillate streams.

• Reduces mercaptan content
• Uses caustic to meet mercaptan specifications and pass Doctor tests
• Often paired with NAPFINING^™ for removal of naphthenic acids as well as AQUAFINING^™ to scrub sodium and surfactants; uses salt and clay treatment for final polishing

MERICAT^™ J Advantages

Used without a carbon bed, this technology requires no carbon handling, purchase, cleaning, maintenance or disposal costs.

• No carbon fouling or deactivation resulting in off-spec product
• Extremely effective oxidation reactor for heavy or recombinant mercaptans
• Capable of removing naphthenic acids without affecting mercaptan oxidation performance
• Uses proprietary JeSOL^®-9 solution, which provides full lifecycle responsibility by Merichem Technologies
• Eliminates effluent disposal by offering ongoing supply and return of JeSOL^®-9 solution
• Used with FIBER FILM^® Contactor
• Lower cost at high mercaptan levels or high throughput
• Reduced color body formation
• Can often be retrofitted into legacy carbon beds to increase capacity and treatability
