Remove Naphthenic Acid Compounds Without Emulsions

NAPFINING | Caustic Extraction of Naphthenic Acids

Merichem’s NAPFINING technology is a proven solution for removing naphthenic acid compounds from jet fuel, kerosene, diesel, condensate and crude oil streams—without causing debilitating emulsions. As a highly efficient method of mass transfer, NAPFINING uses our proprietary FIBER FILM® Contactor with caustic as the treating reagent.

Advantages

Leveraging the unique features of our FIBER FILM Contactor technology, NAPFINING can significantly reduce space and CAPEX cost requirements for operators. Other dvantages include:

  • Proven, highly efficient pre-treatment process to remove naphthenic and carboxylic acids from heavy naphtha, kerosene, jet fuel. diesel, condensates and light crude oils with minimal emulsion formation
  • Better performance than electrostatic precipitation for emulsion prevention
  • Ideal solution for removal of TAN from hydrocarbons in the range of 0.1 to 1 mg KOH/g or above; has commercially treated up to 0.5 TAN in the feed

FFC Plus Technology

Increase your hydrocarbon treating rates by up to 150% with Merichem’s advanced FIBER FILM® technology.
