Sweetening

Mercaptans are undesirable and have to be eliminated because of their obnoxious odor and their tendency to hydrolyze, forming toxic and corrosive hydrogen sulfide.

The sweetening of kerosene aims to convert the acidic mercaptans sulfur compounds to neutral disulfides in order to pass the classic tests for mercaptan presence: copper corrosion strip test and the doctor test.

Sweetn’K™

Sweetn'K™ converts Mercaptans directly to RSSR and is used to treat Kerosene through a catalyst fixed bed of SCPS-ready allowing to comply with JET-A1 specification. The unit is made of 3 sections:

A front prewash section, which neutralizes aliphatic acids.
The reaction section where an oxidation reaction converts mercaptans into disulfides. The reaction between mercaptans and air occurs in an alkaline environment in contact with Axens Solutions catalyst “SCPS Ready”.
In the finishing section, the kerosene is dried by a water removal mass and finally upgraded on a clay bed to improve product color.

This process features mild operating conditions:

Low pressure
Ambient temperature

Key features Simple, economic and reliable process
