Sweetn'G® is an intermediate process dedicated to Gasoline cut which can use else the SCPS-ready in fixed bed else the LCPS-30 diluted in the caustic depending on client requirements.
This process will selectively convert the acidic mercaptans to neutral disulfides in order to pass the copper strip, doctor test. Heavy sulfur molecules like thiophenes cannot be efficiently removed or transformed by caustic. As a consequence, light naphtha notably from FCCU and H-Oil® are usual feedstocks for a Sweetn'G® process. As a result, the unit scheme is adapted for each client and associated objectives such as meeting gasoline pool sulfur constraints.
Sweetn'G® combines the advantages of Sulfrex™ and Sweetn'K™ technologies thanks to optimized caustic management and without mandatory proprietary equipment. This results in a lower initial investment as well as low operating costs.
