THE PERCO SOLUTION:
The PERCO gas sweetening process is a highly efficient, cost effective solution for converting “sour” Mercaptan sulfur compounds to non-corrosive, odorless forms. The PERCO gas sweetening process is simplistic in design and operates over a broad range of flow rates and temperatures.
DESCRIPTION:
PERCO is a fixed-bed, copper oxidation catalyst used to sweeten a wide range of hydrocarbon products with varying Mercaptan sulfur levels. Unlike other sweetening catalysts, PERCO is ready-to-use which eliminates the need for in-situ activation.
TYPICAL APPLICATIONS:
Applicable to liquid phase sweetening of:
- Propane
- Butane
- Natural Gasoline
- Straight Run Gasolines
- Mixtures Thereof
PROCESS BACKGROUND:
There are three principal ways to sweeten hydrocarbon products:
- Oxidizing the Mercaptans to disulfides.
- Removal of Mercaptan species.
- Converting and removing other sulfur compounds as well as Mercaptans and hydrogen sulfide.
PERCO sweetens the hydrocarbon product by – Oxidizing the Mercaptans to disulfides affording the following benefits:
- Reduction of Mercaptan content to meet product specifications requiring a negative doctor test or low Mercaptan sulfur content (ppm).
- Elimination of Mercaptan induced corrosivity.
- Odor improvement on all stocks.
